We have already studied how the market functions when buyers and
sellers are dealing with goods and services: firms supply goods and
services in response to the equilibrium price, and households buy these
goods and services in response to the equilibrium price. The combined effects
of their decisions and behavior determine whether the market equilibrium
stays steady, or if it shifts with changes in the supply and demand
curves.
Similarly, there is a market for labor: individuals decide how willing they
are to supply labor (hours of work), and firms decide how willing they are to
buy labor. (Note that in labor markets supply and demand are the reverse of
that for goods and services markets: in labor markets, firms make up
labor demand, and individuals make up labor supply). The combination of
supply and demand curves for labor determines how much labor is purchased, and
at what price. (Labor price is usually called a wage, the amount of money
paid for a unit of work). Firms decide how much labor they want based on the
wage and the amount of work they need to get done. Individuals decide how much
labor they want to supply based on the wage and the trade-off between
consumption and leisure, as seen in the Labor
Supply unit.
In this unit, we will study Labor Demand: examining the behavior of firms in the
labor market, learning how labor demand curves are determined, and observing
market equilibrium.
