We investigate how reputational uncertainty and the rate of change of the social environment interact to influence cooperation in social networks. Reputational uncertainty significantly decreases cooperation and welfare, induces more forgiveness toward defectors, and promotes opportunistic play....

Many social networks have the following properties: (i) a short average distance between any two individuals; (ii) a high clustering coefficient; (iii) segregation patterns; the presence of (iv) brokers and (v) hubs. (i) and (ii) define a small world network. This paper develops a strategic...

This paper proposes a dynamic model of bargaining to analyze decentralized markets where buyers and sellers obtain information about past deals through their social network. There is a unique equilibrium outcome which depends crucially on the peripheral (least connected) individuals in each...

This paper presents a bargaining model between individuals belonging to different groups where the equilibrium outcome depends on the communication network within each group.  Belonging to a group gives an informational advantage: connections help to gather information about past transactions...

We present the first empirical study to reveal the presence of implicit discrimination in a non-experimental setting. By using a large dataset of in-match data in the English Premier League, we show that white referees award significantly more yellow cards against non-white players of...

We study individual ability to memorize and recall information about friendship networks using a combination of experiments and survey-based data. In the experi- ment subjects are shown a network, in which their location is exogenously assigned, and they are then asked questions about the...
