The graph above shows the demand (D), marginal revenue (MR), marginal cost (MC), and average total cost (ATC)
curves for one of many profit-maximizing firms operating in the short run in an industry in which there are no barriers to
entry. Each firm sells a similar but not identical product.
(a) Assume the firm produces 40 units. Will the firm's economic profit be positive, negative, or zero? Explain.
(b) If the firm charges $32, should this firm increase its price, decrease its price, or keep the price at $32 in order to
maximize its total revenue? Explain.
(c) If the firm decreases its price from $72 to $64, does the deadweight loss increase, decrease, or remain unchanged?
Explain.
