10 Market Chapter Power and Monopoly 1) SA10 \ \\ Price Discrimination and Efficiency\ 1 \\ Explain why price discrimination reduces the economic inefficiency associated with the exercise of monopoly power. Draw simple graphs to show how this occurs. 2) SA10 \ \\ Profit Maximization\ 1 \\ Consider a market in which economic profit is currently possible, but entry and exit are possible in the long run. [I.e., the current situation is the short run.] Each firm in this market has some power as a price maker. In the space below, draw a demand [D] curve a for firm, and a set of appropriate MR, MC, AVC, and ATC curves. Clearly identify the areas that represent total profit, total cost, total variable cost, and total fixed cost. [Use such letters as a, b, c, d, e, f, g, etc. to identify points in this graph, and then use, ex, abdc to identify these areas.] Solution: Area pcab equal...
