Economic Growth: The Aggregate Production Function
An aggregate production function (PF) relates total output to total employment, assuming all other factors of production and technology are fixed. It shows that increases in employment lead to increases in output but at a decreasing rate. It is easy to picture the problem of diminishing marginal returns in the context of a single firm.
