We use a dataset for a demographically representative sample of the Dutch population that contains a revealed preference risk attitude measure, as well as detailed information about participants’ religious background, to study three issues. First, we find strong confirmatory evidence that more...

We investigate risk and ambiguity attitudes among Ethiopian farmers in one of the poorest regions of the world. Strong risk aversion and ambiguity aversion were found with the Ethiopian farmers. We compared their attitudes to those of a Western university student sample elicited by the same...

This paper presents an experimental study of common consequence effects in binary choice, willingness-to-pay (WTP) elicitation, and willingness-to-accept (WTA) elicitation. We find strong evidence in favor of the fanning out hypothesis (Machina, Econometrica 50:277–323, <CitationRef CitationID="CR14">1982</CitationRef>) for both WTP and...</citationref>

Auctions often involve goods exhibiting a common knowledge ex-post risk. Precautionary bidding predicts that under expected utility, ex-post risk leads DARA bidders to reduce their bids by more than the appropriate risk premium. Because the degree of riskiness of the good, and bidders risk...

People often need to choose between alternatives with known probabilities (risk) and alternatives with unknown probabilities (ambiguity). Such decisions are characterized by attitudes towards ambiguity, which are distinct from risk attitudes. Most studies of ambiguity attitudes have focused on...

We looked at risk and ambiguity attitudes among Ethiopian peasants in one of the poorest regions of the world and compared their attitudes to a standard Western university student sample elicited by the same decision task. Strong risk aversion and ambiguity aversion were found with the Ethiopian...

This paper experimentally studies the impact of uncertainty about bank and borrower fundamentals on loan repayment. We find that solvent borrowers are more likely to default strategically when stricter disclosure creates common knowledge about bank weakness. Borrowers are also less likely to...

We conduct a laboratory experiment to examine under which circumstances a depositor-run at one bank may lead to a depositor-run at another bank. We implement two-person coordination games which capture the essence of the Diamond-Dybvig (1983) bank-run model. Subjects in the roles of followers...
