| Outline of Final Research Achievements |
We investigated the provision and the maintenance of common property resources, where the supply of goods and services tends to constitute a "tragedy of the commons" situation. We selected a water users’ association in Indonesia, in Central Java Province, as case studies. In recent years, new organization of irrigation management systems have been spreading rapidly in this area. Under this new organization, the irrigation association chief is elected based in the size of contribution competitively. Those who contribute the maximum investment to a village's infrastructure, can become the irrigation association chief. The irrigation association chief has incentives to supply irrigation services in order to acquire irrigation fees as income. We estimate the internal rate of return for chief’s investment. We found that the internal rate of return was 41%, higher than the average interest rate of 36% in the village financial market, revealing that it is economically rational behavior.
