Date of Defense 2009-09-25 Availability unrestricted AbstractThis dissertation is composed of three essays that analyze the significance of the Food Stamp Program (FSP) for low-income households. The first essay entitled “Intensity of Food Stamp Use and Transient and Chronic Poverty: Evidence from the Panel Study of Income Dynamics” examines the impact of intensity of use of FSP benefits on household exposure to transient and chronic poverty with respect to food and housing expenditures. The study finds that FSP is used for both long-term expenditure support and as a smoothing mechanism before the welfare reform, and only for smoothing expenditures after the welfare reform. Factors that influence both components of poverty are number of children, human capital, minority status and local economic conditions. Another finding is that shorter recertification periods reduce the length of FSP use, and indirectly result in higher poverty.
The second essay entitled “The End of the Paper Era in the Food Stamp Program: The Impact of Electronic Benefits on Program Participation” documents the impact of the implementation of the statewide Electronic Benefits Transfer (EBT) system on household participation behavior in the entire period of nationwide implementation. The major finding is that the switch from paper coupons to EBT cards induces participation among eligible households, most likely by reducing the stigma associated with FSP participation. The effect of the EBT system on participation probabilities is the largest among households residing in the rural South, those not headed by a single mother or those with a White household head.
The third essay entitled “The Dynamics of Food Stamp Program Participation: A Lagged Dependent Variable Approach” investigates the existence of state dependence and its sources by analyzing the dynamics of participation in the FSP using a lagged dependent variable approach. Results show that FSP receipt in the previous period is an important determinant of current FSP receipt. Estimated persistence rates declined significantly after 1996, suggesting that long-term welfare dependency was reduced after the welfare reform, at least with respect to the FSP. The source of state dependence in FSP participation among low-income households is mostly structural implying that a welfare trap does exist for these households.
