The aggregate production function describes how total real gross domestic product (real GDP) in an economy depends on available inputs. Aggregate output (real GDP) depends on the following: Physical capital—machines, production facilities, and so forth that are used in production. Labor—the number of hours that are worked in the entire economy.
An aggregate production function is an economic model that represents the relationship between the total output of a nation and the amounts of various inputs used to produce that output. It is a theoretical concept that describes how, in the economy as a whole, total gross domestic product (GDP) is affected by levels of labor, capital ...
