US: EITC & Poverty Reduction

Study: The Intergenerational Transmission of Poverty and Public Assistance: Evidence from the Earned Income Tax Credit

The complex dynamics of poverty across generations are a crucial area of study for policymakers and researchers. This comprehensive analysis examines how childhood poverty influences adult economic outcomes, with a special focus on the Earned Income Tax Credit (EITC) as a key element in understanding these intergenerational patterns.

Childhood Poverty and Adult Outcomes

  • Core Question: Does experiencing poverty in childhood increase the likelihood of poverty in adulthood?
  • Key Variables: Parental education, family structure, neighborhood quality, and school standards.
  • Policy Implications: Understanding the transmission of poverty is pivotal for designing effective anti-poverty strategies.

Earned Income Tax Credit (EITC) - A Focal Point

  • Why EITC: As one of the largest anti-poverty programs, EITC offers a valuable context for investigating the intergenerational impact of social investments.
  • Historical Perspective: Significant federal and state expansions of EITC since the 1970s provide a diverse background for analysis.
  • Research Methodology: Explores the causal link between childhood exposure to EITC and adult economic outcomes using varied policy implementations across states and time.

Methodological Approach

  • Data Source: The study leverages data from the Panel Study of Income Dynamics (PSID).
  • Analytical Lens: Focuses on the relationship between childhood EITC exposure and adult outcomes like poverty, earnings, public assistance, and income mobility.

Key Findings

  • Reduction in Adult Poverty: EITC exposure in childhood correlates with a decrease in adult poverty and reliance on public assistance.
  • Increased Employment and Earnings: A significant increase in employment rates and earnings among adults exposed to EITC as children.
  • Income Mobility Enhancements: Childhood exposure to EITC shows potential in improving income mobility, especially among Black children.

Detailed Observations

  • Age of Exposure: The impact of EITC is more pronounced when exposure occurs in early childhood.
  • Racial and Gender Disparities: The study reveals varying effects across racial and gender lines, with Black children and women benefiting more.
  • Parental Influence: The effects of EITC exposure are more significant in families with certain income levels and parental educational backgrounds.
  • Variation by State: The impact of EITC differs across states due to variations in policy implementations.

Impact on Public Assistance

  • Reduction in Assistance Needs: EITC exposure leads to a decline in the need for public assistance like food stamps and TANF.
  • Underreporting Issue: Survey data, like the PSID, may underreport public assistance, potentially affecting the accuracy of these findings.

Demographic Insights

  • Gender Differences: Women show a more significant decline in the need for public assistance like WIC.
  • Racial Variations: Suggestive evidence of stronger benefits for Black children in poverty reduction and income mobility.
  • Parental Characteristics: Children from families with a certain income range and parental education level exhibit more pronounced effects.

Policy Implications

  • EITC’s Role in Poverty Alleviation: The findings bolster the argument for EITC’s effectiveness in reducing intergenerational poverty.
  • Targeted Improvements: The study highlights the need to enhance EITC’s impact on the lowest income families.

Limitations and Further Research

  • Survey Limitations: Potential underreporting in survey data like PSID needs to be considered.
  • Further Exploration Needed: More research is required to understand the nuanced impacts of EITC on different population segments in varied economic scenarios.


This analysis underscores the significant role of childhood economic conditions in shaping adult economic outcomes. The EITC emerges as a powerful tool in breaking the cycle of intergenerational poverty, though its effectiveness varies across different demographic groups. The findings call for nuanced policy approaches that address these disparities and focus on the most vulnerable segments of the population. Understanding these dynamics is crucial in the fight against poverty and in fostering equitable economic growth.
