Economic Evaluation of the Farmers' Market Nutrition Program
构建了一个评估食品援助计划的框架，并应用于农贸市场营养计划。该计划通过提供优惠券和信息来增加新鲜果蔬消费。研究发现，仅发放优惠券会降低社会福利，但结合信息分发可纠正市场失灵、提升社会福利。
Abstract A framework is developed to evaluate food assistance programs and is applied to the Farmers' Market Nutrition Program—a program intended to increase consumption of fresh fruits and vegetables (F…V) by providing coupons and information. Because individuals differ, some coupons are unused, some replace existing consumption and simply enhance income, and some induce increased consumption. Results show that coupons alone reduce social welfare because recipients value F…V less than society. However, when coupons are used as a lure to distribute information, demand increases. In a household production framework the program is shown to enhance social welfare by correcting a market failure.
