We use fluctuations of female sex hormones occurring naturally over the menstrual cycle or induced by hormonal contraceptives to determine the importance of sex hormones in explaining gender differences in competitiveness. Participants in a laboratory experiment solve a simple arithmetics task...

We examine how multitasking affects performance and check whether women are indeed better at multitasking. Subjects in our experiment perform two different tasks according to three treatments: one where they perform the tasks sequentially, one where they are forced to multitask, and one where...

The supposed irrelevance of historical costs for rational decision making has been the subject of much interest in the economic literature. In this paper we explore whether individual decision making under risk is affected by the cost of the supplied information. Outside of the lab, it is...

We provide an example for an errors in variables problem which might be often neglected but which is quite common in lab experimental practice: In one task, attitude towards risk is measured, in another task participants behave in a way that can possibly be explained by their risk attitude. How...

Whistle-blowing by employees plays a major role in uncovering corporate fraud. Various recent laws aim at improving protection of whistle-blowers and enhancing their willingness to report. Evidence on the effectiveness of such legislation is, however, scarce. Moreover, critics have raised...

Inspired by Fröhlich and Oppenheimer (1990), an experimental survey in the lab was designed to find out if preferences for three different redistribution schemes differ under a veil of ignorance. The three schemes are a stylized version of the status quo German welfare state (A), a control...

We investigate the trade-off between the opportunity costs of decisions and their quality in a simple model. In a lab experiment, we introduce exogenous variation in the opportunity costs of time. Contrary to claims in the previous literature, we show that using more time when making small-stake...

Leaders often have to weigh ethical against monetary consequences. Such situations may evoke psychological costs from being dishonest and dismissing higher monetary benefits for others. In a within-subjects experiment, we analyze such a dilemma. We first measure individual dishonest behavior...
