Mixed economic system
Markets do most of the work, and the government steps in where they fail — with price limits, taxes, subsidies, rules, or by providing goods itself. Each tool changes price and quantity in a predictable way.
Need to know
What you need to know
- A mixed economy combines private-sector markets with public-sector provision and intervention.
- Markets fail for public goods, merit and demerit goods, externalities and inequality — the case for intervention.
- Planning fails on incentives and information — the case for markets.
- Countries differ in the balance, and the balance shifts with governments and events.
Explanation
Mixed economic system
- Markets allocate most goods; the government intervenes where they fail.
- A maximum price below equilibrium causes a shortage; a minimum price above it causes a surplus.
- An indirect tax shifts supply left (price up); a subsidy shifts it right (price down).
- Regulation, direct provision, nationalisation and privatisation change who decides and who owns.
