A firm’s technology requires it to combine 5 person-hours of labor with 3 machinehours to produce 1 unit of output. The firm has 15 machines in place and the wage rate rises from $10 per hour to $20 per hour. What is the firm’s short-run elasticity of labor demand?
A firm faces a perfectly elastic demand for its output at a price of $6 per unit of output. The firm, however, faces an upward-sloped labor supply curve ofE = 20w - 120where E is the number of workers hired each hour and w is the hourly wage rate. Thus, the firm faces an upward-sloped marginal cost of labor curve ofMCE = 6 + 0.1EEach hour of labor produces five units of output. How many workers should the firm hire each hour to maximize profits? What wage will the firm pay? What are the firm’s hourly profits?
Explain the relationship between the own-wage elasticity of labor demand and
output demand elasticity.

The firm’s elasticity of demand for labor is -0.4. Suppose the wage increases by 5 percent. What will happen to the number of workers hired by the firm?

Then determine whether the following statement is true or false: "If women's labor supply in an economy is more elastic than that of men, it would be easier for firms to induce women workers to accept jobs."

- In the demand for labor for a firm was expressed as L = N x average hours per employee per day. Assume a firm has 50 employees that average 6 hours per day for 300 man-hours per day. A minimum wage is passed and reduces demand to 240 man-hours per day. Answer the following questions. a. How many layoffs are required if average hours per employee are not reduced? Explain. b. If no layoffs are made, what would the average hours per employee be set to?
