Arguments Against Standard Central Bank Lender-of-Last Resort Operations:
- Since at least 1844, central banks have been trying to avoid great depressions by acting as lenders-of-last-resort in times of financial crisis
- Stage I: provide liquidity (at a penalty rate)
- Stage II: lower interest rates on safe assets (via open market operations)
- Stage III: direct market support of some kind
The critics say...
This is a very old argument indeed: Karl Marx and Friedrich Engels made it.
It is, I think, a matter of time and scale: we want investment spending to decline as rapidly as workers can be redeployed to other potential leading sectors--but no faster. The bubble needs to "deflate," not "pop"...
Paul Krugman has, I think, the best answer:
THE HANGOVER THEORY: Are Recessions the inevitable payback for good times?: A few weeks ago, a journalist devoted a substantial part of a profile of yours truly to my failure to pay due attention to the "Austrian theory" of the business cycle--a theory that I regard as being about as worthy of serious study as the phlogiston theory of fire. Oh well. But the incident set me thinking--not so much about that particular theory as about the general worldview behind it. Call it the overinvestment theory of recessions, or "liquidationism," or just call it the "hangover theory." It is the idea that slumps are the price we pay for booms, that the suffering the economy experiences during a recession is a necessary punishment for the excesses of the previous expansion.
The hangover theory is perversely seductive--not because it offers an easy way out, but because it doesn't. It turns the wiggles on our charts into a morality play, a tale of hubris and downfall. And it offers adherents the special pleasure of dispensing painful advice with a clear conscience, secure in the belief that they are not heartless but merely practicing tough love.... The many variants of the hangover theory all go something like this: In the beginning, an investment boom gets out of hand... all that investment leads to the creation of too much capacity--of factories that cannot find markets, of office buildings that cannot find tenants... reality strikes--investors go bust and investment spending collapses. The result is a slump whose depth is in proportion to the previous excesses. Moreover, that slump is part of the necessary healing process: The excess capacity gets worked off, prices and wages fall from their excessive boom levels, and only then is the economy ready to recover.
Except for that last bit about the virtues of recessions, this is not a bad story about investment cycles.... But let's ask a seemingly silly question: Why should the ups and downs of investment demand lead to ups and downs in the economy as a whole?... Here's the problem: As a matter of simple arithmetic, total spending in the economy is necessarily equal to total income (every sale is also a purchase, and vice versa). So if people decide to spend less on investment goods, doesn't that mean that they must be deciding to spend more on consumption goods--implying that an investment slump should always be accompanied by a corresponding consumption boom? And if so why should there be a rise in unemployment?
Most modern hangover theorists probably don't even realize this is a problem for their story. Nor did those supposedly deep Austrian theorists answer the riddle. The best that von Hayek or Schumpeter could come up with was the vague suggestion that unemployment was a frictional problem created as the economy transferred workers from a bloated investment goods sector back to the production of consumer goods. (Hence their opposition to any attempt to increase demand: This would leave "part of the work of depression undone," since mass unemployment was part of the process of "adapting the structure of production.") But in that case, why doesn't the investment boom--which presumably requires a transfer of workers in the opposite direction--also generate mass unemployment? And anyway, this story bears little resemblance to what actually happens in a recession, when every industry--not just the investment sector--normally contracts.... The hangover theory, then, turns out to be intellectually incoherent; nobody has managed to explain why bad investments in the past require the unemployment of good workers in the present. Yet the theory has powerful emotional appeal. Usually that appeal is strongest for conservatives.... But moderates and liberals are not immune to the theory's seductive charms--especially when it gives them a chance to lecture others on their failings...
Karl Marx and Friedrich Engels, 1848:
The bourgeoisie, during its rule of scarce one hundred years, has created more massive and more colossal productive forces than have all preceding generations together. Subjection of Nature's forces to man, machinery, application of chemistry to industry and agriculture, steam-navigation, railways, electric telegraphs, clearing of whole continents for cultivation, canalisation of rivers, whole populations conjured out of the ground - what earlier century had even a presentiment that such productive forces slumbered in the lap of social labour?...
Modern bourgeois society with its relations of production, of exchange and of property, a society that has conjured up such gigantic means of production and of exchange, is like the sorcerer, who is no longer able to control the powers of the nether world whom he has called up by his spells.... It is enough to mention the commercial crises that by their periodical return put on its trial, each time more threateningly, the existence of the entire bourgeois society. In these crises a great part not only of the existing products, but also of the previously created productive forces, are periodically destroyed. In these crises there breaks out an epidemic 10 that, in all earlier epochs, would have seemed an absurdity - the epidemic of over-production. Society suddenly finds itself put back into a state of momentary barbarism; it appears as if a famine, a universal war of devastation had cut off the supply of every means of subsistence; industry and commerce seem to be destroyed; and why? Because there is too much civilization, too much means of subsistence, too much industry, too much commerce.... The conditions of bourgeois society are too narrow to comprise the wealth created by them. And how does the bourgeoisie get over these crises? On the one hand by enforced destruction of a mass of productive forces; on the other, by the conquest of new markets, and by the more thorough exploitation of the old ones. That is to say, by paving the way for more extensive and more destructive crises, and by diminishing the means whereby crises are prevented...
Karl Marx and Friedrich Engels, 1851:
The years 1843-5 were years of industrial and commercial prosperity, a necessary sequel to the almost uninterrupted industrial depression of 1837-42. As is always the case, prosperity very rapidly encouraged speculation. Speculation regularly occurs in periods when overproduction is already in full swing. It provides overproduction with temporary market outlets, while for this very reason precipitating the outbreak of the crisis and increasing its force. The crisis itself first breaks out in the area of speculation; only later does it hit production. What appears to the superficial observer to be the cause of the crisis is not overproduction but excess speculation, but this is itself only a symptom of overproduction. The subsequent disruption of production does not appear as a consequence of its own previous exuberance but merely as a setback caused by the collapse of speculation....
In the years of prosperity from 1843 to 1845, speculation was concentrated principally in railways, where it was based upon a real demand.... The extension of the English railway system... 1845... the number of bills presented for the formation of railway companies [i.e., IPOs] amounted to 1,035.... The heyday of this speculation was the summer and autumn of 1845. Stock prices rose continuously, and the speculators' profits soon sucked all social classes into the whirlpool. Dukes and earls competed with merchants and manufacturers for the lucrative honour of sitting on the boards of directors of the various companies; members of the House of Commons, the legal profession and the clergy were also represented in large numbers. Anyone who had saved a penny, anyone who had the least credit at his disposal, speculated in railway stocks. The number of railway journals rose from three to twenty. The large daily papers often each earned £14,000 per week from railway advertisements and prospectuses. Not enough engineers could be found, and they were paid enormous salaries. Printers, lithographers, bookbinders, paper-merchants and others, who were mobilized to produce prospectuses, plans, maps, etc; furnishing manufacturers who fitted out the mushrooming offices of the countless railway boards and provisional committees — all were paid splendid sums. On the basis of the actual extension of the English and continental railway system and the speculation which accompanied it, there gradually arose in this period a superstructure of fraud.... Hundreds of companies were promoted without the least chance of success, companies whose promoters themselves never intended any real execution of the schemes, companies whose sole reason for existence was the directors' consumption of the funds deposited and the fraudulent profits obtained from the sale of stocks.
In October 1848 a reaction ensued, soon becoming a total panic.... The railway crisis lasted into the autumn of 1848, prolonged by the successive bankruptcies of less unsound schemes as they were gradually affected by the general pressure and as demands for payment were made. This crisis was also aggravated by developments in other areas of speculation, and in commerce and industry; the prices of the older, better-established stocks were gradually forced down, until in October 1848 they reached their lowest level....
If the new cycle of industrial development which began in 1848 takes the same course as that of 1843-7, the crisis will break out in 1852. As a symptom that the excess speculation which is caused by overproduction, and which precedes each crisis, will not be long in coming, we can quote the fact that the discount rate of the Bank of England has not risen above 3 per cent for two years. But when the Bank of England keeps its interest rates down in times of prosperity, the other money dealers have to reduce their rates even more, just as in times of crisis when the Bank raises the rate considerably, they have to raise their rates above the Bank's. The additional capital which, as we have seen above, is always unloaded onto the bond market in times of prosperity, is enough by itself to force down the interest rate, as a result of the laws of competition; but the interest rate is reduced to a much larger extent by the enormous expansion of credit produced by general prosperity, which lowers the demand for capital. In these periods a government is in a position to reduce the interest rate on its funded debts, and the landowner is able to renew his mortgage on more favourable terms. The capitalists with investments in loan capital thus see their income reduced by a third or more, at a time when the income of all other classes is rising. The longer this situation lasts, the more they will be under pressure to look for more profitable capital investments. Overproduction gives rise to numerous new projects, and the success of a few of them is sufficient to attract a whole mass of capital in the same direction, until gradually the bubble becomes general. But, as we have seen, speculation has at this point of time only two outlets; cotton growing and the new world market routes created by the development of California and Australia. It is evident that this time the scope for speculation will assume far greater dimensions than in any earlier period of prosperity....
Sir Robert Peel... has been apotheosized in the most exaggerated fashion by almost all parties as England's greatest statesman. One thing at least distinguished him from the European 'statesmen' — he was no mere careerist. Beyond this, the statesmanship of this son of the bourgeoisie who rose to be leader of the aristocracy consisted in the view that there is today only one real aristocracy: the bourgeoisie.... Catholic emancipation and the reform of the police, by means of which he increased the bourgeoisie's political power... the Bank Acts of 1818 and 1844, which strengthened the financial aristocracy... the tariff reform of 1842 and the free trade legislation of 1846, with which the aristocracy was nothing short of sacrificed to the industrial bourgeoisie.... His power over the House of Commons was based upon the extraordinary plausibility of his eloquence. If one reads his most famous speeches, one finds that they consist of a massive accumulation of commonplaces, skillfully interspersed with s large amount of statistical data. Almost all the towns in England want to erect a monument to the man who repealed the Corn Laws. A Chartist journal has remarked, referring to the police trained by Peel in 1829: 'What do we want with these monuments to Peel? Every police officer in England and Ireland is a living monument to Peel...

: THE HANGOVER THEORY: Are Recessions the inevitable payback for good times?
SYNOPSIS: The constantly occuring idea of helpful Recessions is incoherent and faulty
A few weeks ago, a journalist devoted a substantial part of a profile of yours truly to my failure to pay due attention to the "Austrian theory" of the business cycle--a theory that I regard as being about as worthy of serious study as the phlogiston theory of fire. Oh well. But the incident set me thinking--not so much about that particular theory as about the general worldview behind it. Call it the overinvestment theory of recessions, or "liquidationism," or just call it the "hangover theory." It is the idea that slumps are the price we pay for booms, that the suffering the economy experiences during a recession is a necessary punishment for the excesses of the previous expansion.
The hangover theory is perversely seductive--not because it offers an easy way out, but because it doesn't. It turns the wiggles on our charts into a morality play, a tale of hubris and downfall. And it offers adherents the special pleasure of dispensing painful advice with a clear conscience, secure in the belief that they are not heartless but merely practicing tough love.
Powerful as these seductions may be, they must be resisted--for the hangover theory is disastrously wrongheaded. Recessions are not necessary consequences of booms. They can and should be fought, not with austerity but with liberality--with policies that encourage people to spend more, not less. Nor is this merely an academic argument: The hangover theory can do real harm. Liquidationist views played an important role in the spread of the Great Depression--with Austrian theorists such as Friedrich von Hayek and Joseph Schumpeter strenuously arguing, in the very depths of that depression, against any attempt to restore "sham" prosperity by expanding credit and the money supply. And these same views are doing their bit to inhibit recovery in the world's depressed economies at this very moment.
The many variants of the hangover theory all go something like this: In the beginning, an investment boom gets out of hand. Maybe excessive money creation or reckless bank lending drives it, maybe it is simply a matter of irrational exuberance on the part of entrepreneurs. Whatever the reason, all that investment leads to the creation of too much capacity--of factories that cannot find markets, of office buildings that cannot find tenants. Since construction projects take time to complete, however, the boom can proceed for a while before its unsoundness becomes apparent. Eventually, however, reality strikes--investors go bust and investment spending collapses. The result is a slump whose depth is in proportion to the previous excesses. Moreover, that slump is part of the necessary healing process: The excess capacity gets worked off, prices and wages fall from their excessive boom levels, and only then is the economy ready to recover.
Except for that last bit about the virtues of recessions, this is not a bad story about investment cycles. Anyone who has watched the ups and downs of, say, Boston's real estate market over the past 20 years can tell you that episodes in which overoptimism and overbuilding are followed by a bleary-eyed morning after are very much a part of real life. But let's ask a seemingly silly question: Why should the ups and downs of investment demand lead to ups and downs in the economy as a whole? Don't say that it's obvious--although investment cycles clearly are associated with economywide recessions and recoveries in practice, a theory is supposed to explain observed correlations, not just assume them. And in fact the key to the Keynesian revolution in economic thought--a revolution that made hangover theory in general and Austrian theory in particular as obsolete as epicycles--was John Maynard Keynes' realization that the crucial question was not why investment demand sometimes declines, but why such declines cause the whole economy to slump.
Here's the problem: As a matter of simple arithmetic, total spending in the economy is necessarily equal to total income (every sale is also a purchase, and vice versa). So if people decide to spend less on investment goods, doesn't that mean that they must be deciding to spend more on consumption goods--implying that an investment slump should always be accompanied by a corresponding consumption boom? And if so why should there be a rise in unemployment?
Most modern hangover theorists probably don't even realize this is a problem for their story. Nor did those supposedly deep Austrian theorists answer the riddle. The best that von Hayek or Schumpeter could come up with was the vague suggestion that unemployment was a frictional problem created as the economy transferred workers from a bloated investment goods sector back to the production of consumer goods. (Hence their opposition to any attempt to increase demand: This would leave "part of the work of depression undone," since mass unemployment was part of the process of "adapting the structure of production.") But in that case, why doesn't the investment boom--which presumably requires a transfer of workers in the opposite direction--also generate mass unemployment? And anyway, this story bears little resemblance to what actually happens in a recession, when every industry--not just the investment sector--normally contracts.
As is so often the case in economics (or for that matter in any intellectual endeavor), the explanation of how recessions can happen, though arrived at only after an epic intellectual journey, turns out to be extremely simple. A recession happens when, for whatever reason, a large part of the private sector tries to increase its cash reserves at the same time. Yet, for all its simplicity, the insight that a slump is about an excess demand for money makes nonsense of the whole hangover theory. For if the problem is that collectively people want to hold more money than there is in circulation, why not simply increase the supply of money? You may tell me that it's not that simple, that during the previous boom businessmen made bad investments and banks made bad loans. Well, fine. Junk the bad investments and write off the bad loans. Why should this require that perfectly good productive capacity be left idle?
The hangover theory, then, turns out to be intellectually incoherent; nobody has managed to explain why bad investments in the past require the unemployment of good workers in the present. Yet the theory has powerful emotional appeal. Usually that appeal is strongest for conservatives, who can't stand the thought that positive action by governments (let alone--horrors!--printing money) can ever be a good idea. Some libertarians extol the Austrian theory, not because they have really thought that theory through, but because they feel the need for some prestigious alternative to the perceived statist implications of Keynesianism. And some people probably are attracted to Austrianism because they imagine that it devalues the intellectual pretensions of economics professors. But moderates and liberals are not immune to the theory's seductive charms--especially when it gives them a chance to lecture others on their failings.
Few Western commentators have resisted the temptation to turn Asia's economic woes into an occasion for moralizing on the region's past sins. How many articles have you read blaming Japan's current malaise on the excesses of the "bubble economy" of the 1980s--even though that bubble burst almost a decade ago? How many editorials have you seen warning that credit expansion in Korea or Malaysia is a terrible idea, because after all it was excessive credit expansion that created the problem in the first place?
And the Asians--the Japanese in particular--take such strictures seriously. One often hears that Japan is adrift because its politicians refuse to make hard choices, to take on vested interests. The truth is that the Japanese have been remarkably willing to make hard choices, such as raising taxes sharply in 1997. Indeed, they are in trouble partly because they insist on making hard choices, when what the economy really needs is to take the easy way out. The Great Depression happened largely because policy-makers imagined that austerity was the way to fight a recession; the not-so-great depression that has enveloped much of Asia has been worsened by the same instinct. Keynes had it right: Often, if not always, "it is ideas, not vested interests, that are dangerous for good or evil."
