Quantity surcharges occur when retailers carry a product in two sizes and offer a promotion on the small size: the large size then costs more per unit than the small one. When quantity surcharges occur, sales of the large size decline only slightly even though the same quantity can be purchased for less. We document this behavior in two data sets and four product categories. It is consistent with the notion of passive shoppers found in the industrial organization literature and the notion of rational inattention in macroeconomics. We discuss implications for consumer decision making, demand estimation, and firm pricing.

Concert tickets can be sold at the same price or at different prices that reflect different seating categories. Price discrimination generates about 5% greater revenues than single-price ticketing. The return to price discrimination is higher in markets with greater demand heterogeneity, as predicted by price discrimination theory. The return to an increase from three to four concert seat categories is roughly half that of an increase from one to two.

Results from the incentive literature suggest that performance measures are often distorted, eliciting dysfunctional and unintended responses. The existence of these responses, however, is difficult to demonstrate in practice because this behavior is typically hidden from the researcher. We present a simple model showing that one can test for the existence of distortions by estimating the change in the association between a performance measure and the true goal of the organization with the measure's introduction. Using data from a public-sector organization, we find evidence consistent with the existence of distortions. We draw implications for the selection of performance measures.
