Social Hierarchies and Public Distribution of Food in Rural India
研究印度公共粮食分配系统（PDS）中富户与穷户的消费差异，发现PDS运行良好的邦差异显著，运行不佳的邦差异不显著，表明改善PDS需让贫困家庭更易获取。
In this paper, we develop a simple model to show that consumption of PDS food grains is significantly different between rich and poor households in states in which the PDS functions relatively well; in states in which the PDS is non-functional, the difference is not significant. Using household-level data from three recent thick rounds of the consumption expenditure survey (2004–2005, 2009–2010, and 2011–2012), we find evidence in support of the predictions from the model. This suggests that one way to make the PDS functional is to make it more accessible to poor and underprivileged households.
