Are fruit and vegetable voucher policies cost-effective?
研究结合经济模型与健康模型，评估针对低收入人群的水果蔬菜代金券政策的经济与健康效果，发现精准针对最低收入人群的代金券比减税政策更具成本效益。
We quantify the economic and health effects of a fruit and vegetable (F&V) voucher policy designed for increasing F&V consumption among low-income consumers. The analysis combined two models: an economic model which predicts how F&V consumption is affected by a change in policy, and a health model which evaluates the impact of a change in F&V consumption in terms of death avoided and life-years saved. We find that targeted F&V voucher policies can be more cost-effective than non-targeted policies based on tax decreases, but only when the targeted policy is focused narrowly on the lowest income consumers.
