Buckert, Magdalena; Oechssler, Jörg; Schwieren, Christiane, 2017, "Imitation under stress [Dataset]", https://doi.org/10.11588/data/VYCCZI, heiDATA, V1, UNF:6:MAZqxVN4vzEoCVKBRyl1KQ== [fileUNF]
Imitation has been shown to be an important heuristic, in particular in relatively complex environments. In this experiment we test whether subjects are more likely to use imitation if they are under time pressure or distracted. Subjects play a repeated Cournot oligopoly. Treatme...

Apesteguia, Jose; Huck, Steffen; Oechssler, Jörg; Weidenholzer, Elke; Weidenholzer, Simon, 2018, "Imitation of Peers in Children and Adults [Dataset]", https://doi.org/10.11588/data/HFTMST, heiDATA, V1, UNF:6:QDuPhtFcF3CPULh+tQIpJQ== [fileUNF]
Imitation of the successful choices of others is a simple and superficially attractive learning rule. It has been shown to be an important driving force for the strategic behavior of (young) adults. In this study we examine whether imitation is prevalent in the behavior of childr...

Apesteguia, Jose; Huck, Steffen; Oechssler, Jörg; Weidenholzer, Simon, 2014, "Imitation and the Evolution of Walrasian Behavior: Theoretically Fragile but Behaviorally [Dataset]", https://doi.org/10.11588/data/10021, 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...

Apesteguia, Jose; Huck, Jose; Oechssler, Jörg, 2014, "Imitation - Theory and Experimental Evidence [Dataset]", https://doi.org/10.11588/data/10019, 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...

Eichberger, Jürgen; Oechssler, Jörg; Schnedler, Wendelin, 2014, "How do subjects view multiple sources of ambiguity? [Dataset]", https://doi.org/10.11588/data/10023, 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...

Nikiforakis, Nikos; Oechssler, Jörg; Shah, Anwar, 2014, "Hierarchy, Coercion, and Exploitation: An Experimental Analysis [Dataset]", https://doi.org/10.11588/data/10015, heiDATA, V3, UNF:5:Vep1OzKyX8y7uU4Zs/av/g== [fileUNF]
The power to coerce workers is important for the efficient operation of hierarchically structured organizations. However, this power can also be used by managers to exploit their subordinates for their own benefit. We examine the relationship between the power to coerce and explo...

Oechssler, Jörg; Rau, Hannes; Roomets, Alex, 2019, "Hedging, ambiguity, and the reversal of order axiom [Dataset]", https://doi.org/10.11588/data/1XDKHZ, heiDATA, V1, UNF:6:c8rHrHnmCxS3BC4O6euGVQ== [fileUNF]
We ran experiments that gave subjects a straight-forward and simple opportunity to hedge away ambiguity in an Ellsberg-style experiment. Subjects had to make bets on the combined outcomes of a fair coin and a draw from an ambiguous urn. By modifying the timing of the draw, coin f...

Oechssler, Jörg; Roomets, Alex; Roth, Stefan, 2016, "From imitation to collusion: a replication [Dataset]", https://doi.org/10.11588/data/10075, heiDATA, V2, UNF:5:qSzzvlOu2rl8/AR8TIBEEQ== [fileUNF]
In oligopoly, imitating the most successful competitor yields very competitive outcomes. This theoretical prediction has been confirmed experimentally by a number of studies. A recent paper by Friedman et al. (J Econ Theory 155:185–205, 2015) qualifies those results in an interes...

Huck, Steffen; Normann, Hans-Theo; Oechssler, Jörg, 2014, "Does Information about Competitors' Actions Increase or Decrease Competition in Experimental Oligopoly Markets? [Dataset]", https://doi.org/10.11588/data/10020, 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...

Copy trading allows traders in social networks to receive information on the success of other agents in financial markets and to directly copy their trades. Internet platforms like eToro, ZuluTrade, and Tradeo have attracted millions of users in recent years. The present paper st...
