A bidding rotating savings and credit association (Rosca) is modeled as a sequence of symmetricindependent-private-value auctions with price-proportional benefits to bidders. We estimate a structural econometric model which, by introducing an altruistic component into each bidder's utility...

Conventional wisdom in economics holds that traditional credit and insurance networks are inapt for insuring against covariate risks such as natural hazards. We challenge this claim by examining changes in financial allocations in Rotating Savings and Credit Associations (Roscas), a popular...

We model rotating savings and credit associations (Roscas) among risk-averse participants who experience privately observed income shocks. A random Rosca is not advantageous, whereas a bidding Rosca is if temporal risk aversion is less pronounced than static risk aversion. The payoff scheme of a...
