Evidences suggest that in some villages of developing countries, agents rely on mutual insurance agreements to deal with income or expenditure shocks. In this paper we analyze which risk-sharing networks can be sustained in the long run when individuals are farsighted rather than myopic, in the sense that they are able to forecast how other agents would react to their actions. In particular, we...
