The human mind is not a general problem solving machine. Instead of deliberately, consciously and serially processing the available information, men can rely on routines, rules, roles or affect for the purpose. They can bring in technology, experts or groups. For all of these reasons, men have a...

Socio-economic decisions are commonly explained by rational cost vs. benefit considerations, whereas person variables have not usually been considered. The present study aims at investigating the degree to which dispositional power motivation and affective states predict socio-economic...

In this experimental study, involving subjects from Abu-Dis (West Bank), Chengdu (China), Helsinki (Finland), and Jerusalem (Israel), we test for a presentation bias in a two-person cooperation game. In the positive frame of the game, a transfer creates a positive externality for the opposite...

We discuss survey evidence on individuals' willingness to sanction norm violations – such as evading taxes, drunk driving, fare dodging, or skiving off work – by expressing disapproval or social exclusion. Our data suggest that people condition their sanctioning behavior on their belief...

One possible solution to mitigate the negative influences of conflict which has been proposed in the literature is to subject the relevant parties to education. Education can take two forms: increasing an individual's human capital on the one hand, increasing her social capital on the other...

In recent debates, morality or social norms have been proposed as an instrument to reduce conflict behavior. As the argument goes, moral people will not engage in socially not-tolerated behavior or, less so than amoral people. Analyzing this question in the framework of contest theory, we find...

Public good provision is often local and also affects bystanders. Is provision harder if contributions harm bystanders, and is provision easier if outsiders gain a windfall profit? In an experiment we observe that both positive and negative externalities reduce provision levels whenever actors...

The novel part of this paper is a model of the principle of proportionality, as the cornerstone of the doctrine of fundamental rights. German law, and with some modifications also the law of the European Community and the European Convention on Human Rights, do not categorically outlaw...

We study how cooperative behavior reacts to selective (favorable or unfavorable) pre-play information about the cooperativeness of other, unrelated groups within an experimental framework that is sufficiently rich for conflicting behavioral norms to emerge. We find that cooperation crucially...

Both in the field and in the lab, participants frequently cooperate, despite the fact that the situation can be modelled as a simultaneous, symmetric prisoner’s dilemma. This experiment manipulates the payoff in case both players defect, and explains the degree of cooperation by a combination...
