Topic Synopsis
This topic covers the concept of income distribution, distinguishing between income and wealth, and evaluating the causes and consequences of inequalities in their distribution within an economy.
Key Concepts & Core Principles
- Income vs wealth: Income is a flow of earnings (wages, profits, benefits); wealth is a stock of assets (property, savings, shares). Inequality can exist in both.
- Lorenz curve and Gini coefficient: The Lorenz curve plots cumulative income against population; the Gini coefficient (0 = perfect equality, 1 = perfect inequality) summarises inequality from the curve.
- Causes of inequality: Differences in skills, education, inheritance, discrimination, globalisation, and technological change can widen income gaps.
- Progressive, proportional, and regressive taxes: Progressive taxes (e.g., income tax) take a higher % from high incomes; regressive taxes (e.g., VAT) take a higher % from low incomes; proportional taxes take a constant %.
- Redistribution policies: Welfare benefits (Universal Credit), minimum wage, progressive taxation, and public services (NHS, education) aim to reduce inequality.
Exam Tips & Revision Strategies
- Ensure you can clearly define and differentiate between income (a flow) and wealth (a stock).
- Be prepared to use quantitative skills to calculate income and wealth figures provided in data.
- When evaluating consequences, consider impacts on both individuals and the wider economy.
