In contrast to the assumptions of standard economic theory, recent experimental evidence shows that the income of peers has a systematic impact on observed degrees of risk aversion. This paper reports the findings of two experiments examining the impact of income inequality on risk preferences...

In einer Studie hat das Umweltbundesamt (UBA) die Konsequenzen eines Tempolimits auf Autobahnen für die Treibhausgasemissionen im deutschen Verkehrssektor berechnet. Dabei wurde gezeigt, dass ein generelles Tempolimit von 130 km/h die Emissionen um 1,9 Mio. t CO2-Äquivalente pro Jahr...

Aktuelle Studien haben berechnet, dass das Elektroauto bereits beim jetzigen Strommix in Deutschland eine positive Klimabilanz besitzt. Der Autor stellt jedoch fest, dass diese Studien den erhöhten Stromverbrauch, der aus dem Ausbau der Elektromobilität resultiert, vernachlässigen. Er zeigt,...

This study tests the prediction that perceived corruption reduces ethical behavior. Integrating a standard "cheating" experiment into a broad household survey in rural Thailand, we find clear support for this prediction: respondents who perceive corruption in state affairs are more likely to...

Prenatal androgen exposure affects the brain development of the fetus which may facilitate certain behaviors and decision patterns in the later life. The ratio between the lengths of second and the fourth fingers (2D:4D) is a negative biomarker of the ratio between prenatal androgen and estrogen...

Economic theory suggests that the deterrence of deviant behavior is driven by a combination of severity and certainty of punishment. This paper presents the first controlled experiment to study a third important factor that has been mainly overlooked: the swiftness of formal sanctions. We...

Social norms, also called social comparison nudges, have been shown to be particularly effective in promoting healthy food choices and environmentally friendly behaviors. However, there is limited evidence on the effectiveness of these nudges for promoting sustainable and climate-friendly food...

Problem gamblers discount delayed rewards more rapidly than do non-gambling controls. Understanding this impulsivity is important for developing treatment options. In this article, we seek to make two contributions: First, we ask which of the currently debated economic models of intertemporal...

Recent studies in the marketing literature developed a new method for eliciting willingness to pay (WTP) with an open-ended elicitation format: the Range-WTP method. In contrast to the traditional approach of eliciting WTP as a single value (Point-WTP), Range-WTP explicitly allows for preference...

Several experimental studies observed substantial violations of transitivity in decisions between risky lotteries over monetary outcomes. The goal of our experiment is to test whether these violations also affect the evaluation of health states. A particular feature of our experimental design is...
