34、on and stability of a cartel?a.High barriers to entry b.An identical product c.Similar costs Answer:a.A successful cartel implies positive profits.Positive profits attract entry,if it is possible,and increasing the number of firms in the industry erodes the cartels control and pricing power(or makes

35、 it more difficult to negotiate with the larger number of firms in the industry).b.If products are not identical,then consumers may have brand preferences,and thus it is possible for firms to cheat on the cartel by promoting nonprice differences.c.If costs are similar,profits are similar,and the inc

36、entives of each firm will be similar,all other things equal.This makes it easier to agree on price and more fair in the sense that firms will receive similar profits.2)Industry demand is given by:QD=1000-P All firms in the industry have identical and constant marginal and average costs of$50/unit.a.

37、If the industry is perfectly competitive,what will industry output be?What will be the equilibrium price?What profit will each firm earn?b.Now suppose that there are five firms in the industry,and that they collude to set price.What price will they set?What will be the output of each firm?What will

38、be the profit of each firm?Answer:a.P=50,so Q=950.Each firm earns an economic profit of zero.b.MR=1000-2Q.Set MR=MC 50=1000-2Q Q=475 P=$525 Each firm produces 1/5 the output,or q=95.Profit for each firm is$45,125.3)Why do cartels tend to break up?Answer:There are many reasons,but one of the best is

39、that there is an incentive to cheat.While the cartel maximizes joint profits,individual profit could be increased if the firm could sell more at the cartel price.If everyone does that,output increases and the price falls.10 4)A monopolist sells to two consumer groups,students and non-students.Demand

40、 for students:Q=500-1/2P Demand for non-students:Q=750-2P MC=20 Find the profit-maximizing price/quantity combination in each market if the groups can be separated.Answer:Students:P=1000-2Q MR=1000-4Q Set MR=MC.20=1000-4Q 245=Q,P=$510 Non-students:P=375-1/2 Q MR=375-Q Set MR=MC.20=375-Q 355=Q,P=$197

41、.50 5)McDonalds charges a higher price for a Big Mac in New York City than it does in a small town in Iowa.Is this an example of third-degree price discrimination?Explain.Answer:No,or not necessarily.Costs differ between the two markets,because land is more expensive in New York City.Thus the higher

42、 price reflects that.6)Some charge that third-degree price discrimination is unfair or that it reduces social welfare.Why does charging one group a lower price hurt anyone?Answer:Theres an equity issue about charging different prices to different people,but the real social welfare issue is not about

43、 charging a lower price to one group;its about charging a higher price to the other.If the firm charged a single price,it would be somewhere in between the two group prices,in most cases.So some customers who would be able to buy at a lower price in the combined market pay more(or do not buy at all)

44、in the separated market.7)Firms that make game systems like Playstation and Nintendo typically charge a price close to average cost on the game system itself,and do not change that price even when the systems are scarce or demand increases.Why might this be a profit-maximizing strategy?Answer:These

45、firms are selling two products,the systems and the games.These are complementary products.If they increase the price of the systems,they reduce the demand for games(and games are repeat purchases rather than one-time purchases).Additionally,the system is the hook,or the loss leader that draws custom

46、ers in.Once you have the system,the switching cost of moving to another system is significant.Thus the systems are cheap,and the games are expensive.11 8)In the Sunday newspaper,there are usually coupons that you can clip and take to the store to save money on products.Anyone can buy a newspaper,and

47、 the value of the coupons easily exceeds the price of the newspaper for most consumers.Is this an example of price discrimination?Explain.Answer:Yes,it is.Consumers with more time are likely to have a more elastic demand for products,and thus they are willing to clip the coupons(and may not buy exce

48、pt at the lower price).Other consumers with less time wont deal with the coupons and thus will pay a higher price.This is essentially the same idea as movie matinee pricing.9)Would it ever make sense for a firm to charge a price at or below the cost of the product?Answer:This might be an example of

49、penetration pricing in which the firm is trying to gain market share.(Two other reasons not discussed in the text:limit pricing to prevent entry,and predatory pricing to drive out rivals.)10)Superstar actors typically get contracts that specify that they get a percentage of the gross,the total reven

50、ues that the movie brings in.Why might actors want contracts structured that way?Why might producers be willing to agree to that,and how does this make the goals of actors and producers different?Answer:Actors want to maximize revenue with this sort of contract,while producers wish to maximize profi
