 note = {RoSCAs are financial institutions organized by the local people themselves and they are often observed in developing countries.  In the bidding RoSCAs, the order to take the fund is decided based on the amount of discount offered by bidders. Therefore it reflects the subjective discount rate of each participant. However the studies which calculate the interest rates based on the data of discounts are very few. It is partly because a united calculation method for bidding RoSCAs does not exist, though two ways, Okura method and Internal Rate of Return, were found among the previous studies. The main purpose of this paper is to understand the characteristics of the two ways and test their adequacy, by applying them to the real data of case studies. The result shows that both ways have shortcomings and which one is more appropriate depend on the financial environment for the participants.},
