This paper investigates how privacy regulation affects the structure of online markets. We provide a simple theoretical model capturing the basic trade-off between the degree of privacy intrusion and the informativeness of advertising. We derive empirically testable hypotheses regarding a...

We propose a dynamic direct mailing response model with competitive effects, where purchase and promotion history are incorporated. We then map the dynamic competitive interactions amongst the firms sending the mailings. We investigate the short- and long-run impact of a direct mailing on the...

The Australian Parliament has passed legislation compelling tobacco products to be sold in ?plain packaging?. This paper reviews this legislation and its likely effects on prices, market structure in the tobacco industry and on smoking behaviour. Industry changes following two previous sets of...

We extend the theory of advertising as a quality signal, using a model where an entrant can choose to advertise by comparing its product to that of an established incumbent. Comparative advertising, comparing quality of one’s own product to that of a rival’s, empowers the latter to file for...

The advertising efforts in social networks grow every year. Since their appearance in the late 1990s Social Network Web Sites were considered as a uniform group. The only differentiation factors were the number of users and the amount of traffic passed through the site. This paper classifies the...

This paper analyses the competitive effects of informative advertising. The seminal work by Grossman and Shapiro (1984) show that informative advertising results in lower prices and that firms may benefit from advertising restrictions. A crucial assumption in their model is that captive...

Presidential candidates purchase advertising based on each state’s potential to tip the election. The structure of the Electoral College concentrates spending in battleground states, such that a majority of voters are ignored. We estimate an equilibrium model of multimarket advertising...

Longstanding state regulations restrict car manufacturers from terminating relationships with dealers, creating differences in retail competition across brands and markets. I use this variation to identify the causal effect of dealer competition on dealer and manufacturer advertising. I find...

We study the strategic interaction between a new good producer and a remanufacturer who use advertising campaigns to compete for a dominant share of the market for a certain good. Each firm chooses one of three possible strategies for running its advertising campaign. The two rival firms care...

This paper develops a framework to systematically study how changes in market conditions affect the equilibrium inequality between heterogeneous agents. By stating our setting as a "competition for market shares", we can derive inequality predictions for vastly different competition models. This...
