Economic Analysis of Institutions and Policies on Water Resources: Case of South India

为了实现经济发展和满足发展中国家日益增长的人口的需要，水一直是需要的。这项研究分析了近几十年来水资源短缺的印度南部农业水资源的数据。本研究的目的是探讨不同背景和禀赋的农业生产水资源的生产效率和配置效率差异的原因，并提出可持续发展的政策建议。印度农村的发展。本研究的主要成果如下：1.根据在印度南部泰米尔纳德邦的调查，建立了一套可用于政策分析的数据库; 2.提出了一种新的非参数分解效率测度的方法，并将其应用于从实地收集的数据，3.提出了一种新的计算投入品影子价格的方法，以得出投入品补贴政策的政策含义，4.利用时间序列数据确定了井灌系统存在的经济价值。这一研究成果已提交给2007年1月举行的美国农业经济协会冬季会议。与第2和第3项有关的另外两份文件正在准备出版。

Water has been always in demand for the purposes of achieving economic development and meeting the needs of growing population in developing countries. This study analyzed the data on water resources in agriculture in South India, where water has been scarce in the recent decades. This study is part of efforts to find useful policy implications for dealing with the shortage of water resources and the resulted negative consequences on economic and social development.The objectives of this study are to understand reasons for the difference in production efficiency and allocative efficiency among surveyed farms with different backgrounds and endowments on water resources for agricultural production and to derive policy implications for sustainable development in rural India. The followings are the outputs of this study so far.1.A set of database, which is useful for policy analyses, has been created based on our own survey in Tamilnadu in South India,2.A new non-parametric approach to decompose the efficiency measures has been developed and applied to the data which have been collected from the field,3.A new approach to calculate shadow prices of input materials has been also developed to derive policy implications on subsidy policies of input materials, and4.The economic values of the existence of well irrigation systems have been identified using time-series data. This research output has been presented at the Winter meetings of the American Agricultural Economic Association in January 2007. Two other papers related with 2 and 3 are in the process of the preparation for publication.
