Maternal Nutrition Knowledge and the Demand for Micronutrient-Rich Foods: Evidence from Indonesia
研究利用印度尼西亚农村家庭数据，发现拥有营养知识的母亲虽食品总预算份额不变，但会将更多预算花在富含微量元素的食物上，减少大米支出，且这种差异部分源于教育，但营养知识本身有独立解释力。
This study applies both parametric and non-parametric techniques to a new household data set from rural Indonesia to explain previous findings of a reduced-form relationship between nutrition knowledge and child micronutrient status. Households of mothers with and without nutrition knowledge allocate identical budget shares to food; yet, within the food budget, ‘knowledge’ households allocate substantially larger shares to micronutrient-rich foods and smaller shares to rice than do ‘non-knowledge’ households. These differences are partially attributable to differences in maternal schooling, but nutrition knowledge has additional sources (in particular, access to the village health centre/posyandu) and independent explanatory power in conditioning the demand for micronutrient-rich foods.
