讲座内容简介

The Supplemental Nutrition Assistance Program (SNAP), formerly known as the Food Stamp Program, serves as the largest hunger safety nest in theUnited States. Thorough evaluations of the SNAP program effectiveness at achieving its goals of food security and healthier diets are wanted given the sizable program costs and are essential for utilizing the vast coverage of SNAP program to achieve the largest public health impact.

This study focuses on time factor which is one of the three key factors identified by the Institute of Medicine/ National Research Council committee that are currently absent from the benefit calculation. We tried to answer a remaining unanswered question: how much of the maximum SNAP allotment should be adjusted to address the majority of the potential inadequacy at reaching SNAP program goal?

     We calculate the appropriate scaling factor, k, which can be used to adjust the SNAP benefit amount. The average suggested scaling factor, k, is less than 0.5. We also find out that dual-headed households have the flexibility of spousal time substitution therefore their time constraints are not as tight as the single-headed households and require smaller time-cost adjustment to meet the threshold.
