  1. Labor market and the minimum wage: Assume that workers are all alike and that firms maximize profit. If the labor market were perfectly competitive, the equilibrium wage would be $10/hr. If the labor market were monopsonistic, the equilibrium wage would be $8/hr.

    1. First assume a perfectly competitive labor market. Show (using a demand-supply graph) what happens to total employment if a $9/hr minimum wage is enforced by the government.

    2. Again assuming a perfectly competitive labor market, show (using a demand-supply graph) what happens to total employment if a $20/hr minimum wage is enforced by the government.

    3. Now assume that the labor market is monopsonistic. Discuss what will happen (no need to show demand-supply graph) to total employment if a $9/hr minimum wage is enforced by the government.

    4. Again assuming a monopsonistic case, discuss what will happen (no need to show demand- supply graph) to total employment if a $20/hr minimum wage is enforced by the government.

Solutions

Expert Solution

1. When minimum wage is at $9, demand for labour is greater than supply of labour thereby creating labour shortage.

2. When minimum wage is at $20, supply of labour is greater than demand for labour thereby creating labour surplus.

3. In the monopsonistic market, the equilibrium wage is $8.

If the minimum wage is $9, then Marginal Factor Cost = $9.

In the monopsonisitc market with no minimum wage, the employer faced a upward sloping MFC, but with minimum wages, the employer faces a constant MFC of $9, thus every additional labourer has to be paid only $9.

Therefore, the labour demanded by a monopsonist increases with a minimum wage

Since minimum wage ($9 ) is greater than monopsony wage ( $8), labour supplied increases.

At $9, labour supplied < labour demanded

4. At minimum wage = $20, MFC = $20

MFC cuts MRC at a very low labour demand level. But labour supplied at $20 is very high

Hence, at minimum wage = $20, labour demand < labour supplied ----> surplus labour

(monopsonist chooses that quantity of labour where MFC = MRP)

A. Minimum Wage in a Single Competitive Labor Market In a single competitive labor market, the labor demand and labor supply curves are LD = 200 − 20w LS = 50 + 10w where we measure labor in terms of workers per hour, and the hourly wage is measured in dollars per worker.

In the labor market the wage rate requested by workers will generally depend on workers’ expected price Pe which is to prevail in the future, the current unemployment rate u, and a variable z that represents the unemployment benefits package. This defines the wage-setting relationship: W = PeF(u,z). At the same time, firms define the price-setting relationship: P = (1+m)W, where m is the markup of goods prices over wage rate. (1) Suppose we know the functional form F(u,z) =...
