Answer:
Citizens and businesses of a country, through supply and demand.
Step-by-step explanation:
A market economy is an economic system in which economic decisions and pricing of goods and services are guided solely by the total interaction of citizens and businesses in a country and there is little government intervention or central planning. This is the opposite of a centrally planned economy, in which government decisions handle many aspects of a country's economic activity.
Labor market economies in the assumption that market forces, such as supply and demand, are the best determinants of what is right for the welfare of the nation. These economies rarely participate in government interventions such as pricing, licensing fees and industry subsidizations.
