Answer: Market and command economy
Explanation: A mixed economy is a combination of market and command economy.
Market economy is a characteristic of capitalist societies, where the state's influence is very small or almost nonexistent, and competition exists on the market and private entrepreneurship. Such a market is managed by the so-called "invisible hand" that represents the liberal laws of the market.
The command economy is a characteristic of communist societies and the like, though it is not always the rule that this type of economy should only be in communism. In such an economy there is a state property, the government determines the scope, type of production and services, economic relations in general.
The mixed economy, therefore, consists of both private and state property. So that private and state entities share control over the elements of the economy, production, sale, exchange of goods, services. The goal such an economy is, among other things, monitoring and controlling monopolies. Monopolies are something that suppresses and undermines competition and hence the existence of a mixed economy is sometimes necessary to prevent it.
