Chapter 5: Poverty, Inequality, and Development

Learning Objectives

• Understand the relationship between economic growth, income distribution, and poverty.

• Identify methods for measuring income inequality.

• Analyze the connection between poverty and social welfare.

• Describe policies to address income inequality and poverty.

Measuring Inequality

• Methods of Measurement:

  • Size distributions (quintiles, deciles).

  • Lorenz Curve:

  • Represents income distribution.

  • The more curved, the greater the inequality.

  • Gini Coefficient:

  • Ranges from 0 (perfect equality) to 1 (perfect inequality).

Measuring Absolute Poverty

• Definition: Living unable to meet basic needs (food, clothing, shelter).

• Headcount Index (H/N): Proportion of the population that is poor.

• Total Poverty Gap (TPG): Sum of income differences below the poverty line.

Relationship between Poverty and Inequality

• Kuznets' Inverted-U Hypothesis:

  • Initially, economic growth increases inequality, then decreases it.

• Factors Affecting Impact of Growth:

  • Exclusive vs inclusive growth impacts poverty and welfare differently.

Policy Options for Reducing Inequality and Poverty

• Intervention Areas:

  • Alter functional distribution.

  • Progressive taxation and asset redistribution.

• Workfare Programs: More effective than traditional welfare when they encourage skill acquisition without disincentivizing work.

Characteristics of High-Poverty Groups

• Includes rural populations, women, and ethnic minorities.

Multidimensional Poverty Index (MPI)

• Identifies poverty through deprivations in health, education, and living standards.

• Focuses on simultaneous deprivations to provide a detailed poverty view beyond just income.

Conclusion

• A combination of policies is essential to address economic inequalities and poverty effectively, including education access, taxation reforms, and capability-building programs.
