Predatory pricing--a deliberate strategy of pricing aggressively in order to eliminate competitors--is one of the more contentious areas of antitrust policy and its existence and efficacy are widely debated. The purpose of this paper is to formally characterize predatory pricing in a modern...

We start from an aggregate random coefficients nested logit (RCNL) model to provide a systematic comparison between the tractable logit and nested logit (NL) models with the computationally more complex random coefficients logit (RC) model. We first use simulated data to assess possible...

We investigate how temporary ownership by private equity firms affects industry structure, competition and welfare. Temporary ownership leads to strong investment incentives because equilibrium resale prices are determined partly by buyers' incentives to block rivals from obtaining assets. These...

We study cartel contracts using data on 18 contract clauses of 109 legal Finnish manufacturing cartels. One third of the clauses relate to raising profits; the others deal with instability through incentive compatibility, cartel organization, or external threats. Cartels use three main...

This model describes the working of hub-and-spoke collusion that has been discussed recently by competition policy authorities. We develop a model of tacit collusion between a manufacturer and two retailers, competing a la Rotemberg and Saloner (1986). The best collusive equilibrium between...

This paper reports results from an experiment studying how fines, leniency programs and reward schemes for whistleblowers affect cartel formation and prices. Antitrust without leniency reduces cartel formation, but increases cartel prices: subjects use costly fines as (altruistic) punishments....

Anti-competitive mergers benefit competitors more than the merging firms. We show that such externalities reduce firms' incentives to merge (a hold-up mechanism). Firms delay merger proposals, thereby foregoing valuable profits and hoping other firms will merge instead - a war of attrition. The...

Empirical evidence strongly suggests that R&D increases a firm’s ‘absorptive capacity’ (its ability to absorb spillovers from other firms) as well as contributing directly to profitability. We explore the theoretical implications of this. We specify a general model of the absorptive...

This Paper introduces optimal competition: the best form of competition in an industry that a competition authority can achieve (given the information constraint that it cannot observe firms’ efficiency levels). We show that the optimal competition outcome in an industry becomes more...

We quantify the competitive effects of removing vertical restraints, based on the recent proposals to liberalize the selective and exclusive distribution system in the European car market. We estimate a differentiated products demand system for new cars and specify a model of oligopoly pricing...
