Two branches of economics
Economics is commonly divided into two main branches: microeconomics and macroeconomics. Both are important, and both are linked to each other.
Microeconomics
Microeconomics studies the behaviour of individual consumers, workers and firms and how they interact in specific markets. It analyses how prices are determined, how resources are allocated through the price mechanism, and how market structures such as perfect competition and monopoly affect outcomes.
Macroeconomics
Macroeconomics examines the economy as a whole. It looks at aggregates such as national income, inflation, unemployment and economic growth and studies how government policies influence these variables.
Both microeconomics and macroeconomics are interrelated. Aggregate demand and supply in the macroeconomy are built on individual decisions by households and firms, while macroeconomic conditions such as interest rates and inflation influence microeconomic decisions.
| Aspect | Microeconomics | Macroeconomics |
|---|---|---|
| Focus | Individual markets (e.g. labour, goods) | Whole economy |
| Key variables | Price, quantity, costs, revenue | GDP, inflation, unemployment, exchange rates |
| Policy tools | Taxes/subsidies on specific goods, regulation | Fiscal policy, monetary policy, supply-side policy |
| Examples of analysis | Demand and supply of smartphones, wage determination in the labour market | Causes of economic growth, impact of inflation, causes of unemployment |
Easy examples
If you study the price of bread in one market, that is microeconomics. If you study inflation in the whole country, that is macroeconomics.
Understanding both microeconomics and macroeconomics is essential for interpreting real-world events. For example, a rise in unemployment (macroeconomics) may affect demand in the market for cars (microeconomics), while a sharp increase in oil prices (microeconomics) can contribute to inflation at the national level (macroeconomics).
