Real GDP is a measure of the final goods and services produced in a year valued at constant prices. Nominal GDP is the final goods and services produced in a year valued at the prices that existed during the year. Economists make the distinction between real GDP and nominal GDP because nominal GDP changes for two reasons: When the production of goods and services changes and when the prices of the goods and services change. Economists want to be able to distinguish between changes brought about by production changes and changes brought about by price changes. Real GDP allows economists to make this distinction. In particular, by using prices that are constant, a change in real GDP represents a change in the production of goods and services and factors out the change in prices. Thus real GDP removes the effect from changes in prices and thereby reveals the change in the underlying production of goods and services.
