Economic studies typically underestimate incremental changes in consumer goods and design innovations that enhance allocative efficiency and structural dynamics. This paper assesses over 12,000 innovations by female patentees and participants in industrial fairs and prize-granting institutions...

Rankings have become increasingly popular on various markets, e.g. the market for study programs. We analyze their welfare implications. Consumers have to choose between two goods of unknown quality with exogenous presence or absence of an unbiased informative ranking. The existence of the...

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 60-90% of the monthly payment increase. Most of this is driven...

Temporary price reductions (sales) are common for many goods and naturally result in large increase in the quantity sold. We explore whether the data support the hypothesis that these increases are, at least partly, due to dynamic consumer behavior: at low prices consumers stockpile for future...

We show that a straight forward approximation of the distribution of durable goods holdings gives rise to a tractable equilibrium (S,s) model of durable demand. We analyze both competitive and monopoly supply. We show that equilibrium interactions lead to elongated impulse responses in demand,...

Popular wisdom holds that publishers revise college textbooks mainly to kill off the secondary market for used books. While this behavior might be profitable if consumers are myopic, uninformed or have high short-run discount rates (that exceed the publishers'), neoclassical authors have noted...

One important channel through which real interest rates affect aggregate demand is consumer expenditure on durable goods. This paper examines empirically the link between interest rates and consumer durables. Solving for the decision rule relating income and interest rates to consumer demand is...

I examine price markups in monopolisticly-competitive markets that experience fluctuations in demand because the economy experiences cyclical fluctuations in productivity. Markups depend positively on the average income of purchasers in the market. For a nondurable good average income of...
