Document Summary

Real labor market: shows quantity of labor demanded and supplied for every real wage. A firm will hire another worker if additional benefits > additional costs. Firms hire up to the point where mrp = w. Real wage: w = w (p 0 / p t ) Horizontal sum of firms" labor demand curves. If w increases, each firm reduces employment so mpl matches w. Anything that shifts mpl will shift aggregate labor demand. Change in the quantity of a factor other than labor. Compare benefits of working and value of not working. Opportunity cost of not working is higher when real wage increases. Since more income is earned per hour, individual consumes more normal goods, including leisure. Individual household"s labor supply curve is backward-bending. Some people do not have a backward-bending portion. For those who do, the bend occurs at different values of w. As w rises, additional people are pulled into the labor market.

Suppose a firm employs both labor and capital. If the ratio of marginal product to price of labor is 50/$10 and the ratio of marginal product of capital to price of capital is 60/$12, the firm should
