This paper experimentally studies the effects of competition in an environment where people's actions can not be contractually fixed. We find that, in comparison with no competition, the presence of competition does neither increase efficiency nor does it yield any gains in earnings for the...

This paper addresses the nature, formalization, and neural bases of (affective) social ties and discusses the relevance of ties for health economics. A social tie is defined as an affective weight attached by an individual to the well-being of another individual (‘utility interdependence’)....
