Policymakers have been puzzled to observe that food stamp households appear more likely to be food insecure than observationally similar eligible nonparticipating households. We reexamine this issue allowing for nonclassical reporting errors in food stamp participation and food insecurity. Extending the literature on partially identified parameters, we introduce a nonparametric framework that m...

We use propensity scores to evaluate the effect of Food Stamps on food insecurity, a measure of inadequate food supply. Data come from the Early Childhood Longitudinal Study–Kindergarten Cohort. Propensity scores offer an advantage over traditional linear regression methods because they address omitted variable bias associated with Food Stamp use by matching similarly situated treatment and con...

Refugees were given a 5-year exemption from rules...

The new update of the STAMP program is given version 8.30 and it contains the facility to generate Ox code for the model that is estimated in STAMP. It complements the Batch code generator in STAMP. It is particularly useful for those who use Ox regularly as their programming environment for analysing time series. In this short overview of the Batch and Ox code generators in OxMetrics for the S...

the Food Stamp Nutrition Education Program (FSNEP). UC Cooperative Extension specialists need dependable and consistent evaluation data to develop curriculum and staff training materials. Evaluation tools can also demonstrate the effectiveness of such programs, and can help nutrition educators tailor them to the specific needs of diverse populations. For example, if evaluation data indicates th...
