Food and Cash Transfers: Evidence from Colombia
研究哥伦比亚有条件现金转移计划下贫困人口的食品恩格尔曲线，发现消费增加10%会使食品支出份额下降1%，但计划本身却提高了食品份额，可能与女性议价能力增强有关。
We study food Engel curves amongst the poor population targeted by a conditional cash transfer programme in Colombia. After controlling for the endogeneity of total consumption and for the price variability across villages, our estimates imply that an increase in consumption by 10% would lead to a decrease of 1% in the share of food. However, quasi-experimental estimates of the impact of the programme show that the share of food increases. This result is not inconsistent with the hypothesis that the programme could increase the bargaining power of women, inducing a more than proportional increase in food consumption. © 2011 The Author(s).
