Real GDP is an example of the distinction between real and nominal values in economics.Nominal gross domestic product is defined as the market value of all final goods produced in a geographical region, usually a country; this depends on the quantities of goods and services produced, and their respective prices.
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.
Arriving at a figure for the total production of goods and services in a large region like a country entails a large amount of data-collection and calculation. Although some attempts were made to estimate national incomes as long ago as the 17th century, [ 2 ] the systematic keeping of national accounts , of which these figures are a part, only ...
Thus the left side gives GDP by the income method, and the right side gives GDP by the expenditure method. The GDP is given on the bottom line of both sides of the report. GDP must have the same value on both sides of the account. This is because income and expenditure are defined in a way that forces them to be equal (see accounting identity ...
Gross domestic product (GDP) is a measure of aggregate output. Nominal GDP in a particular period reflects prices that were current at the time, whereas real GDP compensates for inflation. Price indices and the U.S. National Income and Product Accounts are constructed from bundles of commodities and their respective prices.
In most countries, the difference between GDP and GNI are modest so that GDP can approximately be treated as total income of all the inhabitants as well, but in some countries, e.g. countries with very large net foreign assets (or debt), the difference may be considerable. [5]: 385
From a microeconomic standpoint, expansion usually means enlarging the scale of a single company or firm. This can be achieved through internal actions—opening branches, finding new customers, inventing products, developing lines of business—and through integration, for example, taking over or merging with other companies.
If the inputs are indivisible and complementary, a small scale may be subject to idle times or to the underutilization of the productive capacity of some sub-processes. A higher production scale can make the different production capacities compatible. The reduction in machinery idle times is crucial in the case of a high cost of machinery. [10]
