The great characteristic of a centralized economy is that all economic activities are directed or planned by a central authority so that the people are subjected to a hierarchical control. Every man has a superior whom he must obey. The most outstanding examples of the centralized economy are:
Command economy. A command economy, or a planned economy, is where the big decisions are made at the centre by the government. In an economic system the main decisions are, for example, allocating resources like labour, capital and oil. Prices, too, are controlled. In a command economy, these decisions are taken by a central body, usually the government. This system contrasts that of a market economy where all the economic actors involved take decisions. The benefit of a planned economy is that the planning body has (supposedly) perfect information, and can make a better decision than in the market economy.
