Traditional theories of airline pricing maintain that fares monotonically increase as fewer seats remain available on a flight. A fortiori, this implies a monotonically increasing temporal profile of fares. In this paper, we exploit the presence of drops in offered fares over time as an...

We compile a new database of grocery prices in Argentina, with over 9 million observations per day. Our main novel inding is that product prices almost do not vary within stores of a chain (i.e., uniform pricing). We also find that prices do not change significantly with regional conditions or...

In a recent paper Hong and Shum [2006. Using price distributions to estimate search costs. Rand Journal of Economics 37, 257–275] present a structural method to estimate search cost distributions. We extend their approach to the case of oligopoly and present a new maximum likelihood method to...

To provide a more exible workhorse model of temporary price reductions or "sales", this paper presents a substantially generalized "clearinghouse" sales framework. Our framework permits multiple dimensions of firm heterogeneity, and views firms as competing directly in utility rather than...

Prices for the same flight change substantially depending on the time of purchase. This paper uses a unique dataset with round-the-clock posted fares to document significant within-day price variation. Labeling time-variation as discriminatory is difficult because the cost of an unsold airline...
