We study persuasion effects in experimental ultimatum games and find that Proposers' payoffs significantly increase if, along with offers, they can send messages which Responders read before deciding. Higher payoffs are driven by both lower offers and higher acceptance rates

This paper extends the concept of weak renegotiation-proof equilibrium (WRP) to allow for costly renegotiation and shows that even small renegotiation costs can have dramatic effects on the set of equilibria. More specifically, the paper analyzes the infinitely repeated Bertrand game. It is...

We find that cognitive abilities, educational attainment, and some personality traits indirectly affect ideological preferences through changes in income. The effects of changes in personality traits on ideology directly and indirectly through income are in the same direction. However, the...

We show that the standard trust question routinely used in social capital research is importantly related to cooperation behavior and we provide a microfoundation for this relation. We run a large-scale public goods experiment over the internet in Denmark and find that the trust question is a...

We show that the anticipation of COVID-19 vaccines reduces voluntary social distancing. In a large-scale preregistered survey experiment with a representative sample, we study whether providing information about the safety, effectiveness, and availability of COVID- 19 vaccines affects compliance...

Recent experimental evidence suggests that noisy behavior correlates strongly with cognitive ability. This puts previous studies that found a negative relation between cognitive ability and risk aversion into perspective and in particular raises the question of how to achieve robust inference in...

Since the financial crisis, the behavior and personality traits of finance professionals have come under scrutiny. As comprehensive scientific findings are lacking, we run artefactual field experiments with finance professionals and a random sample of the working population to investigate...

Recent experimental studies suggest that risk aversion is negatively related to cognitive ability. In this paper we report evidence that this relation might be spurious. We recruit a large subject pool drawn from the general Danish population for our experiment. By presenting subjects with...
