Cows, Missing Milk Markets, and Nutrition in Rural Ethiopia
研究埃塞俄比亚农村市场不完善时，养牛对儿童营养的直接作用，发现养牛能增加儿童牛奶摄入、促进身高增长并减少发育迟缓，而市场发展可替代家庭养牛。
In rural economies encumbered by significant market imperfections, farming decisions may partly be motivated by nutritional considerations, in addition to income and risk factors. These imperfections create the potential for farm assets to have direct dietary impacts on nutrition in addition to any indirect effects via income. We test this hypothesis for the dairy sector in rural Ethiopia, finding that cow ownership raises children’s milk consumption, increases linear growth, and reduces stunting. We also find that household cow ownership is less important where there is good access to local markets, suggesting that market development can substitute for household cow ownership.
