We provide a framework for empirical analysis of negotiated-price markets. Using mortgage market data and a search and negotiation model, we characterize the welfare impact of search frictions and quantify the role of search costs and brand loyalty for market power. Search frictions reduce...

This paper develops a model of successive oligopolies with endogenous market entry, allowing for varying degrees of product differentiation and entry costs in both markets. Our analysis shows that the downstream conditions dominate the overall profitability of the two-tier structure while the...

Concerns about anti-competitive effects of proprietary data collection have motivated recent European data portability laws. We investigate such concerns and search for evidence of direct benefits of data collection in the context of Pay How You Drive (PHYD) auto insurance, which offers tailored...

This paper explores, both theoretically and empirically, the impact of granting antitrust immunity (ATI) to airline alliances in a novel and realistic framework characterized by vertically-differentiated air services. Our theoretical model suggests that non-ATI alliances produce an up-market...

We provide an extensive and general investigation of the effects on industryperformance - profits, social welfare and price-cost margins - of exogenously changing the number of firms in Cournot markets. This includes an in-depth exploration of the well-known trade-off between competition and...

We set up a stylized oligopoly model of uncertain product innovation to analyze the effects of a merger on innovation incentives and on consumer surplus. The model incorporates two competitive channels for merger effects: the "price coordination" channel and the internalization of the...

This paper investigates how the formation of larger buyers affects a supplier's profits and, by doing so, his incentives to undertake non-contractible activities. We first identify two channels of buyer power, which allows larger buyers to obtain discounts. We subsequently examine the effects of...

Regulators are responding to growing platform power with curbs on platforms' potentially biased exercise of power, creating urgent needs for both a workable definition of platform bias and ways to detect and measure it. We develop a simple equilibrium framework in which consumers choose among...
