"Socially Close and Socially Distant Connections in Risk Sharing"
Abstract
This paper studies the role of socially close and socially
distant connections in providing informal risk sharing in social
networks.
Socially close connections are considered to be more
effective in enforcing informal risk sharing arrangements, but they may
be more economically similar and less numerous than socially distant
connections, and hence provide fewer risk sharing opportunities. A
simple theoretical framework incorporating these features indicates that
larger networks should yield better risk sharing. More socially close
connections are beneficial. However, socially distant connections become
more valuable when incomes of socially close households are
sufficiently positively correlated. I then test the predictions of this
model using data on a large number of village based extended family
networks in rural Mexico. I document that the incomes of socially close
households covary more positively than those of socially distant
households. I find that households in large networks achieve better risk
sharing. However, this effect is driven primarily by socially distant
connections, suggesting that opportunities for risk sharing are
relatively more important in this context.
