Explanation

A free market is a system designed to have little or zero governmental control.

Here individuals have right to make economic decisions with no pressure.

The cost of goods is decided by the market and the consumers with no intervention from the government.

In reality, free markets don't exist. But the markets are measured by the degree of freedom.

This market will not provoke competition as it is a flexible one.

So, what makes free-market decisions to confirm is the self-interest put on to it by the consumers and dealers.
