    The Evolution of "Theories of Harm" in EU Merger Control

    We discuss the main theories of harm in EU merger control and their evolution since the 1990s. We present stylized facts and trends using data extracted from EU merger decisions by natural language processing tools. EU merger policy has adapted over time, both in terms of legislation and theories of harm, as well as in terms of the investigative tools and evidence used. The introduction of the new ...

    Spatial Competition and Pass-through of Fuel Taxes: Evidence from a Quasi-natural Experiment in Germany

    This paper analyses the pass-through rates and their determinants of the temporary German fuel discount in 2022 at its start and its termination. Based on a unique dataset of fuel station characteristics and prices, we employ a Regression Discontinuity in Time (RDiT) methodology to estimate heterogeneous pass-through rates. Our main contribution is to identify the impact of horizontal and vertical ...

    Merger Remedies and Bargaining Power in the Coffee Market

    This paper analyzes a merger of large manufacturers with divestiture in the French coffee market. In contrast to previous approaches used to study the effects of upstream divestitures on prices and welfare, we model the vertical market structure. First, our results show that the standard policy recommendation to require divestiture to small recipient firms may not hold when asymmetric bargaining power ...

    BigTech and Start-Ups: Multi-Product Mergers and Innovation

    The acquisitions of startups by Google, Amazon, Meta, Amazon and Microsoft have steadily increased over the past years and have become more diversified. The current discussion about strategic motives for such acquisitions is vivid – especially in light of present concerns about the market power of gatekeepers, faster technological advances and digitalization. The principal question remains whether...

    Heterogeneous Sourcing, CO2 Emissions and Trade

    International trade separates the location where emissions occur (production) and where they are ultimately consumed. Thus, a substantial share of emissions is embodied in international trade. Moreover, firms within narrowly defined industries differ in their emission intensity. However, most firm-level studies only consider the direct emissions released during the production process. In this...

    How Divestitures Affect Bargaining Power

    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...

    What is the Right Geographic Market Definition?

    What is the “right” geographic definition of relevant markets? We study how unexpected and exogenous increases in excise duties in petroleum products were passed-through to retail prices in the Athens region and examine how the degree of the pass-through varies across different geographic relevant markets. Using various definitions of the relevant geographic market, we find that the most...

    When Competition is not Desired: the Case of Antibiotic Prescribing

    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...
