Our economists publish research papers, write notes and make presentations on projects we have worked on. Have a look to our publications below:
Competition authorities throughout the EEA employ a variety of methodologies to define local geographic markets in mergers involving grocery retailers. In doing so, however, several authorities neglect the competitive constraint posed by competing stores located outside a given shop’s catchment area. We suggest an accurate, consistent, and resource-efficient approach.
Imperfect competition is not necessarily a curse. It evokes an environment in which firms compete on multiple dimensions to satisfy heterogeneous consumer preferences. This can create a tension between conflicting social objectives. Inevitably, we must decide which of these objectives should guide competition law. In making this decision, we must accept that it is impossible […] Read more
The Lear Competition Note (LCN) discusses the existing literature on the interaction between State aid intervention that incentivizes the investment in decarbonisation technologies and the market-based mechanism relying on the European Union Emission Trading System (ETS). Now in its fourth phase, the EU ETS is often considered the most effective policy to reduce greenhouse gas […] Read more
It is often claimed that rewards for whistleblowers lead to fraudulent reports, but for several US programs this has not been a major problem. We model the interaction between rewards for whistleblowers, sanctions against fraudulent reporting, judicial errors, and standards of proof in the court case on a whistleblower’s allegations and the possible follow-up for […] Read more
“The best way to begin an economic analysis is to ask a relevant question. In a merger analysis the relevant question is: will the post-merger new entity have the ability and the incentive to exert a higher market power? But which analyses are best suited to answer these questions? This note argues that the best […] Read more
Damage actions may reduce leniency programs’ attractiveness for cartel participants if their cooperation with the competition authority increases the chance that the cartel’s victims will sue them. This apparent conflict between public and private antitrust enforcement led to calls for a legal compromise. We show that the conflict is due to the legislation, and a […] Read more
This paper presents a broad retrospective evaluation of mergers and merger decisions in markets dominated by multisided digital platforms. First, we document almost 300 acquisitions carried out by three major tech companies—Amazon, Facebook, and Google—between 2008 and 2018. We cluster target companies on their area of economic activity providing suggestive evidence on the strategies behind […] Read more
