Also known as laissez-faire economies, where governments leave markets to their own devices, so the market forces of supply and demand allocate scarce resources
Firms are likely to be efficient because they have to provide goods and services demanded by consumers. They are also likely to lower their average costs and make better use of scarce resources. Therefore, overall output of the economy increases
The bureaucracy from government intervention is avoided
