6. General Equilibrium with Production
A nice cite: "...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 the society that it was no part of it. By pursuing his own interest he frequently promotes that of the society more effectually than when he really intends to promote it." Adam Smith, The Wealth of Nations, B.IV, Ch. 2.
