There’s a lot of confusion about the justifications for and the consequences of tariffs in the news these days. The essay by Reuven Avi-Yonah, Doron Norotzki, and Tamir Shana entitled From Relic to Relevance, The Resurgence of Tariffs, attempts to remedy the situation. Its bottom-line conclusion is that it is extremely difficult to imagine a tariff system sufficiently robust to raise revenue adequate to replace the income tax even if revenue were the only concern. Moreover, it is virtually impossible to implement such a tariff without the real possibility of wreaking havoc on both domestic and international economies. The authors of Relic to Relevance (hereinafter “Relic authors”) want us all to understand why reliance on tariffs, especially as a replacement for the income tax, could be so dangerous.
As the Relic authors outline, introducing major changes in tax instruments is tricky business. In peace time, the United States Congress has rarely made such moves. The first time was the expected result of the adoption of the Constitution; expected because the need for a revenue source controlled by Congress and for uniform trade policy had been primary motivations for adopting a constitution to replace the Articles of Confederation. In its first substantive piece of legislation, Congress enacted the Act for Laying a Duty on Goods. This Act became law on the first Fourth of July celebrated under the new Constitution in 1789 (1 Stat. 24).
Even in those early days, the tensions outlined by the Relic authors between tariffs for protection and tariffs for revenue were present. James Madison had hoped to avoid the distortion of foreign relations that might occur as a result of ill-considered tariffs and tonnage duties. He further was aware of the domestic strife that could result from duties aimed at protecting domestic manufactures, especially when the cries for protection were regionally based. (These statements are contained, among other places, in Madison’s address to the House on Tonnage Duties). Congress nevertheless caved into the pressure to use its revenue-raising powers to provide an advantage to American shipping and to protect to nascent domestic industries.
But in 1789 the only realistic choices available to Congress for raising substantial amounts of revenue were either (1) a tariff imposed at a single rate on the value of all goods imported (generally referred to as an impost) or (2) a tariff that distinguished among types and sources of goods. (Tonnage duties on the ships used in trade, rather than on the goods being traded, might effectuate mercantilist trade policy but were never likely to raise much revenue. Property taxes, along with tariffs, had newly been permitted to Congress, but they require far more administrative capacity than the new Congress could muster, and they represented a far greater political risk.) The single-rate approach to taxing imports would clearly be the politically cleanest revenue-raising device. The latter—a tariff on specific goods—would, then as now, involve more political tension. As the Relic authors outline throughout the essay, the latter also involves a greater need for sophisticated calibration to avoid disastrously adverse economic consequences.
As is clear from the history recounted in Relic to Relevance, the use of the tariff for both protection and revenue has historically presented enormous challenges to the political institutions in the United States. Only after the income tax was introduced and later expanded during the First World War could Congress leave behind the friction and controversy associated with tariffs. In outlining this history, the Relic authors provide a valuable survey of the historical and economic literature on the subject of tariffs, and on the tax instruments most often thought to resemble tariffs.
Relic usefully provides a comparison of the political and economic ramifications of various revenue instruments available to the modern Congress. Relic also offers the reader several starting points for assessing whether a well-calibrated tariff system could possibly generate as much revenue as the federal government requires. Although the essay is written as if to outline the conditions that must be met in order to make such a tariff acceptable, it seems clear the authors ultimately are skeptical that these conditions can be met.
