Which of the following examples is an adverse-selection problem and which is an incentive problem? Explain why. In each case, give one method that the restaurant might use to reduce the problem. (A) A restaurant decides to offer an all-you-can-eat buffet that is sold for a fixed price. The restaurant discovers that the customers for this buffet are not its usual clientele. Instead, the customers tend to have big appetites. The restaurant loses money on the buffet. (B) A restaurant owner hires a manager who promises to work long hours. When the owner is out of town, the manager goes home early. This action results in lost profits for the firm.
