Resource | Research and Data | National Academy of Sciences/IOM Review of WIC Food Packages: An Evaluation of White Potatoes in the Cash Value Voucher: Letter Report

At the request of the U.S. Department of Agriculture, an expert Institute of Medicine (IOM) committee is undertaking a comprehensive review of the food packages used in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) to bring the program into alignment with current dietary guidelines.

Resource | Research and Data | Assessing/Improving Operations The Evaluation of the Alabama Food Stamp Cash-Out Demonstration

A fundamental issue in the design of the Food Stamp Program (FSP) is the form benefits should take. Advocates of the current coupon system argue that coupons are a direct and inexpensive way to ensure that food stamp benefits are used to purchase food; that, despite some evidence of fraud and benefit diversion under the current system, the unauthorized use of food stamps is relatively limited; and that coupons provide some measure of protection to food budgets from other demands on limited household resources. Advocates of replacing coupons with cash argue that the current system limits the food purchasing choices of participants, places a stigma on participation; and entails excessive costs for coupon issuance, transaction, and redemption.
