The relationship between market structure and advertising has been extensively studied, but has generated sharply opposing theoretical predictions, as well as inconclusive empirical findings, likely due to severe endogeneity concerns. We exploit the 2008 merger of Miller and Coors in the U.S....

We revisit the relationship between competition and price discrimination in the airline industry. Theoretically, we show that, if consumers differ in terms of both their underlying willingness-to-pay and their brand loyalty, competition may increase price differences between some consumers while...

This paper studies the role of imperfect information in explaining price dispersion. We use a new panel dataset on the U.S. retail gasoline industry, and propose a new test of temporal price dispersion to establish the importance of consumer search. We show that price rankings vary significantly...

We examine the scope and value of targeted advertising in the magazine industry. We use data on reader characteristics at individual media, in contrast to previous work that has needed to infer this information from aggregate data. Our results show a strong relationship between subscriber...
