This paper analyzes the behavior of the Argentine hamburger market during the period 2013-2018, to see if an important merger that occurred by the end of 2015 (the BRF/MRP merger) had any discernable market-power or efficiency effects. To do this, we run an econometric demand-and-supply model,...

Unlike most retrospective merger studies that only focus on price effects, we also estimate the impact of a merger on product variety. We use an original dataset on Dutch supermarkets to assess the effect of a merger that was conditionally approved by the Dutch Competition Authority (ACM) on...

In this paper, we offer a hybrid approach to merger simulation in which we allow rather extensive pre-testing to suggest the ‘correct', or most desirable, form for the underlying demand curves. Our application is the merger between the large mobile telephone companies Cingular and AT&T...

Divestitures have received little attention in ex-post evaluations of mergers. In partial remedy we simulate the effects of the Carlsberg-Pripps merger in the Swedish beer market and compare the predicted outcomes with those observed ex-post. There are no important price increases following the...

Standard discrete choice models used to evaluate mergers assume that different product varieties are substitutes. However, legal defences in some recent high-profile mergers rested on demand complementarity (e.g., GE/Honeywell). Since complements tend to be priced lower by a monopolist than by a...

We study an infinitely-repeated game of oligopolistic price leadership in which one firm, the leader, proposes a supermarkup over Bertrand prices to a coalition of rivals. We estimate the model with aggregate scanner data on the beer industry and find the supermarkup accounts for 6% of price....

We study the effects of merger on firm entry, product variety and prices in the retail craft beer market in California. We develop a new method to estimate multiple-discrete choice models in order to recover fixed costs. The method is based on bounds of conditional choice probabilities and does...

We study the effect of a merger between two Dutch supermarket chains to assess its effect on the depth as well as composition of assortment. We adopt a difference-in-differences strategy that exploits local variation in the merger’s effects, controlling for selection on observables through a...

In this paper we empirically analyse two counterfactual situations facing an antitrust authority following the merger of two of the largest international cigarette companies. First we estimate a random coeffi cients model of the demand for cigarettes. The implied elasticity of demand for smoking...
