An Empirical Investigation into Measurement and Determinants of Food Security
利用2010-2011年加尔各答贫民窟家庭数据，比较基于卡路里和基于体验的粮食安全指标，发现两者方向一致但并非一一对应，且决定因素不同，表明单一政策无法同时解决两种问题。
We examine the association between calorie-based indicators and experiential indicators of food security using data from slum households of Kolkata surveyed in 2010–2011. Experiential indicator is constructed following the United States Household Food Security Survey Module. Calorie based indicator is constructed using household-specific calorie norms. Modelling techniques take account of potential endogeneity in the relationship. The two indicators are aligned in the same direction implying more accurate targeting. However, there is a lack of one-to-one correspondence between the two measures and the drivers of calorie deprivation and food insecurity also differ, suggesting a one-size-fits-all policy cannot address both concerns simultaneously.
