We investigate the role of affect and deliberation on social preferences. In our laboratory experiment subjects decide on a series of mini Dictator games while they are under varying degrees of cognitive load. The cognitive load is intended to decrease deliberation and therefore enhance the...

People self-assess their relative ability when making career choices. Thus, confidence in own abilities is likely an important factor for selection into various career paths. In a sample of 711 first-year students we examine whether there are systematic differences in confidence levels across...

Instructors can use a computerized experiment to introduce students to imperfect competition in courses on introductory economics, industrial organization, game theory, and strategy and management. In addition to introducing students to strategic thinking in general, the experiment serves to...

Antisocial punishment—punishment of pro-social cooperators—has shown to be detrimental for the efficiency of informal punishment mechanisms in public goods games. The motives behind antisocial punishment acts are not yet well understood. This article shows that inequality aversion predicts...

We explore the role played by trade costs for the home bias in trade. In a series of Cournot duopoly experiments with a home and an export market, we compare output choices when firms face different levels of export costs. We find that there is two-way trade in identical products and that firms...

A substantive amount of lab experimental evidence suggests that the norm of reciprocity has important economic consequences. However, it is unclear whether the norm of reciprocity survives in a natural and competitive environment with experienced agents. For this purpose we analyze data from a...

"Winner-take-all" markets (i.e., markets in which the relative and not the absolute performance is decisive) have gained in importance. Such markets have a tendency to provoke inefficiently many entries. We investigate such markets in an experiment and show that there are even more inefficient...

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