There is a debate about whether risk aversion is the main source of overbidding in a first-price independent private values auction. As an alternative, we adopt a non-expected utility framework, and identify an interpretable property on the probability weighting function which always induces...

Accurate measurements of probabilistic beliefs have become increasingly important both in practice and in academia. Introduced by statisticians in the 1950s to promote truthful reports in simple environments, Proper Scoring Rules (PSR) are now arguably the most popular incentivized mechanisms to...

As in any research field, risk theory has its important questions, results, and paradoxes, as well as its seminal papers and key authors. Louis Eeckhoudt has been a key author in the field of risk theory. To celebrate his many contributions and continue the development of theories of decision...

We consider a prediction market in which traders have heterogeneous prior beliefs in probabilities. In the two-state case, we derive necessary and sufficient conditions so that the prediction market is accurate in the sense that the equilibrium state price equals the mean probabilities of...

What is the effect of future information on today's actions? The answer may help understand, or justify, low investment in the presence of costs, a preference for holding liquid money, self-insurance or precautionary savings motives, environmental preservation and global warming abatement...

This paper considers a common n-agent symmetric rent-seeking game. It derives conditions so that risk-aversion and risk always decrease rent-seeking efforts. These conditions hold for any regular contest success function when risk-averse rent-seekers are also prudent. Under n = 2, prudence is a...

This chapter surveys the economic literature on prevention and precaution. Prevention refers as either a self-protection activity – i.e. a reduction in the probability of a loss – or a self-insurance activity – i.e. a reduction of the loss –. Precaution is defined as a prudent and...
