What countries have a market economy?

Most of the countries today have a combination of market economy and command economy. There are no countries that pure market economy or pure command economy. Even countries like USA, leading in their support for market economy have many laws such as anti-monopoly laws that restrict free competition, which is essential for a pure market economy. Recent bailout package by US Government have further highlighted the presence and need for command economy like action of government in all economies.

However, we can say in that communistic countries like China follow predominantly command economy, whereas democratic countries - which includes most of the countries in the world today - follow predominantly the market economy pattern.
