This paper develops a way to estimate fixed-cost efficiencies from mergers. The estimates might be used to assess the total welfare impact of retrospective and counterfactual mergers. The procedure uses a structural model in which companies play a dynamic game with endogenous mergers and...

This paper studies mergers in two-sided markets by estimating a structural supply-and-demand model using data from the 1996-2006 merger wave in U.S. radio. It makes two main contributions. First, it identifies the conflicting incentives of merged firms to exercise market power on both sides of...

This paper explores the application of oblivious equilibrium to concentrated industries. We define an extended notion of oblivious equilibrium that we call partially oblivious equilibrium (POE) that allows for there to be a set of "dominant firms'', whose firm states are always monitored by...

The paper documents the causal impact of transaction price on a subsequent product review submitted by the customer. The evidence is obtained using a Large Scale Randomized Field Experiment which introduced a random exploratory component into nightly rates of hundreds of short-term rentals....

The paper provides evidence of the effectiveness of massively scalable automated SMS business training. The training has negligible marginal costs and requires only basic cell phone coverage for enrollment. We conducted a large-scale Randomized Control Trial in which we randomly manipulated the...

Dynamic pricing is a common tool to maximize sales in markets for perishable goods with limited capacity and stochastic demand. We look at the relationship between dynamic pricing and oligopolistic competition in the airline industry. For this purpose, we estimate the dynamic oligopoly model of...
