Keynes — the first behavioural economist

To-day, in many parts of the world, it is the serious embarrassment of the banks which is the cause of our gravest concern …

[The banks] stand between the real borrower and the real lender. They have given their guarantee to the real lender; and this guarantee is only good if the money value of the asset belonging to the real borrower is worth the money which has been advanced on it.

It is for this reason that a decline in money values so severe as that which we are now experiencing threatens the solidity of the whole financial structure. Banks and bankers are by nature blind. They have not seen what was coming. Some of them … employ so-called “economists” who tell us even to-day that our troubles are due to the fact that the prices of some commodities and some services have not yet fallen enough, regardless of what should be the obvious fact that their cure, if it could be realised, would be a menace to the solvency of their institution. A “sound” banker, alas! is not one who foresees danger and avoids it, but one who, when he is ruined, is ruined in a conventional and orthodox way along with his fellows, so that no one can really blame him.

But to-day they are beginning at last to take notice. In many countries bankers are becoming unpleasantly aware of the fact that, when their customers’ margins have run off, they are themselves “on margin” …

The present signs suggest that the bankers of the world are bent on suicide. At every stage they have been unwilling to adopt a sufficiently drastic remedy. And by now matters have been allowed to go so far that it has become extraordinarily difficult to find any way out.

It is necessarily part of the business of a banker to maintain appearances and to profess a conventional respectability which is more than human. Lifelong practices of this kind make them the most romantic and the least realistic of men. It is so much their stock-in-trade that their position should not be questioned, that they do not even question it themselves until it is too late. Like the honest citizens they are, they feel a proper indignation at the perils of the wicked world in which they live,—when the perils mature; but they do not foresee them. A Bankers’ Conspiracy! The idea is absurd! I only wish there were one! So, if they are saved, it will be, I expect, in their own despite.

John Maynard Keynes, Essays in Persuasion, 1931



  1. At times there is verbosity, pomposity, hubris, even arrogance. But at most times there is clarity and perspicacity. I could read Keynes all day long.

  2. “The ignorance of even the best-informed investor about the more remote future is much greater than his knowledge, and he cannot but be influenced to a degree which would seem wildly disproportionate to anyone who really knew the future, and be forced to seek a clue mainly here to trends further ahead. But if this is true of the best-informed, the vast majority of those who are concerned with the buying and selling of securities know almost nothing whatever about what they are doing. They do not possess even the rudiments of what is required for a valid judgement, and are the prey of hopes and fears easily aroused by transient events and as easily dispelled. A Treatise on Money, Volume II (1930), pp. 360–61”
