1.Introduction

Inthepasttwodecadesnumerousstudieshaveexaminedthecausalrelation-shipsbetweenenergyconsumptionandeconomicgrowth,witheitherincomeoremploymentusedasaproxyforthelatter.Todate,theempiricalfindingshavebeenmixedorconflicting.TheseminalarticleonthistopicwaspublishedinthelateseventiesbyKraftandKraft（1978）whofoundevidenceinfavorofcausalityrunningfromGNPtoenergyconsumptionintheUnitedStates,usingdatafortheperiod1947-1974.Theirfindingswerelatersupportedbyotherresearchers.Forexample,AkarcaandLong（1979）.foundunidirectionalGrangercausalityrunningfromenergyconsumptiontoemploymentwithnofeedback,usingUSmonthlydatafortheperiod1973-1978.Theyestimatedthelong-runelasticityoftotalemploy-mentwithrespecttoenergyconsumptiontobe-0.1356.

However,thesefindingshavebeensubjectedtoempiricalchallenge.AkarcaandLong（1980）,ErolandYu（1987a）,YuandChoi（1985）,andYuandHwang（1984）foundnocausalrelationshipsbetweenincome（peroxidebyGNP）andenergyconsumption.Onthecausalrelationshipbetweenenergyconsumptionandemploy-ment,ErolandYu（1987b,1989）,YuandJin（1992）,andYuetal.（1988）foundevidenceinfavorofneutralityofenergyconsumptionwithrespecttoemploy-ment,referredtoasthe‘neutralityhypothesis’.

Oneofthereasonsforthedisparateandoftenconflictingempiricalfindingsontherelationshipbetweenenergyconsumptionandeconomicgrowthliesinthevarietyofapproachesandtestingproceduresemployedintheanalyses.Manyoftheearlieranalysesemployedsimplelog-linearmodelsestimatedbyordinaryleastsquares（OLS）withoutanyregardforthenatureofthetimeseriespropertiesofthevariablesinvolved.However,ashasrecentlybeenproven,mosteconomictimeseriesarenon-stationaryinlevelsform（seeGrangerandNewbold,1974）.Thus,failuretoaccountforsuchpropertiescouldresultinmisleadingrelationshipsamongthevariables.

Followingadvancesintimeseriesanalysisinthelastdecade,recenttestsoftheenergyconsumptioneconomicgrowthrelationshiphaveemployedbivariatecausalityproceduresbasedonGranger（1969）andSims’（Sims,1972）tests.How-ever,thesetestsmayfailtodetectadditionalchannelsofcausalityandcanalsoleadtoconflictingresults.Forexample,recently,GlasureandLee（1997）testedforcausalitybetweenenergyconsumptionandGDPforSouthKoreaandSingaporeusingthestandardGrangertest,aswellascointegrationanderror-correctionmodeling.Theyfoundbidirectionalcausalitybetweenincomeandenergyforbothcountries,usingcointegrationanderror-correctionmodeling.However,usingthestandardGrangercausalitytests,theyfoundnocausalrelationshipsbetweenGDPandenergyforSouthKoreaandunidirectionalGrangercausalityfromenergytoGDPforSingapore.

Thedirectionofcausationbetweenenergyconsumptionandeconomicgrowthhassignificantpolicyimplications.If,forexample,thereexistsunidirectionalGrangercausalityrunningfromincometoenergy,itmaybeimpliedthatenergyconservationpoliciesmaybeimplementedwithlittleadverseornoeffectsoneconomicgrowth.Inthecaseofnegativecausalityrunningfromemploymenttoenergy（AkarcaandLong,1979）,totalemploymentcouldriseifenergyconservationpolicyweretobeimplemented.Ontheotherhand,ifunidirectionalcausalityrunsfromenergyconsumptiontoincome,reducingenergyconsumptioncouldleadtoafallinincomeoremployment.Thefindingofnocausalityineitherdirection,theso-called‘neutralityhypothesis’（YuandJin,1992）,wouldimplythatenergyconservationpoliciesdonotaffecteconomicgrowth.
