The correct answer is Mixed Market
A Mixed Market, also known as a Mixed Economy, is an economic system where the government intervention and free enterprise coexist. In this type of system, the private property is protected and the laws of supply and demand determine prices, not the federal government. The duty of this latter, however, is to protect the people and the market to a certain extent.
Usually, the state is involved in international trade, national transportation, and military. In some countries, it also has a large role in major industries such as banking, energy production, health care, welfare, aerospace, and retirement programs. In other countries, its role may consist in creating certain guidelines to direct the economy.
