b) (4 points) Graph demand, marginal revenue, marginal cost and average total cost (ATC) below. Mark Q*, P*, ATC* (you’ll have to calculate it) and the endpoints to all of the curves.
c) (2 points) Given your answers above, explain which curve(s) will shift in the long run and why.
d) (4 points) Draw the graph that represents this firm in the long-run. Label the profit-maximizing price and quantity as P* and Q*, respectively. No numbers are necessary, but be sure that the curves are drawn so they properly relate to each other.

The graph to the right shows the Marginal Cost (MC), Average Total Cost (ATC), and Marginal Revenue (MR) curves for a perfectly (or purely) competitive firm. Note that the Demand (D) curve is the same as the MR curve for such a MR/MC ($) firm. Assume that the cost curves here are representative of other firms in the industry. Given the current price, this firm will: earn a positive profit. earn a negative profit. earn zero economic profit. In the...
Suppose that a firm produces baseball bats in a monopolistically competitive market. The following graph shows its demand curve, marginal revenue (MR) curve, marginal cost (MC) curve, and average total cost (ATC) curve.
3. Is monopolistic competition efficient? Suppose that a firm produces baseball bats in a monopolistically competitive market. The following graph shows its demand curve, marginal revenue (MR) curve, marginal cost (MC) curve, and average total cost (ATC) curve. Place a black point (plus symbol) on the graph to indicate the long-run monopolistically competitive equilibrium price and quantity for this firm. Next, place a grey point (star symbol) to indicate the minimum average total cost the firm faces and the quantity associated with...
Consider the competitive market for halogen lamps. The following graph shows the marginal cost (MC), average total cost (ATC), and average variable cost (AVC) curves for a typical firm in the industry.
Consider the competitive market for halogen lamps. The following graph shows the marginal cost (MC), average total cost (ATC), and average variable cost (AVC) curves for a typical firm in the industry. For each price in the following table, use the graph to determine the number of lamps this firm would produce in order to maximize its profit. Assume that when the price is exactly equal to the average variable cost, the firm is indifferent between producing zero lamps and the...
