This paper provides an argument for the advantage of a preference for identity-consistent behaviour from an evolutionary point of view. Within a stylised model of social interaction, we show that the development of cooperative social norms is greatly facilitated if the agents of the society...

While social norms have received great attention within economics, little is known about the role of personal norms. We propose a simple utility framework - which assumes that people care about monetary payoff, social norms, and personal norms - and design a novel two-part experiment to...

People frequently behave non-selfishly in situations where they can reduce their own payoff to help others. It is typically assumed that such pro-social behavior arises because people are motivated by a social preference. An alternative explanation is that they follow a social norm. We test with...

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...

Substantial evidence has accumulated in recent empirical works on the limited ability of the Nash equilibrium to rationalize observed behavior in many classes of games played by experimental subjects. This realization has led to several attempts aimed at finding tractable equilibrium concepts...
