A command economy is where a central government makes all economic decisions. Either the government or a collective owns the land and the means of production. It doesn't rely on the laws of supply and demand that operate in a market economy. A command economy also ignores the customs that guide a traditional economy. In recent years, many centrally-planned economies began adding aspects of the market economy. The resultant mixed economy better achieves its goals.
