Gross domestic product (GDP) is a monetary measure of the market value [1] of all the final goods and services produced and rendered in a specific time period by a country [2] or countries. [3] [4] [5] GDP is often used to measure the economic health of a country or region. [2]
A variety of measures of national income and output are used in economics to estimate total economic activity in a country or region, including gross domestic product (GDP), Gross national income (GNI), net national income (NNI), and adjusted national income (NNI adjusted for natural resource depletion – also called as NNI at factor cost).
The structure of the input–output model has been incorporated into national accounting in many developed countries, and as such can be used to calculate important measures such as national GDP. Input–output economics has been used to study regional economies within a nation, and as a tool for national and regional economic planning.
For oil-export-dependent economies, there could be substantial differences between real GDP and real GDI, due the effect of oil price volatility on the purchasing power in those countries. [1] [2] In the United States National Income and product accounts, the word GDI is use to define GDP calculated with income data rather than expenditure data ...
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.
TFP is calculated by dividing output by the weighted geometric average of labour and capital input, with the standard weighting of 0.7 for labour and 0.3 for capital. [3] Total factor productivity is a measure of productive efficiency in that it measures how much output can be produced from a certain amount of inputs.
Like the consumer price index (CPI), the GDP deflator is a measure of price inflation/deflation with respect to a specific base year; the GDP deflator of the base year itself is equal to 100. Unlike the CPI, the GDP deflator is not based on a fixed basket of goods and services; the "basket" for the GDP deflator is allowed to change from year to ...
If capital's share in output is 1 ⁄ 3, then labor's share is 2 ⁄ 3 (assuming these are the only two factors of production). This means that the portion of growth in output which is due to changes in factors is .06×(1 ⁄ 3)+.01×(2 ⁄ 3)=.027 or 2.7%. This means that there is still 0.3% of the growth in output that cannot be accounted for.
