- Consider the model of the market for lemons from Chapter 22. Suppose that there are two types of used cars — good ones and lemons — and that sellers know which type of car they have. Buyers do not know which type of car a seller has. The fraction of used cars of each type is 21 and buyers know this. Let’s suppose that a seller who has a good car values it at $10,000 and a seller with a lemon values the lemon at $5,000. A seller is willing to sell his car for any price greater than or equal to his value for the car; the seller is not willing to sell the car at a price below the value of the car. Buyers’ values for good cars and lemons are $14,000 and $8,000, respectively. As in Chapter 22 we will assume that buyers are risk-neutral; that is, they are willing to pay their expected value of a car.

- An insurance company is looking to provide a full coverage health insurance plan to the 10 professors in the economics department at the University of Alabama. Seven of these professors are in great health and will incur no medical expenses this year. Six professors have chronic conditions which require $5000 of medical care per year for each professor. a. If the insurance company is looking to insure the entire group, what will be the actuarially fair premium it charges? b. If professors have the option to enroll in the insurance plan, what will be the profit to the insurance company if it charges the premium in part (a)? c.

Young values going to party at $10. The cost of the risk of getting Corona from going to the party is $1 for Young. However, the cost to Old of getting Corona from Young if he goes to the party is $20. a. Suppose there is no bargaining and that Young doesn't care about Old. What is Young's privately optimal action, Party or No Party? b. Given the answer to (a), does this maximize social surplus (Net Payoff of Young + Net Payoff of Old)? c. Suppose Young has a right to party (Old cannot forcibly prevent Young). Old and Young bargain over Young going to party. How much will Old have to offer Young to make him willing to not party?arrow_forwardOne method of solving this problem is through signaling. Signaling is a strategy one uses when they have information. The goal is to use a signal to convince the buyer that the good or service that is being sold is quality and will meet the buyer's wants. Offer an example of a company that uses a signal to help sell its product. What is the signal? What information is the signal trying to convey? Do you think the signal is effective? Why or why not? Does this signal improve market efficiency? Why or why not?arrow_forward

Each firm must consider how safe to make its plant. Extra safety is costly. Safety investments-sprinkler systems, color-coded switches. fire extinguishers-by one firm provide an externality to other firms: That firm's lower incidence of accidents reduces the wage that all firms in the industry must pay. Because each firm bears the full cost of its safety investments but derives only some of the benefits, the firms underinvest in safety. It will be a Nash equilibrium for both firms invest safety if O A. the payoffs for both firms investing increase to $750 and the payoffs for both firms not investing decrease to $50.
