This paper shows that reciprocity has powerful implications for many economic domains. It is an important determinant in the enforcement of contracts and social norms and enhances the possibilities of collective action greatly. Reciprocity may render the provision of explicit incentive...

In this paper we study experimentally four remedies to overcome inefficiencies that arise from the incompleteness of contracts. These remedies are reciprocity, repeated game effects, social embeddedness, and incentive contracts. In our baseline treatment we find that reciprocity is a powerful...

A matching model with labor/leisure choice and bargaining frictions is used to explain (i) differences in GDP per hour and GDP per capita, (ii) differences in employment and hours worked (per capita and per worker), (iii) differences in the proportion of part-time work across countries. The...

In this paper we analyze the behavioral consequences of transparent wage distributions on workers' motivation. We study a simple gift-exchange game with one principal and three agents in two different treatments. In the first treatment, agents are not informed about their co-workers' wages and...

This paper proposes an explanation for observed differences in the business cycle volatility of employment and unemployment across a sample of OECD countries. Using an incomplete markets variant of the fair wage real business cycle model, increases in the gross replacement rate of public...

This paper presents a formal theory of reciprocity. Reciprocity means that people reward kind actions and punish unkind ones. The theory takes into account that people evaluate the kindness of an action not only by its consequences but also by the intention underlying this action. The theory...

Prior research demonstrates a willingness to incur costs to punish norm violators. But, how strong are the motives underlying such acts? Will people rely on "excuses" to avoid acting on costly punishment intentions, as with other costly pro-social acts? In a laboratory experiment, we find that...
