Why do we use gdp instead of gnp

The GDP of a country tends to increase when the total value of goods and services that domestic producers sell to foreign countries exceeds the total value of foreign goods and services that domestic consumers buy. When this situation occurs, a country is said to have a trade surplus. If the opposite situation occurs—if the amount that domestic consumers spend on foreign products is greater than the total sum of what domestic producers are able to sell to foreign consumers—it is called a trade deficit.

In this situation, the GDP of a country tends to decrease. GDP can be computed on a nominal basis or a real basis, the latter accounting for inflation.

Overall, real GDP is a better method for expressing long-term national economic performance since it uses constant dollars. In this example, if you were to look solely at the nominal GDP, the economy appears to be performing well.

GDP can be reported in several ways, each of which provides slightly different information. Nominal GDP is an assessment of economic production in an economy that includes current prices in its calculation.

All goods and services counted in nominal GDP are valued at the prices that those goods and services are actually sold for in that year. Nominal GDP is evaluated in either the local currency or U. Nominal GDP is used when comparing different quarters of output within the same year. This is because, in effect, the removal of the influence of inflation allows the comparison of the different years to focus solely on volume.

Real GDP is an inflation-adjusted measure that reflects the quantity of goods and services produced by an economy in a given year, with prices held constant from year to year to separate out the impact of inflation or deflation from the trend in output over time.

Since GDP is based on the monetary value of goods and services, it is subject to inflation. Real GDP is calculated using a GDP price deflator , which is the difference in prices between the current year and the base year. Real GDP accounts for changes in market value and thus narrows the difference between output figures from year to year. It indicates that the amount of output or income per person in an economy can indicate average productivity or average living standards.

GDP per capita can be stated in nominal, real inflation-adjusted , or PPP purchasing power parity terms. At a basic interpretation, per-capita GDP shows how much economic production value can be attributed to each individual citizen. This also translates to a measure of overall national wealth since GDP market value per person also readily serves as a prosperity measure.

Therefore, it can be important to understand how each factor contributes to the overall result and is affecting per-capita GDP growth. Some countries may have a high per-capita GDP but a small population, which usually means they have built up a self-sufficient economy based on an abundance of special resources. Usually expressed as a percentage rate, this measure is popular for economic policy-makers because GDP growth is thought to be closely connected to key policy targets such as inflation and unemployment rates.

Conversely, central banks see a shrinking or negative GDP growth rate i. GDP can be determined via three primary methods.

All three methods should yield the same figure when correctly calculated. These three approaches are often termed the expenditure approach, the output or production approach, and the income approach.

The expenditure approach, also known as the spending approach, calculates spending by the different groups that participate in the economy.

The U. GDP is primarily measured based on the expenditure approach. This approach can be calculated using the following formula:. All of these activities contribute to the GDP of a country. Consumption refers to private consumption expenditures or consumer spending. Consumers spend money to acquire goods and services, such as groceries and haircuts.

Consumer spending is the biggest component of GDP, accounting for more than two-thirds of the U. Consumer confidence, therefore, has a very significant bearing on economic growth. A high confidence level indicates that consumers are willing to spend, while a low confidence level reflects uncertainty about the future and an unwillingness to spend. Government spending represents government consumption expenditure and gross investment.

Governments spend money on equipment, infrastructure, and payroll. This may occur in the wake of a recession, for example. Investment refers to private domestic investment or capital expenditures. Businesses spend money to invest in their business activities. For example, a business may buy machinery. Business investment is a critical component of GDP since it increases the productive capacity of an economy and boosts employment levels.

All expenditures by companies located in a given country, even if they are foreign companies, are included in this calculation. The production approach is essentially the reverse of the expenditure approach. Instead of measuring the input costs that contribute to economic activity, the production approach estimates the total value of economic output and deducts the cost of intermediate goods that are consumed in the process like those of materials and services.

Whereas the expenditure approach projects forward from costs, the production approach looks backward from the vantage point of a state of completed economic activity. The income approach represents a kind of middle ground between the two other approaches to calculating GDP.

The income approach calculates the income earned by all the factors of production in an economy, including the wages paid to labor, the rent earned by land, the return on capital in the form of interest, and corporate profits.

The income approach factors in some adjustments for those items that are not considered payments made to factors of production. For one, there are some taxes—such as sales taxes and property taxes —that are classified as indirect business taxes. In addition, depreciation —a reserve that businesses set aside to account for the replacement of equipment that tends to wear down with use—is also added to the national income.

Although GDP is a widely used metric, there are other ways of measuring the economic growth of a country. While GDP measures the economic activity within the physical borders of a country whether the producers are native to that country or foreign-owned entities , gross national product GNP is a measurement of the overall production of people or corporations native to a country, including those based abroad. GNP excludes domestic production by foreigners. Gross national income GNI is another measure of economic growth.

It is the sum of all income earned by citizens or nationals of a country regardless of whether the underlying economic activity takes place domestically or abroad.

With GNI, the income of a country is calculated as its domestic income, plus its indirect business taxes and depreciation as well as its net foreign factor income. The figure for net foreign factor income is calculated by subtracting all payments made to foreign companies and individuals from all payments made to domestic businesses.

In an increasingly global economy, GNI has been put forward as a potentially better metric for overall economic health than GDP. The World Bank. Central Intelligence Agency. Actively scan device characteristics for identification.

Gross domestic product GDP is the value of a nation's finished domestic goods and services during a specific time period. A related but different metric, the gross national product GNP , is the value of all finished goods and services owned by a country's residents over a period of time.

Both GDP and GNP are two of the most commonly used measures of a country's economy, both of which represent the total market value of all goods and services produced over a defined period.

There are differences between how each one defines the scope of the economy. While GDP limits its interpretation of the economy to the geographical borders of the country, GNP extends it to include the net overseas economic activities performed by its nationals. Gross domestic product is the most basic indicator used to measure the overall health and size of a country's economy. It is the overall market value of the goods and services produced domestically by a country.

GDP is an important figure because it gives an idea of whether the economy is growing or contracting. Calculating GDP includes adding together private consumption or consumer spending, government spending, capital spending by businesses, and net exports—exports minus imports. Here's a brief overview of each component:. Because it is subject to pressures from inflation, GDP can be broken up into two categories—real and nominal.

A country's real GDP is the economic output after inflation is factored in, while nominal GDP is the output that does not take inflation into account. It is used to compare different quarters in a year. GDP can be used to compare the performance of two or more economies, acting as a key input for making investment decisions in a country. It also helps government draft policies to drive local economic growth. When the GDP rises, it means the economy is growing.
