Vanberg, Christoph, 2014, "Why do people keep their promises? An experimental test of two explanations",, heiDATA, V2, UNF:5:LLxs3XkQ6C/SySd6VWVBWQ== [fileUNF]
Numerous psychological and economic experiments have shown that the exchange of promises greatly enhances cooperative behavior in experimental games. This paper seeks to test two theories to explain this effect. The first posits that individuals have a preference for keeping thei...

Dürsch, Peter;Kolb, Albert;Oechssler, Jörg;Schipper, Burkhard C., 2014, "Rage Against the Machines: How Subjects Learn to Play Against Computers [Dataset]",, heiDATA, V3, UNF:5:UE+VbT403TpvbwYdzJeHMQ== [fileUNF]
We use a large-scale internet experiment to explore how subjects learn to play against computers that are programmed to follow one of a number of standard learning algorithms. The learning theories are (unbeknown to subjects) a best response process, fictitious play, imitation, r...

Eichberger, Jürgen;Oechssler, Jörg;Schnedler, Wendelin, 2014, "How do subjects view multiple sources of ambiguity? [Dataset]",, heiDATA, V1, UNF:5:opzxnDkbHOo4fM7i9CoiIw== [fileUNF]
As illustrated by the famous Ellsberg paradox, many subjects prefer to bet on events with known rather than with unknown probabilities, i.e., they are ambiguity averse. In an experiment, we examine subjects’ choices when there is an additional source of ambiguity, namely, when th...

Bauernschuster, Stefan;Dürsch, Peter;Oechssler, Jörg;Vadovic, Radovan, 2014, "Mandatory Sick Pay Provision: A Labor Market Experiment [Dataset]",, heiDATA, V2, UNF:5:QN3j/kE7cRnB9bWCisLgMg== [fileUNF]
The question whether a minimum rate of sick pay should be mandated is much debated. We study the effects of this kind of intervention with student subjects in an experimental laboratory setting rich enough to allow for moral hazard, adverse selection, and crowding out of good int...

Apesteguia, Jose;Huck, Steffen;Oechssler, Jörg;Weidenholzer, Simon, 2014, "Imitation and the Evolution of Walrasian Behavior: Theoretically Fragile but Behaviorally [Dataset]",, heiDATA, V2, UNF:5:9uTZvsy6tiSJe0U8/cdxPw== [fileUNF]
A well-known result by Vega-Redondo (1997) [18] implies that in symmetric Cournot oligopolies, imitation leads to the Walrasian outcome. We show that this result is not robust to the slightest asymmetry in costs, since every outcome where agents choose identical actions will be p...

Huck, Steffen;Normann, Hans-Theo;Oechssler, Jörg, 2014, "Two are Few and Four are Many: Number Effects in Experimental Oligopoly [Dataset]",, heiDATA, V1, UNF:5:ZO79Xsj/X7piQu3p8pQheg== [fileUNF]
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 f...

Apesteguia, Jose;Huck, Jose;Oechssler, Jörg, 2014, "Imitation - Theory and Experimental Evidence [Dataset]",, heiDATA, V1, UNF:5:5pL5x5wCWhIWWBXoTb46LA== [fileUNF]
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 mainly explained by different informational assumptions, and to...

Huck, Steffen;Normann, Hans-Theo;Oechssler, Jörg, 2014, "Does Information about Competitors' Actions Increase or Decrease Competition in Experimental Oligopoly Markets? [Dataset]",, heiDATA, V1
This paper investigates the impact the publication of firm-specific data has on the competitiveness of experimental oligopoly markets. We compare two treatments: in one, firms are informed about their rivals’ actions and profits. In the other, firms are only given aggregate infor...

Huck, Steffen;Normann, Hans-Theo;Oechssler, Jörg, 2014, "Stability of the Cournot Process - Experimental Evidence [Dataset]",, heiDATA, V1
We report results of experiments designed to test the predictions of the best-reply process. In a Cournot oligopoly with four firms, the best-reply process should theoretically explode if demand and cost functions are linear. We find, however, no experimental evidence of such ins...

Huck, Steffen;Normann, Hans-Theo;Oechssler, Jörg, 2014, "Learning in Cournot Oligopoly - An Experiment [Dataset]",, heiDATA, V1
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 results show that some subjects imitate s...
