e. (4 minutes) Is the highest price that Peter would be willing to pay for this policy smaller, equal to, or greater than the actuarially fair price? Justify. The actuarially fair price is 2%×(750,000
240,000)=10,200. This is lower than the highest price Peter would pay. This is because Peter is risk averse and, as we have seen, risk averse individuals are willing to pay an amount lower than the actuarially fair price to buy full insurance when there is only the option of either full coverage on no coverage at all. f. (4 minutes) Now suppose the insurance company allows Peter to buy as many insurance policies as he wants but charges a positive load in each policy. Should he fully insure? Justify. No. By Mossin’s theorem he should not fully insure when each policy has a positive load.
