How Well Does Snap Protect Families Against The Risk Of Food Insecurity And Poor Health During Economic Downturns?, Thomas Deleire, Bradley Hardy, Jay Bhattacharya

University of Kentucky Center for Poverty Research Discussion Paper Series

Our research project addressed the question of how well SNAP and the social safety net protects families against the risk of food insecurity and poor health during economic downturns. Previous research has documented the relationship between reductions in family incomes and food insufficiency and has examined the effects of resources that mitigate the effects of income volatility. The U.S. social safety net, including SNAP, exists to mitigate the deleterious effects of swings in family income, particularly among low- and moderate-income households. This work compares outcomes for lower income families and higher income families in response to economic downturns. To the …

Child Age And Gender Differences In Food Security In A Low-Income Inner-City Population, Robert A. Moffitt, David C. Ribar

University of Kentucky Center for Poverty Research Discussion Paper Series

A long literature in economics concerns itself with differential allocations of resources to different children within the family unit. In a study of approximately 1,500 very disadvantaged families with children in Boston, Chicago, and San Antonio from 1999 to 2005, significant differences in levels of food allocation, as measured by an indicator of food “insecurity,” are found across children of different ages and genders. Using answers to unique survey questions for a specific child in the family, food insecurity levels are found to be much higher among older boys and girls than among younger ones, and to be sometimes higher …

Impact Of Food Insecurity And Snap Participation On Healthcare Utilization And Expenditures, Seth A. Berkowitz, Hilary K. Seligman, Sanjay Basu

University of Kentucky Center for Poverty Research Discussion Paper Series

We tested three hypothesis related to food insecurity and the Supplemental Nutrition Assistance Program (SNAP), America’s largest anti-food insecurity program. We hypothesized that 1)food insecurity would be associated with increased healthcare expenditures, 2)food insecurity would be associated with increased use of emergency department and inpatient services, and 3) SNAP participation would be associated with lower subsequent healthcare expenditures. We used data from the 2011 National Health Interview Survey linked to the 2012-13 Medical Expenditures Panel Survey. We used zero-inflated negative binomial regression to test the relationship between food insecurity and healthcare cost and use. We evaluated the association between SNAP …

Food Store Choice Of Poor Households: A Discrete Choice Analysis Of The National Household Food Acquisition And Purchase Survey, Sofia B. Villas-Boas, Rebecca Taylor

University of Kentucky Center for Poverty Research Discussion Paper Series

Policymakers are pursing initiatives to increase food access for low-income households. However, due in part to previous data deficiencies, there is still little evidence supporting the assumption that improved food store access will alter dietary habits, especially for the poorest of U.S. households. This article uses the new National Household Food Acquisition and Purchase Survey (FoodAPS) to estimate consumer food outlet choices as a function of outlet type and household attributes in a multinomial mixed logit. In particular, we allow for the composition of the local retail food environment to play a role in explaining household store choice decisions and …

The Effect Of Food Price On Food Insecurity And Diet Quality: Exploring Potential Moderating Roles Of Snap And Consumer Competency, Yunhee Chang, Jinhee Kim, Swarn Chatterjee

University of Kentucky Center for Poverty Research Discussion Paper Series

Higher food prices may aggravate household food insecurity and hurt diet quality. Using a sample of low-income households from the National Household Food Acquisition and Purchase Survey (FoodAPS), this study examines whether local food prices affect food insecurity and nutritional quality of foods acquired, and how households use competent consumer behaviors to mitigate any adverse effects of price. Financial management practices, nutrition literacy, and conscientious food shopping practices were considered for consumer competency. Our findings indicate that low-income households in higher-cost areas, regardless of whether they participate in SNAP or not, are more likely to adopt loyalty or other store …

Influence Of Snap Participation And Food Environment On Nutritional Quality Of Food At Home Purchases, Amy Hillier, Benjamin Chrisinger, Tony E. Smith, Eliza Whiteman, Michael Kallan

University of Kentucky Center for Poverty Research Discussion Paper Series

A growing body of research describes how individuals make food shopping decisions in both time and space. The FoodAPS dataset provides a unique opportunity for understanding these patterns among a large sample across income, SNAP status, and settings. We addressed three questions in our research: (1) Where do participants shop for food at home (FAH) and how do individual characteristics interact with store characteristics and distance? (2) How does the nutritional content of foods purchased change as time from SNAP distribution increases? and (3) How does store choice influence the nutritional quality of FAH purchases? We used a conditional logit …

Causes And Consequences Of The Calorie Crunch, Michael A. Kuhn

University of Kentucky Center for Poverty Research Discussion Paper Series

Monthly welfare programs such as the Supplementary Nutrition Assistance Program (SNAP) produce consistent cycles of expenditure and consumption amongst recipients. Food insecurity and negative behavioral outcomes track these cycles. This paper leverages new data from the USDA, the FoodAPS survey, and to answer a variety of questions related to these phenomena: Are consumption and expenditure cycles correlated? Who bears the burden of food shortages at the end of each benefit month? Does diet quality track food expenditure? I find robust expenditure and consumption cycles in the FoodAPS data, but contrary to popular belief, they are only weakly correlated. The youngest …

Trouble In The Tails? What We Know About Earnings Nonresponse Thirty Years After Lillard, Smith, And Welch, Christopher R. Bollinger, Barry T. Hirsch, Charles M. Hokayem, James P. Ziliak

University of Kentucky Center for Poverty Research Discussion Paper Series

Earnings nonresponse in household surveys is widespread, yet there is limited evidence on whether and how nonresponse bias affects measured earnings. This paper examines the patterns and consequences of nonresponse using internal Current Population Survey individual records linked to administrative Social Security Administrative data on earnings for calendar years 2005-2010. Our findings confirm the conjecture by Lillard, Smith, and Welch (1986) that nonresponse across the earnings distribution is U-shaped. Left-tail “strugglers” and right-tail “stars” are least likely to report earnings. Household surveys understate earnings dispersion, reporting too few low and too few extremely high earners. Throughout much of the earnings …

Paternal Incarceration And Children's Food Insecurity: A Consideration Of Variation And Mechanisms, Kristen Turney

University of Kentucky Center for Poverty Research Discussion Paper Series

Despite growing attention to the unintended consequences of paternal incarceration for children’s wellbeing across the life course, little is known about whether and how paternal incarceration is related to food insecurity among children, an especially acute and severe form of deprivation. In this article, I use data from the Fragile Families and Child Wellbeing Study, a cohort of children born to mostly unmarried mothers, to examine the relationship between paternal incarceration and three indicators of food insecurity among young children: current food insecurity (at age five), onset of food insecurity (between ages three and five), and exit from food insecurity …

Income, Program Participation, Poverty, And Financial Vulnerability: Research And Data Needs, James P. Ziliak

University of Kentucky Center for Poverty Research Discussion Paper Series

The aim of this paper is to assess the adequacy of the data infrastructure in the United States to meet future research and policy evaluation needs as it pertains to income, program participation, poverty, and financial vulnerability. I first discuss some major research themes that are likely to dominate policy and scientific discussions in the coming decade. This list includes research on the long-term consequences of income inequality and mobility, issues of transfer-program participation and intergenerational dependence, challenges with poverty measurement and poverty persistence, and material deprivation. I then summarize what information we currently collect in the U.S. that is …

Effects Of Maternal Depression On Family Food Insecurity, Kelly Noonan, Hope Corman, Nancy E. Reichman

University of Kentucky Center for Poverty Research Discussion Paper Series

Theory suggests that adverse life events—such as unemployment or health shocks—can result in food insecurity, which has increased substantially in the U.S. over the past decade alongside the obesity epidemic. We test this proposition by estimating the effects of a specific and salient mental health event—maternal depression during the postpartum year—on child and family food insecurity. Using data from the Early Childhood Longitudinal Study—Birth Cohort, we estimate the effects of maternal depression on food insecurity using both single- and twostage models, and explore potential buffering effects of relevant public assistance programs and supports. We find that moderate to severe maternal …

The Role Of Cps Nonresponse On The Level And Trend In Poverty, Charles Hokayem, Christopher R. Bollinger, James P. Ziliak

University of Kentucky Center for Poverty Research Discussion Paper Series

The Current Population Survey Annual Social and Economic Supplement (ASEC) serves as the data source for official income, poverty, and inequality statistics in the United States. There is a concern that the rise in nonresponse to earnings questions could deteriorate data quality and distort estimates of these important metrics. We use a dataset of internal ASEC records matched to Social Security Detailed Earnings Records (DER) to study the impact of earnings nonresponse on estimates of poverty from 1997-2008. Our analysis does not treat the administrative data as the “truth”; instead, we rely on information from both administrative and survey data. …

Snap And Food Consumption, Hilary W. Hoynes, Leslie Mcgranahan, Diane W. Schanzenbach

University of Kentucky Center for Poverty Research Discussion Paper Series

In this paper we describe the relationship between SNAP and food consumption. We first present the neoclassical framework for analyzing in-kind transfers, which unambiguously predicts that SNAP will increase food consumption, and then describe the SNAP benefit formula. We then present new evidence from the Consumer Expenditure Survey on food spending patterns among households overall, SNAP recipients, and other subgroups of interest. We find that a substantial fraction of SNAP-eligible households spend an amount that is above the program’s needs standard. We also show that the relationship between family size and food spending is steeper than the slope of the …

The Health And Nutrition Effects Of Snap: Selection Into The Program And A Review Of The Literature On Its Effects, Marianne Bitler

University of Kentucky Center for Poverty Research Discussion Paper Series

The goal of this paper is to assess the existing state of knowledge about whether SNAP improves health and nutrition outcomes, and if so, which ones and by how much.

In an era of fiscal crisis, knowing whether SNAP has any significant causal effect on health and nutrition is crucial for informing policy decisions and policy makers. In this review, I pay particular attention to the challenges researchers face in overcoming selection bias and identifying causal effects of the program, and I will assess the literature through that lens. The fundamental challenge in program evaluation in general and in assessing …

The Supplemental Nutrition Assistance Program And Food Insecurity, Christian Gregory, Matthew P. Rabbitt, David C. Ribar

University of Kentucky Center for Poverty Research Discussion Paper Series

This chapter reviews recent theory and empirical evidence regarding the effect of SNAP on food insecurity and replicates the modelling strategies used in the empirical literature. The authors find that recent evidence suggesting an ameliorative effect of SNAP on food insecurity may not be robust to specification choice or data. Most specifications mirror the existing literature in finding a positive association of food insecurity with SNAP participation. Two-stage least squares and control function methods do show that SNAP reduces food insecurity, but effects are not consistent across sub-populations and are not always statistically significant.

Food Insecurity During Childhood: Understanding Persistence And Change Using Linked Current Population Survey Data, Sheela Kennedy, Catherine A. Fitch, John Robert Warren, Julia A. Rivera Drew

University of Kentucky Center for Poverty Research Discussion Paper Series

Our paper examines the prevalence and determinants of children’s transitions into and out of food insecurity since 2001. We use longitudinally linked data from the Food Security Supplements to the Current Population Surveys to estimate one-year transition probabilities of entry and exit from food insecurity. Our results indicate that child hunger is typically short-lived, but children experiencing very low food security frequently experience multiple consecutive years of food insecurity. We demonstrate large demographic and socioeconomic differences in rates of entry into very low food security and persistence in children's food insecurity. Income and employment shocks are important predictors of child …

The Effect Of Household Financial, Time And Environmental Constraints On Very Low Food Security Among Children, Helen H. Jensen, Oleksandr Zhylyevskyy

University of Kentucky Center for Poverty Research Discussion Paper Series

Food insecurity is detrimental to children’s well-being. A better understanding of factors contributing to low and very low food security among children in the United States can guide the design of food assistance programs. We analyze the effects of household characteristics and local food environment attributes, including food prices and availability of food stores and eating places, on children’s food insecurity. We also investigate the effects of these characteristics and attributes on food preparation time. Using Becker’s household production approach, we propose an economic model that formalizes the use of constrained financial and time resources in the household. The model …

Multigenerational Families And Food Insecurity, James P. Ziliak, Craig Gundersen

University of Kentucky Center for Poverty Research Discussion Paper Series

The prevalence of multigenerational families is on the rise in the United States, as is food insecurity. We estimate the effect of resident grandchildren on the risk of and transitions in food insecurity using repeated cross sections and longitudinally linked two-year panels of the Current Population Survey from 2001-2010. We find that rates of food insecurity in families with a grandchild present are at least twice as high in a typical year compared to families without a resident grandchild, and the extent of very low food security increased substantially faster among these households over the past decade. The rise in …

The Effect Of Safety Net Programs On Food Insecurity, Lucie Schmidt, Lara Shore-Sheppard, Tara Watson

University of Kentucky Center for Poverty Research Discussion Paper Series

Does the safety net reduce food insecurity in families? In this paper we investigate how the structure of benefits for five major safety net programs – TANF, SSI, EITC, SNAP, and Medicaid – affects low food security in families and very low food security among children. We build a calculator for the years 2001-2009 to impute eligibility and benefits for these programs in each state, taking into account cross-program eligibility rules. To identify a causal effect of the safety net, we instrument for imputed eligibility and benefits using simulated eligibility and benefits for a nationally representative sample. Focusing on non-immigrant, …

Family Structure, Work Patterns And Time Allocations: Potential Mechanisms Of Food Insecurity Among Children, Kelly Balistreri

University of Kentucky Center for Poverty Research Discussion Paper Series

Over 469 thousand households in the U.S. experienced very low food security among children, a severe condition characterized by reductions in food intake due to an inability to afford enough food. But food insecurity is not simply about economic resources. There exists a paradox in which some poor households with children are food secure while some non-poor households with children are food insecure. This study moves beyond a singular focus on income and considers how the family context may protect or generate risk of food insecurity for children. The goals of the proposed project were to: 1) to provide a …

Two Can Live As Cheaply As One...But Three’S A Crowd, Christopher Bollinger, Cheti Nicoletti, Stephen Pudney

University of Kentucky Center for Poverty Research Discussion Paper Series

To measure poverty, incomes must be equivalized across households with different structures. In this paper, we use a very flexible ordered response model to analyze the relationship between income, demographic structure and subjective assessments of financial wellbeing drawn from the 1991-2008 British Household Panel Survey. Our results suggest the existence of large scale economies within marital/cohabiting couples, but substantial diseconomies from the addition of children or further adults. This pattern contrasts sharply with commonly-used equivalence scales, and is consistent with explanations in terms of the capital requirements associated with additions to the core couple.

Is Earnings Nonresponse Ignorable?, Christopher R. Bollinger, Barry T. Hirsch

University of Kentucky Center for Poverty Research Discussion Paper Series

Earnings nonresponse in the Current Population Survey is roughly 30% in the monthly surveys and 20% in the March survey. If nonresponse is ignorable, unbiased estimates can be achieved by omitting nonrespondents. Little is known about whether CPS nonresponse is ignorable. Using sample frame measures to identify selection, we find clear-cut evidence among men but limited evidence among women for negative selection into response. Wage equation slope coefficients are affected little by selection but because of intercept shifts, wages for men and to a lesser extent women are understated, as are gender gaps. Selection is least severe among household heads.

The Child And Adult Care Food Program And Food Insecurity, Colleen Heflin, Irma Arteaga, Sara Gable

University of Kentucky Center for Poverty Research Discussion Paper Series

High rates of food insecurity are a significant problem in the United States. It is currently estimated that more than 48.8 million people live in food insecure households, meaning that at some time during the previous year, they were unable to acquire or were uncertain of having enough food to meet basic needs due to inadequate household resources (Coleman-Jensen, Nord, Andrews, & Carlson, 2011). Rates of food insecurity are substantially higher among those in households with incomes below the poverty line (40.2%) and in households with children headed by a single woman (35.1%). Levels of food insecurity increased across U.S. …

Childhood Income Volatility And Adult Outcomes, Bradley Hardy

University of Kentucky Center for Poverty Research Discussion Paper Series

Using data linked across generations in the Panel Study of Income Dynamics, I estimate the relationship between exposure to volatile income during childhood and a set of socioeconomic outcomes in adulthood. The empirical framework is an augmented intergenerational income mobility model that includes controls for income volatility. I measure income volatility at the family level in two ways. First, instability as measured by squared deviations around a family-specific mean, and then as percent changes of 25 percent or more. Volatility enters the model both separately and interacted with income level. I find that family income instability during childhood has a …

Decomposing Trends In Income Volatility: The ‘Wild Ride’ At The Top And Bottom, Bradley Hardy, James P. Ziliak

University of Kentucky Center for Poverty Research Discussion Paper Series

We provide a detailed accounting of the trend increase in family income volatility in recent decades by quantifying the contributions of household head earnings, spouse earnings, non-transfer non-labor income, transfer income, and tax payments (inclusive of the refundable Earned Income Tax Credit), along with covariances among the income components. Using twoyear matched panels in the Current Population Survey from 1980 to 2009, we find that the volatility of family income, as measured by the variance of the arc percent change, doubled over the past three decades. The increase in volatility was most pronounced among the top 1% of the income …

Low Income Preschoolers' Non-Parental Care Experiences And Household Food Insecurity, Colleen Heflin, Irma Arteaga, Sara Gable

University of Kentucky Center for Poverty Research Discussion Paper Series

Rates of food insecurity in households with children have significantly increased over the past decade. The majority of children, including those at risk for food insecurity, participate in some form of non-parental child care during the preschool years. To evaluate the relationship between the two phenomenon, this study investigates the effects of child care arrangements on food insecurity in households with children. To address the selection bias problem that arises from the fact that enrollment in different types of child care is not a random process, this study uses propensity scores techniques. The authors compare outcomes across five child care …

Families With Hungry Children And The Transition From Preschool To Kindergarten, Colleen Heflin, Irma Arteaga, Sara Gable

University of Kentucky Center for Poverty Research Discussion Paper Series

This paper exploits a source of variation in the eligibility for federal nutrition programs to identify the program effects on food insecurity. Children are eligible for the WIC program until the day before they turn 61 months old. The result is an age discontinuity in program participation at the 61-month cutoff. Using the Early Childhood Longitudinal Study Birth-cohort dataset, we find strong evidence of a sizeable increase in household food insecurity at the 61- month cutoff. Our findings are robust to different model specifications, datasets, and various bandwidth choices using various non-parametric estimations.

Recent Developments In Antipoverty Policies In The United States, James P. Ziliak

University of Kentucky Center for Poverty Research Discussion Paper Series

I survey recent developments in antipoverty policy in the United States over the past decade and examine how the safety net and tax system affects poverty and its correlates using data from the 2000 to 2010 waves of the Current Population Survey-Annual Social and Economic Supplement. Unlike the 1980s and 1990s, and until the health care overhaul in 2009, the first decade of the 21st Century was relatively tepid in terms of major transfer policy reforms. However, real spending on most major social program increased significantly, and in some cases doubled or tripled, in response to demographic shifts and the …

Earnings Volatility In America: Evidence From Matched Cps, James P. Ziliak, Bradley Hardy, Christopher Bollinger

University of Kentucky Center for Poverty Research Discussion Paper Series

We offer new evidence on earnings volatility of men and women in the United States over the past four decades by using matched data from the March Current Population Survey. We construct a measure of total volatility that encompasses both permanent and transitory instability, and that admits employment transitions and losses from self employment. We also present a detailed decomposition of earnings volatility to account for changing shares in employment probabilities, conditional variances of continuous workers, and conditional mean variances from labor-force entry and exit. Our results show that earnings volatility among men increased by 15 percent from the early …
