Economic growth
1. Economic growth is the increase in the amount of the goods and services produced by an economy over time. It is conventionally measured as the percent rate of increase in real gross domestic product, or real GDP. Growth is usually calculated in real terms, i.e. inflation-adjusted terms, in order to obviate the distorting effect of inflation on the price of the goods produced. In economics, «economic growth» or «economic growth theory» typically refers to growth of potential output, i.e., production at «full employment».
2. As an area of study, economic growth is generally distinguished from development economics. The former is primarily the study of how countries can advance their economies. The latter is the study of the economic aspects of the development process in low-income countries. Since economic growth is measured as the annual percent change of gross domestic product (GDP), it has all the advantages and drawbacks of that measure.
3. Economic growth is measured as a percentage change in the Gross Domestic Product (GDP) or Gross National Product (GNP). These two measures, which are calculated slightly differently, total the amounts paid for the goods and services that a country produced. As an example of measuring economic growth, a country which creates $9,000,000,000 in goods and services in 2010 and then creates $9,090,000,000 in 2011, has a nominal economic growth rate of 1% for 2011.
