ABSTRACT Using loan‐level data on millions of used‐car transactions across hundreds of lenders, we study the consumer response to exogenous variation in credit terms. Borrowers offered shorter maturity decrease expenditures enough to offset 60% to 90% of the monthly payment increase. Most of this is driven by shifting toward lower‐quality cars, but affected borrowers offset 20% to 30% of a monthly payment shock by negotiating lower prices for equivalent cars. Our results suggest that durable goods prices adjust to reflect credit terms even at the individual level, with one year of additional loan maturity increasing a car's price by 2.8%.

We give two characterizations of Pareto optimality via “near” weighted utilitarian welfare maximization. One characterization sequentially maximizes utilitarian welfare functions using a finite sequence of nonnegative and eventually positive welfare weights. The other maximizes a utilitarian welfare function with a certain class of positive hyperreal weights. The social welfare ordering represented by these “near” weighted utilitarian welfare criteria is characterized by the standard axioms for weighted utilitarianism under a suitable weakening of the continuity axiom.
