limitedbybusinessorregulatorybarriers.Second,theuptakeoftheGPTbymultipledownstreamsectorsmaybetoolow,inthesensethatifthesesectorswerecoordinatingtheiractivity,theywouldseethatfasteruptakeofthetechnologywouldsupportitsmorerapidimprovementbytheupstreaminnovator.ThepracticalsignificanceofthissecondpointisthatGPTsdevelopfasterwhenthere’salarge,demandingapplicationsector(avoidingtheneedtocoordinatesmallerones),suchastheU.S.DefenseDepartment’searlypurchasesoftransistorsandmicroprocessors.Helpman(1998,p.4)characterizedtheundersupplyproblemsasfollows:
GPTs introduce two-types of externalities: one between the GPT and the application sectors; another across the application sectors. The former stems from the difficulties that a GPT inventor may have in appropriating the fruits of her invention. When institutional conditions prevent full appropriation, the GPT is effectively underpriced and therefore, undersupplied. The latter stems from the fact that, since the application sectors are not coordinated, each one conditions its expansion on the available general-purpose technology. But if they coordinated a joint expansion, they would raise the profitability of the GPT and encourage its improvement. A better GPT benefits them all.
Akey(policy)implicationisthatinventorsofGPTshavegreatdifficultyappropriatingthefruitsoftheirinvestment,andmanagementwillbechallengedinfindingworkablerevenuearchitectures.Ownersofenablingtechnologiesfacesimilarchallenges.Asaresult,underinvestmentinGPTsandenablingtechnologiesisanearcertainty.Publicpolicyneedstoredressthisinsomefashion.SeveralfactorsconspiretorestricttheabilityofownersofGPTsandenablingtechnologiestocapturevaluefromdownstreamimplementers.First,designingabusinessmodeland/orcontrollingthenecessarycomplementaryassetsandtechnologiestointernalizemoreofthespilloversistypicallybeyondthescopeofwhatasinglefirmcando.AcaseinpointisPilkingtonGlassanditsinventionoffloatglass,whichis,arguably,animportantenablingtechnology.Thefloatprocess,introducedin1959,hadreducedproductioncostversusthedominantplateglassprocessbymorethanathirdbythetimethefirstlicensewasgrantedin1962,andbyabout75%by1974(Teece,2000,AppendixTableB.2).Ithasalsofacilitateddownstreaminnovationssuchasflatpaneldisplays.DespitePilkington’sstrongintellectualpropertypositionandtheevidentandquitesubstantialvalueofitstechnology,Pilkingtonlicensedthefloatprocessonanexclusiveterritorialbasistoallcomersatamere6%ofrevenues.Thisreflectsthefactthattheinventionwassouniversalinitsattractiveness,andfamily-ownedPilkingtonsounpreparedandunabletoimplementthetechnologybyitselfonaworldwidebasis,thatwidespreadlicensingseemedthebestalternative.Asaresult,amodestroyaltyforPilkingtoneffectivelypassedmostofthebenefitstomanufacturersandconsumers;Pilkingtonwasabletogarneronlyatinyshareofthetotalreturntothetechnologyforitself.Second,thefuturevalueofaGPTorenablingtechnologymaynotbeclearattheoutset;andevenifitis,theremayberegulatoryconstraintsthatlimitvaluecapture.Thetransistor,developedbyAT&T’sBellLabs,wasprotectedbypatents,butAT&Tlicensedthetechnologywidelyandalmostroyaltyfree.AT&T’slogicappearedtobethat,asalarge-scalebuyeroftelecomequipment,itwouldbenefitfromthecompetitionamongitslicensees,astrategicperspectivethat,atminimum,missedcapturingvaluefromthetechnologybeyondthetelecomindustry(Levin,1982).AT&Twasalsohighlyregulated,whichraisedadditionalbarrierstocommercializationandvaluecapture.
