Also known as a planned economy, command economies are unable to efficiently allocate goods because of the knowledge problem - the central planner's inability to discern how much of a good should be produced. Shortages and surpluses are a common consequence of command economies. A free-market price system, on the other hand, signals to producers what they should be creating and in what quantities, resulting in a much more efficient allocation of goods.

There is massive support for a shift from the command economy to a more market-based system.
