Topic 10 Economic Inequality - Sources and Redistribution

ECON2010 – Business Economics: Economic Inequality - Sources & Redistribution

Introduction to Economic Inequality

  • Understand global income and wealth distribution.

  • Recognize sources and trends of economic inequality.

  • Comprehend income redistribution concepts.

Global Inequality and Trends

  • Global income distribution is significantly more unequal than within any nation.

  • Key statistics:

    • 50% of the global population lives on $2.50 a day or less.

    • 30% live on $2.50 to $10 a day.

    • 80% of the world is categorized as very poor.

    • The average income of an American is $115 per day.

Sources of Economic Inequality

  • Economic inequality arises from two main factors:

    1. Unequal labor market outcomes.

    2. Unequal ownership of capital.

1. Human Capital

  • Defined as education, skills, and experience.

    • Higher human capital leads to greater income potential.

  • Globalization effects:

    • Decrease in low-skilled labor demand → Wage reductions.

    • Increase in high-skilled worker demand → Wage increases.

2. Discrimination

  • Discrimination can skew perception of marginal product across different genders or races.

  • Example:

    • Identical ability as investment advisors leads to equal remuneration, but market bias results in men earning more if there is prejudice against female advisors.

3. Contests Among Superstars

  • Large income differences cannot be solely explained by human capital.

  • Contests reward scarce resources; often only one winner.

    • Prizes are designed to incentivize high participation and performance.

4. Unequal Wealth Ownership

  • Wealth inequality exceeds income inequality due to:

    1. Life-cycle savings: Individuals save differently at various life stages.

    2. Wealth transfer across generations: Concentrates wealth within families.

  • Notable statistics:

    • 2,251,000 new millionaires in the US from 2019 to 2020.

    • Total US millionaires: 20.27 million, billionaires: 788.

    • Comparison: China has 5.3 million millionaires and 1058 billionaires.

Income Redistribution Mechanisms

  • Governments use three primary methods to redistribute income:

    1. Income Taxes:

      • Progressive tax systems impose higher rates on higher income brackets.

    2. Income Maintenance Programs:

      • Direct financial support through:

        • Social Security

        • Unemployment compensation

        • Welfare programs

    3. Subsidized Services:

      • Government-provided services at lower costs:

        • Public education (primary/secondary)

        • Healthcare, where costs to families are significantly reduced (20-25% of actual costs).

  • Emphasis on education and job training as long-term solutions to inequality issues.
