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

An empirically well-established finding is that equity portfolios are concentrated in the domestic equity market of the investor. Previous theoretical and empirical analyses have mainly focused on institutional explanations and largely neglected individual behavior. In this study we report the...

Dynamics of compliance, depending on audit probability, sanctions, and the time lag between audits, are investigated in a tax experiment. Compliance varied significantly over time: it decreased immediately after an audit and increased afterwards, especially if audits were frequent and sanctions...

This article reports the results of a first-price sealed-bid auction experiment, which has been designed to test the Nash equilibrium predictions of individual bidding behavior. Subjects faced in 100 auctions always the same resale value and competed with computerized bids. Three treatments were...

We conducted a laboratory study with a public goods game in which contributions are not submitted all at once but incrementally as coordinated in real time by a clock. Individuals press a button as soon as the clock equals their willingness to contribute. This public goods institution exploits...

The paper presents the concept of an "imitation equilibrium" and explores it in the context of some simple oligopoly models. The concept applies to normal form games enriched by a "reference structure" specifying a "reference group" for every player. The reference group is a set of other...

Conventions can be narrowly interpreted as coordinated ways of equilibrium play, i.e., a specific convention tells all players in a game with multiple strict equilibria which equilibrium to play. In our view, coordination often takes place before learning about the games. Thus, one has to...

We report an experiment that uses the strategy method (Selten 1967) to elicit subjects' general strategy for playing any 2-person 3x3-game with integer payoffs between 0 and 99. Each two subjects' strategies play 500000 games in each of the 5 tournaments. For games with pure strategy equilibria...

In a cascade experiment subjects are confronted with artificial predecessors predicting in line with the BHW model (Bikhchandani, Hirshleifer and Welch, 1992). Using the BDM mechanism we study subjects' probability assignments based on price limits for participating in the prediction game. We...

We study the value of information in financial markets by asking whether having more information always leads to higher returns. We address this question in an experiment where single traders have different information levels about an asset's intrinsic value. In our treatments we vary the nature...
