In a market economy, private firms and consumers decide what, how and for whom through the price mechanism.
A market economic system is one where resources are allocated by the price mechanism. Private individuals and firms own most resources. Demand and supply decide what is made, how and for whom, with little government involvement.
Advantages: firms compete for customers, so they keep costs down and quality up. Consumers enjoy wide choice. The search for profit encourages new products and better methods. Prices respond quickly when wants change.
Disadvantages: income and wealth can be very unequal, because goods go to those who can pay. Some useful goods, such as street lighting, are not provided at all. Harmful goods may be over-produced.
Firms may also grow into monopolies that charge high prices. And there is little protection for people who cannot work, such as the sick or elderly.

Worked example: Using a context in an answer
A question asks for one advantage and one disadvantage of the market system for smartphones.
- Advantage: rival makers compete to add features and cut prices, so consumers get better phones over time.
- Disadvantage: the newest phones go to those who can afford them, so lower-income households may be left out.
- Link each point back to the price mechanism: competition and profit on one side, ability to pay on the other.
Watch out for this
A market economy has no government at all.
Even market economies have a government that sets laws and protects property. What makes it a market economy is that prices, not the government, mainly allocate resources.
