The Short‐Run Impact of the Healthy Incentives Pilot Program on Fruit and Vegetable Intake
研究评估了美国健康激励试点项目对SNAP参与者水果蔬菜摄入量的短期影响，发现提供30%购买激励后，成人日均摄入量增加0.22杯当量（提高24%），与先前非实验弹性估计一致。
In response to low consumption levels of fruits and vegetables by Supplemental Nutrition Assistance Program (SNAP) participants, the USDA Food and Nutrition Service created the Healthy Incentives Pilot (HIP) to test the efficacy of providing a 30% incentive for purchases of targeted fruits and vegetables (TFVs). Four to six months after implementation, mean daily TFV intake for adult HIP participants was 0.22 cup‐equivalents higher (24% higher) than for control‐group SNAP participants. These impact estimates with a random‐assignment research design generally agree with previously published nonexperimental elasticity estimates, which imply that a pure price reduction of 30% would increase fruit and vegetable consumption by about 20%.
