The Impact of Food Stamps on Food Expenditures: Rejection of the Traditional Model
研究发现，对于正常食品购买超过券面额的食品券领取者，食品券对家庭食品支出的影响显著大于等额现金，否定了传统经济学模型的预测。
Abstract For food stamp recipients whose normal food purchases exceed their coupon allotment, the traditional economic model predicts that the impact of food stamps on food spending will be the same as for an equal cash transfer. The Tobit analysis in this study indicates that, for these recipients, food stamps have a substantially greater impact on at‐home food expenditures than an equal amount of cash income. These results reject the traditional model. Several possible explanations of this behavior are discussed.
