1. Assume that labor demand for low-skilled workers in the United States is: w = 22 – 0.1E where E is the number of workers (in millions) and w is the hourly wage. Assume there are currently 120 million domestic U.S. low-skilled workers who supply labor inelastically. If the U.S. opened its borders to immigration, 20 million low-skilled workers would enter the U.S. and supply labor inelastically.

a. What is the market-clearing wage if immigration is not allowed?

b. What is the market-clearing wage with open borders?

c. How much is the immigration surplus when the U.S. opens its borders?

Homework Answers

Answer #1

Labor demand: w = 22 - 0.1E

0.1E = 22 - w

E = 220 - 10w

Market is cleared when labor demand equals labor supply. Inelastic labor supply means that supply of labor is fixed.

(a) When immigration is not allowed, labor supplied = 120 million

220 - 10w = 120

10w = 100

w = $10

E = 120

(b) When immigration is allowed, labor supplied = (120 + 20) million = 140 million

220 - 10w = 140

10w = 80

w = $8

E = 140

(c) Immigration surplus = (1/2) x Change in wage rate x Change in employment

= (1/2) x $(10 - 8) x (140 - 120) Million

= (1/2) x $2 x 20 Million

= $20 Million

Consider a low-wage labour market. Workers in this market are not presently covered by the minimum wage, but the government is considering implementing such legislation. If implemented, this law would require employers in the market to pay workers a $5 hourly wage. Suppose all workers in the market are equally productive, the current market clearing wage rate is $4 per hour, and that at this market clearing wage there are 600 employed workers. Further suppose that under the minimum wage...
