A profit-maximizing firm should keep on hiring labor as long as the marginal revenue product of labor is greater than the wage. True or False

Solutions

Expert Solution

Answer: TRUE. The marginal revenue product (MRP) also known as marginal value product of a labor is equal to the product of the marginal product of labor, MP (the increase in output from an increase in labor used) and the marginal revenue, MR (the increase in revenue from an increase in output): MRP = MP × MR. The theory states that for a profit-maximizing firm labors will be hired up to the point when the marginal revenue product is equal to the wage rate. If the marginal revenue brought by the laborer is less than the wage rate, then employing that laborer would cause a decrease in profit. This theory assumes that the expenditures on other factors remain unchanged.

Lets understand this with an example:

A Sports Apparel Company wants to know whether to hire another worker for producing more caps. If the extra worker can eventually produce 10 additional caps per day (MP), and each additional cap sells at the market for $5 (price of the product or marginal revenue), the MRP of the labor is $50. Holding other considerations constant, company will only hire an additional worker at wage rate of $50 per day only if he generates an additional revenue of $50 or more. Otherwise, it will take a loss.

A profit-maximizing monopolist charges a price of $36. The intersection of the marginal revenue and marginal cost curves occurs where output is 20,000 units and marginal cost is $24. Average total cost for 20,000 units of output is $32. As a result, the monopolist’s profit is more than $80,000. true or false The continuous downward slope of the average total cost curve suggests that the profit-maximizing natural monopolist is able to exploit economies of scale to keep competitors from successfully...

When a profit-maximizing firm in a monopolistic competitive market is in long-run equilibrium, marginal cost is rising since an increase in production would increase average total cost. true or false The product-variety externality associated with monopolistic competition arises because in markets that are monopolistic competitive markets, firms try to differentiate their products. true or false If the monopolistic competitive firm is currently producing output at a level where the marginal cost curve intersects the demand curve, then it is producing...
