Answer:
Societies are generally classified as either free market systems or closed (command) economies.
Step-by-step explanation:
In a free market system, the government does little in the way of regulation of the market and companies and entrepreneurs are free to conduct business transactions and to invest as they see fit. The United States economy is the quintessential example of this model. In a command economy, it is the central government that decides what should be manufactured and what services are provided. The government would establish and control prices and also place limits and control the levels of investments and incomes. China is an example of a command economy although in recent years the government has implemented many more free-market reforms.
