Economics Volume II: Modern Economic Problems

§ 1. #Military and political motives for interference with trade.# The considerations set forth in the last chapter raise a strong presumption in favor of the sovereign state permitting its citizens to trade freely across its boundaries, as the best way to further their own prosperity and, on the whole and in the long run, that of the nation. Indeed, this presumption and belief has been held by nearly all serious students of the question, with more or less of modifications and qualifications, ever since Adam Smith published his work on the "Wealth of Nations" in 1776.[1] But in conflict with this belief has been the all but unanimous policy of nations from early times, throughout the Middle Ages, and down to this day, of interposing some special hindrances (of varying degrees and kinds) to this kind of trade. Sometimes this has been done by prohibitions, but more often by taxes imposed upon either imports or exports. Sometimes the attempt is made to justify the policy of governmental interference with foreign trade by arguments which crumble before the slightest examination, and again it is admitted that free trade is true in theory, but it is declared to be false in practice. The latter view is not to be entertained for a moment. If free trade in theory (as an explanation) is complete and true, it will in practice (as a plan of action) be sound and workable. In truth, however, the practical policy of governmental interference with foreign trade has always in part rested on other than the simple economic grounds.

Interference with free trade with the foreigner has always been in large measure due to political motives. In every petty medieval state or self-governing city, the aim was to make the economic boundaries coincide as nearly as possible with the political boundaries. Except for the trade in a few articles of comparative luxury this aim was at that time nearly attainable. The peasantry surrounding a fortified town and enjoying its protection were compelled to trade there. Down to our own time it has seemed to statesmen expedient to forbid or discourage trade that might nourish the economic power of future enemies. Sometimes governments have used embargoes, bounties, or tariffs as weapons to injure the trade of other nations and to secure diplomatic or commercial concessions. Often they have sought by tariffs to encourage the building of ships and the manufacture of armaments and of all kinds of munitions by private enterprise within their own borders, even when the immediate cost of these products was greater than if they were purchased abroad. In such cases it is always a question whether an outright expenditure would not be better, whether the government could not build its own arsenals and shipyards more economically than it can foster private enterprise by means of a protective tariff. However, the political (or military) argument for protection recognizes that it is in itself a costly (not a profitable) policy, and that the cost is only justified on the grounds that military necessity warrants the outlay.

The military argument as applied to the preparation of ships and munitions has no application to a tariff on those articles which have no bearing upon military power. But the most recent application of science and the mechanical arts to the uses of war has given new significance to a larger policy of industrial preparedness for military purposes. The year 1914 doubtless ushered in for the world a new epoch of protective and discriminatory tariff legislation determined by political rather than by direct economic considerations.

§ 2. #Revenue and protective tariffs.# An important distinction in principle is to be made between a tariff for revenue and a tariff for protection. A revenue tariff is a schedule of duties on goods entering or leaving a country, so arranged that the collection of taxes causes the least possible disturbance to domestic industry. Speaking generally, the duties may be on either imports or exports; but, as export duties are unconstitutional in the United States, our tariff discussions are concerned only with import duties. The most completely revenue-yielding tariff is one touching only articles which, even at the higher prices are not in the least to be produced profitably in the home country. A protective tariff is a schedule of import duties so arranged as to give appreciably higher prices to some domestic enterprises than they could obtain with free trade. It shuts out some foreign goods which would otherwise enter, an in so far it "protects" the domestic producer from the foreign competitors who would sell at lower prices than those at which he can or will sell. In other words, "protection" means governmental interference with the freedom of trade.

The distinction between revenue and protective tariffs, thus clear in principle, is not always easy to make in practice. It does not lie in the intention of the taxing power, but in the actual effects produced. Most tariffs combine the characteristics both of revenue and of protective measures. A tariff that reduces imports but does not cut them off entirely may be called either a revenue tariff with incidental protection or a protective tariff with incidental revenue. The difference is one of degree. But notice particularly that the two features of protection and of revenue are mutually exclusive. To the extent that one is present the other is impossible. A tariff rate that in whole or in part excludes the foreign article to that extent affords "protection" but does not yield revenue. Whenever the government collects a cent of tariff taxes, the domestic producer in so far and as respects that unit of goods is unprotected. Likewise, whenever any domestic producer enjoys "protection" in respect to any unit of goods, importation is in so far prohibited and the government is deprived of any revenue whatever derived from the production and sale of that unit of goods.

§ 3. #Growth of a protective system.# The protective policy developed at first accidentally, as it were, out of the practice of levying taxes for revenue only. Tolls, dues (or duties), customs (that is, in former times the customary dues paid by merchants, now the dues fixed by law), tariffs (that is, schedules or lists of rates of duties) were at first intended to raise revenues for the sovereign, the city, or the state. The unintended, and to some degree inevitable, result of the taxation of goods in commerce, whether imports or exports, is to prevent and discourage trade and to raise the prices of the goods imported. Any change in tariff duties, therefore, at once alters the previously existing adjustment of profits and of industries in a country.

The first effect of the tariff is the same as that of any new factor in enterpriser's cost; the same, for example, as that of a new domestic tax on an article or as that of a rise of freight rates—the domestic price of the taxed article tends to rise. Other results then follow. If the article cannot, even at the higher price, be produced within the country (as in the cases of oranges, spices, and coffee in England, Norway, and Sweden), its consumption is reduced. The lessening of demand may, however, depress somewhat the price in the producing country. But as such a tariff does not increase home production of the taxed article, it is therefore for revenue, not for protection.

But if the article can be profitably produced in the importing country at the new price, "home industries" will start. Where the transportation charges are low, as on the coasts and on the main lines of railways, some imported goods may be bought, while farther inland where transportation charges are higher home production of some or all grades of such goods may take place. If the whole demand at home is supplied and all imports stop, therewith cease all revenues to the government from that source. A completely protective tariff is completely prohibitive.

Experience abundantly shows that, with a few exceptions, due to climate and natural resources, it is impossible to put into effect the most moderate schedule of duties without the increase in price at once causing some men to shift their occupations, and to begin producing articles of the kinds that have risen in price. At once appears a group of "protected industries," the owners of which are dependent for the safety and profits of their investments, and the workmen in which are dependent for the security of their present jobs (possibly for the chance to continue the pursuit of highly skilled trades) on the continuance, if not the increase, of the existing tariff rates. A tariff may be adopted mainly from stress of financial need (as in our own history in 1789 or in 1861), but its modification or repeal cannot be decided by fiscal considerations. The "incidental protection" it affords has created a wealthy and influential group of employers and a large body of employees who are irresistibly tempted to exercise their influence in politics almost solely in favor of continuing and of increasing the rates to the sacrifice of the higher civic life of their communities. Of course the beneficiaries of the tariff usually believe sincerely that it is indispensable for the prosperity of the country as a whole, and they can do much to persuade others to the same opinion. This commercial motive for maintaining existing protective tariffs explains in large part their wide prevalence, whatever other reasons may be adduced in their justification.

§ 4. #The infant-industry argument.# Most free-trade writers concede a limited validity to the claim that protection may be used to encourage infant industries and thus diversify the industries of the country. If the natural resources of a land are adapted to an industry, it may be called into being earlier by a fostering protective tariff. This is merely anticipating and hastening the natural order of progress. In the American colonies the manufactures of such goods as iron, cloth, hats, ships, and furniture sprang up and continued not only without "protection," but despite numerous harassing trade restrictions made in the interest of English merchants. Can it be doubted that many of these industries would have developed and flourished after the adoption of the Constitution with no other favoring influences than those of rich resources and of economy in freights? In the Mississippi Valley since 1880 natural gas, abundant coal, ore, and timber have made possible a great growth of industries without protection against the Eastern states. Industries capable of eventual self-support must in most cases naturally appear in due time. Economic forces will bring them out. The protective system has often been likened to a hothouse, anticipating the season by a few weeks and at great cost. The question is whether the mere possession of the hothouse is a luxury worth the price, if meantime the products can be got more cheaply by trade. English manufactures flourished in the nineteenth century because they were well established, had excellent coal supplies, great stores of iron ore, and low-paid labor which did not have the opportunity of better alternatives, as did the American workman. If America had imported more (it would not have been all) of her iron and coal, the English mines would have begun to shown signs of exhaustion earlier, and America's advantage surely would have asserted itself in time. Her iron manufactures undoubtedly were hastened—they cannot truly be said to have been created—by the protective tariff.
