No change in substance use disorders or overdose after implementation of state Earned Income Tax Credit (EITC)

BackgroundInadequate income is associated with higher likelihood of experiencing a substance use disorder (SUD). This study tests whether the earned income tax credit (EITC), which issues supplemental income for workers with children in the U.S., is associated with lower rates of SUD and fatal overdose. MethodsWe examined the effects of state-level refundable EITC presence and generosity (i.e., state EITC rate as a % of federal rate) on SUD-related outcomes (SUD prevalence and intentional and unintentional fatal overdose) using a difference-in-difference methodology, with both two-way fixed-effects models and event study plots. Several sensitivity analyses were conducted to assess the robustness of findings. Five data sources were used to create a combined state-level longitudinal dataset. ResultsWe did not find significant effects of refundable EITC presence or generosity on unintentional or intentional fatal overdose or SUD prevalence in two-way models. Event study models detected a very slight upward shift in SUD prevalence following refundable EITC implementation (not seen in sensitivity analyses) and no significant effects of EITC implementation on any of the fatal overdose outcomes. ConclusionsEvidence regarding income support programs is being highly sought by policy makers as income support programs have become increasingly popular policy levers since the start of the COVID-19 pandemic. Our study indicates EITC policies likely have no impact on SUD or overdose, however, other income support programs without family restrictions are important to investigate further.

The Impact of Social Networks on EITC Claiming Behavior

Abstract Using the Social Connectedness Index (Bailey, Cao, Kuchler, Stroebel et al., 2018) to capture county-to-county Facebook linkages, I explore how county-level earned income tax credit (EITC) claiming behavior changes when the county's out-of-state social network is exposed to a newly implemented state EITC. Having more out-of-state friends face a state EITC shifts the composition of EITC claims toward more self-employment claiming. EITC-claiming households' income distribution also shifts, moving away from the EITC region with smaller credits, toward income levels that generate the largest EITC. This mimics the direct impacts of state-level EITC policies, consistent with social networks increasing information or salience about EITC policy.

The Earned Income Tax Credit and Intimate Partner Violence.

Intimate partner violence (IPV) is a serious public health problem in the United States with adverse consequences for affected individuals and families. Recent reviews of the literature suggest that economic policies should be further investigated as part of comprehensive strategies to address IPV. The Earned Income Tax Credit (EITC) is the nation's largest anti-poverty program for working parents, and especially benefits low-income women with children, who experience an elevated risk of IPV. The EITC may prevent IPV by offering financial resources; such resources may help individuals experiencing IPV leave abusive relationships or address IPV risk factors, thereby preventing entry into abusive relationships. However, the association between EITC generosity and IPV has not been previously examined. We used state-level and individual-level datasets to examine the association between EITC generosity and IPV. Our state-level data source was the nationally representative National Crime Victimization Survey (NCVS; N = ~ 95,000 households per year). For NCVS, we used a difference-in-difference approach to investigate the relationship between state EITC generosity and IPV rates. We also used individual-level longitudinal data from the Fragile Families and Child Well-being Study (n = 13,422 person-waves). Using this cohort of US families at higher risk for IPV, we evaluated associations between estimated EITC benefits based on the mother's state of residence and number of children and self-reported IPV. In both state- and individual-level analyses, no significant association between state EITC benefits and IPV was found. Factors that may account for these null findings include program ineligibility for individuals who separate from abusive spouses. Future research efforts should more closely examine EITC policy implementation processes and the lived experience of participating in anti-poverty programs for people experiencing IPV.

The effects of state earned income tax credits on mental health and health behaviors: A quasi-experimental study.

The earned income tax credit (EITC) is the largest U.S. poverty alleviation program for families with children, and state EITC policies provide a modest supplement to the federal program. Yet there are few studies of the effects of state EITC policies on population health. We examined whether state EITC policies affect mental health and health behaviors. Participants were drawn from the 1995-2015 waves of the Panel Study of Income Dynamics, a diverse national cohort study (N=10,567). We used a quasi-experimental difference-in-differences analysis to examine the effects of state EITC programs among eligible individuals, accounting for secular trends among similar individuals in non-EITC states. Outcomes included self-reported general health, psychological distress, alcohol use, and smoking. The mean size of state EITC refunds in our sample was $265 for eligible individuals. In the overall sample, state EITC programs were not associated with any health outcomes of interest. This finding was robust to alternative specifications, and similar in subgroup analyses by gender and marital status. This study suggests that state EITC programs, which tend to provide smaller refunds than the federal program, may not be large enough to have a positive impact on mental health and health behaviors. These findings may inform policymaking related to the generosity of state EITC programs, especially as states seek to address the socioeconomic consequences of the COVID-19 pandemic.

Association of State-Level Earned Income Tax Credits With Rates of Reported Child Maltreatment, 2004-2017.

Poverty is an important predictor of child maltreatment. Social policies that strengthen the economic security of low-income families, such as the Earned Income Tax Credit (EITC), may reduce child maltreatment by impeding the pathways through which poverty leads to it. We used variations in the presence and generosity of supplementary EITCs offered at the state level and administrative child maltreatment data from the National Child Abuse and Neglect Data System (NCANDS) to examine the effect of EITC policies on state-level rates of child maltreatment from 2004 through 2017. Two-way fixed effects models indicated that a 10-percentage point increase in the generosity of refundable state EITC benefits was associated with 241 fewer reports of neglect per 100,000 children (95% Confidence Interval [CI] [-449, -33]). An increase in EITC generosity was associated with fewer reports of neglect both among children ages 0-5 (-324 per 100,000; 95% CI [-582, -65]) and children ages 6-17 (-201 per 100,000; 95% CI [-387, -15]). Findings also suggested associations between the EITC and reductions in other types of maltreatment (physical abuse, emotional abuse); however, those did not gain statistical significance. Economic support policies may reduce the risk of child maltreatment, especially neglect, and improve child wellbeing.

State earned income tax credits and suicidal behavior: A repeated cross-sectional study

Suicide is an increasingly common cause of death in the United States and recent increases in suicide rates disproportionately impact low income individuals. We sought to assess the impact of income support in the form of state earned income tax credit policies on suicide-related behaviors. This state-level study used repeated cross-sectional data from vital records and the National Survey of Drug Use and Health data representative at the state-level. The population included adults who either died by suicide or were selected for in-person NSDUH interviews between 2008 and 2018. Exposure was measured as the generosity of a refundable state earned income tax credit policy measured as a percentage of the federal policy. Outcomes assessed were suicidal ideation, suicidal planning, non-fatal suicide attempt, suicide deaths, and combined fatal and non-fatal suicide attempts. Analyses were performed between April and June 2020. A 10 percentage-point increase in the generosity of state earned income tax credit was associated with lower frequency of non-fatal suicide attempts (prevalence ratio [PR] = 0.96; 95% CI: 0.93–0.99), combined fatal and non-fatal suicide attempts (PR = 0.96; 95% CI: 0.93–0.99), and suicide deaths (PR = 0.99; 95% CI: 0.99–1.00). This translates to 4 fewer suicide attempts per 10,000 population each year. Generous state earned income tax credit policies are associated with reductions in the frequency of most severe suicidal behavior. Income support policies may be one way to reduce suicide attempts and death, especially among low-income adults.

Anti-poverty policy and health: Attributes and diffusion of state earned income tax credits across U.S. states from 1980 to 2020.

The U.S. federal Earned Income Tax Credit (EITC) is often considered the most effective antipoverty program for families in the U.S., leading to a variety of improved outcomes such as educational attainment, work incentives, economic activity, income, and health benefits for mothers, infants and children. State EITC supplements to the federal credit can significantly enhance the magnitude of this intervention. In this paper we advance EITC and health research by: 1) describing the diffusion of state EITC policies over 40 years, 2) presenting patterns in important EITC policy dimensions across space and time, and 3) disseminating a robust data set to advance future research by policy analysts and scientists. We used current public health law research methods to systematically collect, conduct textual legal analysis, and numerically code all EITC legislative changes from 1980 through 2020 in the 50 states and Washington, D.C. First, the pattern of diffusion across states and time shows initial introductions during the 1990s in the Midwest, then spreading to the Northeast, with more recent expansions in the West and South. Second, differences by state and time of important policy dimensions are evident, including size of credit and refundability. Third, state EITC benefits vary considerably by household structure. Continued research on health outcomes is warranted to capture the full range of potential beneficial effects of EITCs on family and child wellbeing. Lawyers and policy analysts can collaborate with epidemiologists and economists on other high-quality empirical studies to assess the many dimensions of policy and law that potentially affect the social determinants of health.

State Earned Income Tax Credit policies and intimate partner homicide in the USA, 1990-2016.

Economic insecurity is a risk factor for intimate partner homicide (IPH). The Earned Income Tax Credit (EITC) is the largest cash transfer programme to low-income working families in the USA. We hypothesised that EITCs could provide financial means for potential IPH victims to exit abusive relationships and establish self-sufficiency. We conducted a national, quasiexperimental study of state EITCs and IPH rates in 1990-2016 using a difference-in-differences approach. The national rate of IPH decreased from 1.9 per 100 000 adult women in 1990 to 1.3 per 100 000 in 2016. We found no statistically significant association between state EITC generosity and IPH rates (coefficient indicating change in IPH rates per 100 000 adult female years for additional 10% in amount of state EITC, measured as the percentage of federal EITC: 0.02, 95% CI -0.03 to 0.08). Financial control associated with abuse and current EITC eligibility rules may prevent potential IPH victims from accessing the EITC.

The effects of state-level earned income tax credits on suicides.

This study examines the relationship between state-level earned income tax credit (EITC) laws in the United States on suicides. Following findings in previous work showing that the EITC is associated with lower depression rates and reduced number of risky biomarkers, I estimated the effects of state EITC generosity on suicide rates. Using data for the years 1996 to 2016, a period with 74 state-level EITC policy changes, I find that introducing a high state EITC rate reduces suicide rates for adults aged 25 or above by 3.91%. The results are consistent across four different measures of EITC generosity.

Effects of changes in earned income tax credit: Time-series analyses of Washington DC.

Poverty has numerous deleterious effects on health, and the Earned Income Tax Credit (EITC) is the major policy tool used to alleviate poverty in the U.S. We evaluate effects of four distinct changes in earned income tax credit law in Washington, DC on maternal behaviors and infant outcomes. An interrupted time-series design was used with 312 monthly measures from 1990 through 2015 analyzed in 2018 (total n = 225,933 births). States with no EITC were included as the comparison group; analyses involved ARIMA modeling. Outcomes were derived from birth certificates, and included percent of live births below 2500 g, mean birth weight, mean gestation weeks, first trimester prenatal care, and maternal smoking during pregnancy. We found a pattern of significant improvements across all three infant outcome measures, with the size of the effect estimate monotonically matching the magnitude of the tax credit—ranging from a 1.9 (-2.9, -0.9) reduction in rate per 100 births of low birth weight for the smaller 10% credit, to a 4.7 (-5.4, -4.0) reduction with the 40% credit. Results for maternal smoking and prenatal care were mixed. Results suggest that earned income tax credit policies improve birth outcomes; mechanisms for this effect deserve further study.

Effects of state-level Earned Income Tax Credit laws in the U.S. on maternal health behaviors and infant health outcomes

The purpose of this paper is to investigate the effects of state-level Earned Income Tax Credit (EITC) laws in the U.S. on maternal health behaviors and infant health outcomes. Using multi-state, multi-year difference-in-differences analyses, we estimated effects of state EITC generosity on maternal health behaviors, birth weight and gestation weeks. We find little difference in maternal health behaviors associated with state-level EITC. In contrast, results for key infant health outcomes of birth weight and gestation weeks show small improvements in states with EITCs, with larger effects seen among states with more generous EITCs. Our results provide evidence for important health benefits of state-level EITC policies.

Improving population health by reducing poverty: New York’s Earned Income Tax Credit

Despite the established relationship between adverse health outcomes and low socioeconomic status, researchers rarely test the link between health improvements and poverty-alleviating economic policies. New research, however, links individual-level health improvements to the Earned Income Tax Credit (EITC), a broad-based income support policy. We build on these findings by examining whether the EITC has ecological, neighborhood-level health effects. We use a difference-in-difference analysis to measure child health outcomes in 90 low- and middle- income neighborhoods before and after the expansion of New York State and New York City’s EITC policy between 1997-2010. Our study takes advantage of the relatively exogenous source of income variation supplied by the EITC—legislative changes to EITC policy parameters. This feature minimizes the endogeneity problem in studying the relationship between income and health. Our estimates link a 15-percentage-point increase in EITC benefit rates to a 0.45 percentage-point reduction in the low birthweight rate. We do not observe any measurable link between EITC benefits and prenatal health or asthma-related pediatric hospitalization. The magnitude of the EITC’s impact on low birthweight rates suggests ecological effects, and an additional channel through which anti-poverty measures can serve as public health interventions.

In-work benefits for married couples: an ex-ante evaluation of EITC and WTC policies in Italy

Abstract This paper investigates labor supply and redistributive effects of in-work benefits for Italian married couples using a tax-benefit microsimulation model and a multi-sectoral discrete choice model of labor supply. We consider in-work benefits based on the Earned Income Tax Credit (EITC) and the Working Tax Credit (WTC) existing in the US and the UK, respectively. The standard design of these income support mechanisms is however augmented with a premium for two-earner households to avoid potential disincentive effects on secondary earners. Revenue neutral policy simulations show that our reforms may greatly improve the current Italian tax-benefit system in terms of both incentive and redistributive effects. Furthermore, neglecting sector-specific attributes of the various job opportunities may lead to overstated estimates of the policy effects. JEL classification I38; H31; H53

In-Work Benefits for Married Couples: An Ex-Ante Evaluation of EITC and WTC Policies in Italy

This paper investigates labor supply and redistributive effects of in-work benefits for Italian married couples using a tax-benefit microsimulation model and a multi-sectoral discrete choice model of labor supply. We consider two in-work benefit schemes following the key principles of the Earned Income Tax Credit (EITC) and the Working Tax Credit (WTC) existing in the US and the UK, respectively. The standard design of these in-work benefits is however augmented with a new benefit premium for two-earner households in order to overcome the well-known disincentive effects that these welfare instruments may generate on secondary earners. In simulation, the proposed in-work benefits are financed through the abolition of Italian family allowances for dependent employees and contingent workers thus ensuring tax revenue neutrality. We show that our EITC and WTC reforms have strong positive effects on labor supply of wives, weak negative effects on labor supply of husbands, and strong positive effects on equity. The EITC is more effective than the WTC in boosting employment of wives, while the WTC is more effective than the EITC in fighting poverty. In both schemes, the trade-off between labor supply incentives and redistributive effects is crucially related to the new benefit premium for two-earner households. Other things being equal, tax revenue neutrality implies that a higher value of this policy coefficient yields stronger incentive effects and weaker redistributive effects.

In-Work Benefits for Married Couples: An Ex-Ante Evaluation of EITC and WTC Policies in Italy

This paper investigates labor supply and redistributive effects of in-work benefits for Italian married couples using a tax-benefit microsimulation model and a multi-sectoral discrete choice model of labor supply. We consider in-work benefits based on the Earned Income Tax Credit (EITC) and the Working Tax Credit (WTC) existing in the US and the UK, respectively. The standard design of these income support mechanisms is however augmented with a premium for two-earner households to avoid potential disincentive effects on secondary earners. Revenue neutral policy simulations show that our reforms may greatly improve the current Italian tax-benefit system in terms of both incentive and redistributive effects. Furthermore, neglecting sector-specific attributes of the various job opportunities may lead to an oversimplified representation of the choice set that does not allow to capture some labor market transitions and thus results in attenuated labor supply responses.

Earned income tax credit policies: Impact and optimality: The Adam Smith Lecture, 2005

In this lecture I consider the impact and optimality of Earned Income Tax Policies. The policy issue addressed is the low labour market attachment and high incidence of poverty among certain groups. These policies have taken a central position in EU labour market policy debate and I focus on reforms over the last decade in the UK.

The Effects of Time Limits, the EITC, and Other Policy Changes on Welfare Use, Work, and Income among Female-Headed Families

Of all of the welfare reforms that were implemented during the 1990s, time limits may represent the single greatest break from past policy. This paper expands on what is known about this important welfare reform measure by exploiting the predictions from Grogger and Michalopoulos (2003) to estimate the effects of time limits on welfare use, employment, labor supply, earnings, and income among female-headed families. Results based on data from the March Current Population Survey suggest that time limits have had important effects on welfare use and work, accounting for about one-eighth of the decline in welfare use and about 7% of the rise in employment since 1993. They have had no significant effect on earnings or income, however. The analysis also shows that the collective effects of other reforms have had important impacts on employment and labor supply. Furthermore, it identifies the Earned Income Tax Credit (EITC) as a particularly important contributor to both the recent decrease in welfare use and t...
