Topics

Everything you need to understand economics at GCSE, A-Level, and beyond.

Microeconomics

Microeconomics is the study of how individual agents — consumers, firms, and markets — make decisions. It's the foundation of economic thinking, and understanding it properly makes every other area of economics easier to grasp.

  • Supply, demand, and price determination
  • Elasticity — price, income, and cross elasticity
  • Market structures: perfect competition, monopoly, oligopoly
  • Market failure: externalities, public goods, information asymmetry

Macroeconomics

Macroeconomics looks at the economy as a whole — national output, employment, inflation, and the policy tools governments and central banks use to manage them. This is where economic theory meets real-world policy.

  • GDP, economic growth, and the business cycle
  • Inflation and deflation — causes, consequences, and measurement
  • Unemployment — types, causes, and policy responses
  • Fiscal policy and monetary policy explained

International Economics

How countries trade, why comparative advantage matters, and what happens when governments intervene in international markets. International economics connects microeconomic logic to global-scale outcomes.

  • Absolute and comparative advantage
  • Trade barriers: tariffs, quotas, and subsidies
  • Balance of payments and exchange rates
  • Globalisation — benefits, costs, and debates

Development Economics

Why are some countries rich and others poor? Development economics examines the factors that drive long-run economic growth and the policies that help (or hinder) living standards in lower-income economies.

  • Measures of development: GDP per capita, HDI, and beyond
  • Barriers to development and the poverty trap
  • Aid, trade, and foreign direct investment
  • Sustainable development and the environment
