What countries have a market economy?

A free
market, or market, economy is one which allows the market to do as it pleases and essentially
lets the science of economics dictate how business perform. A market economy was much more
common a century or two ago, before government regulations began influencing the way market
economies were run. In America, for instance, government regulation prevents monopolies,
exploitation, and more in order to create a more equitable economy. However, there are still
several free markets in existence.

For example, nations such as Hong Kong,
Singapore, New Zealand, Australia, and Switzerland are all relatively free markets. Other
nations either have more government regulation or are based on entirely different principles
(socialist, dictatorship, etc). The above five nations, however, are the most intrinsically free
market economies in the world.
