Completeness, the most commonly assumed axiom in preference theory,has not received much attention from the experimental literature. Indeed,incomplete preferences model a cognitive phenomenon (an agent's inabilityto compare alternatives), and therefore cannot be directly revealed throughchoice...

We propose an experimental design allowing a behavioral test of the axiom of completeness of individual preferences. The central feature of our design consists in enabling subjects to postpone commitment at a small cost. Our main result is that preferences are significantly incomplete. We use...

We study two person-betting games with inconsistent commonly know beliefs, using an experimentalapproach. In our experimental games, participants bet against one another, each bettorchoosing one of two possible outcomes, and payoff odds are know at the time bets are placed.Bettors’ beliefs are...

This paper examines the occurrence and fragility of information cascades in laboratory experiments.One group of low informed subjects make predictions in sequence. In a matchedpairs design, another set of high informed subjects observe the decisions of the first group andmake predictions....

Our objective in this paper is to assess the acceptability of the ambient tax. Concretely,we ask subjects to choose between (A) an ambient tax and (B) an individual tax system. Incase (A), they actually participate in a game in which their payout depends on all participants'decisions and on...
