The price mecanism is the primary means of information transferin decentralized economic systems. High prices indicate highdemand, whereas low prices indicate low demand. Thus prices arethe signals for accelerating or slowing production. However, usingsequential, multi-unit auctions, we show...

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 study experimentally how taxpayers choose between two taxregimes to fund a public good. The first-best tax regime imposes ageneral, distortion-free income tax. However, this tax cannot be enforced.The second-best alternative supplements the income tax by a specificcommodity tax. This tax...

We present an experimental study on the wasted resources associated with tax evasion. The waste arises from taxpayers and tax authorities, investing costly effort in concealment, respectively detect ion, of tax evasion. We show that (socially ineffcient) efforts depend positively on the...

We study the influence of gender on economic decision making in a two-person bargaining game. By testing hypotheses derived from evolutionary psychology and social role theory, we find that (1) gender per se has no significant effect on behavior, whereas (2) gender pairing systematically affects...

This paper provides an overview on the simulations andexperiments we have done in order to better understandhuman-agent interaction in a market environment. We findthat the introduction of software agents does not necessarilyinduce a more efficient market. More surprisingly,information on the...

This paper investigates distributive justice using a fourfold experimental design:The ignorance and the risk scenarios are combined with the self-concernand the umpire modes. We study behavioral switches between self-concernand umpire mode and investigate the goodness of ten standards of...
