  • The Aggregate Production Function

    The aggregate production function has several key properties. First, output increases when there are increases in physical capital, labor, and natural resources. In other words, the marginal products of these inputs are all positive. Second, the increase in output from adding more inputs is lower when we have more of a factor. This is called diminishing marginal product. That is, .
