We axiomatize preferences that can be represented by a monotonic aggregation of subjective expected utilities generated by a utility function and some set of i.i.d. probability measures over a product state space, S1. For such preferences, we define relevant measures, show that they are treated...

This paper provides a positive theory about the contractual form of procurement contracts under cost uncertainty. However, while the cost of manufacture is uncertain it can be reduced by an amount depending on the extent of effort exerted by the agent. The effort exerted by the agent is not...

This paper analyzes optimal wage contracting assuming agents are not subjective expected utility maximizers but are, instead, ambiguity (or uncertainty) averse decision makers who maximize Choquet expected utility. We show that such agents will choose not to include any indexation coverage in...

This paper surveys some economic applications of the decision theoretic framework pioneered by David Schmeidler. We have organized the discussion around three themes: financial markets, contractual arrangements and game theory. The first section discusses papers that have contributed to a better...

It is widely thought that incomes risks can be shared by trading in financial assets. But financial assets typically carry some risk idiosyncratic to them, hence, disposing incomes risk using financial assets will involve buying into the inherent idiosyncratic risk. However, standard theory...

If agent`s (subjective) beliefs are ambiguous then the beliefs may not be represented by a unique probability distribution in the standard Bayesian fashion but instead by a set of probabilities. Roughly put, an ambiguity averse decision maker evaluates an act by the minimum expected value that...

We define a behavioral concept of relevance in the context of decision making under uncertainty.  We argue that this concept provides a sensible answer to the question "What probabilistic environments do an individuals' preferences reveal as mattering to her decisions?" under a symmetry...

This paper reports the findings of a meta-analysis of 37 papers with 75 results from ultimatum game experiments. We find that on average the proposer offers 40% of the pie to the responder. This share tends is smaller for larger pie sizes and larger when a strategy method is used or when...

Abstract: Using a dataset for a demographically representative sample of the Dutch population, containing a revealed preference risk attitude measure, as well as very detailed information about participants’ religious background, we study three issues raised in previous literature. First, we...

This paper studies the effect of the HIV/AIDS epidemic on saving behaviour. Two important characteristics of HIV result in opposing forces on savings: mortality increases, which reduces savings, and long-term illness risk increases, which enhances savings. We use a two period life-cycle model...
