Risk-sharing networks
This paper considers the formation of risk-sharing networks. Following empirical findings, we build a model where pairs form links, but a population cannot coordinate links. As a benchmark, individuals commit to share monetary holdings equally with linked partners. We find efficient networks can (indirectly) connect all individuals and involve full insurance. But equilibrium networks connect fe...
متن کاملRisk-sharing and contagion in networks∗
We investigate the trade-off between the risk-sharing gains enjoyed by more interconnected firms and the costs resulting from an increased risk exposure. We find that when the shock distribution displays “fat” tails, extreme segmentation into small components is optimal, while minimal segmentation and high density of connections are optimal when the distribution exhibits “thin” tails. For less ...
متن کاملFood Sharing and Nonhuman Reciprocal Altruism
Feeding on food that it has foraged is of great importance to ensure the fitness of an animal. Giving up this food for a conspecific is thus one of the most prominent examples of altruism. Although it may bear immediate costs for the donor, sharing food may however be beneficial on the long term. There are various examples of food sharing in the animal kingdom, most of which can be explained by...
متن کاملRisk-sharing networks and farsighted stability
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...
متن کاملRisk-sharing networks and insurance against illness
Most risk-sharing tests on developing country data are conducted at the level of the village; generally, the full risk-sharing hypothesis is rejected. This paper uses detailed data on all insurance networks within a village in Tanzania; networks are not clustered but largely overlapping. We test whether full risk-sharing occurs within these networks. While village level full-insurance cannot be...
