Summary
Addressing income and wealth inequality involves understanding the difference between income as a flow concept and wealth as a stock concept, measuring inequality using the Gini coefficient, and implementing policies to redistribute income and wealth.
- Income — Represents compensation for factors of production and is considered a flow concept. Example: Wages and salaries are forms of income that fluctuate over time.
- Wealth — Accumulation of assets over time, considered a stock concept. Example: Owning property and shares contributes to an individual's wealth.
- Gini Coefficient — A numerical measure of income inequality ranging from 0 (perfect equality) to 1 (extreme inequality). Example: A Gini coefficient of 0.3 suggests a more equal income distribution than a coefficient of 0.6.
- Minimum Wage — Legally established lowest compensation employers must pay workers. Example: A minimum wage policy can increase income for workers but may lead to unemployment.
- Transfer Payments — Payments from tax revenue to specific community members without market-based production. Example: Unemployment benefits and pensions are forms of transfer payments.
- Progressive Income Taxes — Tax system where higher-income earners are taxed at higher rates. Example: A progressive tax might have rates of 20%, 40%, and 80% for different income brackets.
- State Provision of Essential Goods and Services — Government provision of goods and services to reduce inequalities. Example: Free healthcare and education provided by the state.

Key Definitions to Remember
- Income: Compensation for factors of production, considered a flow concept.
- Wealth: Accumulation of assets, considered a stock concept.
- Gini Coefficient: Measure of income inequality ranging from 0 to 1.
Common Confusions
- Confusing income with wealth; income is a flow, while wealth is a stock.
- Misunderstanding the Gini coefficient; lower values indicate more equality.
Typical Exam Questions
- What is a Gini coefficient? Answer: A measure of the extent of income inequality in a country.
- Explain the possible economic reasons for inequality of income and consider whether inequality of income can benefit an economy? Answer: Economic reasons include limited employment opportunities and underinvestment in education; inequality can incentivize innovation and investment.
- With the help of a diagram, assess whether the introduction of a minimum price in a market can be justified? Answer: Minimum price can ensure fair wages but may lead to unemployment.
What Examiners Usually Test
- Understanding of the difference between income and wealth.
- Ability to explain and calculate the Gini coefficient.
- Knowledge of policies used to address income and wealth inequality.
