Prof. Dr. Dr. Marlies Ahlert joined Käte Hamburger Kolleg / Centre for Global Cooperation Research as a Senior Fellow. She conducted her research in Research Unit 1 “The (Im)Possibility of Cooperation” from April 2013 to March 2014.

Research Project at the Centre

Cooperation in Negotiations – Theory, Experiments, Case Studies

Marlies Ahlert builds on her previous work on a descriptive bargaining model based on the theory of aspiration adaptation. The aspiration adaptation approach is applied to bilateral one - or multidimensional negotiations. It models how the concession making process develops over the course of a cooperation/negotiation, especially in reference to what the respective opponent is claiming or offering. In this regard, experimental findings on how real actors bargain are used for developing an economic bargaining theory that considers agents to be boundedly rational. While at the Centre, Marlies Ahlert will further refine the aspiration-based bargaining model for realistic applications to complex negotiation processes incorporating many dimensions of interest.
