The research at the chair for contract theory and information economics is primarily in the fields of game theoretical modelling of both personnel decisions in companies and the decision of companies in the context of strategic interactions with other companies and costumers.
Regarding personnel decisions within companies, the focus of research is on the aspects of incentive and contract design. Particularly the consideration of psychological findings allows for many new insights e.g. regarding the design of incentive contracts with alternative risk preferences, the design of the working environment with time-inconsistent behaviour or the structuring of the performance appraisal process with cognitive limitations of perception.
Regarding the decisions of companies in the context of strategic interactions on markets the research at the chair for contract theory and information economics is primarily focused on questions regarding competition policy e.g. the effects of a ban of third degree price discrimination on the markets for intermediate goods on firms and consumers.
