Risk Pooling, Risk Preferences, and Social Networks

  • Abigail Barr
  • Orazio Attanasio

Using data from a field experiment conducted in seventy Colombian municipalities, we investigate who pools risk with whom when risk pooling arrangements are not formally enforced.� We explore the roles played by risk attitudes and network connections both theoretically and empirically.� We find that pairs of participants who share a bond of friendship or kinship are more likely to (1) join the same risk pooling group and to (2) group assortatively with respect to risk attitudes.� Also, consistent with our theoretical finding that when there is a problem of trust the process of pooling assortatively with respect to risk preferences is perturbed, we find (3) only weak evidence of such assorting among unfamiliar individuals.
