Workshop on Issues in Dynamic Decision Theory


General Description

Time: July 6 – 8, 2023

Place: Bischofsvilla, University of Konstanz

Abstract: The workshop will be organized by the Reinhart-Koselleck project “Reflexive Decision and Game Theory” of Wolfgang Spohn at the University of Konstanz. Its decision-theoretic part is particularly concerned with dynamic choice. Which is hence the topic of the first workshop of this project.

Dynamic choice has indeed become an important topic within the theory of rational choice (decision theory). But it has two different facets. The topic originated in economics from the problem of (endogenous) preference change. Dynamic consistency was then considered to be a central desideratum, leading to theories of sophisticated choice satisfying this desideratum. Since McClennen’s important book in 1990, a different rich discussion has evolved in which dynamic consistency is rather used as a test criterion for various decision rules in a dynamic setting. The former motivation was no longer in the center. Hence, the aim of the workshop is to bring together these two strands of the discussion and to promote an exchange between them. A further aim is to introduce the so-called reflexive perspective which is pursued within the project.
