Imitation - Theory and Experimental Evidence -

Apesteguia, Jose; Huck, Steffen; Oechssler, Jörg - 2005

We introduce a generalized theoretical approach to study imitation and subject it to rigorous experimental testing. In our theoretical analysis we find that the different predictions of previous imitation models are due to different informational assumptions, not to different behavioral rules....

Imitation and the Evolution of Walrasian Behavior: Theoretically Fragile but Behaviorally Robust

Apesteguia, Jose; Huck, Steffen; Oechssler, Jörg; … - 2007

A well-known result by Vega-Redondo implies that in symmetric Cournot oligopoly, imitation leads to the Walrasian outcome where price equals marginal cost. In this paper we show that this result is not robust to the slightest asymmetry in fixed costs. Instead of obtaining the Walrasian outcome...

Imitation and the evolution of Walrasian behavior: theoretically fragile but behaviorally robust

A well-known result by Vega-Redondo (1997) implies that in symmetric Cournot oligopoly, imitation leads to the Walrasian outcome where price equals marginal cost. In this paper, we show that this result is not robust to the slightest asymmetry in fixed costs. Instead of obtaining the Walrasian...

Pure Saddle Points and Symmetric Relative Payoff Games

Duersch, Peter; Oechssler, Jörg; Schipper, Burkhard C. - 2010

It is well known that the rock-paper-scissors game has no pure saddle point. We show that this holds more generally: A symmetric two-player zero-sum game has a pure saddle point if and only if it is not a generalized rock-paper-scissors game. Moreover, we show that every finite symmetric...

Dürsch, Peter; Kolb, Albert; Oechssler, Jörg; … - 2005

number of standard learning algorithms. The learning theories are (unbeknown to subjects) a best response process, fictitious … play, imitation, reinforcement learning, and a trial & error process. We test whether subjects try to influence those … and that all learning algorithms are subject to exploitation with the notable exception of imitation. The experiment was …
