- Early in August an undergraduate college discovers that it can accommodate a few extra students. Enrolling those additional students would provide a substantial increase in revenue without increasing the operating costs of the college; that is, no new classes would have to be added.

- Your employer, an insurance company, would like to offer theft insurance for renters. The policy would pay the full replacement value of any items that were stolen from the apartment. Some apartments have security alarms installed. Such systems detect a break-in and ring an alarm within the apartment. The insurance company estimates that the probability of a theft in a year is .05 if there is no security system and .01 if there is a security system (there cannot be more than one theft in any year). An apartment with a security system costs the renter an additional $50 per year. Assume that: the dollar loss from a theft is $10,000, the insurance company is risk neutral, and the renter would be willing to pay more than the expected loss to insure against the loss of theft. What is the insurance company's break-even price for a one-year theft insurance policy for an apartment without a security system? Does a renter have an incentive to pay for a security system if he…arrow_forwardYour employer, an insurance company, would like to offer theft insurance for renters.
