Market Theories and Regulation : Why Do Markets and Governments Fail?

As a rule regulation, inspired by neoclassical economics, is a response to market failures, which are in disagreement with the ideal of a competitive market, especially in the sectors of public goods.

The answer to this question involves a deep conceptual discussion on markets and competition.
