Figure 26.2 Refer to Figure 26.2 for a monopolistically competitive firm. At the profit-maximizing output: price, this firm is O Earning an economic loss. Breaking even. Earning a monopoly profit. Earning an economic profit.

Assume you see the graph of a monopolistically competitive firm. In the graph, at the output where MR MC, the average total cost curve dips below the demand curve. Which of the following statements is correct? The firm's total cost is greater than its total revenue. The firm is definitely in the short run. The firm could have an economic breakeven. O The firm has an economic loss.

Figure 10.5 shows the demand, marginal revenue, and cost curves for a monopolistically competitive firm. At the profit-maximizing (or loss-minimizing) output and price, the firm would: Figure 10.5. Price 3.25 3.00 2.50 0 700 Quantity 1,000 MC MR ATC D AR be earning zero economic profit. be earning an economic profit. be earning an economic loss. be better off shutting down since total revenue does not cover fixed costs. O have to expand to stay in business in the long run.

Beatrice's Birthday Cakes operates in a monopolistically competitive market, so it is one bakery among many in the market for birthday cakes. The following table presents cost and revenue data for birthday cakes at Beatrice's.

The graph illustrates an industry in which many firms operating in perfect competition are taken over by one firm that operates as a single-price monopoly. Draw the following shapes: 1) the consumer surplus arising from monopoly. Label it CS. 2) the deadweight loss arising from monopoly. Label it DWL 3) the loss of consumer surplus that is a gain to the monopoly as producer surplus. Label it Monopoly's gain. Indicate whether each of the following statements is true or false. At the competitive equilibrium, marginal social benefit equals marginal social cost. At the competitive equilibrium, the sum of consumer surplus and producer surplus is maximized. At the long-run competitive equilibrium, firms produce at the lowest possible long-run average cost. 30- 25- 20 15- 10- 5- Price and cost (dollars per haircut) 0+ 0.0 MR 1.0 2.0 3.0 4.0 Quantity (thousands of haircuts) MSC 5.0

Monopolistically competitive firms have a "monopoly" element to them because Multiple Choice O O O O brand loyalty gives them a captive audience. there are high barriers to entry. the cross-price elasticity is very high. there is only one seller.

O both short-run and long-run equilibrium because price equals marginal cost at the profit-maximizing output level.
