Definition

GDP is defined as the total value of all goods and services produced within that territory during a specified period (most commonly, per year). GDP differs from gross national product in excluding inter-country income transfers, in effect attributing to a territory the product generated within it rather than the incomes received in it. Whereas nominal GDP refers the total amount of money spent on GDP, real GDP refers to an effort to correct this number for the effects of inflation 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 chosen arbitrarily). See real vs. nominal in economics. A common equation for GDP is:

GDP = consumption + investment + government expenditures + exports - imports

Aggregate expenditures are calculated in a similar way, although the aggregate expenditures formula does not account for unplanned investment (left over inventory at the end of the reporting cycle) and is more commonly used by economic theorists. GDPs of different countries may be compared by converting their value in national currency according to either \n*current exchange rate method: GDP calculated by exchange rates prevailing on international currency markets\n*purchasing power parity method: GDP calculated by purchasing power parity (PPP) of each currency relative to a selected standard (usually the United States dollar). The relative ranking of countries may differ dramatically between the two approaches. 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 current exchange rate method converts the value of goods and services using global currency exchange rates. This can offer better indications of a country's international purchasing power and relative economic power. For more information see measures of national income.

Problems

\n \nAlthough GDP is widely used by economists, its value as an indicator has also been the subject of controversy. Criticisms of GDP include:

• Very often different calculations of the GDP are confused among each other. One should especially regard whether it is calculated by purchasing power parity method or current exchange rate method.\n* GDP, as a measure of economic size, fails to measure well-being and living standards accurately.\n* GDP doesn't take into account the black economy, non-monetary economy such as bartering, volunteer work, or informal creation of wealth, such as unpaid childcare provided by non-working parents.\n* GDP doesn't measure the sustainability of growth, as a country may achieve a temporary high GDP by over-exploiting natural resources.\n* GDP counts work that produces no net gain, and does not account for negative externalities. For example, if a factory pollutes a river, that boosts GDP, and when the taxpayers pay to have it cleaned up, that boosts GDP again. See parable of the broken window.

The methodology for deriving accurate PPP comparisons remains under constant review, and questions have been raised as to whether the relative size of Mainland China's GDP may be overstated to some extent.
