This paper studies the evolution of both characteristics of reciprocity - the willingness to reward friendly behavior and the willingness to punish hostile behavior. Firstly, preferences for rewarding as well as preferences for punishing can survive evolution provided individuals interact within...

This paper investigates opinion dynamics and social influence in directed communication networks. We study the properties of a generalized boundedly rational model of opinion formation in which individuals aggregate the information they receive by using weights that are a function of their...

Economic inequality may fuel frustration, possibly leading to anger and antisocial behavior. We experimentally study a situation where only the rich can reduce inequality while the poor can express their discontent by destroying the wealth of a rich counterpart with whom they had no previous...

Attitudes towards fairness and redistribution differ along socio-economic lines, resulting in political conflict. To understand the formation of such views and find levers to affect them, we study the role of attention. In a large online experiment, we investigate how subjects allocate their...

People with higher-incomes tend to support less redistribution than lower-income people. This has been attributed not only to self-interest, but also to psychological mechanisms including differing beliefs about the hard work or luck underlying inequality, differing fairness views, and differing...

Mentalising is assumed to be involved in decision-making that is necessary to social interaction. We investigated the relationship between mentalising and two types of strategic games - those involving the choice to cooperate with another for joint gain or compete for own gain and those...
