This paper uses a novel experimental design to study the contagion of pro- and antisocial behavior and the role of social proximity among peers. Across systematic variations thereof, we find that anti-social behavior is generally more contagious than pro-social behavior. Surprisingly, we also...

Little is known about the underlying mechanisms of behavioral contagion, in particular with respect to differences in contagion of pro- versus anti-social behavior. Our principal contribution is the use of a novel experimental approach that enables us to analyze the contagion of behavior under...

Understanding the proximate and ultimate sources of human cooperation is a fundamental issue in all behavioural sciences. In this article we review the experimental evidence on how people solve cooperation problems. Existing studies show without doubt that direct and indirect reciprocity are...

This chapter presents some insights from basic behavioural research on the role of human pro-social motivation to maintain social order. I argue that social order can be conceptualised as a public good game. Past attempts to explain social order typically relied on the assumption of selfish and...

This paper focuses on belief distortion in the context of lying decisions. We employ a twostage variant of the "dice under the cup" paradigm, in which subjects' beliefs are elicited in stage 1 before performing the dice task in stage 2. In stage 1, we elicit the subjects' beliefs about (i)...

Is punishment of free riders driven by descriptive social norms of cooperation and punishment? We conduct experiments in which participants interact in a one-shot social dilemma with punishment. We study how punishment of free riders is influenced by behavior among members of a payoff-irrelevant...
