A person has a net asset of $1 million, including a $300,000 net equity of a house (market value of the house – mortgage). Specifically, the house has a market value of $600,000 including $400,000 for the structure and $200,000 for the land, and a mortgage of $300,000. The person plans to buy $400,000 fire insurance for full coverage of the house. For simplicity, assume that each year the house has a 1% probability of being totally destroyed by fire and a 99% probability of no damage occurring to the house. The person’s utility for money is approximately proportional to the quartic root of money with U($100,000,000)=1,000 and U($0)=0.
7a. Draw the decision tree for the person’s decision of buying or not buying the insurance.
