We formulate two empirical tests for collusive behavior based on the theoretical insights of Werden and Froeb [1994] and Athey, Bagwell, and Sanchirico [2004]. The first predicts that colluding firms will reduce pair-wise differences in prices within a market if demand satisfies certain...

Newspapers have been experiencing declining circulation figures and diminishing advertising revenues for several years - both effects might pose a threat to the continuing existence of (print) newspapers. In an earlier paper, Lindstädt & Budzinski (2011) argued from a theoretical viewpoint that...

We study a consumer non-sequential search oligopoly model with search cost heterogeneity. We first prove that an equilibrium in mixed strategies always exists. We then examine the nonparametric identification and estimation of the costs of search. We find that the sequence of points on the...

In many industries, firms usually have two choices when expanding into new markets: They can either build a new plant (greenfield entry) or they can acquire an existing incumbent. In the U.S. cement industry, the comparative advantage (e.g., TFP or size) of entrants versus incumbents and...

We examine the effect of exchange-rate misalignments on competition in the market for large commercial aircraft. This market is a duopoly where players compete in dollar-denominated prices while one of them, Airbus, incurs costs mostly in euros. We construct and calibrate a simulation model to...
