XXX. INTERFERENCE WITH THE STRUCTURE OF PRICES
2. The Market's Reaction to Government Interference
The characteristic feature of the market price is that it tends to equalize supply and demand. The size of the demand coincides with the size of supply not only in the imaginary construction of the evenly rotating economy. The notion of the plain state of rest as developed by the elementary theory of prices is a faithful description of what come to pass in the market at every instant. Any deviation of a market price from the height at which supply and demand are equal is--in the unhampered market--self-liquidating.
But if the government fixes prices at a height different from what the market would have fixed if left alone, this equilibrium of demand and supply is disturbed. Then there are--with maximum prices--potential [p. 763] buyers who cannot buy although they are ready to pay the price fixed by the authority, or even a higher price. Then there are--with minimum prices--potential sellers who cannot sell although they are ready to sell at the price fixed by the authority, or even at a lower price. The price can no longer segregate those potential buyers and sellers who can buy or sell from those who cannot. A different principle for the allocation of the goods and services concerned and for the selection of those who are to receive portions of the supply available necessarily comes into operation. It may be that only those are in a position to buy who come first, or only those to whom particular circumstances (such as personal connections) assign a privileged position, or only those ruthless fellows who chase away their rivals by resorting to intimidation or violence. If the authority does not want chance or violence to determine the allocation of the supply available and conditions to become chaotic, it must itself regulate the amount which each individual is permitted to buy. It must resort to rationing.
But rationing does not affect the core of the issue. The allocation of portions of the supply already produced and available to the various individuals eager to obtain a quantity of the goods concerned is only a secondary function of the market. Its primary function is the direction of production. It directs the employment of the factors of production into those channels in which they satisfy the most urgent needs of the consumers. If the government's price ceiling refers only to one consumers' good or to a limited amount of consumers' goods while the prices of the complementary factors of production are left free, production of the consumers' goods concerned will drop. The marginal producers will discontinue producing them lest they suffer losses. The not absolutely specific factors of production will be employed to a greater extent for the production of other goods not subject to price ceilings. A greater part of the absolutely specific factors of production will remain unused than would have remained in the absence of price ceilings. There emerges a tendency to shift production activities from the production of the goods affected by the maximum prices into the production of other goods. This outcome is, however, manifestly contrary to the intentions of the government. In resorting to price ceilings the authority wanted to make the commodities concerned more easily accessible to the consumers. It considered precisely those commodities so vital that it singled them [p. 764] out for a special measure in order to make it possible even for poor people to be amply supplied with them. But the result of the government's interference is that production of these commodities drops or stops altogether. It is a complete failure.
It would be vain for the government to try to remove these undesired consequences by decreeing maximum prices likewise for the factors of production needed for the production of the consumers' goods the prices of which it has fixed. Such a measure would be successful only if all factors of production required were absolutely specific. As this can never be the case, the government must add to its first measure, fixing the price of only one consumers' good below the potential market price, more and more price ceilings, not only for all other consumers' goods and for all material factors of production, but no less for labor. It must compel every entrepreneur, capitalist, and employee to continue producing at the prices, wage rates, and interest rates which the government has fixed, to produce those quantities which the government orders them to produce, and to sell the products to those people--producers or consumers--whom the government determines. If one branch of production were to be exempt from this regimentation, capital and labor would flow into it; production would be restricted precisely in those other--regimented --branches which the government considered so important that it interfered with the conduct of their affairs.
Economics does not say that isolated government interference with the prices of only one commodity or a few commodities is unfair, bad, or unfeasible. It says that such interference produces results contrary to its purpose, that it makes conditions worse, not better, from the point of view of the government and those backing its interference. Before the government interfered, the goods concerned were, in the eyes of the government, too dear. As a result of the maximum price their supply dwindles or disappears altogether. The government interfered because it considered these commodities especially vital, necessary, indispensable. But its action curtailed the supply available. It is therefore, from the point of view of the government, absurd and nonsensical.
If the government is unwilling to acquiesce in this undesired and undesirable outcome and goes further and further , if it fixes the prices of all goods and services of all orders and obliges all people to continue producing and working at these prices and wage rates, it eliminates the market altogether. Then the planned economy, socialism of the German Zwangswirtschaft pattern, is substituted for the market economy. The consumers no longer direct production by their buying and abstention from buying; the government alone directs it. [p. 765]
There are only two exceptions to the rule that maximum prices restrict supply and thus bring about a state of affairs which is contrary to the aims sought by their imposition. One refers to absolute rent, the other to monopoly prices.
The maximum price results in a restriction of supply because the marginal producers suffer losses and must discontinue production. The nonspecific factors of production are employed for the production of other products not subject to price ceilings. The utilization of the absolutely specific factors of production shrinks. Under unhampered market conditions they would have been utilized up to the limit determined by the absence of an opportunity to use the nonspecific among the complementary factors for the satisfaction of more urgent wants. Now only a smaller part of the available supply of these absolutely specific factors can be utilized; concomitantly that part of the supply that remains unused increases. But if the supply of these absolutely specific factors is so scanty that under the prices of the unhampered market their total supply was utilized, a margin is given within which the government's interference does not curtail the supply of the product. The maximum price does not restrict production as long as it has not entirely absorbed the absolute rent of the marginal supplier of the absolutely specific factor. But at any rate it results in a discrepancy between the demand for and the supply of the product.
Thus the amount by which the urban rent of a piece of land exceeds the agricultural rent provides a margin in which rent control can operate without restriction the supply of rental space. If the maximum rents are graduated in such a way as never to take away from any proprietor so much that he prefers to use the land for agriculture rather than for the construction of buildings, they do not affect the supply of apartments and business premises. However, they increase the demand for such apartments and premises and thus create the very shortage that the governments pretend to fight by their rent ceilings. Whether or not the authorities resort to rationing the space available is catallactically of minor importance. At any rate, their price ceilings do not abolish the catallactic phenomenon of the urban rent. They merely transfer the rent from the landlord's income into the tenant's income.
In practice, of course, governments resorting to rent restriction never adjust their ceilings to these considerations. They either rigidly freeze gross rents as they prevailed on the eve of their interference or allow only a limited addition to these gross rents. As the proportion between the two items included in the gross rent, urban rent proper and price paid for the utilization of the superstructure, varies according [p. 766] to the special circumstances of each dwelling, the effect of rent ceilings is also very different. In some cases the expropriation of the owner to the benefit of the lessee involves only a fraction of the difference between the urban rent and the agricultural rent; in other cases it far exceeds this difference. But however this may be, the rent restriction creates a housing shortage. It increases demand without increasing supply.
If maximum rents are decreed not only for already available rental space, but also for buildings still to be constructed, the construction of new buildings is no longer remunerative. It either stops altogether or slumps to a low level; the shortage is perpetuated. But even if rents in new buildings are left free, construction of new buildings drops. Prospective investors are deterred because they take into account the danger that the government will at a later date declare a new emergency and expropriate a part of their revenues in the same way as it did with the old buildings.
The second exception refers to monopoly prices. The difference between a monopoly price and the competitive price of the commodity in question provides a margin in which maximum prices could be enforced without defeating the ends sought by the government. If the competitive price is p and the lowest among the possible monopoly prices m, a ceiling price of c, c being higher than p and lower than m, would make it disadvantageous for the seller to raise the price above p. The maximum price could reestablish the competitive price and increase demand, production, and the supply offered for sale. A dim cognizance of this concatenation is at the bottom of some suggestions asking for government interference in order to preserve competition and to make it operate as beneficially as possible.
We may for the sake of argument pass over the fact that all such measures would appear as paradoxical with regard to all those instances of monopoly prices which are the outcome of government interference. If the government objects to monopoly prices for new inventions, it should stop granting patents. It would be absurd to grant patents and then to deprive them of any value by forcing the patentee to sell at the competitive price. If the government does not approve of cartels, it should rather abstain from all measures (such as import duties) which provide business with the opportunity to erect combines.
Things are different in those rare instances in which monopoly prices come into existence without assistance form the governments. Here governmental maximum prices could reestablish competitive conditions if it were possible to find out by academic computation at which height a nonexisting competitive market would have determined [p. 767] the price. That all endeavors to construct nonmarket prices are vain has been shown. The unsatisfactory results of all attempts to determine what the fair or correct price for the services of public utilities should be are well known to all experts.
Reference to these two exceptions explains why in some very rare cases maximum prices, when applied with very great caution within a narrow margin, do not restrict the supply of the commodity or the service concerned. It does not affect the correctness of the general rule that maximum prices bring about a state of affairs which, from the point of view of the government decreeing them, is more undesirable than conditions as they would have been in the absence of price control.
Observations on the Causes of the Decline of Ancient Civilization
Knowledge of the effects of government interference with market prices makes us comprehend the economic causes of a momentous historical event, the decline of ancient civilization.
It may be left undecided whether or not it is correct to call the economic organization of the Roman Empire capitalism. At any rate it is certain that the Roman Empire in the second century, the age of the Antonines, the "good" emperors, had reached a high stage of the social division of labor and of interregional commerce. Several metropolitan centers, a considerable number of middle-sized towns, and many small towns were the seats of a refined civilization. The inhabitants of these urban agglomerations were supplied with food and raw materials not only from the neighboring rural districts, but also from distant provinces. A part of these provisions flowed into the cities as revenue of their wealthy residents who owned landed property. But a considerable part was bought in exchange for the rural population's purchases of the products of the city-dwellers' processing activities. There was an extensive trade between the various regions of the vast empire. Not only in the processing industries, but also in agriculture there was a tendency toward further specialization. The various parts of the empire were no longer economically self-sufficient. They were interdependent.
What brought about the decline of the empire and the decay of its civilization was the disintegration of this economic interconnectedness, not the barbarian invasions. The alien aggressors merely took advantage of an opportunity which the internal weakness of the empire offered to them. From a military point of view the tribes which invaded the empire in the fourth and fifth centuries were not more formidable than the armies which the legions had easily defeated [p. 768] in earlier times. But the empire had changed. Its economic and social structure was already medieval.
The freedom that Rome granted to commerce and trade had always been restricted. With regard to the marketing of cereals and other vital necessities it was even more restricted than with regard to other commodities. It was deemed unfair and immoral to ask for grain, oil, and wine, the staples of these ages, more than the customary prices, and the municipal authorities were quick to check what they considered profiteering. Thus the evolution of an efficient wholesale trade in these commodities was prevented. The policy of the annona, which was tantamount to a nationalization or municipalization of the grain trade, aimed at filling the gaps. But its effects were rather unsatisfactory. Grain was scarce in the urban agglomerations, and the agriculturists complained about the unremunerativeness of grain growing. The interference of the authorities upset the adjustment of supply to the rising demand.
The showdown came when in the political troubles of the third and fourth centuries the emperors resorted to currency debasement. With the system of maximum prices the practice of debasement completely paralyzed both the production and the marketing of the vital foodstuffs and disintegrated society's economic organization. The more eagerness the authorities displayed in enforcing the maximum prices, the more desperate became the conditions of the urban masses dependent on the purchase of food. Commerce in grain and other necessities vanished altogether. To avoid starving, people deserted the cities, settled on the countryside, and tried to grow grain, oil, wine, and other necessities for themselves. On the other hand, the owners of the big estates restricted their excess production of cereals and began to produce in their farmhouses--the villae--the products of handicraft which they needed. For their big-scale farming, which was already seriously jeopardized because of the inefficiency of slave labor, lost its rationality completely when the opportunity to sell at remunerative prices disappeared. As the owner of the estate could no longer sell in the cities, he could no longer patronize the urban artisans either. He was forced to look for a substitute to meet his needs by employing handicraftsmen on his own account in his villa. He discontinued big-scale farming and became a landlord receiving rents from tenants or sharecroppers. These coloni were either freed slaves or urban proletarians who settled in the villages and turned to tilling the soil. A tendency toward the establishment of autarky of each landlord's estate emerged. The economic function of the cities, of commerce, trade, and urban handicrafts, shrank. Italy and the provinces of the empire returned to a less advanced state of the social [p. 769] division of labor. The highly developed economic structure of ancient civilization retrograded to what is now known as the manorial organization of the Middle Ages.
The emperors were alarmed with that outcome which undermined the financial and military power of their government. But their counteraction was futile as it did not affect the root of the evil. The compulsion and coercion to which they resorted could not reverse the trend toward social disintegration which, on the contrary, was caused precisely by too much compulsion and coercion. No Roman was aware of the fact that the process was induced by the government's interference with prices and by currency debasement. It was vain for the emperors to promulgate laws against the city-dweller who "relicta civitate rus habitare maluerit."  The system of the leiturgia, the public services to be rendered by the wealthy citizens, only accelerated the retrogression of the division of labor. The laws concerning the special obligations of the shipowners, the navicularii, were no more successful in checking the decline of navigation than the laws concerning grain dealing in checking the shrinkage in the cities' supply of agricultural products.
The marvelous civilization of antiquity perished because it did not adjust its moral code and its legal system to the requirements of the market economy. A social order is doomed if the actions which its normal functioning requires are rejected by the standards of morality, are declared illegal by the laws of the country, and are prosecuted as criminal by the courts and the police. The Roman Empire crumbled to dust because it lacked the spirit of liberalism and free enterprise. The policy of interventionism and its political corollary, the Fuhrer principle, decomposed the mighty empire as they will by necessity always disintegrate and destroy any social entity.----------------
 For the sake of simplicity we deal in the further disquisitions of this section only with maximum prices for commodities and in the next section only with minimum wage rates. However, our statements are, mutatis mutandis, equally valid for minimum prices for commodities and maximum wage rates.
