The effectiveness of public sponsored training revisited: The importance of data and methodological choices

Biewen, Martin; Fitzenberger, Bernd; Osikominu, Aderonke; … - 2012

As the first, substantive contribution, this paper revisits the effectiveness of two widely used public sponsored training programs, the first one focusing on intensive occupational training and the second one on short-term activation and job entry. We use an exceptionally rich administrative...

Nonparametric learning rules from bandit experiments: The eyes have it!

Hu, Yingyao; Kayaba, Yutaka; Shum, Matt - 2010

How do people learn? We assess, in a distribution-free manner, subjects' learning and choice rules in dynamic two …-armed bandit (probabilistic reversal learning) experiments. To aid in identification and estimation, we use auxiliary measures of … subjects' beliefs, in the form of their eye-movements during the experiment. Our estimated choice probabilities and learning …

Once beaten, never again: Imitation in two-player potential games

Duersch, Peter; Oechssler, Joerg; Schipper, Burkhard C. - 2011

We show that in symmetric two-player exact potential games, the simple decision rule imitate-if-better cannot be beaten by any strategy in a repeated game by more than the maximal payoff difference of the one-period game. Our results apply to many interesting games including examples like 2x2...

Unbeatable imitation

Duersch, Peter; Oechssler, Joerg; Schipper, Burkhard C. - 2012

We show that for many classes of symmetric two-player games, the simple decision rule 'imitate-if-better' can hardly be beaten by any strategy. We provide necessary and sufficient conditions for imitation to be unbeatable in the sense that there is no strategy that can exploit imitation as a...

When is tit-for-tat unbeatable?

Duersch, Peter; Oechssler, Joerg; Schipper, Burkhard C. - 2013

We characterize the class of symmetric two-player games in which tit-for-tat cannot be beaten even by very sophisticated opponents in a repeated game. It turns out to be the class of exact potential games. More generally, there is a class of simple imitation rules that includes tit-for-tat but...

Rage Against the Machines: How Subjects Learn to Play Against Computers

Duersch, Peter; Kolb, Albert; Oechssler, Joerg; … - EconWPA - 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 …

Through Trial & Error to Collusion

Huck, Steffen; Normann, Hans-Theo; Oechssler, Joerg - EconWPA - 1998

In this note we study a very simple trial & error learning process in the context of a Cournot oligopoly. Without any …

Learning in Cournot Oligopoly - An Experiment

Huck, Steffen; Normann, Hans-Theo; Oechssler, Joerg - EconWPA - 1997

This experiment was designed to test various learning theories in the context of a Cournot oligopoly. We derive … theoretical predictions for the learning theories and test these predictions by varying the information given to subjects. The …
