A methodology is proposed to estimate structural models of product line competition. This methodology enables researchers to estimate demand systems accounting for the endogeneity of the mix of products available in each market, an issue which is typically ignored in the empirical literature. In...

Motivated by recent trends in apps and electronic media, I study the pricing decision of a durable-goods monopolist to derive conditions under which freemium pricing is optimal. Under freemium pricing, the firm charges a price of zero for the durable good but offers optional micro-transactions...

We analyze a sample of fare quotes, collected from the three leading on-line travel agents on fifty large US airline markets. Looking at the lowest fares available, we determine competition between the travel agents ensures the consumer can get a better deal. The travel agents compete more on...

I analyze the extent to which competitors adopt similar pricing strategies. Using an extensive panel data set, I find substantial heterogeneity in the price setting behavior of nearby competitors. The differences in strategy can be explained, in part, by the size of firms and relative...

We investigate the relation between Net Neutrality regulation and Internet fragmentation. We model a two-sided market, where Content Providers (CPs) and consumers interact through Internet Service Providers (ISPs), and CPs sell consumers' attention to advertisers. Under Net Neutrality, a...

This article estimates a model of optimal search where consumers learn the distribution of gasoline prices during their driving trips. Our estimation incorporates traffic information and leverages the ordered search environment to recover parameters of the search and learning process using only...

Despite the empirical relevance of advertising strategies in concentrated markets, the economics literature is largely silent on the effect of persuasive advertising strategies on pricing and market structure and increasing (or decreasing) dominance. We propose a simple model of persuasive...

We introduce a model of oligopoly dynamic pricing where firms with limited capacity face a sales deadline. We establish conditions under which the equilibrium is unique and converges to a system of differential equations. Using unique and comprehensive pricing and bookings data for competing...

The article proposes an evolutionary game theoretical analysis of quality and price competition in oligopoly. Using the notion of a finite population evolutionarily stable strategy (FPESS) defined by Schaffer (1989), the relative payoff maximizing behavior is compared with the absolute payoff...

The theoretical relationship between market structure (number of firms) and conduct (pricing behavior) of the generic drug industry was investigated. The effects of qualitative variables such as therapeutic category, duration of use, popularity, and market entry aggressiveness on the...
