Nutritional Intake and Poverty in Mexico: 1984–2010
利用1984至2010年墨西哥家庭调查数据，研究发现人均卡路里摄入量随时间下降，营养不足问题加剧，尤其对最贫困群体影响显著，而营养价格上涨仅能部分解释这一下降。
Abstract Using nutritional information of food items acquired by each household, we evaluate how Mexico's nutritional deficiency (calorie and protein) has changed over time. Our extensive dataset combines household surveys from 1984, 1989, 1992, 1996, 2000, 2004, 2006, 2008 and 2010. We find per capita calorie intake has decreased over time for both urban and rural households. The pattern is similar to the case of India, where a decline in calorie intake between 1983 and 2005 has been documented. In both urban and rural areas, nutritional deficiency is increasing over time. Unlike the case of India, we find strong declines in calorie intake for the bottom expenditure quartile of the population. We find that increased prices of nutrients can only partly explain the calorie and protein intake drop.
