This paper reports on RatDemo, an example program for the application of RatImage, the Research Assistance Toolbox for computerized human behavior experiments. The complete source code of this short experiment program is listed and briefly discussed. Since RatDemo combines several central...

This paper reports on RatImage, version 3.30. The extended features are presented. RatImage 3.30 is fully downward compatible to the first published version of the Research Assistance Toolbox for Computer-Aided Human Behaivor experiments, RatImage 3.10. This paper is an addendum to the manula of...

If payoffs are tickets for binary lotteries, which involve only two money prizes, then rationality requires expected value maximization in tickets. This payoff scheme was increasingly used to induce risk neutrality in experiments. The experiment presented here involved lottery choice and...

This paper reports an option pricing experiment on the binomial model, which has been conducted with professional traders of financial assets. The experimental results are compared to a corresponding experiment with students. The data show that professional traders achieve lower arbitrage...

Essential characteristics of corruption are (1) a reciprocity relationship between briber and public official, (2) negative welfare effects, and (3) high penalties when discovered. We separate the influences of these factors in an experiment. In a two-player game reciprocation is economically...

Dieser Aufsatz beschreibt ein Optionsbewertungsexperiment zum Binomialmodell, das mit professionellen Tradern von Finanztiteln durchgeführt wurde. Die Ergebnisse dieses Experiments werden mit denen eines entsprechenden Versuchs mit Studenten verglichen. Es zeigt sich, daß die professionellen...

In a bribery experiment, we test the hypothesis that distributive fairness considerations make relatively well-paid public officials less corruptible. Corrupt decisions impose damages to workers whose wage is varied in two treatments. However, there is no apparent difference in behaviour.

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 spring 2000, the British government auctioned off licences for Third Generation mobile telecommunications services. In the preparation of the auction, two designs involving each a hybrid of an English and a sealed-bid auction were suggested by the government: a discriminatory and a uniform...

The rise of a new power may lead the dominant power to seek a preventive war. We study this scenario in an experimental two-stage bargaining game. In each stage, the rising power makes a bargaining offer and the declining power must choose whether to accept it or fight. Between the two stages,...
