Adam`s Smith invisible hand(of the market)

The invisible hand of the market is a metaphor used by Adam Smith in his book Inquiry into the Nature and Causes of the Wealth of Nations (1776).  Smith tried to describe the mechanism characteristic of capitalist economies, and in the sense that the actions of individuals, due to their selfish desire to satisfy their own needs, in fact also contribute to the realization of social needs. According to Smith the market mechanism is able to regulate the process of meeting social needs and therefore rejects the need for state intervention and protectionism, as conditions for the realization of public interest.
