Welfare effects of selected food-grain policies in India
研究印度政府粮食市场干预政策（如双重价格结构和公共分配计划）对农民供给、总需求及市场出清价格的影响，并计算不同市场假设下的福利效应。
Government's policy interventions in the market for food-grains affect supply as well as demand. In this paper, the welfare effects of certain food-grain policies are analysed while taking into account the interdependence of the various sectors in the economy. Adequate structure is built into the model in order to study the effects of a dual price structure on farmers' supply response, and also the effects of public distribution schemes on the aggregate demand for foodgrains. Policy implications are derived by computing the market clearing prices and their movement under alternative assumptions regarding the nature of the market.
