Research Workshop on "Contests and the Economics of Conflicts"
Date: 03.- 04. March 2023
Instructor: Dr. Marco Serena (Max Planck Institute for Tax Law and Public Finance)
- Contests and conflicts
- Tullock contests
- All-pay auctions
- Applications of contests
The world has experienced hundreds of armed conflicts since the end of the Second World War. Armed conflicts are important contributors to poverty and underdevelopment. In recent decades, conflicts have increasingly become of interest to economists. In this course, we aim to introduce students to the economics of conflicts and related literature. Conflicts are economic, social, and political problems where agents exert costly efforts while competing over a certain resource.
The workshop provides a survey of the economic literature on the theory of conflicts and contests, starting from some of the earliest models. In addition, the workshop discusses current research directions and some recent papers that use contest models to address applied questions. The main goal of the workshop is to make students familiar with the two basic workhorse models used by researchers to model contests: namely, Tullock contests or all-pay auctions tools.
Prior knowledge of game theory is helpful.
This workshop is open for advanced masters students and PhD candidates. If you would like to participate, please send a short email describing your motivation, together with your CV to naira.kotb(at)uni-bamberg.de before 20.02.2023. You will be notified of your acceptance.
The course will be held in a hybrid-mode. Upon acceptance, participants must make their own travel arrangements for their stay in Bamberg, if the wish to participate in the workshop in person. No financial support is available.
About the Speaker:
Marco Serena is a senior researcher at the Max Planck Institute for Tax Law and Public Finance in Munich and has a Ph.D. in Economics from the University Carlos III of Madrid. A large part of Marco's research focuses on the theory of contests. He uses game theory to address applied questions in settings that can be modeled as contests. Examples range from workers competing for promotions or bonuses, to researchers competing for patents or grants, to politicians and parties running for office.
