2.Scenario 21
Gertrude Kelp owns three boats that participate in commercial fishing for fresh Pacific salmon off the coast of Alaska. As part of her business she hires a captain and several crew members for each boat. In the market for fresh Pacific salmon, there are thousands of firms like Gertrude's. While Gertrude usually catches a significant number of fish each year, her contribution to the entire harvest of salmon is negligible relative to the size of the market.

Refer to Scenario 21. If Gertrude is a price taker in the labor market, she can choose

5	270
6	300

Refer to Table 22. To maximize its profit, how many workers would the C-Gourmet Burger company employ? Show you work.

Answer 1

Q1. marginal revenue product curve.

​​​​​A perfectly competitive profit maximizing firm demands the labor at the level where the value of marginal product is equal to the nominal wage paid to the labor.

That is

W = P*MPL

where W is wage

P is price of output and

MPL is marginal product of labor

P*MPL is the marginal revenue product.

So, the labor demand curve for a perfectly competitive profit maximizing firm is same as marginal revenue product curve.
