Natural monopolies and the reason to exist in the free market system
Explanation:
In a natural monopoly when a market can supply goods or the cost of the goods can be lowered in competition with the potential competitor then it is called as natural monopoly. In a market when the first supplier of the product is demanding more cost or raises the costs of the product then it eventually rises to natural monopoly.
