A goal of means testing is to maximize the coverage of benefits to eligible recipients while minimizing the leakage of benefits to those not in the targeted group. As eligibility requirements become more precisely defined or strictly enforced, leakage is reduced but administrative costs and participant burden increase. The focus of the conference is on how income volatility affects these tradeoffs for domestic food assistance programs. Specifically, we are interested in research on income volatility and the movement in and out of program eligibility, the decision to participate, compliance over time, and program costs. For example, what are the behavioral implications of income volatility for the level, frequency, and duration of transfer-program participation? How important is income volatility in determining program eligibility? What is the impact of fluctuating income on administrative and transaction costs of income-tested transfer programs? While emphasis will be placed on food assistance programs such as WIC, the Food Stamp and the National School Lunch Programs, papers dealing with other income transfer programs, domestic or international, are of potential interest, as are papers dealing with multiple-program interactions or methodological issues related to income measurement.
