What is the labor market? Like the goods and services markets, a labor market consists of the supply and demand sides. In the labor market, while workers supply labor, firms demand labor. This chapter studies the backward-bending nature of the labor supply curve and the downward-sloping nature of the labor demand curve. We also analyze the labor market equilibrium in a perfectly competitive labor market. Several policies such as immigration and minimum wage will be introduced to illustrate how government policies affect the labor market equilibrium.
