Working Paper Series in Economics

The Working Paper Series in Economics at the University of Cologne functioned as a platform for the dissemination of original scientific research across all fields of economics and related disciplines, with a particular emphasis on applied microeconomics and behavioral economics, until the series was brought to a close in spring 2026. An overview of the papers published during its period of activity remains available here.

Over the course of its existence, the Working Paper Series featured numerous widely recognized and highly cited contributions, including, for example, Ockenfels and Selten (2005), Impulse Balance Equilibrium and Feedback in First Price Auctions; Greiner (2005), The Online Recruitment System ORSEE 2.0 - A Guide for the Organization of Experiments in Economics; Bolton et al. (2003), How Effective are Electronic Reputation Mechanisms? An Experimental Investigation.

The series continues to be accessible via RePEc.

With the conclusion of the series in spring 2026, the submission of new working papers is no longer possible.
