Poverty and inequality

Poverty and inequality are central concerns in economics, examining the distribution of income and wealth within and between countries. This topic explores how poverty is measured (absolute vs. relative), the causes of inequality (e.g., globalisation, labour market changes, tax policies), and the consequences for economic growth, social stability, and individual welfare. In the Edexcel A-Level Economics specification, this topic appears in both Theme 2 (Macroeconomics) and Theme 4 (Global Economics), linking to issues like economic development, fiscal policy, and market failure.

Understanding poverty and inequality is crucial because they affect economic efficiency and social justice. High inequality can lead to underinvestment in human capital, reduced social mobility, and political instability. Conversely, some inequality may incentivise effort and innovation. Students must grasp key concepts such as the Lorenz curve, Gini coefficient, and the poverty trap, as well as evaluate policies like progressive taxation, minimum wages, and welfare benefits. This topic also connects to broader debates about the role of government and the trade-off between equity and efficiency.

In the UK context, students should be aware of trends in income and wealth inequality since the 1970s, the impact of austerity, and the effects of COVID-19. Globally, they should understand how globalisation and trade have lifted millions out of poverty but also contributed to rising inequality within some countries. Mastery of this topic requires critical evaluation of data sources and policy effectiveness, making it a rich area for essay questions and data response.
