Answer:
real GDP.
Explanation:
GDP is defined as the monetary value of all goods and services produced in an economy within a give time period. It is a measure of how productive an economy is.
Real GDP considers market prices of commodities in relation to a base year.
For example if 2012 is considered to be the base year for real GDP this year, all goods and services are multiplied by the prices as at 2012 to get the monetary value of goods and services for the present year.
Base year prices are referred to as constant prices when calculating real GDP.
