We experimentally test overconfidence in investment decisions by offering participants the possibility to substitute their own for alternative investment choices. Overall, 149 subjects participated in two experiments, one with just one risky asset, the other with two risky assets. Overconfidence...

Bidding challenges learning theories, since with the same bid, experiences vary stochastically: the same choice can result in either a gain or a loss. In such an environment the question arises how the nearly universally documented phenomenon of loss aversion affects the adaptive dynamics. We...

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

This paper examines ¯nite parimutuel betting games with asymmetric information, with par-ticular attention to di®erences between sequential and simultaneous settings, and betweenfully rational and myopic (\price taking") behavior. In the simultaneous parimutuel market,all (symmetric and...

Most large-scale economic experiments use a between-subjects random incentive system-BRIS-which selects a subset of the participants at random and offers real payment only to the selected participants. We evaluate the relative impact of nominal payoffs and the selection probability on the...
