Invisible Hand
In economics, Invisible hand means a self regulating behavior of the market place , This term was coined by Sir Adam Smith in his book "An Inquiry Into The Nature And Causes Of Wealth Of Nations" in the year 1776.
It basically states that
"Every individual
necessarily labours to render the annual revenue of the society as great as he
can. He generally neither intends to promote the public interest, nor knows how
much he is promoting it ... He intends only his own gain, and he is in this, as
in many other cases, led by an invisible hand to promote an end which was no
part of his intention. Nor is it always the worse for society that it was no
part of his intention. By pursuing his own interest he frequently promotes that
of the society more effectually than when he really intends to promote it. I
have never known much good done by those who affected to trade for the public
good."
