GDP is defined as the total value of all goods and services produced within that territory during a specified period (or, if not specified, annually, so that "''the'' UK GDP" is the UK's annual product). GDP differs from ] (GNP) in excluding inter-country income transfers, in effect attributing to a territory the product ''generated'' within it rather than the incomes ''received'' in it. | |||
== History == | |||
Whereas '''nominal GDP''' refers to the total amount of ] spent on GDP, '''real GDP''' refers to an effort to correct this number for the effects of ] in order to estimate the sum of the actual quantity of goods and services making up GDP. The former is sometimes called "money GDP," while the latter is termed "constant-price" or "inflation-corrected" GDP -- or "GDP in base-year prices" (where the base year is the reference year of the ] used).

The role that measurements of GDP played in World War II was crucial to the subsequent political acceptance of GDP values as indicators of national development and progress.<ref>{{Cite book |last=Lepenies |first=Philipp |url=https://cup.columbia.edu/book/the-power-of-a-single-number/9780231175104 |title=The Power of a Single Number: A Political History of GDP |date=April 2016 |publisher=Columbia University Press |isbn=978-0-231-54143-5 |access-date=2017-10-09 |archive-date=2017-10-20 |archive-url=https://web.archive.org/web/20171020065052/https://cup.columbia.edu/book/the-power-of-a-single-number/9780231175104 |url-status=live }}</ref> A crucial role was played here by the ] under ] where ideas from Kuznets were embedded into ]s. | |||
The history of the concept of GDP should be distinguished from the history of changes in many ways of estimating it. The value added by firms is relatively easy to calculate from their accounts, but the value added by the ], by financial industries, and by ] creation is more complex. These activities are increasingly important in developed economies, and the international conventions governing their estimation and their inclusion or exclusion in GDP regularly change in an attempt to keep up with industrial advances. In the words of one academic economist, "The actual number for GDP is, therefore, the product of a vast patchwork of statistics and a complicated set of processes carried out on the raw data to fit them to the conceptual framework."<ref>{{Cite book |last=Coyle |first=Diane |title=GDP: A Brief but Affectionate History |publisher=Princeton University Press |year=2014 |isbn=978-0-691-15679-8 |pages=6}}</ref> | |||

Economists (since ]) have preferred to split the general consumption term into two parts; private consumption, and ] spending. Two advantages of dividing total consumption this way in theoretical macroeconomics are: | |||
*'''Private consumption''' is a central concern of ]. The private investment and trade portions of the economy are ultimately directed (in mainstream economic models) to increases in long-term private consumption. | |||
*If separated from ] private consumption, '''Government consumption''' can be treated as ], so that different government spending levels can be considered within a meaningful macroeconomic framework. | |||
== Determining gross domestic product (GDP) == | |||
Therefore the formula''' is expressed as: | |||
] | |||
GDP can be determined in three ways, all of which should, theoretically, give the same result. They are the production (or output or value added) approach, the income approach, and the speculated expenditure approach. It is representative of the total output and income within an economy. | |||
: ''GDP = ] + ] + ] + ]'' | |||
: (or simply '''GDP = C + G + I + NX''') | |||
=== Definition of the components of GDP === | |||
The most direct of the three is the production approach, which sums up the outputs of every class of enterprise to arrive at the total. The expenditure approach works on the principle that all of the products must be bought by somebody, therefore the value of the total product must be equal to people's total expenditures in buying things. The income approach works on the principle that the incomes of the productive factors ("producers", colloquially) must be equal to the value of their product, and determines GDP by finding the sum of all producers' incomes.<ref>{{cite web |url-status=dead |publisher=World Bank |work=Statistical Manual |url=http://web.worldbank.org/WBSITE/EXTERNAL/DATASTATISTICS/EXTDECSTAMAN/0,,contentMDK:20882526~menuPK:2648252~pagePK:64168445~piPK:64168309~theSitePK:2077967~isCURL:Y,00.html |title=GDP – Final Output |archive-url=https://web.archive.org/web/20100416073205/http://web.worldbank.org/WBSITE/EXTERNAL/DATASTATISTICS/EXTDECSTAMAN/0,,contentMDK:20882526~menuPK:2648252~pagePK:64168445~piPK:64168309~theSitePK:2077967~isCURL:Y,00.html |archive-date=16 April 2010 |postscript=,}} retrieved October 2009.<br /> | |||
The breakdown of GDP into the variables '''C''', '''I''', '''G''', and '''NX''' helps economists define each part more exactly: | |||

=== Production approach === | |||
*'''C''' is '''private''' consumption (or '''C'''onsumer expenditures) in the economy. This is sometimes clarified as: ''consumer expenditures on ] goods and services''. All the variables in the GDP equation measure ''final'' goods & services expenditures rather than total expenditures; the distinction removes from total expenditure those items which are primarily assets. For instance, buying a ] doesn't boost GDP by $20m. (If it did, buying and selling the same painting repeatedly to a gallery would imply great wealth rather than penury.) Note that the ] purchase would effect the GDP figure, but not as a $20m receipt, the ]'s fees would appear in GDP under '''C'''onsumer expenditure, because this is a ''final'' service. | |||
Also known as the Value Added Approach, it calculates how much value is contributed at each stage of production. | |||
*'''I''' is defined as ] investments in infrastructure, or any other spending intended to generate a subsequent return through business activities. Examples of investment are: training, R&D, ], and recruitment. The word 'investment' here is meant very specifically as non-] purchases. Buying financial products is classed as ] in ]s, as opposed to '''investment''' (which, in the GDP formula is a form of spending). The distinction is (in theory) clear: if money is converted into goods or services, without a repayment ] it ''is'' investment. For example, if you buy a ] or ] the ownership of the money has only nominally changed hands, and this ] is excluded from the GDP sum. Although such purchases would be called ''investments'' in normal speech, from the total-economy point of view, this is simply swapping of ]s, and not part of the ] or the GDP formula. | |||
*'''G''' is the sum of all government expenditures. The ratio of this to GDP as a whole is critical in the theory of ], and the ]. | |||
*'''NX''' are "net exports" in the economy (] exports - gross imports). GDP captures the amount a country produces, including goods and services produced for overseas consumption, therefore exports are added. Imports are subtracted since imported goods will be included in the terms '''G''', '''I''', or '''C''', and must be deducted to avoid counting foreign ] as domestic. This is the concept of ]. | |||
This approach mirrors the ] (Organisation for Economic Co-operation and Development) definition given above. | |||
It is important to understand the meaning of each variable ''precisely'' in order to: | |||
# Estimate the gross value of domestic output out of the many various economic activities; | |||
*Read national accounts. | |||
# Determine the ], i.e., the cost of material, supplies and services used to produce final goods or services. | |||
*Understand ] or ] macroeconomics. | |||
# Deduct intermediate consumption from gross value to obtain the gross value added. | |||
] = gross value of output – value of intermediate consumption. | |||
=== Examples of GDP component variables === | |||
Value of output = value of the total sales of goods and services plus the value of changes in the inventory. | |||
Examples of '''C''', '''I''', '''G''', & '''NX''': If you spend money to renovate your hotel so that occupancy rates increase, that is private investment, but if you buy shares in a consortium to do the same thing it is ]. The former is included when measuring GDP (in '''I'''), the latter is not. | |||
The sum of the gross value added in the various economic activities is known as "GDP at factor cost". | |||
If the hotel is your private home your renovation spending would be measured as '''C'''onsumption, but if a government agency is converting the hotel into an office for civil servants the renovation spending would be measured as part of public sector spending ('''G'''). | |||
GDP at factor cost plus indirect taxes less subsidies on products = "GDP at producer price". | |||
If the renovation involves the purchase of a ] from abroad, that spending would ''also'' be counted as an increase in imports, so that '''NX''' drops and the total GDP is unaffected by the purchase. (This highlights the fact that GDP is intended to measure domestic ] rather than total consumption or spending. Spending is really a convenient means of estimating production.) | |||
For measuring the output of domestic product, economic activities (i.e. industries) are classified into various sectors. After classifying economic activities, the output of each sector is calculated by any of the following two methods: | |||
If you are paid to manufacture the chandelier to hang in a foreign hotel the situation would be reversed, and the payment you receive would be counted in '''NX''' (positively, as an export). Again, we see that GDP is attempting to measure production through the leans of ]; if the chandelier you produced had been bought domestically it would have been included in the GDP figures (in '''C''' or '''I''') when the spending receipts of the purchaser was sampled, but because it was exported it is necessary to 'correct' the amount consumed domestically to give the amount produced domestically. (As in Gross Domestic '''Product'''.). | |||
# By multiplying the output of each sector by their respective market price and adding them together | |||
=== Difference from ] === | |||
# By collecting data on gross sales and inventories from the records of companies and adding them together | |||
The value of output of all sectors is then added to get the gross value of output at factor cost. Subtracting each sector's intermediate consumption from gross output value gives the GVA (=GDP) at factor cost. Adding indirect tax minus subsidies to GVA (GDP) at factor cost gives the "GVA (GDP) at producer prices". | |||
A measure of the economy to GDP is the ] measure, which is identical to GDP except that it '''excludes''' items produced but not purchased (net inventory/stock level growth). If the economy produces more goods than are sold, the increase in inventory would generally be '''included''' in the GDP figure (as "Investment"). This fits into the GDP model by classing the inventory change as "unplanned investment" which will show a return in subsequent years. Technically, GDP is defined as total production quantity multiplied by observed fixed prices for all goods. Where supply exceeds demand it is possible to calculate the 'value' of the additional supply in this way without necessarily explaining why the market has not cleared. | |||
=== |
=== Income approach === | ||
] | |||
The second way of estimating GDP is to use "the sum of primary incomes distributed by resident producer units".<ref name=":0" /> | |||
If GDP is calculated this way it is sometimes called gross domestic income (GDI), or GDP (I). GDI should provide the same amount as the expenditure method described later. By definition, GDI is equal to GDP. In practice, however, measurement errors will make the two figures slightly off when reported by national statistical agencies. | |||
This method measures GDP by adding incomes that firms pay households for factors of production they hire – wages for labour, interest for capital, rent for land and profits for entrepreneurship. | |||
The formula for GDP measured using the income approach, called GDP(I), is: | |||
The US "National Income and Product Accounts" divide incomes into five categories: | |||
: ''GDP = ] + ] + ] + Taxes less subsidies on production and imports'' | |||
# Wages, salaries, and supplementary labor income | |||
# Corporate profits | |||
# Interest and miscellaneous investment income | |||
# Income earned by sole proprietors and from the Housing subsector (net of expenses) | |||
# Net income from transfer payments from businesses | |||
These five income components sum to net domestic income at factor cost. | |||
Two adjustments must be made to get GDP: | |||
*'''Compensation of employees''' (COE) measures the total remuneration to employees for work done. It includes wages and salaries, as well as employer contributions to ] and other such programs. | |||
# Taxes on production and imports minus subsidies are added to get from factor cost to market prices. | |||
*'''Gross operating surplus''' (GOS) is the surplus due to owners of incorporated businesses. Often called ]s, although only a subset of total costs are subtracted from gross output to calculate GOS. | |||
# Depreciation (or ]) is added to get from net domestic product to gross domestic product. | |||
*'''Gross mixed income''' (GMI) is the same measure as GOS, but for unincorporated businesses. This often includes most small businesses. | |||
Total income can be subdivided according to various schemes, leading to various formulae for GDP measured by the income approach. A common one is:{{Citation needed|date=February 2023|reason=Common where?}} | |||
The sum of COE, GOS and GMI is called total factor income, and measures the value of GDP at factor (basic) prices.The difference between basic prices and final prices (those used in the expenditure calculation) is the total taxes and subsidies that the Government has levied or paid on that production. So adding taxes less subsidies on production and imports converts GDP at factor cost to GDP(I). | |||
: '''GDP''' = {{overset|Compensation of employees|'''COE'''}} + {{overset|]|'''GOS'''}} + {{overset|]|'''GMI'''}} + {{overset| taxes less subsidies on production and imports|'''T<sub>P&M</sub>''' − '''S<sub>P&M</sub>'''}} | |||
* '''Compensation of employees''' (COE) measures the total remuneration to employees for work done. It includes wages and salaries, as well as employer contributions to ] and other such programs. | |||
* '''Gross operating surplus''' (GOS) is the surplus due to owners of incorporated businesses. Often called ], although only a subset of total costs are subtracted from ] to calculate GOS. | |||
* '''Gross mixed income''' (GMI) is the same measure as GOS, but for unincorporated businesses. This often includes most small businesses. | |||
The sum of '''COE''', '''GOS''' and '''GMI''' is called total factor income; it is the income of all of the factors of production in society. It measures the value of GDP at factor (basic) prices. The difference between basic prices and final prices (those used in the expenditure calculation) is the total taxes and subsidies that the government has levied or paid on that production. So adding taxes less subsidies on production and imports converts GDP(I) at ] to GDP(I) at final prices. | |||
==Measurement== | |||
===International Standards=== | |||
The international standard for measuring GDP is contained in the book '']'' (1993), which was prepared by representatives of the ], ], ], ] and ]. The publication is normally referred to as SNA93, to distinguish it from the previous edition published in 1968 (called SNA68). | |||
Total factor income is also sometimes expressed as: | |||
SNA93 sets out a set of rules and procedures for the measurement of national accounts. The standards are designed to be flexible, to allow for differences in local statistical needs and conditions. | |||
: ''Total factor income'' = ''employee compensation'' + ''corporate profits'' + ''proprietor's income'' + ''rental income'' + ''net interest''<ref>United States Bureau of Economic Analysis, {{Cite web |title=''A guide to the National Income and Product Accounts of the United States'' |url=https://www.bea.gov/national/pdf/nipaguid.pdf |archive-url=https://web.archive.org/web/20070604184227/http://www.bea.gov/national/pdf/nipaguid.pdf |archive-date=2007-06-04 |url-status=live}}, page 5; retrieved November 2009. Another term, "business current transfer payments", may be added. Also, the document indicates that the capital consumption adjustment (CCAdj) and the inventory valuation adjustment (IVA) are applied to the proprietor's income and corporate profits terms; and CCAdj is applied to rental income.</ref> | |||
=== Expenditure approach === | |||
===National Measurement=== | |||
The third way to estimate GDP is to calculate the sum of the final uses of goods and services (all uses except intermediate consumption) measured in purchasers' prices.<ref name=":0" /> | |||
Within each country GDP is normally measured by a national government statistical agency, as private sector organisations normally do not have access to the information required (especially information on expenditure and production by governments). | |||
Market goods that are produced are purchased by someone. In the case where a good is produced and unsold, the standard accounting convention is that the producer has bought the good from themselves. Therefore, measuring the total expenditure used to buy things is a way of measuring production. This is known as the expenditure method of calculating GDP. | |||

* Canada: ] (StatCan). | |||
* United States: ] (BEA). | |||
==== Components of GDP by expenditure ==== | |||
===Interest rates=== | |||
] | |||
Net interest expense is a ] in all sectors except the financial sector. Net interest expenses in the financial sector is seen as ] and ] and is added to GDP. | |||
'''GDP (Y)''' is the sum of '''consumption (C)''', '''investment (I)''', '''government expenditures (G)''' and '''net exports (X − M)'''. | |||
==Cross-border comparison== | |||
: '''Y''' = '''C''' + '''I''' + '''G''' + '''(X − M)''' | |||
GDPs of different countries may be compared by converting their value in national currency according to ''either'' | |||
*'''current currency exchange rate''': GDP calculated by exchange rates prevailing on international ]s | |||
*'''purchasing power parity exchange rate''': GDP calculated by ] (PPP) of each currency relative to a selected standard (usually the ]). | |||
Here is a description of each GDP component: | |||
The relative ranking of countries may differ dramatically between the two approaches. | |||
* '''C (consumption)''' is normally the largest GDP component in the economy, consisting of private expenditures in the economy (]). These personal expenditures fall under one of the following categories: ]s, nondurable goods, and services. Examples include food, rent, jewelry, gasoline, and medical expenses, but not the purchase of new housing. | |||
* '''I (investment)''' includes, for instance, business investment in equipment, but does not include exchanges of existing assets. Examples include the construction of a new ], the purchase of software, or the purchase of machinery and equipment for a factory. Spending by households (not the government) on new houses is also included in investment. In contrast to its colloquial meaning, "investment" in GDP does not mean purchases related to financial investments. Buying ] is classed as ']', as opposed to investment. This avoids double-counting: if one buys shares in a company, and the company uses the money received to build a plant, purchase equipment, etc., the amount will be counted toward GDP when the company spends the money on those things; to also count it when one gives it to the company would be to count two times an amount that only corresponds to one group of products. Buying ] or companies' ] is a swapping of ]s, a transfer of claims on future production, not directly an expenditure on products; buying an existing building will involve a positive investment by the buyer and a negative investment by the seller, netting to zero overall investment. | |||
* '''G (government spending)''' is the sum of ] on ]s and services. It includes salaries of ], purchases of weapons for the military and any investment expenditure by a government. It does not include any ]s, such as ] or ]. Analyses outside the US will often treat government investment as part of ''investment'' rather than ''government spending''. | |||
* '''X (exports)''' represents gross exports. GDP captures the amount a country produces, including goods and services produced for other nations' consumption, therefore exports are added. | |||
* '''M (imports)''' represents gross imports. Imports are subtracted since imported goods will be included in the terms '''G''', '''I''', or '''C''', and must be deducted to avoid counting foreign ] as domestic. | |||
'''C''', '''I''', and '''G''' are expenditures on ]s and services; expenditures on intermediate goods and services do not count. (Intermediate goods and services are those used by businesses to produce other goods and services within the accounting year.<ref>Thayer Watkins, San José State University Department of Economics, {{Webarchive|url=https://web.archive.org/web/20120825214316/http://www.sjsu.edu/faculty/watkins/gdp.htm |date=2012-08-25 }}, commentary to the first table, " Transactions Table for an Economy". (Page retrieved November 2009.)</ref>) So for example if a ] buys ], assembles the car and sells it, only the final car sold is counted towards the GDP. Meanwhile, if a person buys replacement auto parts to install them on their car, those are counted towards the GDP. | |||
*The ''current exchange rate method'' converts the value of goods and services using global currency ]. This can offer better indications of a country's international purchasing power and relative economic strength. For instance, if 10% of GDP is being spent on buying hi-tech foreign ], the number of weapons purchased is entirely governed by ''current exchange rates'', since arms are a ] bought on the international market (there is no meaningful 'local' price distinct from the international price for high technology goods). | |||
*The ''purchasing power parity method'' accounts for the relative effective domestic purchasing power of the average producer or consumer within an economy. This can be a better indicator of the living standards of less-developed countries because it compensates for the weakness of local currencies in world markets. The PPP method of GDP conversion is most relevant to non-trade goods' and services. | |||
According to the U.S. Bureau of Economic Analysis, which is responsible for calculating the national accounts in the United States, "In general, the source data for the expenditures components are considered more reliable than those for the income components ."<ref>''Concepts and Methods of the United States National Income and Product Accounts'', chap. 2.</ref> | |||
There is a clear pattern of the ''purchasing power parity method'' decreasing the disparity in GDP between high and low income (GDP) countries, as compared to the ''current exchange rate method''. This finding is called the ]. | |||

== GDP and standard of living == | |||
{{Main|National agencies responsible for GDP measurement}} | |||
Within each country GDP is normally measured by a national government statistical agency, as ] organizations normally do not have access to the information required (especially information on expenditure and production by governments). | |||
==== International standards ==== | |||
GDP per capita is often used as an indicator of ] in an ]. While this approach has advantages, many criticisms of GDP focus on its use as an indicator of standard of living. | |||
The international standard for measuring GDP is contained in the book '']'' (2008), which was prepared by representatives of the ], ], ], ] and ]. The publication is normally referred to as SNA2008 to distinguish it from the previous edition published in 1993 (SNA93) or 1968 (called SNA68) <ref name="Central Bureau of Statistics">{{Cite web |title=National Accounts |url=http://www.central-bureau-of-statistics.an/SNA/sna_intro.asp |url-status=dead |archive-url=https://web.archive.org/web/20110416055514/http://www.central-bureau-of-statistics.an/SNA/sna_intro.asp |archive-date=16 April 2011 |access-date=29 June 2011 |publisher=Central Bureau of Statistics}}</ref> | |||
SNA2008 provides a set of rules and procedures for the measurement of national accounts. The standards are designed to be flexible, to allow for differences in local statistical needs and conditions. | |||
The major advantages to using GDP per capita as an indicator of standard of living are that it is measured frequently, widely and consistently. Frequently in that most countries provide information on GDP on a quarterly basis, which allows a user to spot trends more quickly. Widely in that some measure of GDP is available for practically every ] in the ], which allow crude comparisons between the standard of living in different countries to be compared. And consistently in that the technical definitions used within GDP are relatively consistent between countries, and so there can be confidence that the same thing is being measured in each country. | |||
== Nominal GDP and real GDP == | |||
The major disadvantage of using GDP as an indicator of standard of living is that it is not, strictly speaking, a measure of standard of living. GDP is intended to be a measure of particular types of economic activity within a country. Nothing about the definition of GDP suggests that it is necessarily a measure of standard of living. For instance, in an extreme example, a country which exported 100 per cent of its production would still have a high GDP, but a very poor standard of living. | |||
The raw GDP figure given by the equations above is called the nominal, historical, or current GDP. When comparing GDP figures from one year to another, compensating for changes in the value of money—for the effects of inflation or deflation is desirable. To make it more meaningful for year-to-year comparisons, a nominal GDP may be multiplied by the ratio between the value of money in the year the GDP was measured and the value of money in a base year. | |||
For example, suppose a country's GDP in 1990 was {{val|100|u=million|p=$}} and its GDP in 2000 was {{val|300|u=million|p=$}}. Suppose also that inflation had halved the value of its currency over that period. To meaningfully compare its GDP in 2000 to its GDP in 1990, we could multiply the GDP in 2000 by one-half, to make it relative to 1990 as a base year. The result would be that the GDP in 2000 equals {{val|300|u=million|p=$}} × {{1/2}} = {{val|150|u=million|p=$}}, ''in 1990 monetary terms.'' We would see that the country's GDP had realistically increased 50 ] over that period, not 200 percent, as it might appear from the raw GDP data. The GDP adjusted for changes in money value in this way is called the ]. | |||
The argument in favour of using GDP is not that it is a good indicator of standard of living, but rather that (all other things being equal) standard of living tends to increase when GDP per capita increases. This makes GDP a ] for standard of living, rather than a direct measure of it. | |||
The factor used to convert GDP from current to constant values in this way is called the '']''. Unlike ], which measures inflation or deflation in the price of household consumer goods, the GDP deflator measures changes in the prices of all domestically produced goods and services in an economy including investment goods and government services, as well as household consumption goods.<ref>HM Treasury, ''Background information on GDP and GDP deflator''<br /> | |||
There are a number of ] about this use of GDP. | |||

Although GDP is widely used by economists, its value as an indicator has also been the subject of controversy. Criticisms of GDP include: | |||
|- | |||
* GDP doesn't take into account the ], where the money isn't registered, and the non-monetary economy, where no money comes into play at all, resulting in inaccurate or abnormally low GDP figures. For example, in countries with major business transactions occurring informally, portions of local economy are not easily registered. Also, ]ing may be more prominent than the use of money, even extending to services (I helped you build your house ten years ago, so now you help me). In ] this even goes so far that everyone owns the house they live in, but people are only allowed to swap houses, not sell them. | |||
| valign=top | | |||
* Very often different calculations of the GDP are confused among each other. For cross-border comparisons one should especially regard whether it is calculated by ] method or current ] method. | |||

{{Legend|#003c00|$50,000–$60,000}} | |||
* In 'poor' countries, it may just be that ''everything'' is cheap, ]. So one may have little money, but if everything is cheap that evens out nicely. Thus, the ] may be quite reasonable, it's just that there are, say, fewer TV-sets, meaning people have to share them (which may actually increase the ] in a social sense). | |||

The major advantage of GDP per capita as an indicator of the standard of living is that it is measured frequently, widely, and consistently. It is measured frequently in that most countries provide information on GDP every quarter, allowing trends to be seen quickly. It is measured widely in that some measure of GDP is available for almost every country in the world, allowing inter-country comparisons.

Real GDP can be used to calculate the GDP growth rate, which indicates how much a country's production has increased (or decreased, if the growth rate is negative) compared to the previous year, typically expressed as ]. The economic growth can be expressed as ] or ]. | |||
== Relation to GNI == | |||
GDP can be contrasted with ] (GNP) or, as it is now known, ] (GNI). The difference is that GDP defines its scope according to location, while GNI defines its scope according to ownership. In a global context, ] are, therefore, equivalent terms. | |||
GDP is a product produced within a country's borders; GNI is product produced by enterprises owned by a country's citizens. The two would be the same if all of the productive enterprises in a country were owned by its own citizens and those citizens did not own productive enterprises in any other countries. In practice, however, foreign ownership makes GDP and GNI non-identical. Production within a country's borders, but by an enterprise owned by somebody outside the country, counts as part of its GDP but not its GNI; on the other hand, production by an enterprise located outside the country, but owned by one of its citizens, counts as part of its GNI but not its GDP. | |||
For example, the GNI of the ] is the value of output produced by American-owned firms, regardless of where the firms are located. Similarly, if a country becomes increasingly in debt, and spends large amounts of income servicing this debt this will be reflected in a decreased GNI but not a decreased GDP. Similarly, if a country sells off its resources to entities outside their country this will also be reflected over time in decreased GNI, but not decreased GDP. This would make the use of GDP more attractive for politicians in countries with increasing national debt and decreasing assets. | |||
Gross national income (GNI) equals GDP plus income receipts from the rest of the world minus income payments to the rest of the world.<ref>{{Cite book |last1=Lequiller |first1=François |url=https://books.google.com/books?id=pXpJL6f8b3wC&q=%22To+convert+GDP+into+GNI%22 |title=Understanding National Accounts |last2=Derek Blades |publisher=OECD |year=2006 |isbn=978-92-64-02566-0 |page=18 |quote=To convert GDP into GNI, it is necessary to add the income received by resident units from abroad and deduct the income created by production in the country but transferred to units residing abroad. |access-date=2021-02-15 |archive-date=2023-03-12 |archive-url=https://web.archive.org/web/20230312185510/https://books.google.com/books?id=pXpJL6f8b3wC&q=%22To+convert+GDP+into+GNI%22 |url-status=live }}</ref> | |||

You find other examples that amplify differences between GDP and GNI by comparing indicators of developed and developing countries. The GDP of Japan for 2020 was 5.05559 trillion.<ref>{{Cite web |title=Japan GDP 1960-2024 |url=https://www.macrotrends.net/global-metrics/countries/jpn/japan/gdp-gross-domestic-product#google_vignette |website=MacroTrends}}</ref> Predictably, as a developed country, we see a higher GNI of 5.16915 trillion for the same year.<ref>https://www.macrotrends.net/global-metrics/countries/jpn/japan/gni-gross-national-income</ref> An increase of 113.560 million. This being indicative of the production level in the country being higher than that of national production. On the other hand, the case with ] is the opposite with its GDP in 2023 being lower than its GNI by 3.85 billion. This shows us countries receive investments and foreign aid from abroad.<ref>https://www.macrotrends.net/global-metrics/countries/ARM/armenia/gdp-gross-domestic-product</ref><ref>https://www.macrotrends.net/global-metrics/countries/ARM/armenia/gni-gross-national-income</ref> | |||
== Limitations and criticisms == | |||
], the economist who developed the first comprehensive set of measures of national income, stated in his second report to the U.S. Congress in 1937, in a section titled "Uses and Abuses of National Income Measurements":<ref name="kuznets" /> | |||
<blockquote> The valuable capacity of the human mind to simplify a complex situation in a compact characterization becomes dangerous when not controlled in terms of definitely stated criteria. With quantitative measurements especially, the definiteness of the result suggests, often misleadingly, a precision and simplicity in the outlines of the object measured. Measurements of national income are subject to this type of illusion and resulting abuse, especially since they deal with matters that are the center of conflict of opposing social groups where the effectiveness of an argument is often contingent upon oversimplification. | |||
All these qualifications upon estimates of national income as an index of productivity are just as important when income measurements are interpreted from the point of view of economic welfare. But in the latter case additional difficulties will be suggested to anyone who wants to penetrate below the surface of total figures and market values. Economic welfare cannot be adequately measured unless the personal distribution of income is known. And no income measurement undertakes to estimate the reverse side of income, that is, the intensity and unpleasantness of effort going into the earning of income. The welfare of a nation can, therefore, scarcely be inferred from a measurement of national income as defined above.</blockquote> In 1962, Kuznets stated:<ref>Simon Kuznets. "How To Judge Quality". The New Republic, 20 October 1962</ref><blockquote>Distinctions must be kept in mind between quantity and quality of growth, between costs and returns, and between the short and long run. Goals for more growth should specify more growth of what and for what.</blockquote> | |||
GDP as initially defined includes spending on goods and services that would shrink if underlying problems were solved or reduced - for example, medical care, crime-fighting, and the military. During World War II, Kuznets came to argue that military spending should be excluded during peacetime. This idea did not become popular; these activities are tracked because they fit into macroeconomic models (e.g. military spending uses up capital and labor).<ref>{{cite web |url=https://conversableeconomist.com/2019/02/05/why-did-simon-kuznets-want-to-leave-military-spending-out-of-gdp/ |date=February 5, 2019 |website=Conversable Economist |title=Why Did Simon Kuznets Want to Leave Military Spending out of GDP? |author=Timothy Taylor}}</ref> | |||

Furthermore, the GDP does not consider human health nor the educational aspect of a population.<ref>{{Cite web|title=What Are the Advantages & Disadvantages of the GDP in Macroeconomics?|url=https://bizfluent.com/info-8467424-advantages-disadvantages-gdp-macroeconomics.html|access-date=2021-05-07|website=Bizfluent|language=en|archive-date=2021-05-07|archive-url=https://web.archive.org/web/20210507102438/https://bizfluent.com/info-8467424-advantages-disadvantages-gdp-macroeconomics.html|url-status=live}}</ref> | |||

The UK's ] highlighted the shortcomings of GDP in its advice to the ] Government in 2013, pointing out that GDP "focuses on flows, not stocks. As a result, an economy can run down its assets yet, at the same time, record high levels of GDP growth, until a point is reached where the depleted assets act as a check on future growth". They then went on to say that "it is apparent that the recorded GDP growth rate overstates the ] rate. Broader measures of wellbeing and wealth are needed for this and there is a danger that short-term decisions based solely on what is currently measured by national accounts may prove to be costly in the long-term". | |||

In response to these and other limitations of using GDP, alternative approaches have emerged. | |||

=== Problems with GDP data === | |||
* If many products are of low quality in terms of durability then people will have to (unnecessarily) buy them again and again, thus boosting the GDP without increasing their satisfaction. (On the other hand, if products were very durable then that would hamper innovation because people would be less inclined to buy new products, giving producers less of an incentive to develop them.) Similarly, if many products are of low quality in terms of usability and people don't know beforehand which products are the best choice for them, then they will either have to make do with an inferior product or buy again and again until they find something more satisfying. Furthermore, if products have a short lifespan in the market (eg because of fast innovation or fashion) then this process starts all over again when people need a replacement. Note that in a capitalist society these factors working together can easily cause a very high GDP combined with low customer satisfaction. | |||

* GDP doesn't measure the ]. A country may achieve a temporary high GDP by over-exploiting natural resources. Oil rich states can sustain high GDPs without industrializing, but this high level will not be sustainable past the point that the oil runs out. | |||

Market value of goods and services produced within a country "GDP" redirects here. For other uses, see GDP (disambiguation).Gross domestic product (GDP) is a monetary measure of the market value of all the final goods and services produced and rendered in a specific time period by a country or countries. GDP is often used to measure the economic health of a country or region. Several national and international economic organizations maintain definitions of GDP, such as the OECD and the International Monetary Fund.
The ratio of GDP to the total population of the region is the GDP per capita and can approximate a concept of a standard of living. Nominal GDP does not reflect differences in the cost of living and the inflation rates of the countries; therefore, using a basis of GDP per capita at purchasing power parity (PPP) may be more useful when comparing living standards between nations, while nominal GDP is more useful comparing national economies on the international market. Total GDP can also be broken down into the contribution of each industry or sector of the economy.
GDP is often used as a metric for international comparisons as well as a broad measure of economic progress. It is often considered to be the world's most powerful statistical indicator of national development and progress. However, critics of the growth imperative often argue that GDP measures were never intended to measure progress, and leave out key other externalities, such as resource extraction, environmental impact and unpaid domestic work. Alternative economic indicators such as doughnut economics use other measures, such as the Human Development Index or Better Life Index, as better approaches to measuring the effect of the economy on human development and well being.
History
William Petty came up with a concept of GDP, to calculate the tax burden, and argue landlords were unfairly taxed during warfare between the Dutch and the English between 1652 and 1674. Charles Davenant developed the method further in 1695.
The modern concept of GDP was first developed by Simon Kuznets for a 1934 U.S. Congress report, where he warned against its use as a measure of welfare (see below under limitations and criticisms). After the Bretton Woods Conference in 1944, GDP became the main tool for measuring a country's economy. At that time gross national product (GNP) was the preferred estimate, which differed from GDP in that it measured production by a country's citizens at home and abroad rather than its "resident institutional units" (see OECD definition above). The switch from GNP to GDP in the United States occurred in 1991. The role that measurements of GDP played in World War II was crucial to the subsequent political acceptance of GDP values as indicators of national development and progress. A crucial role was played here by the U.S. Department of Commerce under Milton Gilbert where ideas from Kuznets were embedded into institutions.
The history of the concept of GDP should be distinguished from the history of changes in many ways of estimating it. The value added by firms is relatively easy to calculate from their accounts, but the value added by the public sector, by financial industries, and by intangible asset creation is more complex. These activities are increasingly important in developed economies, and the international conventions governing their estimation and their inclusion or exclusion in GDP regularly change in an attempt to keep up with industrial advances. In the words of one academic economist, "The actual number for GDP is, therefore, the product of a vast patchwork of statistics and a complicated set of processes carried out on the raw data to fit them to the conceptual framework."
China officially adopted GDP in 1993 as its indicator of economic performance. Previously, China had relied on a Marxist-inspired national accounting system.
Determining gross domestic product (GDP)
GDP can be determined in three ways, all of which should, theoretically, give the same result. They are the production (or output or value added) approach, the income approach, and the speculated expenditure approach. It is representative of the total output and income within an economy.
The most direct of the three is the production approach, which sums up the outputs of every class of enterprise to arrive at the total. The expenditure approach works on the principle that all of the products must be bought by somebody, therefore the value of the total product must be equal to people's total expenditures in buying things. The income approach works on the principle that the incomes of the productive factors ("producers", colloquially) must be equal to the value of their product, and determines GDP by finding the sum of all producers' incomes.
Production approach
Also known as the Value Added Approach, it calculates how much value is contributed at each stage of production.
This approach mirrors the OECD (Organisation for Economic Co-operation and Development) definition given above.
- Estimate the gross value of domestic output out of the many various economic activities;
- Determine the intermediate consumption, i.e., the cost of material, supplies and services used to produce final goods or services.
- Deduct intermediate consumption from gross value to obtain the gross value added.
Gross value added = gross value of output – value of intermediate consumption.
Value of output = value of the total sales of goods and services plus the value of changes in the inventory.
The sum of the gross value added in the various economic activities is known as "GDP at factor cost".
GDP at factor cost plus indirect taxes less subsidies on products = "GDP at producer price".
For measuring the output of domestic product, economic activities (i.e. industries) are classified into various sectors. After classifying economic activities, the output of each sector is calculated by any of the following two methods:
- By multiplying the output of each sector by their respective market price and adding them together
- By collecting data on gross sales and inventories from the records of companies and adding them together
The value of output of all sectors is then added to get the gross value of output at factor cost. Subtracting each sector's intermediate consumption from gross output value gives the GVA (=GDP) at factor cost. Adding indirect tax minus subsidies to GVA (GDP) at factor cost gives the "GVA (GDP) at producer prices".
Income approach
The second way of estimating GDP is to use "the sum of primary incomes distributed by resident producer units".
If GDP is calculated this way it is sometimes called gross domestic income (GDI), or GDP (I). GDI should provide the same amount as the expenditure method described later. By definition, GDI is equal to GDP. In practice, however, measurement errors will make the two figures slightly off when reported by national statistical agencies.
This method measures GDP by adding incomes that firms pay households for factors of production they hire – wages for labour, interest for capital, rent for land and profits for entrepreneurship.
The US "National Income and Product Accounts" divide incomes into five categories:
- Wages, salaries, and supplementary labor income
- Corporate profits
- Interest and miscellaneous investment income
- Income earned by sole proprietors and from the Housing subsector (net of expenses)
- Net income from transfer payments from businesses
These five income components sum to net domestic income at factor cost.
Two adjustments must be made to get GDP:
- Taxes on production and imports minus subsidies are added to get from factor cost to market prices.
- Depreciation (or capital consumption allowance) is added to get from net domestic product to gross domestic product.
Total income can be subdivided according to various schemes, leading to various formulae for GDP measured by the income approach. A common one is:
- GDP = Compensation of employeesCOE + gross operating surplusGOS + gross mixed incomeGMI + taxes less subsidies on production and importsTP&M − SP&M
- Compensation of employees (COE) measures the total remuneration to employees for work done. It includes wages and salaries, as well as employer contributions to social security and other such programs.
- Gross operating surplus (GOS) is the surplus due to owners of incorporated businesses. Often called profits, although only a subset of total costs are subtracted from gross output to calculate GOS.
- Gross mixed income (GMI) is the same measure as GOS, but for unincorporated businesses. This often includes most small businesses.
The sum of COE, GOS and GMI is called total factor income; it is the income of all of the factors of production in society. It measures the value of GDP at factor (basic) prices. The difference between basic prices and final prices (those used in the expenditure calculation) is the total taxes and subsidies that the government has levied or paid on that production. So adding taxes less subsidies on production and imports converts GDP(I) at factor cost to GDP(I) at final prices.
Total factor income is also sometimes expressed as:
- Total factor income = employee compensation + corporate profits + proprietor's income + rental income + net interest
Expenditure approach
The third way to estimate GDP is to calculate the sum of the final uses of goods and services (all uses except intermediate consumption) measured in purchasers' prices.
Market goods that are produced are purchased by someone. In the case where a good is produced and unsold, the standard accounting convention is that the producer has bought the good from themselves. Therefore, measuring the total expenditure used to buy things is a way of measuring production. This is known as the expenditure method of calculating GDP.
Components of GDP by expenditure
GDP (Y) is the sum of consumption (C), investment (I), government expenditures (G) and net exports (X − M).
- Y = C + I + G + (X − M)
Here is a description of each GDP component:
- C (consumption) is normally the largest GDP component in the economy, consisting of private expenditures in the economy (household final consumption expenditure). These personal expenditures fall under one of the following categories: durable goods, nondurable goods, and services. Examples include food, rent, jewelry, gasoline, and medical expenses, but not the purchase of new housing.
- I (investment) includes, for instance, business investment in equipment, but does not include exchanges of existing assets. Examples include the construction of a new mine, the purchase of software, or the purchase of machinery and equipment for a factory. Spending by households (not the government) on new houses is also included in investment. In contrast to its colloquial meaning, "investment" in GDP does not mean purchases related to financial investments. Buying financial products is classed as 'saving', as opposed to investment. This avoids double-counting: if one buys shares in a company, and the company uses the money received to build a plant, purchase equipment, etc., the amount will be counted toward GDP when the company spends the money on those things; to also count it when one gives it to the company would be to count two times an amount that only corresponds to one group of products. Buying bonds or companies' equity shares is a swapping of deeds, a transfer of claims on future production, not directly an expenditure on products; buying an existing building will involve a positive investment by the buyer and a negative investment by the seller, netting to zero overall investment.
- G (government spending) is the sum of government expenditures on final goods and services. It includes salaries of public servants, purchases of weapons for the military and any investment expenditure by a government. It does not include any transfer payments, such as social security or unemployment benefits. Analyses outside the US will often treat government investment as part of investment rather than government spending.
- X (exports) represents gross exports. GDP captures the amount a country produces, including goods and services produced for other nations' consumption, therefore exports are added.
- M (imports) represents gross imports. Imports are subtracted since imported goods will be included in the terms G, I, or C, and must be deducted to avoid counting foreign supply as domestic.
C, I, and G are expenditures on final goods and services; expenditures on intermediate goods and services do not count. (Intermediate goods and services are those used by businesses to produce other goods and services within the accounting year.) So for example if a car manufacturer buys auto parts, assembles the car and sells it, only the final car sold is counted towards the GDP. Meanwhile, if a person buys replacement auto parts to install them on their car, those are counted towards the GDP.
According to the U.S. Bureau of Economic Analysis, which is responsible for calculating the national accounts in the United States, "In general, the source data for the expenditures components are considered more reliable than those for the income components ."
Encyclopedia Britannica records an alternate way of measuring exports minus imports: notating it as the single variable NX.
National measurement
Main article: National agencies responsible for GDP measurementWithin each country GDP is normally measured by a national government statistical agency, as private sector organizations normally do not have access to the information required (especially information on expenditure and production by governments).
International standards
The international standard for measuring GDP is contained in the book System of National Accounts (2008), which was prepared by representatives of the International Monetary Fund, European Union, Organisation for Economic Co-operation and Development, United Nations and World Bank. The publication is normally referred to as SNA2008 to distinguish it from the previous edition published in 1993 (SNA93) or 1968 (called SNA68)
SNA2008 provides a set of rules and procedures for the measurement of national accounts. The standards are designed to be flexible, to allow for differences in local statistical needs and conditions.
Nominal GDP and real GDP
The raw GDP figure given by the equations above is called the nominal, historical, or current GDP. When comparing GDP figures from one year to another, compensating for changes in the value of money—for the effects of inflation or deflation is desirable. To make it more meaningful for year-to-year comparisons, a nominal GDP may be multiplied by the ratio between the value of money in the year the GDP was measured and the value of money in a base year.
For example, suppose a country's GDP in 1990 was $100 million and its GDP in 2000 was $300 million. Suppose also that inflation had halved the value of its currency over that period. To meaningfully compare its GDP in 2000 to its GDP in 1990, we could multiply the GDP in 2000 by one-half, to make it relative to 1990 as a base year. The result would be that the GDP in 2000 equals $300 million × 1⁄2 = $150 million, in 1990 monetary terms. We would see that the country's GDP had realistically increased 50 percent over that period, not 200 percent, as it might appear from the raw GDP data. The GDP adjusted for changes in money value in this way is called the real GDP.
The factor used to convert GDP from current to constant values in this way is called the GDP deflator. Unlike consumer price index, which measures inflation or deflation in the price of household consumer goods, the GDP deflator measures changes in the prices of all domestically produced goods and services in an economy including investment goods and government services, as well as household consumption goods.
GDP per capita
> $60,000 $50,000–$60,000 $40,000–$50,000 $30,000–$40,000 | $20,000–$30,000 $10,000–$20,000 $5,000–$10,000 $2,500–$5,000 | $1,000–$2,500 < $1,000 No data |
GDP can be adjusted for population growth, also called Per-capita GDP or GDP per person. This measures the average production of a person in the country. Lists of GDP per capita:
The major advantage of GDP per capita as an indicator of the standard of living is that it is measured frequently, widely, and consistently. It is measured frequently in that most countries provide information on GDP every quarter, allowing trends to be seen quickly. It is measured widely in that some measure of GDP is available for almost every country in the world, allowing inter-country comparisons. It is measured consistently in that the technical definition of GDP is relatively consistent among countries.
It can be argued that GDP per capita is an indicator of standard of living. As a result, GDP per capita as a standard of living is a continued usage because most people have a fairly accurate idea of what it is and know it is tough to come up with quantitative measures for such constructs as happiness, quality of life, and well-being. From the perspective of environmental, social and governance (ESG) measures, GDP per capita trends can be influenced by factors such as gender parity and elements of regulatory quality. The change in number of MSMEs (Micro, Small, and Medium Enterprises) in the Philippines from 2008 through 2021 would be an example of elements such as the per capita gross domestic product and unemployment rate having significant effect on a developing country with mixed economy.
Economic growth
Further information: Economic growthbelow -3.0 -3.0 to -2.1 -2.0 to -1.1 -1.0 to -0.1 0.0 to 0.9 | 1.0 to 1.9 2.0 to 2.9 3.0 to 3.9 4.0+ no data |
Real GDP can be used to calculate the GDP growth rate, which indicates how much a country's production has increased (or decreased, if the growth rate is negative) compared to the previous year, typically expressed as percentage change. The economic growth can be expressed as real GDP growth rate or real GDP per capita growth rate.
Relation to GNI
GDP can be contrasted with gross national product (GNP) or, as it is now known, gross national income (GNI). The difference is that GDP defines its scope according to location, while GNI defines its scope according to ownership. In a global context, world GDP and world GNI are, therefore, equivalent terms.
GDP is a product produced within a country's borders; GNI is product produced by enterprises owned by a country's citizens. The two would be the same if all of the productive enterprises in a country were owned by its own citizens and those citizens did not own productive enterprises in any other countries. In practice, however, foreign ownership makes GDP and GNI non-identical. Production within a country's borders, but by an enterprise owned by somebody outside the country, counts as part of its GDP but not its GNI; on the other hand, production by an enterprise located outside the country, but owned by one of its citizens, counts as part of its GNI but not its GDP.
For example, the GNI of the US is the value of output produced by American-owned firms, regardless of where the firms are located. Similarly, if a country becomes increasingly in debt, and spends large amounts of income servicing this debt this will be reflected in a decreased GNI but not a decreased GDP. Similarly, if a country sells off its resources to entities outside their country this will also be reflected over time in decreased GNI, but not decreased GDP. This would make the use of GDP more attractive for politicians in countries with increasing national debt and decreasing assets.
Gross national income (GNI) equals GDP plus income receipts from the rest of the world minus income payments to the rest of the world.
In 1991, the United States switched from using GNP to using GDP as its primary measure of production. The relationship between United States GDP and GNP is shown in table 1.7.5 of the National Income and Product Accounts.
You find other examples that amplify differences between GDP and GNI by comparing indicators of developed and developing countries. The GDP of Japan for 2020 was 5.05559 trillion. Predictably, as a developed country, we see a higher GNI of 5.16915 trillion for the same year. An increase of 113.560 million. This being indicative of the production level in the country being higher than that of national production. On the other hand, the case with Armenia is the opposite with its GDP in 2023 being lower than its GNI by 3.85 billion. This shows us countries receive investments and foreign aid from abroad.
Limitations and criticisms
Simon Kuznets, the economist who developed the first comprehensive set of measures of national income, stated in his second report to the U.S. Congress in 1937, in a section titled "Uses and Abuses of National Income Measurements":
The valuable capacity of the human mind to simplify a complex situation in a compact characterization becomes dangerous when not controlled in terms of definitely stated criteria. With quantitative measurements especially, the definiteness of the result suggests, often misleadingly, a precision and simplicity in the outlines of the object measured. Measurements of national income are subject to this type of illusion and resulting abuse, especially since they deal with matters that are the center of conflict of opposing social groups where the effectiveness of an argument is often contingent upon oversimplification. All these qualifications upon estimates of national income as an index of productivity are just as important when income measurements are interpreted from the point of view of economic welfare. But in the latter case additional difficulties will be suggested to anyone who wants to penetrate below the surface of total figures and market values. Economic welfare cannot be adequately measured unless the personal distribution of income is known. And no income measurement undertakes to estimate the reverse side of income, that is, the intensity and unpleasantness of effort going into the earning of income. The welfare of a nation can, therefore, scarcely be inferred from a measurement of national income as defined above.
In 1962, Kuznets stated:
Distinctions must be kept in mind between quantity and quality of growth, between costs and returns, and between the short and long run. Goals for more growth should specify more growth of what and for what.
GDP as initially defined includes spending on goods and services that would shrink if underlying problems were solved or reduced - for example, medical care, crime-fighting, and the military. During World War II, Kuznets came to argue that military spending should be excluded during peacetime. This idea did not become popular; these activities are tracked because they fit into macroeconomic models (e.g. military spending uses up capital and labor).
Ever since the development of GDP, multiple observers have pointed out limitations of using GDP as the overarching measure of economic and social progress. Furthermore, the GDP does not consider human health nor the educational aspect of a population.
Instances of GDP measures have been considered numbers that are artificial constructs. American politician Robert F. Kennedy criticized GDP (or GNP), listing many examples of bad things it does count and good things it does not count:
Gross National Product counts air pollution and cigarette advertising, and ambulances to clear our highways of carnage. It counts special locks for our doors and the jails for the people who break them. It counts the destruction of the redwood and the loss of our natural wonder in chaotic sprawl. It counts napalm and counts nuclear warheads and armored cars for the police to fight the riots in our cities. It counts Whitman's rifle and Speck's knife, and the television programs which glorify violence in order to sell toys to our children. Yet the gross national product does not allow for the health of our children, the quality of their education or the joy of their play. It does not include the beauty of our poetry or the strength of our marriages, the intelligence of our public debate or the integrity of our public officials. It measures neither our wit nor our courage, neither our wisdom nor our learning, neither our compassion nor our devotion to our country, it measures everything in short, except that which makes life worthwhile. And it can tell us everything about America except why we are proud that we are Americans.
Unpaid work
GDP excludes the value of household and other unpaid work. Some, including Martha Nussbaum, argue that this value should be included in measuring GDP, as household labor is largely a substitute for goods and services that would otherwise be purchased with money. Even under conservative estimates, the value of unpaid labor in Australia has been calculated to be over 50% of the country's GDP. A later study analyzed this value in other countries, with results ranging from a low of about 15% in Canada (using conservative estimates) to high of nearly 70% in the United Kingdom (using more liberal estimates). For the United States, the value was estimated to be between about 20% on the low end to nearly 50% on the high end, depending on the methodology being used. Because many public policies are shaped by GDP calculations and by the related field of national accounts, public policy might differ if unpaid work were included in total GDP. Some economists have advocated for changes in the way public policies are formed and implemented.
Some have pointed out that GDP did not adapt to sociotechnical changes to give a more accurate picture of the modern economy and does not encapsulate the value of new activities such as delivering price-free information and entertainment on social media. In 2017 Diane Coyle explained that GDP excludes much unpaid work, writing that "many people contribute free digital work such as writing open-source software that can substitute for marketed equivalents, and it clearly has great economic value despite a price of zero", which constitutes a common criticism "of the reliance on GDP as the measure of economic success" especially after the emergence of the digital economy.
GDP and assets
The UK's Natural Capital Committee highlighted the shortcomings of GDP in its advice to the UK Government in 2013, pointing out that GDP "focuses on flows, not stocks. As a result, an economy can run down its assets yet, at the same time, record high levels of GDP growth, until a point is reached where the depleted assets act as a check on future growth". They then went on to say that "it is apparent that the recorded GDP growth rate overstates the sustainable growth rate. Broader measures of wellbeing and wealth are needed for this and there is a danger that short-term decisions based solely on what is currently measured by national accounts may prove to be costly in the long-term".
Health
In 2013 scientists reported that large improvements in health only lead to modest long-term increases in GDP per capita. After developing an abstract metric similar to GDP, the Center for Partnership Studies highlighted that GDP "and other metrics that reflect and perpetuate them" may not be useful for facilitating the production of products and provision of services that are useful – or comparatively more useful – to society, and instead may "actually encourage, rather than discourage, destructive activities". The number of obese adults was approximately 600 million (12%) in 2015.
Environment
See also: Eco-economic decouplingMany environmentalists argue that GDP is a poor measure of social progress because it does not take into account harm to the environment.
In the language of economics, everything comes down to its monetary value. In essence, GDP rewards behaviors that are detrimental to the environment. GDP also does not capture certain phenomena impacting citizens' well-being. For example, traffic jams could cause GDP to increase as there is a higher consumption of gasoline, however, GDP fails to consider citizens' well-being in terms of the quality of air due to air pollution from the traffic jams. Various alternatives have been developed(see below).
A 2020 study found that "poor regions' GDP grows faster by attracting more polluting production after connection to China's expressway system. GDP may not be a tool capable of recognizing how much natural capital agents of the economy are building or protecting. In 2020 scientists, as part of a World Scientists' Warning to Humanity-associated series, warned that worldwide growth in affluence in terms of GDP-metrics has increased resource use and pollutant emissions with affluent citizens of the world – in terms of e.g. resource-intensive consumption – being responsible for most negative environmental impacts and central to a transition to safer, sustainable conditions. They summarised evidence, presented solution approaches and stated that far-reaching lifestyle changes need to complement technological advancements and that existing societies, economies and cultures incite consumption expansion and that the structural imperative for growth in competitive market economies inhibits societal change. Sarah Arnold, Senior Economist at the New Economics Foundation (NEF) stated that "GDP includes activities that are detrimental to our economy and society in the long term, such as deforestation, strip mining, overfishing and so on". The number of trees that are net lost annually is estimated to be approximately 10 billion. The global average annual deforested land in the 2015–2020 demi-decade was 10 million hectares and the average annual net forest area loss in the 2000–2010 decade 4.7 million hectares, according to the Global Forest Resources Assessment 2020. According to one study, depending on the level of wealth inequality, higher GDP-growth can be associated with more deforestation. In 2019 "agriculture and agribusiness" accounted for 24% of the GDP of Brazil, where a large share of annual net tropical forest loss occurred and is associated with sizable portions of this economic activity domain.
Steve Cohen of the Earth Institute elucidated that while GDP does not distinguish between different activities (or lifestyles), "all consumption behaviors are not created equal and do not have the same impact on environmental sustainability". Johan Rockström, director of the Potsdam Institute for Climate Impact Research, noted that "it's difficult to see if the current G.D.P.-based model of economic growth can go hand-in-hand with rapid cutting of emissions", which nations have agreed to attempt under the Paris Agreement in order to mitigate real-world impacts of climate change.
In 1989, John B. Cobb and Herman Daly introduced Index of Sustainable Economic Welfare (ISEW) by taking into account other factors such as consumption of nonrenewable resources and degradation of the environment. ISEW is roughly defined as: personal consumption + public non-defensive expenditures − private defensive expenditures + capital formation + services from domestic labour − costs of environmental degradation − depreciation of natural capital. In 2005, Med Jones, an American Economist, at the International Institute of Management, introduced the first secular Gross National Happiness Index a.k.a. Gross National Well-being framework and Index to complement GDP economics with additional seven dimensions, including environment, education, and government, work, social and health (mental and physical) indicators. The proposal was inspired by the King of Bhutan's GNH philosophy. In 2019, Serge Pierre Besanger published a "GDP 3.0" proposal which combines an expanded GNI formula which he calls GNIX, with a Palma ratio and a set of environmental metrics based on the Daly Rule.
Standard of living
Although a high or rising level of GDP is often associated with increased economic and social progress, the opposite sometimes occurs. For example, Jean Drèze and Amartya Sen have pointed out that an increase in GDP or in GDP growth does not necessarily lead to a higher standard of living, particularly in areas such as healthcare and education. Another important area that does not necessarily improve along with GDP is political liberty, which is most notable in China, where GDP growth is strong yet political liberties are heavily restricted. GDP does not account for the distribution of income among the residents of a country, because GDP is merely an aggregate measure. An economy may be highly developed or growing rapidly, but also contain a wide gap between the rich and the poor in a society. These inequalities often occur on the lines of race, ethnicity, gender, religion, or other minority status within countries. This can lead to misleading characterizations of economic well-being if the income distribution is heavily skewed toward the high end, as the poorer residents will not directly benefit from the overall level of wealth and income generated in their country (their purchasing power can decline, even as the mean GDP per capita rises). GDP per capita measures (like aggregate GDP measures) do not account for income distribution (and tend to overstate the average income per capita). For example, South Africa during apartheid ranked high in terms of GDP per capita, but the benefits of this immense wealth and income were not shared equally among its citizens. The United Nations has aimed in its Sustainable Development Goals, amongst other global initiatives, to address wealth inequality.
GDP does not include several factors that influence the standard of living. In particular, it fails to account for:
- Externalities – Economic growth may entail an increase in negative externalities that are not directly measured in GDP. Increased industrial output might grow GDP, but any pollution is not counted.
- Non-market transactions – GDP excludes activities that are not provided through the market, such as household production, bartering of goods and services, and volunteer or unpaid services.
- Non-monetary economy – GDP omits economies where no money comes into play at all, resulting in inaccurate or abnormally low GDP figures. For example, in countries with major business transactions occurring informally, portions of local economy are not easily registered. Bartering may be more prominent than the use of money, even extending to services.
- Quality improvements and inclusion of new products – by not fully adjusting for quality improvements and new products, GDP understates true economic growth. For instance, although computers today are less expensive and more powerful than computers from the past, GDP treats them as the same products by only accounting for their monetary value. The introduction of new products is also difficult to measure accurately and is not reflected in GDP although it may increase the standard of living. For example, even the richest person in 1900 could not purchase standard products, such as antibiotics and cell phones, that an average consumer can buy today, since such modern conveniences did not exist then.
- Sustainability of growth – GDP is a measurement of economic historic activity and is not necessarily a projection.
- Income distribution – GDP does not account for variances in incomes of various demographic groups. See income inequality metrics for discussion of a variety of inequality-based economic measures.
Proposals to overcome GDP limitations
In response to these and other limitations of using GDP, alternative approaches have emerged.
- In the 1980s, Amartya Sen and Martha Nussbaum developed the capability approach, which focuses on the functional capabilities enjoyed by people within a country, rather than the aggregate wealth held within a country. These capabilities consist of the functions that a person is able to achieve.
- In 1990, Mahbub ul Haq, a Pakistani economist at the United Nations, introduced the Human Development Index (HDI). The HDI is a composite index of life expectancy at birth, adult literacy rate and standard of living measured as a logarithmic function of GDP, adjusted to purchasing power parity.
- In 2009 the European Union released a communication titled GDP and beyond: Measuring progress in a changing world that identified five actions to improve indicators of progress in ways that make them more responsive to the concerns of its citizens.
- In 2009 Professors Joseph Stiglitz, Amartya Sen, and Jean-Paul Fitoussi at the Commission on the Measurement of Economic Performance and Social Progress (CMEPSP), formed by French President, Nicolas Sarkozy published a proposal to overcome the limitation of GDP economics to expand the focus to well-being economics with a well-being framework consisting of health, environment, work, physical safety, economic safety, and political freedom. This has been adopted in a number of countries as a wellbeing economy policy.
- In 2008, the Centre for Bhutan Studies began publishing the Bhutan Gross National Happiness (GNH) Index, whose contributors to happiness include physical, mental, and spiritual health; time balance; social and community vitality; cultural vitality; education; living standards; good governance; and ecological vitality.
- In 2013, the OECD Better Life Index was published by the OECD. The dimensions of the index included health, economic, workplace, income, jobs, housing, civic engagement, and life satisfaction.
- Since 2012, John Helliwell, Richard Layard and Jeffrey Sachs have edited an annual World Happiness Report which reports a national measure of subjective well-being, derived from a single survey question on satisfaction with life. GDP explains some of the cross-national variation in life satisfaction, but more of it is explained by other, social variables (See 2013 World Happiness Report).
- In 2019, Erik Brynjolfsson and Avinash Collis argued that GDP does not reflect the growing value of many digital goods because they have zero price. Along with several coauthors, they proposed an alternative approach, GDP-B, which is based on measuring the benefits of goods and services, rather than their price or cost.
- At the beginning of the 21st century the World Economic Forum published a series of analyses and propositions to create economic measurement tools more effective than GDP.
- China launched the Gross Ecosystem Product (GEP) in 2020. It measures the contribution of ecosystems to the economy, including by regulating climate. It spread widely across the country. The first province to issue local rules about GEP was Zhejiang , and a year later it has already decided the fate of a project in the Deqing region. For example, the GEP of Chengtian Radon Spring Nature Reserve has been calculated as US$43 million.
Problems with GDP data
See also: Economic dataA peer-reviewed study published in the Journal of Political Economy in October 2022 found signs of manipulation of economic growth statistics in the majority of countries. According to the study, this mainly applied to countries that were governed semi-authoritarian/authoritarian or did not have a functioning separation of powers. The study took the annual growth in the brightness of lights at night, as measured by satellites, and compared it to officially reported economic growth. Authoritarian states had consistently higher reported growth in GDP than their growth in night lights would suggest. An effect that also cannot be explained by different economic structures, sector composition or other factors. Incorrect growth statistics can also falsify indicators such as GDP or GDP per capita.
It has been suggested that countries that have authoritarian governments, such as the People's Republic of China, and Russia, inflate their GDP figures.
Corporate havens can have a distorted GDP.
