Government policies to redistribute income include taxation and welfare benefits. These policies aim to reduce inequality but involve trade-offs between equity and economic efficiency.
The distribution of income and wealth examines how the total income and wealth of a nation are shared among its population. Income refers to the flow of earnings from factors of production (wages, rent, interest, profit), while wealth is the stock of assets owned at a point in time (property, shares, savings). Understanding this distribution is crucial because it affects social stability, economic efficiency, and policy decisions. In the CCEA A-Level Economics syllabus, this topic explores the causes and consequences of inequality, as well as government policies to redistribute resources.
Inequality is measured using tools like the Lorenz curve and the Gini coefficient. The Lorenz curve plots cumulative income share against cumulative population share, while the Gini coefficient quantifies inequality on a scale from 0 (perfect equality) to 1 (perfect inequality). The UK has experienced rising income inequality since the 1980s, driven by factors such as globalisation, technological change, and tax reforms. Wealth inequality is even more pronounced, with the top 10% owning nearly half of all wealth. This topic connects to broader themes in macroeconomics, including fiscal policy, labour markets, and economic growth.
For A-Level students, mastering this topic requires understanding both theoretical concepts and real-world applications. You should be able to explain how market forces (e.g., supply and demand for labour) and government interventions (e.g., progressive taxation, welfare benefits) shape the distribution. Additionally, evaluating the trade-offs between equity and efficiency is a key skill. For example, higher taxes on the rich may reduce inequality but could also discourage work and investment. This topic is frequently tested in essay questions, where you must use data and examples to support your arguments.
