Income Effects of Donated Commodities in Rural Panama
研究巴拿马农村家庭食品支出数据，发现捐赠食品的边际消费倾向与现金收入无显著差异，表明带回家的食品项目可通过收入效应影响食品获取，设计时应最大化捐赠品的市场价值。
Abstract Analyses of food expenditure data from rural households in Panama showed that the marginal propensity to consume food out of additional income in the form of donated food is not different than the marginal propensity to consume food out of money income for households participating in the Veraguas supplemental feeding program. These results suggest that take‐home food programs can have significant income‐mediated impacts on the acquisition of food, and, accordingly, food supplementation programs should be designed to maximize the income value of the donated commodities in terms of prices prevailing in the local markets.
