Oechssler, Jörg; Roomets, Alex, 2020, "Savage vs. Anscombe-Aumann: an experimental investigation of ambiguity frameworks [Dataset]", https://doi.org/10.11588/data/RTQIUG, heiDATA, V1, UNF:6:znXzfO0UeSWMUd6rxjZvVw== [fileUNF]
The Savage and the Anscombe–Aumann frameworks are the two most popular approaches used when modeling ambiguity. The former is more flexible, but the latter is often preferred for its simplicity. We conduct an experiment where subjects place bets on the joint outcome of an ambiguo... |

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... |

Oechssler, Jörg; Roomets, Alex, 2015, "A Test of Mechanical Ambiguity [Dataset]", https://doi.org/10.11588/data/10059, heiDATA, V1, UNF:5:0TQJ35gJjj9nUWl9FiZstA== [fileUNF]
We implement an experiment to elicit subjects’ ambiguity attitudes in the spirit of Ellsberg's three-color urn. The procedure includes three design elements that (together) have not been featured in similar experiments: Strict ambiguity preferences, a single decision, and a mecha... |
