Adam Smith and his “Wealth of Nations” 1776

Adam Smith and “the Invisible Hand”

“As every individual, therefore, endeavours as much as he can … to employ his capital …He generally, indeed, 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”.

Adam Smith in the Wealth of Nations

“…[the state is responsible] for erecting and maintaining those public institutions and those public works, which though they may be in the highest degree advantageous to a great society, are, however, of such a nature, that the profit could never repay the expense to any individual or small number of individuals, and which it, therefore, cannot be expected that any individual or small number of individuals should erect or maintain.”

The Lessons Of the Past:Do Not Just Print Money!

Hyperinflation!

• By the end of 1923 the German currency was of no value at all. The quarterly rate of inflation stood at 52,000%, which is the equivalent to an annual rate of 7,000,000,000,000%.

• In 1924 the currency was replaced with a new currency

Serageldin on Reductionist Views

• A society is more than the sum of its economic and financial transactions…

Now, let us turn to the global crisis
