Assessing the causal impacts of SNAP, however, is hampered by two key identification problems: endogenous selection into participation and extensive systematic underreporting of participation status.Using data from the National Health and Nutrition Examination Survey (NHANES), we extend partial identification bounding methods to account for these two identification problems in a single unifying framework. Learn more Published Research Deterrence and the Death Penalty: Partial Identification Analysis Using Repeated Cross Sections Authors: John Pepper, Charles Manski Objectives Researchers have used repeated cross sectional observations of homicide rates and sanctions to examine the deterrent effect of the adoption and implementation of death penalty statutes. The empirical literature, however, has failed to achieve consensus. Learn more Published Research Economics The Economics of Food Insecurity in the United States Authors: John Pepper, Craig Gundersen, Brent Kreider Food insecurity is experienced by millions of Americans and has increased dramatically in recent years. Due to its prevalence and many demonstrated negative health consequences, food insecurity is one of the most important nutrition-related public health issues in the U.S. Learn more Published Research Education The Impact of the National School Lunch Program on Child Health: A Nonparametric Bounds Analysis Authors: John Pepper, Craig Gunderson, Brent Kreider Children in households reporting the receipt of free or reduced-price school meals through the National School Lunch Program (NSLP) are more likely to have negative health outcomes than observationally similar nonparticipants. Assessing causal effects of the program is made difficult, however, by missing counterfactuals and systematic underreporting of program participation. Learn more Published Research Ethics Identification of Expected Outcomes in a Data Error Mixing Model with Multiplicative Mean Authors: John Pepper, Brent Kreider We consider the problem of identifying a mean outcome in corrupt sampling where the observed outcome is drawn from a mixture of the distribution of interest and another distribution. Relaxing the contaminated sampling assumption that the outcome is statistically independent of the mixing process, we assess the identifying power of an assumption that the conditional means of the distributions differ by a factor of proportionality.
