What are the disadvanteges and advantages of a command economy and a market economy?

[Meg]

Market economies are more efficient . You only have to look at the state of communist countries to know this. Governments can provide for public goods, social and income inequality can be substantially reduce in a market economies thru taxation and welfare (for example Sweden or Norway). The advantages of a command economy are really hard to see. The military works like a command economy. In a country totally mobilized for war or to confront a national disaster, a command economy might work better because of free rider problems inherit in all consumption under such circumstances.
