Chapter 13. Labor Markets

Why do people earn what they do?

Key concepts:

equilibrium in the labor market

value of marginal product

monopsony

minimum wage effects

living wage campaigns

human capital theory

labor market discrimination

labor unions

winner-take-all markets

compensating wage differentials

customer and employer discrimination

comparable worth

First, let’s review how the forces of supply and demand in the labor market create an equilibrium wage, taking the market for college graduates as an example.

Now, let’s experiment with some possible factors that could shift the supply and demand for labor in ways that might affect wages--

a recession tends to shift the demand for labor to the left

immigration tends to shift the supply of labor to the right

capital mobility (specifically, relocation of plants overseas) tends to shift the supply of labor to the right

The minimum wage sets a floor under wages. The current federal minimum is $5.15 an hour; in real purchasing power, it is lower than it was in 1955.

Living wage campaigns are local efforts to increase minimum wages.

Do minimum wages and living wages cause unemployment? If so, do they create so much unemployment that this cancels out the benefits they provide? Probably they CAN have negative effects IF they are set VERY high.

The market determines the wage an individual employer must pay. An employer continues hiring workers as long as the value of their marginal product is higher than the wage.

Monopsony–a market with only a single buyer.

Example of monopsony in the labor market–a "company town"
