Dominiak, Adam; Dürsch, Peter; Lefort, Jean-Philippe, 2014, "A dynamic Ellsberg urn experiment [Dataset]", https://doi.org/10.11588/data/10005, heiDATA, V2, UNF:5:6SM6f4NWdacC70zww1ngbA== [fileUNF]
Abstract Many theories of updating under ambiguity assume either dynamic consistency or consequentialism to underpin behaviorally the link between conditional and unconditional preferences. To test the descriptive validity of these rationality concepts, we conduct a dynamic exten...

Kops, Christopher; Pasichnichenko, Illia, 2020, "A Test of Information Aversion", https://doi.org/10.11588/data/G0RNAZ, heiDATA, V1, UNF:6:GkvwqL6qHXH4RRvkp1xJWA== [fileUNF]
The standard Bayesian model implies that information can never have a negative value. We put this implication to the proof. Our paper provides the first test of the value (positive or negative) of information under uncertainty. We show that the ``Bayesian implication'' stands in...

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...

Trautmann, Stefan T.; Van de Kuilen, Gijs, 2014, "Ambiguity attitudes [Supplemental material]", https://doi.org/10.11588/data/10011, heiDATA, V2
The handbook chapter reviews experimental methods to measure ambiguity attitudes, as well as the recent experimental evidence regarding these attitudes. The data file contains background data that form the basis of Table 1 in the chapter.

Trautmann, Stefan T.; König-Kersting, Christian, 2016, "Ambiguity Attitudes in Decisions for Others [Dataset]", https://doi.org/10.11588/data/10084, heiDATA, V2, UNF:5:+nuSVaYwRhcCKiFHfar1iA== [fileUNF]
We probe the pattern of ambiguity aversion for moderate-likelihood gain prospects, and ambiguity seeking for low-likelihood gain prospects, if people make decisions not for themselves but as agents for others. We confirm the pattern both with and without accountability.

Xu, Yilong; Xu, Xiaogeng; Tucker, Steven, 2018, "Ambiguity Attitudes in the Loss Domain: Decisions for Self versus Others [Dataset]", https://doi.org/10.11588/data/MHUGKP, heiDATA, V1, UNF:6:SxDjm/HSLtSILr2x39sg5g== [fileUNF]
We study whether people’s ambiguity attitudes differ when deciding for themselves or for others in the loss domain. We find no differences in ambiguity attitudes between self- and other-regarding decision-making. Our results are consistent with the loss part of the fourfold patte...

Kocher, Martin G.; Lahno, Amrei Marie; Trautmann,Stefan T., 2017, "Ambiguity aversion is not universal [Dataset]", https://doi.org/10.11588/data/BU56YA, heiDATA, V1
Assuming universal ambiguity aversion, an extensive theoretical literature studies how ambiguity can account for market anomalies from the perspective of expected utility-based theories. We provide a systematic experimental assessment of ambiguity attitudes in different likelihoo...

Trautmann, Stefan T.; Kocher, Martin; Pahlke, Julius, 2015, "An Experimental Study of Precautionary Bidding [Dataset]", https://doi.org/10.11588/data/10060, 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...

Trautmann, Stefan T.; Kuilen, Gijs van de, 2014, "Belief Elicitation: A Horse Race among Truth Serums [Dataset]", https://doi.org/10.11588/data/10004, heiDATA, V3, UNF:5:rdLqOxsqtpO3QKanCTJFPw== [fileUNF]
We pit non-incentivized introspection against five revealed preference mechanisms (“truth serums”) in the elicitation of beliefs in a simple two-player game. We measure the additivity, the predictive power for own behaviour, and the accuracy of each method. Beliefs from incentivi...

Schmidt, Robert, 2019, "Capitalizing on the (False) Consensus Effect: Two Tractable Methods to Elicit Private Information [Dataset]", https://doi.org/10.11588/data/7WGSTU, heiDATA, V1, UNF:6:NNk+dDpsSu2ZXVMSVkJtQQ== [fileUNF]
We propose and experimentally test two tractable methods to incentivize the elicitation of private information: Benchmark and Coordination. Both mechanisms capitalize on the false consensus effect, a well-documented phenomenon that follows Bayesian reasoning. That is, individuals...
