The Individual can also buy partial insurance with i. a $200 deductible, or ii. 75% coinsurance, or iii. Upper limit on coverage, with the limit being $1000. The premium on each partial coverage policy is $450. Provide a ranking of the four types of policies for the individual, in terms of preference if the preference function is given by U(FW) = LN(1+FW), where FW is final wealth of the individual.

FW (no insurance) = Physical assets + cash - Total loss forecast = 2000 + 600 - 400 = $ 2200 [ RANK 1]
FW ( full insurance) = Physical assets + cash - Insurance Premium = 2000 + 600 - 600 = $ 2000 [RANK 2]
FW (partial insurance with $200 deductible) = Physical assets + cash - Insurance Premium (i.e., $450)- Deductible = $1950 [RANK 3]
FW (partial insurance with 75% co-payment) = Physical assets + cash - Insurance Premium (i.e., $450)- copayment ( i.e., 75% of total loss forecast) = 2000 + 600 - 450 - 300 = $1850 [RANK 4]
FW (partial insurance with $ 1000 limit) = Physical assets + cash - Insurance Premium (i.e., $450)- forecast value of expected loss of $ 2000 = 2000 + 600 - 450 - 200 = $1950 [ RANK 3]
Ranks for consumer are juxtaposed above as the utility function is based on LN (natural logarithm) of FW. In other words more the FW, higher the utility.
