INTRODUCTION

InAugust2022,PresidentJoeBidensignedtheInflationReductionAct(IRA)intolaw.Thelate-breakingdealbetweenSenateMajorityLeaderChuckSchumerandSenatorJoeManchinofWestVirginia—theproductofadeadlockedSenaterequiringthateveryDemocraticsenatorbeonboard—surprisedevenWashingtoninsiders.

LesspleasantlysurprisedwastheEuropeanUnion(EU).ItcelebratedthefactthattheUnitedStatesfinallyhadanaggressiveclimatepolicy,applaudingtheadministration’scommitmenttoreduceemissionsfrom2005levelsby50–52percentby2030.1ButitfoundfaultwithanumberoftheIRA’sdetails.

Oneofitsmostimportantcomplaintswasthelaw’sdiscriminatory“BuyAmerican”(localcontent)incentives.Thelegislation’snewtaxcreditforelectricvehicles(EVs),forexample,initiallyseemedtodeemeligibleonlycarsassembledinNorthAmerica.Ifso,thisrulewouldshutoutaVolkswagenimportedfromGermanybutnotonemanufacturedinTennessee.Overthenextfewmonths,theTreasuryDepartmentwroteimplementingregulationsthattweakedkey

Thispapershowcasesthepolitical-economiccomplexityofUSandEUattemptstocooperateovercleanenergytransitionpolicytoaddressaglobalexternality.EVsarebutoneexampleofthechallengefacingpartnerswithintegratedsupplychains;similarlevelsofeconomicdevelopment;andsharedworriesoverclimateandotherenvironmentalproblems,risinginequality,workers,socialissues,anddemocracyitself.TheEVconflictlaidbarethedifferentwaysinwhichtheUnitedStatesandtheEuropeanUnionprioritizedeconomicefficiency,WorldTradeOrganization(WTO)rules,theapproachtononmarketeconomies,andnationalsecurityvulnerabilitiesthatarisefromdependingonanauthoritarianregimesuchasChinaforimportsourcingofcriticalinputs.

ThedetailsmatterforhowtheIRAanditsimplementingregulationsaffectincentivesforinternationaltradeinEVsandtheirkeyinputs.Thepaperexploresthosedetails,includingthepotentiallytransformativedecisionthatleasedvehiclescouldqualifyforconsumertaxcreditsunderaseparateandindependenttrackoftheIRAthatdidnothavethosediscriminatorylocalcontentincentives.Italsoexaminesnumerousotherpolicies—includingtheconsiderabledifferencesinUSandEUimporttariffsonEVstowardeachotherandtowardthirdcountries,suchasChina—thatarealsolikelytoaffectEVtradepatternsinwaysthatoffsetsomeeffectsoftheIRA.Inthepre-IRApolicylandscape,forexample,EUimportsofEVswereincreasinglydominatedbysourcingfromChina,whichhadlargelydisplacedUSexports.Furthermore,theUnitedStatescontinuedtoimportlargenumbersofEVsfromEuropeevenafterimplementingtheIRA.Whetherthistrendcontinues,ofcourse,remainsanopenquestion.

1ModelestimatesfromBistline,Mehrotra,andWolfram(2023)suggestthattheIRAcouldhelptheUnitedStatesreduceemissionsfrom2005levelsby32–42percentby2030,a6–11percentagepointimprovementrelativetothebusinessasusual(non–IRA)projections.
