Real-time search in the laboratory and the market
While widely accepted models of labor market search imply a constant reservation wage policy, the empirical evidence strongly suggests that reservation wages decline in the duration of search. This paper reports the results of the first real-time-search laboratory experiment. The controlled environment that subjects face is stationary, and the payoff-maximizing reservation wage is constant. Nevertheless, subjects' reservation wages decline sharply over time. We investigate two hypotheses to explain this decline: 1) searchers respond to the stock of accruing search costs, and 2) searchers ...

A concise test of rational consumer search
A simple model of time allocation between work and price-search predicts that consumers spend relatively more time searching for better prices for goods of which they consume relatively more. Using scanner data, we confirm empirically that consumers pay lower (higher) prices for goods that they buy more (less) of than other consumers. Our results are conservative, because we compare goods that are defined as narrowly as possible by UPC codes, and provide a lower bound for the savings obtained from bargain hunting.

Paying Too Much? Borrower Sophistication and Overpayment in the US Mortgage Market
Comparing mortgage rates that borrowers obtain to rates that lenders could offer for the same loan, we find that many homeowners significantly overpay for their mortgage, with overpayment varying across borrower types and with market interest rates. Survey data reveal that borrowers’ mortgage knowledge and shopping behavior strongly correlate with the rates they secure. We also document substantial variation in how expensive and profitable lenders are, without any evidence that expensive loans are associated with a better borrower experience. Despite many lenders operating in the US ...
