Refer to the following figure. Suppose a firm spends $4,000 per day producing a good. The wage rate per worker is $400 per day and rental rate per unit of capital is $1,000 per day. The firm’s isocost line at the current expenditure level is represented by

Suppose that the inverse demand in a market is P = 100 – 2Q. A firm’s marginal cost is constant and equal to $50. If the marginal cost increased from $50 to $60 and the firm is a monopoly, then it would raise its price _____. If the marginal cost increased from $50 to $60 and the firm operates in a perfectly competitive market, then the market price would _____.

The demand and supply of detergent are given by QD = 7,000 – 1,000P and QS = 1,000P – 1,000, where P is price per gallon and Q is in gallons. What happens at a price ceiling of $2 per gallon?

A firm is producing 8 units of output at an average total cost of $40. When the firm produces 9 units of output, average total cost rises to $54. What is the marginal cost of the 9th unit of output?

In a perfectly competitive industry, the equilibrium price is $10, and the minimum average total cost of the industry’s firms is $20. If this is a constant-cost industry, we can expect that in the long run, firms will _____ the market, shifting the industry’s short-run supply curve _____.

In the market for apartment rentals, the demand and supply equations are given by QD = 5,000 – 3P and QS = 5P + 1,000, where P is the price per apartment and Q measures the quantity of apartments. What is the equilibrium quantity?

A firm is producing 4 units of output at an average total cost of $10. When the firm produces 5 units of output, average total cost rises to $20. What is the marginal cost of the fifth unit of output?

If a firm has market power but cannot prevent its customers from reselling the product, then the firm will

Suppose the supply curve for backpacks is Q = 2P – 36. What is the highest price at which no producer is willing to sell backpacks (i.e., the supply choke price)?
