We develop a model of vertical mergers with open auctions upstream, This setting may be appropriate for industries where inputs are procured via auction-like "requests for proposal." For example, Drennan et al (2020) reports that a model of this type was used during the CVS-Aetna merger...

This article addresses developments in the literature on The Rise of Market Power. First, it summarizes research about the result of De Loecker 2020 that the sales-weighted average markup has increased in the United States. Second, it summarizes and evaluates a set of industry studies that...

We provide empirical evidence that automobile manufacturers use cash incentives to offset how gasoline price fluctuations affect the expected fuel expenses of automobile buyers. Regressions based on a database of incentives over 2003 to 2006 suggest that on average, manufacturers offset 40% of...

An important theoretical literature motivates collateral as a mechanism that mitigates adverse selection, credit rationing, and other inefficiencies that arise when borrowers have ex ante private information. There is no clear empirical evidence regarding the central implication of this...

We model competition between two firms in an upstream-downstream relationship. Each firm can pay a sunk cost to enter the other's market. We show that coordination (e.g., through merger) can be anticompetitive, and that such coordination can arise in equilibrium.

We model a “new economy” industry where innovation is sequential and monopoly is persistent but the incumbent turns over periodically. In this setting we analyze the effects of “extraction” (e.g., price discrimination that captures greater surplus) and “extension” (conduct that...

We demonstrate that cost pass-through can be used to inform demand calibration, potentially eliminating the need for data on margins, diversion, or both. We derive the relationship between cost pass-through and consumer demand using a general oligopoly model of Nash–Bertrand competition and...
