It is also important to note that the adverse effects of tariffs in 19th century America were more than offset by the economic activity that constituted the western expansion across the continent. Some 20 million immigrants came to the United States in that century. Also, much economic growth came from transportation, farming, mining, and construction of infrastructure. In effect, the United States was a giant, continental‐​size free‐​trade zone, from the Atlantic to the Pacific — the equivalent of the distance from Madrid to Moscow.

Following the Civil War, some tariff liberalization occurred, mainly assuming the form of exempting items from duties, rather than reducing tariff rates. As Figure 1 illustrates, until that time, duties had covered a large percentage of imports, as shown by the close relationship between the tariff rate on all imports and that on dutiable imports only. But after the Civil War, those rates began to diverge sharply.

Turn‐​of‐​the‐​Century Tariffs

In the election of 1888, Republicans called for tariffs to protect American manufacturing. Benjamin Harrison’s defeat of Democrat free trader Grover Cleveland led to passage of the McKinley tariff in 1890. An interesting aspect of the 1890 debate over the tariff is that protectionists abandoned any pretense that high tariffs were needed to protect infant industries. Even mature industries, they argued, needed protection. They further argued that high tariffs were needed to reduce the Treasury’s surplus. They understood that sufficiently high rates would so discourage imports that tariff revenues would fall.8

Protectionist tariffs remained the bedrock of economic policy of the Republican Party for the next 20 years. Indeed, Republicans were so intent on passing the Payne‐​Aldrich tariff in 1909 that President William Howard Taft supported the 16th Amendment to the U.S. Constitution creating a federal income tax as the political price for Democratic support of the tariff.9 That has to have been one of the worst deals in history — a lose‐​lose situation if ever there was one.

The Underwood tariff of 1913, passed early in the administration of President Woodrow Wilson, liberalized trade somewhat. But as soon as the Republicans reassumed power after World War I, they raised tariffs again. The Fordney‐​McCumber tariff of 1922 generally increased tariff rates across the board. However, it also gave the President power to raise or lower existing tariffs by 50 percent.

Deepening Depression

The infamous Smoot‐​Hawley tariff of 1930 was the last outrage inflicted by the Republican protectionists. Rates on dutiable imports rose to their highest levels in over 100 years. Increases of 50 percent were common and some rates went up 100 percent. Table 1 indicates how much tariffs in creased during the 1920s as a result of both the Fordney‐​McCumber and Smoot‐​Hawley tariffs. A recent analysis estimates that the Smoot‐​Hawley tariff, on average, doubled the tariffs over those in the Underwood Act.10

Economists and historians continue to debate how important the Smoot‐​Hawley tariff was in causing the Great Depression.11 Whatever the degree, the effect certainly was adverse and the tariff was certainly bad policy. As Figure 2 indicates, world trade virtually collapsed following passage of the Smoot‐​Hawley tariff. Thus, if that tariff was not the single cause of the Great Depression, it certainly made a bad situation worse.

The Free‐​Trade Path

Politically, at least, in the long term the memory of the Smoot‐​Hawley tariff has kept Americans committed to a free‐​trade policy. For more than 60 years, a guiding principle of U.S. international economic policy has been that tariffs and other trade barriers should be reduced, that trade wars must be avoided at all costs, and that the best way to achieve those goals is through multilateral negotiations. Thus, the United States took the lead in establishing the General Agreement on Tariffs and Trade that reduced global tariffs in the decades following World War II, and spearheaded major GATT rounds of multilateral trade liberalization, including the Kennedy Round, Tokyo Round, and Uruguay Round.

In recent years, the free‐​trade consensus has begun to weaken. One must look back to 1929 to find protectionist rhetoric as heated as that commonly heard today. Throughout most of the postwar era, protectionists were embarrassed to call themselves protectionists. Today, however, prominent politicians such as Republican presidential candidate Pat Buchanan and Senator Ernest Hollings (D-S.C.) wear the label proudly.12 Yet protectionist policies have not been the source of America’s economic strength. And American policy, fortunately, remains largely directed toward free trade.
