Clashing Over Commerce: A History of U.S. Trade Policy

Douglas A. Irwin

During the first 16 months of Donald Trump's tumultuous presidency, the subjects of trade, tariffs, and America's role in the global economy have featured prominently in the public square. Although it may not have been as obvious before 2017, the conduct and consequences of U.S. trade policy--and, perhaps more so, the misconceptions surrounding it--have long stirred the people's passions.

That's not news to Dartmouth economics professor Douglas A. Irwin, whose latest treatise on the history of U.S. trade policy documents in exquisite detail how "The Tariff' has sparked bitter political, economic, and constitutional debate and has been a persistent source of sectoral conflict from the founding of the republic to the present.

Clashing over Commerce: A History of U.S. Trade Policy was written, according to Irwin, to fill a glaring void. The last major history of U.S. trade policy to be published was the 8th edition of A Tariff History of the United States in 1931, by Frank Taussig, the famous Harvard trade economist who became the first chairman of the U.S. Tariff Commission (predecessor of the U.S. International Trade Commission) when it was created in 1916.

In the introduction, Irwin references Federalist 10, in which James Madison notes that in every society there exist competing economic interests with contrasting views about what government policy ought to be. Alluding to what we would call the process of trade policy formulation today, Madison observed:

Shall domestic manufactures be encouraged, and in what degree, by restrictions on foreign manufactures? are questions which would be differently decided by the landed and the manufacturing classes, and probably by neither with a sole regard...
