Government Policies to Reduce Income Inequality

Market dynamics of skilled vs unskilled labor

  • Globalization and foreign trade expand opportunities for high-skilled workers to sell services internationally, raising demand for high-skilled labor
  • Lower-skilled workers face a larger global supply, increasing competition and potentially reducing wages in lower quintiles
  • View of high-skilled labor market:
    • Supply-side effects: additional education and on-the-job training tend to increase high-skilled labor supply and lower relative wages
    • Demand-side effects: new technology and globalization increase demand for high-skilled labor and raise relative wages
    • Result: greater inequality when demand for skilled labor grows faster than supply; if lower-skilled supply exceeds demand, lower quintile wages may fall
  • Overall implication: the combination of these forces can widen income disparity between high-skilled and low-skilled workers

Wealth vs income inequality; measurement and data

  • Key distinction:
    • Income: flow of money received over a period (e.g., per year)
    • Wealth: stock of value of assets minus debts accumulated over time
  • Wealth components include: money in bank, financial investments, pension funds, home value
  • Debts subtracted when calculating wealth (e.g., mortgages, credit card debt)
  • Wealth inequality tends to be greater than income inequality because differences in income compound into wealth over time
  • Measurement tools:
    • Quintile (or other percentile) distributions can be applied to both income and wealth
    • The Federal Reserve's Survey of Consumer Finances (SCF) is published every three years and reports data on wealth
  • Economic role of inequality measures:
    • Economists use income/wealth distributions to discuss policy options and tradeoffs, not to dictate a single ‘right’ level of inequality

Three main policy tools to reduce inequality (redistribution, opportunity, inheritance policy)

  • Redistribution: moving income from higher-income to lower-income groups
    • Public programs historically used to support poverty reduction include:
    • TANF (Temporary Assistance for Needy Families)
    • EITC (Earned Income Tax Credit)
    • SNAP (Supplemental Nutrition Assistance Program)
    • Medicaid
    • Progressive taxation funds these programs
    • Tax data example (2018 household returns):
    • Top 1%: average pre-tax income ≈ 1{,}679{,}000 per year; average federal tax rate ≈ 25.4\%
    • Top 1%: effective tax rate ≈ 20.4\%
    • Bottom two quintiles: negative effective income tax due to credits like the EITC
    • The presence of redistribution through taxes and antipoverty programs does not itself resolve how much redistribution is appropriate; tradeoffs remain
  • Ladder of Opportunity (public policy to expand equal opportunity)
    • Idea: create a broad ladder of opportunities so that all children have a reasonable path to economic success based on interests and efforts, not merely family background
    • Public policy initiatives (illustrative categories, Table 15.8):
    • Children:
      • Improved day care
      • Enrichment programs for preschoolers
      • Improved public schools
      • After-school and community activities
    • College level:
      • Widespread loans and grants for those in financial need
      • Opportunities for retraining and acquiring new skills
      • Internships and apprenticeships
      • Public support for a range of institutions from two-year community colleges to large research universities
    • Adults:
      • Opportunities for retraining and acquiring new skills
      • Internships and apprenticeships (continued or expanded)
    • Rationale: a more accessible ladder of opportunity can reduce the transmission of inequality across generations
  • Inheritance and estate taxation
    • Debate: should wealth transfer across generations be limited by taxation, or should family wealth be preserved to reward savings and entrepreneurship?
    • United States position: estate tax exists but high exemptions limit reach
    • 2022 estate tax threshold (exemption) ≈ 12{,}060{,}000
    • Implication: only a tiny share of households pays the estate tax; the tax targets very high levels of wealth
    • Public policy question: how much inheritance should be taxed to reduce intergenerational perpetuation of wealth without discouraging saving and risk-taking?

Tradeoff between incentives and income equality

  • Core idea: policies to reduce poverty or inequality can dampen incentives for work and entrepreneurship if taken too far
  • Poverty trap concept: guaranteeing a minimum income could reduce the incentive to work
  • Traditional view (Figure 15.10(a)): a higher emphasis on equality tends to come at the cost of lower economic output
    • As equality rises from point A to B, economic output typically falls
  • Alternative view (Figure 15.10(b)): there are policy designs that can increase both equality and output
    • Example: free public education provides redistribution (higher value of schooling for low-income children than their tax payments) while also expanding the skilled workforce for the future
    • In this view, equality and economic growth can be complementary, not strictly opposed
  • Practical takeaway: it is possible to design policies that improve equality with minimal harm to incentives, or even enhance incentives, by focusing on education, training, and adaptable social programs

Policy relevance beyond economics: political and social context

  • Policies to reduce inequality can sustain support for a market economy by alleviating social tensions and reducing incentives for anti-market backlash
  • Without some level of inequality reduction, popular scrutiny of market outcomes could fuel calls for restrictive interventions (e.g., price controls, protectionist measures, or other anti-market policies)
  • The Occupy movement highlighted concerns about inequality and the distribution of burdens from economic downturns (e.g., the 2008–2009 Great Recession)
  • Debate framing:
    • Pro-reduction side: reducing inequality can improve overall economic health and social cohesion; long-run higher education and training raise productivity
    • Anti-reduction side: excessive redistribution can weaken incentives and reduce economic growth

Contextual notes and real-world relevance

  • In a globalized economy, wage disparities reflect both skill-biased technological change and global competition
  • Wealth inequality often surpasses income inequality due to compounding over time and differences in asset accumulation
  • Policies that promote equal opportunities (education, training, anti-discrimination) can help reduce intergenerational poverty and support long-term growth
  • The estate tax mechanism illustrates a policy instrument aimed at limiting intergenerational wealth concentration without broadly penalizing savings or entrepreneurship

Key formulas and data to memorize

  • Effective tax rate (example data):
    ext{Effective tax rate} = rac{ ext{Total taxes paid}}{ ext{Total income}}
  • Wealth definition (stock of assets net of debts):
    ext{Wealth} = ext{Assets} - ext{Debts} = igl( ext{cash} + ext{investments} + ext{home value} + ext{other assets}igr) - ext{debts} {}
  • Wealth vs income distribution: wealth inequality tends to be greater than income inequality due to asset accumulation over time
  • Estate tax threshold (2022):
    ext{Estate tax exemption} = ext{ ext{15-yr value}} \ ext{(in 2022)}
    ightarrow 12{,}060{,}000 ext{ USD}
  • Notational references
    • TANF, EITC, SNAP, Medicaid: major poverty alleviation programs referenced
    • SCF: Survey of Consumer Finances, published every three years

Notes on interpretation and exam readiness

  • Understand the dynamics of supply and demand in the high-skilled vs low-skilled labor markets and how globalization and technology influence wages
  • Be able to explain why wealth distribution can be more unequal than income distribution and how wealth is measured differently from income
  • Identify and describe the three main policy tools to reduce inequality: redistribution, ladder of opportunity, and inheritance taxation
  • Explain the tradeoff between incentives and equality, and discuss how certain policies (like universal public education) can potentially improve both equality and growth
  • Recognize the social and political dimensions of inequality debates, including the implications for market stability and social cohesion
  • Be able to cite the example data points (top 1% pre-tax income, effective tax rate, estate tax threshold) and explain what they illustrate about redistribution and policy design
