Oechssler, Joerg; Roomets, Alex - 2023

Two partners try to dissolve a partnership that owns an asset of ambiguous value, where the value is determined ex post by a draw from an Ellsberg urn. In a within-subject experiment, subjects make decisions in three different bargaining mechanisms: unstructured bargaining, the Texas shoot-out,...

Through trial & error to collusion : the discrete case

Huck, Steffen; Normann, Hans-Theo; Oechssler, Joerg - 2000

In this note we study a very simple trial & error learning process in the context of a Cournot oligopoly. Without any knowledge of the payoff functions players increase, respectively decrease, their quantity by one unit as long as this leads to higher profits. We show that despite the absence of...

On the dynamic foundation of evolutionary stability in continuous models

Oechssler, Joerg; Riedel, Frank - 2000

We show in this paper that none of the existing static evolutionary stability concepts (ESS, CSS, uninvadability, NIS …) is sufficient to guarantee dynamic stability in the weak topology with respect to standard evolutionary dynamics if the …. Evolutionary robustness ensures dynamic stability for replicator dynamics in doubly symmetric games. …

Cooperation as a result of learning with aspiration levels

Oechssler, Joerg - 2001

It is shown that a win-stay, lose-hift behavior rule with endogenous aspiration levels yields cooperation in a certain class of games. The aspiration level in each round equals the current population average. The class of games includes the prisoner's dilemma and Cournot oligopoly and thus...

Can you guess the game you're playing?

Oechssler, Joerg; Schipper, Burkhard - 2000

Recently there has been much theoretical and experimental work on learning in games. However, learning usually means learning about the strategic behavior of opponents rather than learning about the game as such. In contrast, here we report on an experiment designed to test whether players learn...

Two are few and four are many : number effects in experimental oligopolies

Huck, Steffen; Normann, Hans-Theo; Oechssler, Joerg - 2001

In this paper we investigate how the competitiveness of Cournot markets varies with the number of firms in an industry. We review previous Cournot experiments in the literature. Additionally, we conduct a new series of experiments studying oligopolies with two, three, four, and five firms in a...
