Tariffs and Trade Restrictions

by Steve G. Parsons, Ph.D.

The Power of Trade.  One of the most fundamental, and powerful, concepts in economics is that of comparative advantage.  One key lesson from this concept is that the business or country that is able to produce a good at the lowest cost is the business or country that should, in fact, produce that good.  The other key lesson is that you can’t be best (or even good) at everything.  Recognizing this is at the heart of the business concept of “core competency”; you should find out what you do best and focus on that. See the fiscally conservative Cato Institute’s multipart series on trade (Comparative Advantage | Cato Institute).

With free trade both parties to the trade are better off.  Trade is what allows goods to be produced at their lowest cost and then consumed across the populations for which trade exists; trade is an amazing engine for economic growth.  It was a major factor in the growth of virtually every civilization, and it continues to be a key factor for economic growth around the world. As the US Chamber of Commerce notes: “We can heed the lessons of history which suggest that no nation has ever remained prosperous by walling itself off.” (The U.S. Chamber's Plan to Help Americans Compete and Win in the Worldwide Economy | U.S. Chamber of Commerce)

Trade Restrictions.  For any business, it is best (selfishly) to convince government to constrain your competitors (but not yourself); this includes international competitors.  Such international trade restrictions can take different forms but three are most common.  First, full prohibition on the importation of specific goods.  Second, a quota limiting the volume of importation allowed.  These first two are sometimes called nontariff barriers.  And third, and most commonly used, a tax on imports (called a tariff).

President Trump claimed that U.S. tariffs on Chinese goods (for example) were paid by the Chinese.  This is a bit like claiming the cost of the U.S. border wall will be paid by Mexico.  U.S. import tariffs are paid by Americans who import foreign goods. In the vast majority of cases, these are American companies paying the tariff, using the those inputs to make American products here in the US and then largely passing these taxes along to the American consumers of their goods.

In explaining how imports help American businesses the U.S. Chamber of Commerce notes that: “Companies’ imports of intermediate goods, raw materials, and capital goods account for more than 60% of all U.S. goods imports – lowering the cost for manufacturers and other businesses and helping them hone their competitive advantage.” (Available at, The Benefits of International Trade | U.S. Chamber of Commerce (uschamber.com)).  Therefore, tariffs may help some American businesses (by protecting them from competition) but hurts others who import components to make their own American products.

Are Imports Bad?  Some people seem to believe that exports are good, but imports are bad.  This illustrates a fundamental misunderstanding of trade.  With ancient trade there was an exchange of one good for another; by definition, there was simultaneous “importing” and “exporting” of goods.  Modern trade requires both a buyer and a seller.  International trade, again by definition, requires both imports and exports to exist; both imports and exports make the relevant parties better off (otherwise they would not engage in trade), hence they are both “good”.

Consider what else the U.S. Chamber of Commerce has to say: “Imports help Americans too. They mean lower prices for American families as they try to stretch their budgets—and for companies seeking raw materials and other inputs. Access to imports boosts the purchasing power of the average American household by $18,000 annually” (Available at, The U.S. Chamber's Plan to Help Americans Compete and Win in the Worldwide Economy | U.S. Chamber of Commerce).

The Costs of Restrictions – Smoot-Hawley Tariff 1929/30 an Example

In May 1929, looking to curry favor with farmers, the U.S. House passed a bill to greatly increase international tariffs.  On October 27, in a test vote on the bill the free-trade group switched and voted for the expanded tariffs.  U.S. stock prices dropped in the last hour of trading and the following day, October 28, is christened Black Thursday – the start of the stock market crash. (Reynolds 1979) 

Prior to Herbert Hoover signing the Smoot-Hawley tariffs more than a thousand economists from 179 colleges and universities signed a statement that was codified in the Congressional Record, May 5, 1930, pp 8327-28.  The statement includes the following language: “We are convinced the increased protection duties will be a mistake”  … By raising prices … and compelling consumers to subsidize waste and inefficiency in the industry.  … Our export trade, in general would suffer.” (Irwin 2011).  Their predictions came true.  Many major countries retaliated with tariffs on U.S. goods while others simply boycotted U.S. goods.  Within three years U.S. exports fell to only 35% of their pre-tariff levels (U.S. total imports, exports and trade balance 1790-1970 | Statista).  A substantial portion of this decline was caused by Smoot-Hawley tariffs.  In 1988 the Economic Report of the President described the tariffs as “… probably the most damaging piece of legislation signed in the United States.” (p. 147).

The Costs of Restrictions – 2002 Bush Steel Tariffs – an Example

In 2002, George W. Bush implemented tariffs on certain steel imports.  This raised the cost of steel for American companies using steel to produce their products and was particularly costly for small companies. “Ninety-eight percent of the 193,000 U.S. firms in steel-consuming sectors, at the time of the Bush steel tariffs, employed less than 500 workers.” (Lessons from the 2002 Bush Steel Tariffs | Tax Foundation.) This also triggered imports of steel-containing products (since American companies had to use higher-priced steel).  As a consequence of the tariffs about 200,000 Americans lost their jobs in those steel-consuming sectors (from February to November 2022) – this is greater than the total number of employes in the U.S. steel manufacturing sector at the time. (The Unintended Consequences of U.S. Steel Import Tariffs: A Quantification of the Impact During 2002, available at Microsoft Word - 2002 jobstudy2 2023).

The Costs of Restrictions – Trump 2018 Tariffs - another Example

In 2018 President Trump implemented a series of tariffs and tariff increases on a variety of products including solar panels, washing machines, steel, and aluminum.  Eventually the tariffs were broadened to cover thousands of other products from China.  As with the Smoot-Hawley tariffs nearly 90 years earlier these U.S. tariffs triggered retaliatory tariffs by other countries. 

The Tax Foundation summarized the effects of these tariffs as follows: “The Trump administration imposed nearly $80 billion worth of new taxes on Americans by levying tariffs on thousands of products valued at approximately $380 billion in 2018 and 2019, amounting to one of the largest tax increases in decades.” “Trump Tariffs & Trade War: Details & Analysis of Economic Impact (taxfoundation.org).  Remember, tariffs are taxes and taxes cause higher prices for consumers.

The Costs of U.S. Tariffs.  There are two categories of costs that occur with such increases in tariffs.  First, American companies pay the tax on imports.  This increases their costs which they will tend to pass onto American consumers. (The White House Still Can’t Grasp That Americans Pay US Tariffs | Cato at Liberty Blog). This also means that there will be pressure on these American companies to scale back on production as American consumers respond to the higher prices.  At the margin, some employees will be laid off; this is particularly true for companies facing elastic (price responsive) demand for their services.  The Tax Foundation estimates that the U.S. tariff imposed by Trump led to a loss of 166,000 American jobs (Trump Tariffs & Trade War: Details & Analysis of Economic Impact (taxfoundation.org)).  

“New research by economists from the Federal Reserve Bank of New York and Columbia University found U.S. companies lost at least $1.7 trillion in the price of their stocks due to increased U.S. tariffs against imports from China.” Trump’s Trade War Cost U.S. Company Stock Prices $1.7 Trillion (forbes.com) June 1, 2020.

The Costs of Retaliatory Tariffs by Other Countries.  Second, when other countries retaliate with higher import tariffs of their own on American-produced goods the foreign companies importing our goods respond by cutting back themselves as the cost of using American goods rises.  American exporters sell less and face pressure to scale back production.  At the margin, some employees of American exporting companies will be laid off.  The Tax Foundation estimates that in response to U.S. 2018 tariffs retaliatory tariffs by other countries caused the loss of 29,000 jobs at American companies attempting to export their products. (Trump Tariffs & Trade War: Details & Analysis of Economic Impact (taxfoundation.org).  For example, agricultural imports to China dropped about $15 billion due to the tariffs (Impact of the Trade War on U.S. Agriculture — EMORY ECONOMICS REVIEW). This triggered a $28 billion proposed farm bailout by Trump. (Farmers Say Trump’s $28 Billion Bailout Isn't a Solution - Bloomberg)

“Based on 2022 import levels, these tariffs currently impact over $350 billion of imports and exports and increase consumer costs by roughly $51 billion annually.” (The Total Cost of U.S. Tariffs - AAF (americanactionforum.org)

The Loss of Personal Freedom. Every consumer has the right to preferentially purchase US goods, goods from their state, or their local community. US companies similarly have the right to purchase inputs as they choose to best fit their business needs. Tariffs strip away our personal freedom by forcing us to face prices that don’t reflect the underlying costs of producing goods. This can create hardships for the family or company barely scraping by. Accepting tariffs and protectionism means placing your faith in the federal government, and abandoning faith in US free enterprise and Americans.

Trump’s 2025 “Liberation Day” Tariffs and Aftermath. The April 2, 2025 Rose Garden presentation on tariffs was highly misleading. The values in the graphs did NOT reflect the tariffs other countries charge the US. Indeed, only 36 countries in the world have average tariffs above 10%; these countries are small and poor with a per-capita income of about $3,300. It is bizarre indeed to now put the US into this group.

Also, the US tariffs represented the largest US tax increase in over 40 years (Trump's Tariffs: Biggest Tax Hike Since 1982). Through December 4, 2025 they will cost $1,230 per household (TPC Tariff Tracker | Tax Policy Center). They created business and political uncertainty, which is costly. Farmers lost $38.5 billion just in three crops (US farmers face $44 billion in losses as costs rise and markets shrink - Investigate Midwest). Between April 2 and July 14 alone there were 28 tariff flip-flops (Trump Tariff Flip-Flops: ‘TACO Trump’ Has Changed His Mind 28 Times Since ‘Liberation Day’).

These policies have created trade isolationism for the US and have pulled most other foreign countries closer together. In particular, the US tariffs have strengthened ties between China and the rest of the world (New Tariffs Will Push Countries Closer to China | Cato at Liberty Blog, and U.S. allies looking to China for deals as Trump threatens them with tariffs : NPR).

Now that the Supreme Court has invalidated the 2025 tariffs, there appears to be some foot-dragging in providing refunds to US companies that paid the tariffs; this could cost taxpayers an additional $700 million a month.

Conclusion.  Tariffs are taxes on American businesses, and they are universally recognized as bad economic policy.  Indeed, why else would over 1000 economists from 178 universities agree to sign the same document – condemning the Smoot-Hawley tariffs.  Tariffs, or other trade restrictions, distort trade and comparative advantage – the low-cost producer of a good may no longer be producing that good and costs are increased. Tariffs (or other trade restrictions) increase costs for American businesses and increase prices for American goods and lead to the loss of American jobs. U.S. tariffs can trigger retaliatory tariffs by other countries or voluntary consumer boycotts leading to reduced exports and more losses of American jobs. They raise prices and reduce productivity and efficiency in America.

Consider the advice from the fiscally conservative Cato Institute: “International trade is generally driven by the ability of people in various countries— through comparative advantages—to deliver lower‐​priced goods to consumers. If policymakers want to lower consumers’ costs [to cut inflation and improve affordability], they can encourage more trade by eliminating tariffs and nontariff barriers.” (Defending Globalization: Economics | Cato Institute).
