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... |

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... |

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... |
Dürsch, Peter; Kolb, Albert; Oechssler, Jörg; Schipper, Burkhard C., 2014, "Rage Against the Machines: How Subjects Learn to Play Against Computers [Dataset]", https://doi.org/10.11588/data/10024, 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... |

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... |

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... |
