Overbidding in sealed-bid second-price auctions (SPAs) has been shown to be persistent and associated with cognitive ability. We study experimentally to what extent cross-game learning can reduce overbidding in SPAs, taking into account cognitive skills. Employing an order-balanced design, we...

Least-Unmatched Price Auctions have become a popular format of TV and radio shows. Increasingly,they are also applied in internet trading. In these auctions the lowest single (unique)bid wins. We analyze the game-theoretic solution of least unmatched price auctions when prize,bidding cost and...

In Buy-It-Now auctions, sellers can post a take-it-or-leave-it price offer prior to an auction. While the literature almost exclusively looks at buyers in such combined mechanisms, the current paper summarizes results from the sellers' point of view. Buy-It-Now auctions are complex mechanisms...

A vast literature shows that individuals frequently violate normative principles in reasoning. In evaluatingthe relevance of these findings for psychology, economics, and related disciplines, it is natural to askwhether reasoning errors reflect random aberrations or systematic biases. One...

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...

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...

A vast literature shows that individuals frequently fail to identify the normative solutionsin logical reasoning tasks. Much attention has been devoted to the study ofthese deviations at the individual level; less effort was exerted to investigate whetherinstitutional settings might facilitate...
