In the context of eliciting preferences for decision making under risk, we ask the question: “which might be the ‘best’ method for eliciting such preferences?”. It is well known that different methods differ in terms of the bias in the elicitation; it is rather less well-known that...

In his ‘Simple model of herd behaviour’, Banerjee (1992) shows that – in a sequential game – if the first two players have chosen the same action, all subsequent players will ignore their own information and start a herd, an irreversible one. The points of strength of Banerjee’s model...

We present an experimental game in the p-beauty framework. Building on the definitions of boundary and interior equilibria, we distinguish between ‘speed of convergence towards the game-theoretic equilibrium' and ‘deviations of the guesses from the game-theoretic equilibrium'. In contrast to...

This paper purports to provide experimental evidence explaining a number of stylized facts associated with the behaviour of financial returns, in particular, the fat tailed nature of their distribution and the persistence in their volatility. By means of a laboratory experiment, we will...

The study investigates protective responses in low probability and high loss risk situations. Particularly, it (1) detects individual protection valuations to variations in probability versus to variations in loss for payment decisions and choice decisions, (2) elicits the threshold probability...

Seminal models of herd behaviour and informational cascades point out the existence of information negative externalities, and propose to destroy information in order to achieve social improvements. Although in the last years many features of herd behaviour and informational cascades have been...

Different from previous studies that use a best estimate, interval, or sets of probabilities, we represent the degree of ambiguity through levels of information provided to subjects. The willingness to pay is higher when more amount of information is provided.

In the 40's and early 50' two decision theories were proposed and have since dominated the scene of the fascinating field of decision-making. In 1944 - when von Neumann and Morgenstern showed that if preferences are consistent with a set of axioms then it is possible to represent these...

We use a two-person linear voluntary contribution mechanism with stochastic marginal benefits from the public good to examine the effect of imperfect information on contributions levels. To assess prior risk attitudes, individual valuations of several risky prospects are elicited via a...
