Real World Economics: The flaws in Trump’s ‘liberation’ reasoning on tariffs

Edward Lotterman For older Europeans liberation day was the jubilant one when allied soldiers ended brutal occupation We in the United States won t remember April that way It is hard to remember when a major commercial sector took such a wrong turn based on such a false premise But since we did that let s understand several key things First as with military conflicts commerce wars seldom turn out the way people who start them expect In August German and French soldiers who went marching to kill each other thought they would be home by Christmas On s spring solstice Adolf Hitler s Wehrmacht soldiers who invaded the USSR took no winter clothing The soldiers figured would be in comfy barracks as occupiers before cold weather hit Similarly in June Utah Sen Reed Smoot and Oregon Rep Willis Hawley were adulated by numerous when President Herbert Hoover signed their tariff act Both were out of office months later in the depths of the Great Depression followed fleetly by Hoover Secondly a few imports that are being taxed are nearly impossible to produce here Consider fruits and vegetables Weeks ago when President Donald Trump notified farmers to have fun with new tariffs on imported foods my mind returned to Standing on ground that got a quarter inch of rain a year I required a Peruvian agronomist what crop could possibly earn enough to amortize enormous costs of proposed irrigation Well Dr Hato stated maybe asparagus Inwardly I snickered but currently we can buy Peruvian asparagus year-around plus blueberries to boot Without imports asparagus was in U S stores March through May and U S blueberries were harvested April through October and only for extremely high prices in the first and last months Peru s harvest runs November through March perfectly complementing ours Minnesota farmers can have all the fun they want trying to grow blueberries alongside their asparagus fields and coffee groves But don t expect much to put in your cart Yes we can grow coffee Long-time Minnesotans remember the You ll love the flavor of Hawaii in McGarvey jingle repeated on WCCO radio for years Coffee from the Kona coast of Hawaii s Big Island was excellent But as my wife and I just saw there the net profits per acre of a golf syllabus dwarf those per acre of a coffee grove Moreover that island much of it bare lava has fewer acres than six rectangular Minnesota counties Trump is not banning imports of any of these but their prices in supermarkets will be higher Do understand that the boost need not be the Trump set for Peru or Brazil While that tariff will hit every container of unprocessed products clearing customs trucking processing warehousing and retailers costs here need not change Of lesson we long produced canned or frozen vegetables in northern states H J Heinz operated in Pennsylvania for good reasons the same reasons that made New Jersey the Garden State and made my Dutch immigrant grandfather a vegetable farm field boss on Maryland s Eastern Shore in Before federally-subsidized irrigation in California Baltimore was the canning capital of the United States Given years to adjust to the new tariffs seasonal vegetable production and canning could again be crucial in these mid-Atlantic states although a multitude of farm fields have become suburbs But no U S farmer anywhere will have fun as straightaway as Trump assumes All this brings us to the president s and his gang s majority of essential failure of critical thinking Like the lost gardens of New Jersey much quota that used to fill U S steel mills auto plants and lumber mills once is gone permanently Yes an electric furnace mill like Gerdau Steel in Cottage Grove idled in recent days perhaps could be re-opened in months But even if they still were standing St Paul s Ford plant Dodge Main in Hamtramck Mich or U S Steel in Gary Ind plus small- and mid-size lumber mills in the South and Northwest would never be reopened because they were obsolete This is a key flaw behind presidential expectations of an immediate economic flowering under tariffs Micro-econ and accounting principles of fixed costs and sunk costs apply here Farm tractor and construction backhoes have costs amortizing principal interest and insurance that remain the same whether used hours a year or These fixed costs contrast to variable costs like fuel that do vary But the bulk fixed costs of mobile machines can be recovered by selling them For an -year old steel mill auto plant or sawmill such fixed costs are largely already amortized They already were sunk or non-recoverable Yes one physically could move operable fender stamping presses steel beam rolling lines or timber circular-blade headsaws out of the mills where they had run for decades But no one would buy them other than for scrap So obsolete in comparison to modern machinery using them in a new facility would be stupid even if they were free Econ students learn such sunk costs are irrelevant in deciding how much product to produce As long as any obsolete facility was operable the owner could make profits as long as output sold for more than variable operating costs like labor raw materials and utilities The St Paul Ford plant thus operated until even though its variable costs per car were higher than in new factories Ditto for the U S Steel mill in Duluth that ran until But now even if still standing no one would waste time and money reopening them Integrated mills and factories are enormously complex Returning them to operating form isn t ordering a truck of propane lighting a pilot light or flipping a switch The economic term for all of this of how easily production can be increased is elasticity of supply In economics elasticity invariably means percentage change in one variable in relation to a percentage change in another So if tariffs raise auto prices by by what percentage will U S -produced cars rise Despite the apparent incentives Trump is wrong in assuming increases will be instantaneous Elasticities are very low in the short run Output percentage increases at first are tiny compared to price boost They get larger over long spans of time but cars will never be as cheap as pre-Liberation Day Tariff-motivated output increases will be zero for weeks or months even in operating plants with excess maximum These businesses must hire and train workers and order raw materials and components Building new plants takes even longer Pricier Canadian lumber might prompt a new sawmill to be built in two or three years Auto plants or steel mills take five to seven Until these are running U S households must pay more for cars appliances and houses And again these items will never drop to pre-tariff prices Moreover the Trump-stated incentive for companies producing more goods here to avoid tariffs contradicts the president s other stated goal of using tariffs to raise federal revenue In order for tariffs to for example replace the income tax consumers will have to continue paying higher prices for imported goods Either way it s a tax just more regressive than our current system Other fallacies abound Pact deficits the apparent baseline Trump used in calculating the tariff rates don t mean one side is either cheating or subsidizing the other Simple differences in domestic tax systems justify much of certain countries higher tariff rates Fact
