Food Insecurity in Vulnerable Populations: Coping with Food Price Shocks in Afghanistan

Abstract Based on data from Afghanistan collected prior to and during the 2007‐2008 food price crisis, this paper illustrates that caloric intake is an ineffectual indicator for monitoring the onset of food insecurity. Unconditional Quantile Regression estimates indicate that the most vulnerable of households, which cannot afford to make substantial cuts to calories, exhibit no decline in caloric intake in response to increasing wheat prices. In contrast, households with high‐calorie diets experience large declines. The estimates also reveal declines in dietary diversity across the entire distribution of households. The most vulnerable households may be sacrificing diet quality to maintain calories, with the potential for serious and long‐term health consequences.
