This report provides a comprehensive overview of climate cost modelling, from the perspective of damage costs and mitigation costs respectively. It also provides guidance for policymakers on which framework shall be used to derive climate costs for different policy objectives. For both...

Die Covid-19-Pandemie verursacht weltweit erhebliche Verwerfungen in Gesellschaft und Wirtschaft. Kurz- und mittelfristigen Finanzhilfen zur Abmilderung der akuten Folgen von Corona müssen so ausgerichtet werden, dass sie gleichzeitig den langfristig nötigen Wandel hin zu einer nachhaltigen...

The higher our aspirations, the higher the probability that we have to adjust them downwards when forming more realistic expectations later on. This paper shows that the costs induced by high aspirations are not trivial. We first develop a theoretical framework to identify the factors that...

By now there is substantial experimental evidence that people make use of "moral wiggle room" (Dana et al., 2007), that is, they tend to exploit moral excuses for selfish behavior. However, this evidence is limited to dictator games. In our experiment, a trust game variant, we study whether...

Using a laboratory experiment, we examine whether voluntary monetary sanctions induce subjects to coordinate more efficiently in a repeated minimum effort coordination game. While most groups first experience inefficient coordination in a baseline treatment, the efficiency increases...

We investigate to what extent genuine social preferences can explain observed other-regarding behavior. In a social dilemma situation (a dictator game variant), people can choose whether to learn about the consequences of their choice for the receiver. We find that a majority of the people that...

We conduct a modified dictator game in order to analyze the role self-image concerns play in other-regarding behavior. While we generally follow Konow (2000), a cognitive dissonance-based model of other-regarding behavior in dictator games, we relax one of its assumptions as we allow for...

We study the relation between people's personal values and environmentally friendly consumption behavior. We first assessed subjects' personal values using the Aspiration Index. Then subjects participated in a laboratory supermarket offering organic and conventional food products and different...
