"The net effect of increasing scale, centralization of capital, vertical integration and diversification within the corporate form of enterprise has been to replace the invisible hand of the market by the visible hand of the managers."
The invisible hand is a metaphor inspired by the Scottish economist and moral philosopher Adam Smith that describes the incentives which free markets sometimes create for self-interested people to accidentally act in the public interest, even when this is not something they intended. Smith originally mentioned the term in two specific, but different, economic examples. It is used once in his Theor
"To understand the economy then is to comprehend how it is driven by the animal spirits. Just as Adam Smith’s invisible hand is the keynote of classical economics, Keynes’ animal spirits are the keynote to a different view of the economy — a view that explains the underlying instabilities of capitalism."
"Suppose our social planner tried to choose an efficient allocation of resources on his own, instead of relying on market forces. To do so, he would need to know the value of a particular good to every potential consumer in the market and the cost of every potential producer. And he would need this information not only for this market but for every one of the many thousands of markets in the economy. The task is practically impossible, which explains why centrally planned economies never work very well. The planner’s job becomes easy, however, once he takes on a partner: Adam Smith’s invisible hand of the marketplace. The invisible hand takes all the information about buyers and sellers into account and guides everyone in the market to the best outcome as judged by the standard of economic efficiency. It is, truly, a remarkable feat. That is why economists so often advocate free markets as the best way to organize economic activity."
"[The rich] consume little more than the poor, and in spite of their natural selfishness and rapacity...they divide with the poor the produce of all their improvements. They are led by an invisible hand to make nearly the same distribution of the necessaries of life, which would have been made, had the earth been divided into equal portions among all its inhabitants, and thus without intending it, without knowing it, advance the interest of the society, and afford means to the multiplication of the species."
"Every individual necessarily labours to render the annual revenue of the society as great as he can. He generally, indeed, neither intends to promote the public interest, nor knows how much he is promoting it... he intends only his own security; and by directing that industry in such a manner as its produce may be of the greatest value, 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. ... 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."
"What Galbraith understood, and what later researchers (including this author) have proved, is that Adam Smiths "invisible hand" – the notion that the individual pursuit of maximum profit guides capitalist markets to efficiency – is so invisible because, quite often, its just not there. Unfettered markets often produce too much of some things, such as pollution, and too little of other things, such as basic research. As Bruce Greenwald and I have shown, whenever information is imperfect – that is, always – markets are inefficient; hence the need for government action."
"Honor sets all the parts of the body politic in motion, and by its very action connects them; thus each individual advances the public good, while he only thinks of promoting his own interest."
