Study Notes
Measuring Inequality and Poverty
- Size Distributions: Analyze income distribution across population groups like quintiles (fifths) and deciles (tenths).
- Lorenz Curves: Illustrate income inequality visually by plotting the cumulative percentage of income against the cumulative percentage of the population. The more bowed the curve, the higher the inequality.
- Gini Coefficients: Quantify income inequality using a numerical value between 0 (perfect equality) and 1 (perfect inequality). A higher Gini coefficient indicates greater inequality.
- Functional Distributions: Examine income distribution across different factors of production, such as wages, profits, and rents.
Measuring Absolute Poverty
- Headcount Index: Measures the percentage of people living below a poverty line.
- Total Poverty Gap: Represents the total amount of income needed to raise all individuals living below the poverty line to that threshold.
-
Multidimensional Poverty Index (MPI): Offers a broader measurement of poverty by considering factors beyond income, such as education, health, and living standards.
- Dual Cutoff: Individuals are considered multidimensionally poor if they fall below certain thresholds in multiple dimensions.
- MPI Indicators: Focus on health, education, and living standards, with each area receiving equal weighting.
- Dimensional Monotonicity: The MPI recognizes that additional deprivations increase overall poverty.
Poverty, Inequality, and Social Welfare
- Dualistic Development: Describes a situation where economic progress benefits certain sectors of the population while others remain stagnant.
- Shifting Lorenz Curves: Depict how income inequality can change over time within different sectors of the economy.
- Traditional Sector Enrichment: Economic growth primarily benefits the traditional sector (e.g., agriculture), potentially leading to a decrease in income inequality.
- Modern Sector Enrichment: Economic growth primarily benefits the modern sector (e.g., industry), potentially leading to an increase in income inequality.
Absolute Poverty: Extent and Magnitude
- Progress on Extreme Poverty: There has been notable progress in reducing poverty levels, particularly for those living on $1.25 per day.
- Uneven Poverty Incidence: Poverty levels vary significantly across different regions and countries.
- Growth and Poverty Reduction: Economic growth can lead to poverty reduction, especially when it is inclusive and benefits all population groups.
- Lower Poverty and Growth: Lower levels of extreme poverty can contribute to higher economic growth.
Economic Characteristics of High-Poverty Groups
- Rural Poverty: Often experienced by a higher proportion of the population due to limited access to education, healthcare, and economic opportunities.
- Women and Poverty: Women are disproportionately affected by poverty, facing challenges such as limited control over resources, unpaid work, and discrimination.
- Ethnic Minorities and Indigenous Populations: These groups often experience higher poverty rates due to historical marginalization, discrimination, and lack of access to basic services.
Policy Options on Income Inequality and Poverty
- Altering the Functional Distribution: Aims to change the distribution of income across factors of production.
- Mitigating the Size Distribution: Focuses on reducing income disparities between individuals and households.
- Moderating the Distribution at Upper Levels: Implemented through progressive taxation and policies to prevent excessive wealth accumulation.
- Moderating the Distribution at Lower Levels: Involves transfer payments, social safety nets, and investments in human capital development to support those at the bottom of the distribution.
Policy Options on Income Inequality and Poverty
- Changing Relative Factor Prices: Policies that aim to adjust wage and profit levels to ensure more equitable returns to labor and capital.
- Progressive Redistribution of Asset Ownership: Initiatives to redistribute wealth and assets, such as land reform and affordable housing programs.
- Progressive Taxation: Tax systems that place a higher burden on higher earners.
- Transfer Payments and Public Provision of Goods and Services: Social benefits programs, such as pensions, unemployment insurance, and healthcare, aimed at supporting lower-income groups.
Summary and Conclusions
- Addressing poverty and inequality requires a multifaceted approach that combines policies targeting different economic and social dimensions.
-
Policy Recommendations:
- Policies to rectify distortions in factor prices (e.g., minimum wage laws), change distribution of assets, access to education and employment, implement progressive taxation, and directed transfer payments.
- Focus on building human and social capital of the poor, through investments in education, healthcare, and infrastructure.
- Overall, effective poverty and inequality reduction strategies must be comprehensive and address multiple aspects of the economic and social landscape.
