(07231) 28-6324Martin Leroch has been Professor of Economics and Ethics at Pforzheim University since fall 2020. Before joining Pforzheim University, he was employed as an economist and consultant at Lademann & Associates GmbH, Hamburg, most recently in a managerial role. One of his core tasks was the preparation of expert witness reports for private damage proceedings, most importantly estimations of damages accruing from violations of competition law.
After completing his diploma in Economics at the Ludwig-Maximilians-University Munich, Martin Leroch received his doctorate degree from the University of Hamburg, where he was later employed as a postdoctoral researcher. His thesis consisted of several papers on institutional economics, as well as law & economics. In 2011, he joined the Institute of Political Science at the Johannes-Gutenberg-University Mainz. Over the years, he held several external lectureships both domestically and abroad (namely in India and Ethiopia), covering various topics, from global economy over microeconomics, game theory to law & economics. Martin Leroch also held a deputy professorship for Economics, especially Microeconomics and Public Economics at the Martin-Luther-University Halle.
Social life is often shaped by formal and informal rules and norms, which are called institutions. On the one hand, they determine the operational framework for economic and other activities, on the other hand, they themselves are shaped by people’s incentives, including economic interests. How this happens and what effects they cause are the core questions of Martin Leroch’s research.
Martin Leroch’s specific projects include, for example, an experimental analysis of the influence of group membership and violence exposure on individuals’ behaviors. Building on qualitative data, he has further developed a formal model by means of which he has analyzed the effects of changes in the legal framework on certain forms of expressive crime. Argumentatively, he has tried to explain why people hold corporations (instead of natural persons) morally responsible. Using statistical methods, he analyses the influence of judicial independence on refugee acceptance rates, together with two co-authors.
In addition, Martin Leroch deals with various questions in the area of competition law, which are of immediate practical relevance. These include questions of causality in the passing-on of cartel damages to third parties and cartel screening.
