Vanberg, Christoph, 2016, "Who never tells a lie? [Data set and Programs]",, heiDATA, V1
I experimentally investigate the hypothesis that many people avoid lying even in a situation where doing so would result in a Pareto improvement. Replicating (Erat and Gneezy, Management Science 58, 723-733, 2012), I find that a significant fraction of subjects tell the truth in...

Roth, Benjamin;Trautmann, Stefan T.;Voskort, Andrea, 2016, "The role of personal interaction in the assessment of risk attitudes [Dataset]",, heiDATA, V1
Many decisions under uncertainty are delegated to professionals, such as financial advisors or medical doctors, requiring them to assess the risk attitudes of their clients or patients. To gain a better under- standing of the potential factors influencing risk attitude assessment...

Oechssler, Jörg;Roomets, Alex;Roth, Stefan, 2016, "From imitation to collusion: a replication [Dataset]",, 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...

Trautmann, Stefan T.;Brown, Martin;Vlahu, Razvan, 2016, "Understanding Bank-Run Contagion [Dataset]",, heiDATA, V1, UNF:5:KUriC0VYM6pSi7sO2HjL/g== [fileUNF]
We study experimental coordination games to examine through which transmission channels, and under which information conditions, a panic-based depositor-run at one bank may trigger a panic-based depositor-run at another bank. We find that withdrawals at one bank trigger withdrawa...

Diederich, Johannes;Goeschl, Timo;Waichman, Israel, 2016, "Group Size and the (In)Efficiency of Pure Public Good Provision [Dataset]",, heiDATA, V1, UNF:5:kp1aULj0nca125TUHszBUg== [fileUNF]
Are larger groups better at cooperation than smaller groups? This paper investigates, under controlled conditions, the presence and direction of a possible group size effect in pure public good provision by large heterogeneous groups. Employing subjects drawn from the general pop...

Kettner, Sara Elisa;Waichman, Israel, 2016, "Old Age and Prosocial Behavior: Social Preferences or Experimental Confounds? [Dataset]",, heiDATA, V1
Experimental and field evidence indicate a positive link between social preferences and age, most strikingly between the elderly and young adults. However, it is possible that the seemingly positive link between age and preferences stems from confounds in experimental procedure....

Pollmann, Monique;Potters, Jan;Trautmann, Stefan T., 2016, "Risk taking by agents: The role of ex-ante and ex-post accountability [Dataset]",, heiDATA, V1, UNF:5:xAMEsbLcHACMf16SEb4syQ== [fileUNF]
We study the role of accountability in situations where an agent makes risky decisions for a principal. We observe that in the absence of accountability, agents choose less risk averse investments for the principal than investors who invest for their own account. Accountability m...

Trautmann, Stefan T.;Kocher, Martin;Pahlke, Julius, 2015, "An Experimental Study of Precautionary Bidding [Dataset]",, heiDATA, V2, UNF:5:RnlzAG0nN9/oXQdIQt8fdA== [fileUNF]
Auctions often involve goods exhibiting a common-knowledge ex-post risk. In such auctions, precautionary bidding predicts that under expected utility, DARA bidders reduce their bids by more than the appropriate risk premium. Because the degree of riskiness of an auctioned good an...

Oechssler, Jörg;Roomets, Alex, 2015, "A Test of Mechanical Ambiguity [Dataset]",, 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...

Günther, Christina;Arslan Ekinci, Neslihan;Schwieren, Christiane;Strobel, Martin, 2015, "Women can´t jump?—An experiment on competitive attitudes and stereotype threat [Dataset]",, heiDATA, V2, UNF:5:MFh9Pa5Rh/urnBELIzJ4uA== [fileUNF]
Gneezy et al. (2003) offer a partial explanation for the wage gap between men and women. In an experiment they found that women react less to competitive incentives. The task they used in their experiment can however be considered a male task. We replicate the experiment and exte...
