A Historical Look at Tariffs

Chief Economist Eugenio J. Alemán discusses current economic conditions.

Tariffs seem to have become a staple of Americans’ dictionaries lately as the new administration uses this policy instrument to achieve objectives that are not directly tied to the reasons tariffs have been used in the past. That is, typically, the US has used tariffs to protect a sector of the economy either temporarily or, sometimes, for the long haul, and as an instrument for collecting fiscal revenues.

In fact, fiscal revenues from import tariffs were the largest source of fiscal revenues during the first 100 plus years of our country, as the graph below shows.

The US has used tariffs forever while the move to freer trade started after the Second World War and intensified during the last several decades. And while there are some that suggest otherwise, the US has benefited the most from this move toward freer trade. It is true that there are inequities, and some countries subsidize sectors and protect others in order to give those sectors a competitive advantage that would have normally been absent. But every country in the world, at some point in time, has done something similar.

At the beginning of our history as a nation-state, the South was so distrustful of the North that we enshrined the Export Clause into our Constitution. In Article 1, Section 9, Clause 5 of the constitution it says, “No Tax or Duty shall be laid on Articles exported from any State.” However, nothing was said about import taxes (i.e., tariffs), perhaps because in the early days the US government’s income came, fundamentally, from tariffs on imports. But tariffs were always a problem for the US economy. According to the CATO Institute, “From 1789 to 1934, tariff-seeking industries were notorious for diverting resources into rent-seeking, or the lobbying of Congress for preferential rates with bribes and backroom deals.”¹ The corruption generated by import tariffs, according to CATO, was one of the reasons the US passed the 16th Amendment of the Constitution, which created the federal income tax system.
