A case study in this chapter discusses the federal minimum-wage law. a. Suppose the minimum wage is above the equilibrium wage in the market for unskilled labor. Using a supply-and-demand diagram of the market for unskilled labor, show the market wage, the number of workers who are employed, and the number of workers who are unemployed. Also show the total wage payments to unskilled workers. b. Now suppose the secretary of labor proposes an increase in the minimum wage. What effect would this increase have on employment? Does the change in employment depend on the elasticity of demand, the elasticity of supply, both elasticities, or neither? c. What effect would this increase in the minimum wage have on unemployment? Does the change in unemployment depend on the elasticity of demand, the elasticity of supply, both elasticities, or neither? d. If the demand for unskilled labor were inelastic, would the proposed increase in the minimum wage raise or lower total wage payments to unskilled workers? Would your answer change if the demand for unskilled labor were elastic?

Key Concepts

Total Wage Payments

Total wage payments in the labor market are calculated by multiplying the wage rate by the number of workers employed. Changes in the minimum wage can alter both the wage rate and the level of employment, resulting in different aggregate wage outcomes depending on how these two factors adjust in response to the policy.

Minimum Wage

The minimum wage is a legally established lower limit on the wage that employers can pay their workers. It acts as a price floor in the labor market, and when set above the equilibrium wage, it can lead to a surplus of labor (unemployment) as well as changes in the distribution of wages and employment levels.

Labor Market Equilibrium

Labor market equilibrium is the state where the quantity of labor supplied equals the quantity demanded by employers. This intersection determines the natural wage rate and the level of employment without any government-imposed interventions like a minimum wage.

Supply and Demand Analysis in the Labor Market

This is the framework used to analyze how wages and employment levels are determined through the intersection of the labor supply and labor demand curves. When a minimum wage is imposed above the equilibrium, it causes a disruption in this balance, leading to a surplus of workers (unemployment) and affecting overall wage payments.

Elasticity of Demand for Labor

The elasticity of demand for labor refers to how sensitive employers are to changes in the wage rate. When labor demand is elastic, small increases in wages lead to relatively larger decreases in employment, whereas if demand is inelastic, changes in wages have a less significant impact on employment levels.

Elasticity of Supply for Labor

The elasticity of supply for labor measures how responsive the number of workers willing to work is to changes in wages. A more elastic labor supply means that a wage increase will attract significantly more workers, which can exacerbate the effects of a minimum wage by increasing the surplus of labor if employers do not adjust their demand accordingly.

00:02 This figure shows the effect of the minimum wage.

00:07 In the absence of the minimum wage, the market wage would be w1 and q1 workers would be employed.

00:16 With the minimum wage, wm, imposed above w1, the market wage is wm and the number of employed workers is q2.

00:37 Q3 is the number of workers.

00:42 That are willing to be employed at this minimum wage, but they can't.

00:56 Therefore, we have unemployment, which is the difference between q3 and q2.

01:13 Total wage payments to workers are shown as the area of rectangle a, b, c, d.

01:27 So this is a, b, c and d.

01:50 And this area equals wm times q2.

02:03 That is part a of the question.

02:07 For part b, b and c actually, assume there is an increase in the minimum wage.

02:17 We can draw another line.

02:21 Let's say wm prime is the new minimum wage.

02:32 Now the number of workers would be employed.

02:35 Are q2 prime and the number of workers that are willing to work is q3 prime.

02:49 You can see that the difference between these two quantities increase.

02:55 So the new level of unemployment is q3 prime minus q2 prime that is greater than the initial unemployment when we first impose the minimum wage.

03:18 The size of the effect of a higher minimum wage on employment depends only on the elasticity of demand.

03:30 The elasticity of supply does not matter because there is a surplus of labor.

03:44 Let me write down for part b, employment decrease.

03:51 For part c, unemployment, increase.

03:55 The size of the rise in unemployment depends on both the elasticity of supply and demand.

04:06 The elasticity of demand determines the change in the quantity of labor demanded, and the elasticity of supply determines the change in the quantity of labor supplied...
