In a market economy, producers and consumers make all the decisions. Producers decide what goods and services to offer, Consumers are free to decide how they will spend their money. The government tries not to interfere in business. Instead, it provides only the services that are necessary to ensure that the economy can work effectively. For example, a government might provide national defense, road building, policing, and fire protection, but not own and run industries. The United States and Taiwan have market economies.
