The Discussion Paper series aims to disseminate research outputs (including the findings of work in progress) on development issues and development cooperation in the form of academic papers. For the sake of quick dissemination, the papers are not peer-reviewed but assessed by the review committee under the JICA Ogata Sadako Research Institute for Peace and Development (JICA Ogata Research Institute). The views expressed in this paper series are those of the author(s) and do not necessarily represent the official positions of either JICA or the JICA Ogata Research Institute
