How does the economy work?
An economy works through the constant exchange of goods, services, and money among people, businesses, and governments. One person's spending is another's income, so these flows loop continuously — and prices, set by supply and demand, guide what gets produced and consumed.
See it in motion.
Watch a 2-minute animated lesson that shows exactly how the economy works.
Step by step
- 1An economy is the system of producing, exchanging, and consuming goods and services.
- 2Money flows in a loop: households spend, businesses earn and pay wages, and the cycle repeats.
- 3Prices are set by supply and demand, signalling what to produce more or less of.
- 4Governments and central banks influence it through spending, taxes, and interest rates.
- 5Growth (more output over time) is often measured by GDP; inflation tracks rising prices.
Frequently asked questions
- What makes an economy grow?
- Producing more goods and services over time — driven by more workers, better technology, investment, and productivity. Growth is commonly measured as a rise in GDP.
- What is supply and demand's role?
- They set prices. When demand exceeds supply, prices rise; when supply exceeds demand, prices fall. These signals guide how resources are allocated across the economy.
- How do governments influence the economy?
- Through fiscal policy (spending and taxes) and, via central banks, monetary policy (interest rates and the money supply) to encourage growth or cool inflation.
