What, then, are the causes of periodic depressions? Must we always remain agnostic about the causes of booms and busts? Is it really true that business cycles are rooted deep within the free-market economy, and that therefore some form of government planning is needed if we wish to keep the economy within some kind of stable bounds? Do booms and then busts just simply happen, or does one phase of the cycle flow logically from the other?
The currently fashionable attitude toward the business cycle stems, actually, from Karl Marx...
Marx concluded that business cycles were an inherent feature of the capitalist market economy. All the various current schools of economic thought, regardless of their other differences and the different causes that they attribute to the cycle, agree on this vital point: That these business cycles originate somewhere deep within the free-market economy. The market economy is to blame. Karl Marx believed that the periodic depressions would get worse and worse, until the masses would be moved to revolt and destroy the system, while the modern economists believe that the government can successfully stabilize depressions and the cycle. But all parties agree that the fault lies deep within the market economy and that if anything can save the day, it must be some form of massive government intervention.
There are, however, some critical problems in the assumption that the market economy is the culprit. For "general economic theory" teaches us that supply and demand always tend to be in equilibrium in the market and that therefore prices of products as well as of the factors that contribute to production are always tending toward some equilibrium point. Even though changes of data, which are always taking place, prevent equilibrium from ever being reached, there is nothing in the general theory of the market system that would account for regular and recurring boom-and-bust phases of the business cycle...
In the market economy, one of the most vital functions of the businessman is to be an "entrepreneur," a man who invests in productive methods, who buys equipment and hires labor to produce something which he is not sure will reap him any return...The market economy, then, is a profit-and-loss economy, in which the acumen and ability of business entrepreneurs is gauged by the profits and losses they reap. The market economy, moreover, contains a built-in mechanism, a kind of natural selection, that ensures the survival and the flourishing of the superior forecaster and the weeding-out of the inferior ones...How is it that, periodically, in times of the onset of recessions and especially in steep depressions, the business world suddenly experiences a massive cluster of severe losses?
An explanation such as "underconsumption" — a drop in total consumer spending — is not sufficient, for one thing, because what needs to be explained is why businessmen, able to forecast all manner of previous economic changes and developments, proved themselves totally and catastrophically unable to forecast this alleged drop in consumer demand. Why this sudden failure in forecasting ability?...
In particular, a theory of depression must account for the mammoth cluster of errors which appears swiftly and suddenly at a moment of economic crisis, and lingers through the depression period until recovery...Here is another fact of business cycle life that must be explained — and obviously can't be explained by such theories of depression as the popular underconsumption doctrine: That consumers aren't spending enough on consumer goods. For if insufficient spending is the culprit, then how is it that retail sales are the last and the least to fall in any depression, and that depression really hits such industries as machine tools, capital equipment, construction, and raw materials?...
Fortunately, a correct theory of depression and of the business cycle does exist, even though it is universally neglected in present-day economics...Essentially, these theorists saw that another crucial institution had developed in the mid-eighteenth century, alongside the industrial system. This was the institution of banking, with its capacity to expand credit and the money supply (first, in the form of paper money, or bank notes, and later in the form of demand deposits, or checking accounts, that are instantly redeemable in cash at the banks). It was the operations of these commercial banks which, these economists saw, held the key to the mysterious recurrent cycles of expansion and contraction, of boom and bust, that had puzzled observers since the mid-eighteenth century.
The banks, then, happily begin to expand credit, for the more they expand credit the greater will be their profits. This results in the expansion of the money supply within a country, say England. As the supply of paper and bank money in England increases, the money incomes and expenditures of Englishmen rise, and the increased money bids up prices of English goods. The result is inflation and a boom within the country. But this inflationary boom, while it proceeds on its merry way, sows the seeds of its own demise...
As this process intensifies, the banks will eventually become frightened. For the banks, after all, are obligated to redeem their liabilities in cash, and their cash is flowing out rapidly as their liabilities pile up. Hence, the banks will eventually lose their nerve, stop their credit expansion, and in order to save themselves, contract their bank loans outstanding...The bank contraction reverses the economic picture; contraction and bust follow boom...
This, then, is the meaning of the depression phase of the business cycle. Note that it is a phase that comes out of, and inevitably comes out of, the preceding expansionary boom. It is the preceding inflation that makes the depression phase necessary. We can see, for example, that the depression is the process by which the market economy adjusts, throws off the excesses and distortions of the previous inflationary boom, and reestablishes a sound economic condition. The depression is the unpleasant but necessary reaction to the distortions and excesses of the previous boom.
Why, then, does the next cycle begin? Why do business cycles tend to be recurrent and continuous? Because when the banks have pretty well recovered, and are in a sounder condition, they are then in a confident position to proceed to their natural path of bank credit expansion, and the next boom proceeds on its way, sowing the seeds for the next inevitable bust...
Banks can only expand comfortably in unison when a Central Bank exists, essentially a governmental bank, enjoying a monopoly of government business, and a privileged position imposed by government over the entire banking system. It is only when central banking got established that the banks were able to expand for any length of time and the familiar business cycle got underway in the modern world...
So now we see, at last, that the business cycle is brought about, not by any mysterious failings of the free market economy, but quite the opposite: By systematic intervention by government in the market process. Government intervention brings about bank expansion and inflation, and, when the inflation comes to an end, the subsequent depression-adjustment comes into play...
The correct and fully developed theory of the business cycle was finally discovered and set forth by the Austrian economist Ludwig von Mises, when he was a professor at the University of Vienna...
Without bank credit expansion, supply and demand tend to be equilibrated through the free price system, and no cumulative booms or busts can then develop. But then government through its central bank stimulates bank credit expansion by expanding central bank liabilities and therefore the cash reserves of all the nation's commercial banks. The banks then proceed to expand credit and hence the nation's money supply in the form of check deposits. As the Ricardians saw, this expansion of bank money drives up the prices of goods and hence causes inflation. But, Mises showed, it does something else, and something even more sinister. Bank credit expansion, by pouring new loan funds into the business world, artificially lowers the rate of interest in the economy below its free market level.
On the free and unhampered market, the interest rate is determined purely by the "time-preferences" of all the individuals that make up the market economy...The inflationary boom thus leads to distortions of the pricing and production system. Prices of labor and raw materials in the capital goods industries had been bid up during the boom too high to be profitable once the consumers reassert their old consumption/investment preferences. The "depression" is then seen as the necessary and healthy phase by which the market economy sloughs off and liquidates the unsound, uneconomic investments of the boom, and reestablishes those proportions between consumption and investment that are truly desired by the consumers...
What does Mises say should be done, say by government, once the depression arrives? What is the governmental role in the cure of depression? In the first place, government must cease inflating as soon as possible. It is true that this will, inevitably, bring the inflationary boom abruptly to an end, and commence the inevitable recession or depression. But the longer the government waits for this, the worse the necessary readjustments will have to be. The sooner the depression-readjustment is gotten over with, the better. This means, also, that the government must never try to prop up unsound business situations; it must never bail out or lend money to business firms in trouble. Doing this will simply prolong the agony and convert a sharp and quick depression phase into a lingering and chronic disease. The government must never try to prop up wage rates or prices of producers' goods; doing so will prolong and delay indefinitely the completion of the depression-adjustment process; it will cause indefinite and prolonged depression and mass unemployment in the vital capital goods industries. The government must not try to inflate again, in order to get out of the depression. For even if this reinflation succeeds, it will only sow greater trouble later on. The government must do nothing to encourage consumption, and it must not increase its own expenditures, for this will further increase the social consumption/investment ratio. In fact, cutting the government budget will improve the ratio. What the economy needs is not more consumption spending but more saving, in order to validate some of the excessive investments of the boom. Thus, what the government should do, according to the Misesian analysis of the depression, is absolutely nothing. It should, from the point of view of economic health and ending the depression as quickly as possible, maintain a strict hands off, "laissez-faire" policy. Anything it does will delay and obstruct the adjustment process of the market; the less it does, the more rapidly will the market adjustment process do its work, and sound economic recovery ensue.
The Misesian prescription is thus the exact opposite of the Keynesian: It is for the government to keep absolute hands off the economy and to confine itself to stopping its own inflation and to cutting its own budget.
