Explain the difference between the incentives of the owner of a house and renter of a house to undertake expenditures designed to improve or maintain the house. For example, are renters more likely to replace light bulbs or wall-to-wall carpets when they wear out? When renters spend funds on a new bookcase, is it likely to be built-in or portable? What are the parallels between incentives here and the incentives of Congress when it comes to current expenditures versus capital expenditures?
