Declining general trust has become a serious social issue in China in recent years. This paper attempts to understand and analyze this social phenomenon from a social interaction perspective. Based on a repeated prisoners´ dilemma game on networks, it finds that the evolution of general trust...

In this paper we give a clear-cut explanation to the sluggish wage adjustments which are commonly experienced also in face of involuntary unemployment. We prove that unemployment may be the physiological outcome of rational decisions by competing workers who may find it optimal to ask higher...

We perform an experiment on social insurance to provide a laboratory replica of some important features of the welfare state. In the experiment, all individuals in a group decide whether to make a costly effort, which produces a random (independent) outcome for each one of them. The group...

To explain potential sources of wage rigidity this article analyzes a model of reciprocal kindness applied to a repeated ultimatum game with changing and nonzero conflict payoffs. The model is also tested in a laboratory experiment. The results are compatible with the rentsharing approach to...
