Evidence on behavior of experts in credence goods markets raises an important causality issue: Do "fair prices" induce "good behavior", or do "good experts" post "fair prices"? To answer this question we propose and test a model with three seller types: "the good" choose fair prices and behave...

In this paper, we describe what economists have learned about differences between group and individual decision-making. This literature is still young, and in this paper, we will mostly draw on experimental work (mainly in the laboratory) that has compared individual decision-making to group...

Many tournaments are plagued by sabotage among competitors. Typically, sabotage is welfare-reducing, but from an individual’s perspective an attractive alternative to exerting positive effort. Yet, given its illegal and often immoral nature, sabotage is typically hidden, making it difficult to...

Social preferences have been shown to be an important determinant of economic decision making for many adults. We present a largescale experiment with 883 children and adolescents, aged eight to seventeen years. Participants make decisions in eight simple, oneshot allocation tasks, allowing us...

We study experimentally the relationship between distributional preferences and competitive behavior. We find that spiteful subjects react strongest to competitive pressure and win in a tournament significantly more often than efficiency-minded and inequality averse subjects. However, when given...

In an experiment, we study risk-taking of cohabitating student couples, finding that couples’ decisions are closer to risk-neutrality than single partners’ decisions. This finding is similar to earlier experiments with randomly assigned groups, corroborating external validity of earlier results.

Auf dem Gipfel in Amsterdam im Juni 1997 haben sich die Staats- und Regierungschefs der EU-Staaten auf einen Stabilitäts- und Wachstumspakt für die Mitglieder in der Europäischen Wirtschafts- und Währungsunion geeinigt. Welche Auswirkungen und Probleme ergeben sich aus der gegenwärtigen...
