.................................................................................
In economics, the marginal product of labor (MPL) is the change in output that results from employing an added unit of labor.[1] It is a feature of the production function, and depends on the amounts of physical capital and labor already in use.
The marginal product of labor is then the change in output (Y) per unit change in labor (L). In discrete terms the marginal product of labor is: (Y2-Y1)/(L2-L1)
