In 2020, Berlin introduced a rigorous rent-control policy responding to soaring prices by capping rents: the Mietendeckel (rent freeze). The German Constitutional Court revoked the policy only one year later. Although successful in lowering rents during its duration, the consequences for Berlin’s rental market and close-by markets are per se not clear. This article evaluates the short-term causal supply-side ...

This paper studies how bargaining power is affected by merger and divestiture policies. I provide a new empirical framework to compute bounds on brand-level bargaining weights using widely available sales data. Next, I exploit the variation in brand ownership caused by a large merger, cleared conditional on divestiture, in the U.S. deodorant market, to quantify the extent to which divestitures...

High growth firms (HGFs) are important for job creation and considered to be precursors of economic growth. We investigate how product- and labor-market regulations, as well as the quality of regional governments that implement these regulations, affect HGF development across European regions. Using data from Eurostat, OECD, WEF, and Gothenburg University, we show that both regulatory stringency and ...

This paper empirically analyses the impact of government ownership on competition in monopoly and duopoly markets. We use the European Airline Industry as a laboratory. In our empirical strategy we exploit two sources of exogenous variations that allow us to cleanly filter out the effect of government ownership on the likelihood of exit. First, we study government ownership that was triggered by a...

Antibiotics are effective in treating bacterial infections. However, the excessive usage of antibiotics leads to the development of antibiotic resistant bacteria, which significantly reduces their effectiveness. Current strategies to address antibiotic resistance mainly target primary care physicians, who serve as the gatekeepers of antibiotic prescriptions in many countries. Therefore, it is...

This paper sheds new light on the role of communication for cartel formation. Using machine learning to evaluate free-form chat communication among firms in a laboratory experiment, we identify typical communication patterns for both explicit cartel formation and indirect attempts to collude tacitly. We document that firms are less likely to communicate explicitly about price fixing and more likely ...

Research Project
The main purpose of the project is to put together a comprehensive database including qualitative and quantitative information from past merger cases, which would enable DG Competition to produce statistical reports which could serve as an input to DG Competition's decision making practice in relation to EU merger control, both for operational and for policy purposes.
