This paper presents a model of real effort provision in conjunction with social preference theory to predict how individuals exert effort to replace an exogenously determined "state of the world" with a preferred social outcome. Binary dictator games and real effort tasks are used to examine...

The conflict between pro-self and pro-social behaviour is at the core of many key problems of our time, as, for example, the reduction of air pollution and the redistribution of scarce resources. For the well-being of our societies, it is thus crucial to find mechanisms to promote pro-social...

In the vast majority of laboratory experiments documenting the existence of reciprocity subjects are endowed with windfall funds. In many environments with salient fairness considerations such endowments are known to inflate subjects' other-regarding behavior, thereby creating a so-called...

In the vast majority of experiments documenting the existence of reciprocity subjects are endowed with windfall funds. In some situations such endowments might create a so-called “house money effect”. We identify two reasons why the source of endowment might matter for negative reciprocity:...

This paper introduces a model of social preferences featuring a single parameter representing an individual's disposition to share resources with others. The parameter reacts to observed behavior of others in a clearly defined manner. Therefore, the model allows the numerical analysis of...

In this paper we investigate the effect of moral suasion on ingroup favouritism. We report a well-powered, pre-registered, two-stage 2x2 mixed-design experiment. In the first stage, groups are formed on the basis of how participants answer to a set of questions, concerning non-morally relevant...

The most successful human societies are those that have found better ways to promote cooperative behaviour. Yet, cooperation is individually costly and, therefore, it often breaks down, leading to enormous social costs. In this article, I review the literature on the mechanisms and interventions...

In the vast majority of laboratory experiments documenting the existence of reciprocity subjects are endowed with windfall funds. In many environments with salient fairness considerations such endowments are known to inflate subjects’ other-regarding behavior, thereby creating a so-called...

This paper presents a model of real effort provision in conjunction with rational social preference theory to predict how individuals exert effort to replace an exogenously determined “state of the world” with a preferred social outcome. Binary dictator games and real effort tasks are used...

Using James Buchanan's "Samaritan's Dilemma" as a basic example, this paper analyses the problems that have to be solved if strategic behavior is necessary to escape from dilemma situations by changing the opponents' incentives. These problems are addressed within one-shot games as well as...
