Experimental research on decision making under risk has until now always employed choice data in order to evaluate the empirical performance of expected utility and the alternative nonexpected utility theories. The present paper performs a similar analysis which relies on pricing data instead of...

The present article examines the question whether or not different types of firms tend to protect their innovations with varying mechanisms. Against the background of the Expected-Utility Theory (EU-Theory), firms are differentiated by their size, technological field and their degree of...

In this paper we analyze a large sample of individual responses to six lottery questions. Wederive a simultaneous estimate of risk aversion ? and the time preference discount rate ? perindividual. This can be done because the consumption of a large prize is smoothed over a largertime period. It...

We specify a stochastic economy-climate model, adapting Nordhaus' deterministic economy-climate model by allowing for Weitzman-type stochasticity. We show that, under expected power utility, the model is fragile to heavy-tailed distributional assumptions and we derive necessary and sufficient...

One possible conclusion from recent experimental research on decision making under risk is that observed behaviour can be reasonable accommodated by expected utility plus an error term. This conclusion implies that the violation rate of expected utility should decrease if errors are excluded....

According to the harmonic sequence paradox (Blavatskyy 2006), an expected utility decision maker's willingness-to-pay for a gamble whose expected payoffs evolve according to the harmonic series is finite if and only if his marginal utility of additional income becomes zero for rather low payoff...

Define the riskiness of a gamble as the reciprocal of the absolute risk aversion (ARA) of an individual with constant ARA who is indifferent between taking and not taking that gamble. We characterize this index by axioms, chief among them a “duality” axiom which, roughly speaking, asserts...

In the expected-utility theory of the monetary value of a statistical life, the so-called "dead-anyway" effect discovered by Pratt and Zeckhauser (1996) asserts that an individuals' willingness to pay (WTP) for small reductions in mortality risk increases with the initial level of risk. Their...

This paper states necessary and sufficient conditions for the existence, uniqueness, and updating according to Bayes´ rule, of subjective probabilities representing individuals´ beliefs. The approach is preference based, and the result is an axiomatic subjective expected utility model of...
