Nevertheless, as globalisation gathers momentum, views also exist that tourism may in actual fact not signicantly stimulate long-term economic growth as many informal agents bring in illegal workers to Malaysia using tourism as a channel. It may be hard to differentiate between genuine tourists and those who actually arrive in search for jobs (Kassim, 1997). In 1995, only 600 thousand foreign workers in Malaysia were illegal. The number subsequently increased to 2.1 million as observed during the implementation of the Illegal Immigrant Comprehensive Settle- ment Programme (Augustin & Lee, 2012). In view of these coun- terfactual data, doubts have arisen regarding the appropriateness of emphasising on tourism as a key sector for driving long-term economic growth in order to attain the high income status by 2020. As not all tourist arrivals involve genuine tourists, higher rates of arrivals do not necessarily mean higher rates of tourism earnings. In fact, UNWTO (2012) noted that Malaysia's ranking in terms of tourism earnings was much lower than the ranking by tourist arrivals. In view of these reservations, there is an urgent need for a more accurate empirical assessment of the actual impact of tourism on Malaysia's economic growth.

IntroductionTraditionally, economic prosperity has been linked to growth inthe agricultural and manufacturing sectors as well as the inux offoreign capital. Whilst, the role of tourism in economic growth hasoftenbeendownplayedandregardedasanon-growthorientedsector, henceattractinglittleattentionof botheconomists andpolicymakers(Papatheodorou, 1999). Today, tourismhasbecomeone of the rapidly growing services sectors of the world. This hasprompted the Malaysian government to set tourism as a key sectorfor invigoratingMalaysia's long-termeconomic growth. Specif-ically, the 10th Malaysia Plan (2011e2015) has identied thetourism sector as one of the National Key Economic Areas (NKEAs)for transforming Malaysia into a high income nation by 2020.Nevertheless, asglobalisationgathersmomentum, viewsalsoexist that tourismmayinactual fact not signicantlystimulatelong-termeconomic growthas manyinformal agents bringinillegal workers to Malaysia using tourism as a channel. It may behardtodifferentiatebetweengenuine tourists andthosewhoactually arrive in search for jobs (Kassim, 1997). In 1995, only 600thousandforeignworkersinMalaysiawereillegal. Thenumbersubsequently increased to 2.1 million as observed during theimplementationof theIllegal Immigrant ComprehensiveSettle-ment Programme (Augustin& Lee, 2012).In view ofthese coun-terfactual data, doubts have arisen regarding the appropriateness ofemphasisingontourismas akeysector for drivinglong-termeconomicgrowthinorder toattainthehighincomestatusby2020.

Inviewofthesereservations, thereisanurgentneed for a more accurate empirical assessment of the actual impactof tourism on Malaysia's economic growth.From our reading of earlier studies on the relationship betweentourism and economic growth, we nd that this topic has attractedalot ofinterest amongst researchers,particularly afterthestudyofBalaguerandCantavella-Jord a(2002).

To conserve space, we wouldonly review some selected studies and those related to Malaysia.Forexample, NarayanandPrasad(2003), Dritsakis(2004), Brida,Carrera, and Risso (2008), Katircio glu (2009, 2011), Tang andAbosedra (2014a, 2014b), Hye andKhan(2013), Al-mulali, Fer-eidouni, Lee, andMohammed(2014), BouzahzahandEl Menyari(2013), and Jalil, Mahmood, and Idrees (2013) discovered thattourism affects economic growth. Therefore, they concluded that thetourism-led growth hypothesis is valid. However, Oh (2005), PayneandMervar (2010), andLee (2012) arguedthat it is economicgrowth that affects tourism rather than the other way round. Hence,these studies instead support the growth-led tourism hypothesis.As far as Malaysia is concerned, several studies have been con-ductedtoanalyse the role of tourismineconomic growthassummarised in Table 1. Generally, the table shows that the causalrelationshipbetweentourismandeconomicgrowthinMalaysiaremains a controversial subject. For example, Nanthakumar,Ibrahim, andHarun(2008), Kadir, Nayan, andAbdullah(2010)andTang(2011a)foundthattourismexpansionislesslikelytopromote economic growth. Whilst,Lau,Oh, and Hu (2009), LeanandTang(2010), OthmanandSalleh(2010), Kadir andKarim(2012), Othman, Salleh, andSarmidi (2012), Cheam, Mahmood,Abdullah, and Ong (2013), and Tang (2013) discovered thattourismexpansioncouldplayanimportant roleinstimulatingMalaysia's economic growth. All these studies however haveweaknesses that this study aims to address. They mainly involvedtheuseof bi-variatemodelsand/orad-hocmodel specicationswhich are not based upon any theoretical model.1Although esti-mation via ad-hoc model specication is relatively easy and simple,itishard tointerprettheresultsifthey arenotbaseduponanyeconomic theory. Apart fromthese, noneof thesestudies hasconsideredthepossibleimpactof structural breaksinunitroottesting.Accordingto Perron (1989),standardunit root tests mayhave lowpower whendata series containstructural break(s).Therefore, theresultsofthesepastMalaysianstudiesarehighlyquestionable and may be inaccurate.Motivated by the aforementioned shortcomings, the goal of thispaper is tore-investigatetheimpact of tourismexpansiononMalaysia'seconomicgrowthinamultivariateframework. Unlikethe earlier studies, we contribute to the literature by analysing theroleof tourisminMalaysia'seconomicgrowthbasedupontheneoclassical growthmodel. Variouseconometricapproachesareemployed in this study. First, apart from the standard augmentedDickey-Fuller (ADF) unit root test, we also employ the endogenousbreakunit root test developedbyZivotandAndrews(1992) todeterminetheorder of integrationof eachseries. Second, thesystem-wide cointegration technique proposed by Johansen (1988)and Johansen and Juselius (1990) is used to determine the presenceoflong-run equilibriumrelationshipsamongst economic growth,tourism and other determinants. Gonzalo (1994) revealed that thistechnique performs better than the other cointegration techniqueseven when the disturbance term is non-spherically distributed andthe lag structure is mis-specied. In addition, Tang (2011b) notedthat the Johansen-Juselius cointegration test is not sensitive to thechoice of the dependent variable because it treats all variables asendogenous. Lastly, thecausalrelationshipbetweentourismandeconomic growth in Malaysia will be ascertainedby the Grangercausality test.The rest of this paper is organised as follows. The next sectionwill explain the theoretical model and the data used in this study.Section3willdiscusstheeconometricproceduresfollowed. Theempiricalndings will then be presented in Section 4 followed byconcluding remarks in Section 5.2. Theoretical model and dataInthis study, we use the following Solow's (1956) growthframework derived from the CobbeDouglas production function tojustify the role of tourism in economic growth:ln

According to Mankiw, Romer,and Weil (1992), the growth rate of gd is approximately 5 per centand constant over time.Thisstudyutilisesannualtimeseriesdatafrom1975to2011extracted from variousdatabases. Annualdataon per capitarealGNP, per capitareal GNS, per capitareal tourismreceipts andpopulation growth rate are extracted fromthe InternationalFinancial Statistics(IFS), theWorldDevelopment Indicators(WDI)and the CEIC databases.However,the annual series on polity2 iscollected from Polity IV Project (Marshall, Gurr, & Jaggers, 2013).This dataset has been extensively used by earlier studies to measurepolitical stability (e.g. Aisen & Veiga, 2006, 2013; Zureiqat, 2005).The score of polity2ranges fromstronglyautocratic (10) tostrongly democratic (10). Therefore, high positive scores of polity2indicate politically stability. All variables are transformed intonatural logarithm to induce stationarity in the variance-covariancematrix and that therst differences of the variables can be inter-preted as growth terms.3. Econometric methods3.1. Zivot-Andrews unit root testIn order to examine the order of integration of the data series,weemployboththestandardADFunitroottestandtheZivot-Andrewsunitroottestwithonestructural break. Asthetestingprocedure for the ADF unit root test is well explained, the presentsectionmerelyfocusesontheZivot-Andrewsprocedure. Inthisstudy, we use two versions ofthe endogenousbreak model pro-posedbyZivot andAndrews(1992) todeterminetheorderofintegration. Model Aallows for a breakinthe intercept only,whereas Model C allows for a break in both the intercept and theslope of the trend function. The testing models can be written as:Model A : Dwt k0a1wt1b1t k1DUtXpj1cjDwtjx1t(3)Model C : Dwt k0a1wt1b1t k1DUt b2DTtXpj1cjDwtjx2t(4)whereDistherstdifferenceoperator, xitarewhitenoiseandnormally distributed disturbance terms. Dwtjare the laggeddependent variablesaddedintotheequationstoremoveserialcorrelationandtoensurethatthedisturbancestermsarewhitenoise. p is the optimal lag length determined by the Akaike's Infor-mation Criterion (AIC).DUt is the dummy variable for astructuralbreak in intercept occurring at time TB, whereas DTt is the dummyvariable for a trend shift, where DUt 1 and DTt tTB if t > TB and0otherwise. Thepotential breakpoint(TB)isselectedwheretheabsolute term of the ADF t-statistic for wt1 is maximised.3.2. System-wide JohanseneJuselius cointegration testTo perform the system-wide JohanseneJuselius cointegration test,we estimate the following vector error-correction model (VECM):DWt FD PWt1Xk1i1GiDWtiyt(5)whereWtisavectorof vevariables, namely, lnGNPt, lnTOURt,lnPSt,lnGNStand ln(ngd)t.

If the LR(ltrace) test statistic isgreater than the critical value, this indicates that the null hypoth-esis of no cointegration can be rejected. Therefore, one canconclude that the variables are cointegrated and a meaningful long-run relationship can be derived.3.3. Granger causality analysisIn this section, we discuss the testing procedure for the Grangercausality test. In the context of the present study, we may either usethe rst difference vector autoregression (VAR) model or the vectorerror-correctionmodel (VECM)toexaminethedirectionofcau-sality between Malaysia's economic growth and tourism. Accordingto Granger (1988), if a set of variables are cointegrated, one shoulduse the VECM because it takes into account the short-run and long-runelements. However, intheabsenceofcointegration, onecanonly detect the short-run causal relationship using therst differ-ence VAR model. Assuming that the variables are cointegrated, thedirection of causality between economic growth and tourism canbe tested by estimating the following equations.DlnGNPt a0u1DUM98 Xkj1hjDlnGNPtjXkj04jDlnTOURtjXkj0gjDlnPStjXkj0fjDlnGNStjXkj0wjDlnn g dtjp1t1m1t(6)DlnTOURt a1u1DUM98 Xkj14jDlnTOURtjXkj0hjDlnGNPtjXkj0gjDlnPStjXkj0fjDlnGNStjXkj0wjDlnn g dtjp2t1m2t(7)whereD is therst difference operator, and t1 is the one periodlagged error-correction term derived from the long-run equation.mit's are the disturbance terms assumed to be normally distributedandwhitenoise.

Similarly, totestthateconomicgrowthdoesnot Granger-causetourism, weestimateequation (7) and test the null hypothesis H0:hj0 using the LR test.For the long-run causality, one can test the signicance of the oneC.F. Tang, E.C. Tan / Tourism Management 46 (2015) 158e163 160period lagged error-correction term. From equation (6),p1s0 im-plies that there is causality fromtourism to economic growth in thelong-run, whereas p2 0inequation(7)meansthateconomicgrowth does not Granger-cause tourism in the long-run.4. Empirical resultsPrior to testing for the presence of cointegration, it is necessary todeterminetheorderof integrationof eachseries. Inthepresentstudy, we performthe ADF unit root test as well as the Zivot-Andrewsunit root test with structural breaks to check the orders of integrationof the data series. Table 2 reports the results of both unit root tests. Atthe 5 per cent signicance level, the results of the ADF test indicatethat all the variables are non-stationary at levels, but they are sta-tionary afterrst differenced. Likewise, the Zivot-Andrews unit roottestnds no additional evidence against the results of the ADF unitroottest. Therefore, bothunitroottestsconsistentlysuggestthatlnGNPt, lnTOURt, lnPSt, lnGNStand ln(ngd)tare integrated of orderone orI(1). This is in line with thendings of Nelson andPlosser(1982) that most of the macroeconomic series are I(1).Since both unit root tests consistently suggest that all variablesareI(1), wecanproceedtotest for thepresenceof along-runequilibrium relationship between Malaysia's economic growth andits determinants using the system-wide JohanseneJuselius cointe-grationapproach. Inordertoperformthiscointegrationtest, weshouldcorrectlydeterminethelaglengthandthedeterministiccomponents(i.e. constant andtrend) intheVARmodel. Thisisbecause the statistical inferences of the JohanseneJuselius cointe-gration test are very sensitive to these two issues (e.g. Hall, 1991;Johansen, 1995). Toaddresstheseissues, weemploythesystem-wide Akaike's Information Criterion (AIC) to select an optimal laglengthandthePantulaprincipletodeterminethedeterministiccomponentsintheVARmodel. Thecalculatedsystem-wideAICstatistics suggest using a VAR model with 3 lags, while the Pantulaprinciple indicates that Model 3 (i.e. intercept in the cointegratingequationandalineartrendinthedata)isthemostappropriatemodel for our dataset. Apart from these, it is also important to pointout here that the standard JohanseneJuselius statistics for cointe-gration are biased toward rejecting the null hypothesis of no coin-tegration (Cheung &Lai, 1993). On the basis of Monte Carlosimulation, Podivinsky (1998) added that the size distortion prob-lemwith the JohanseneJuselius cointegration test is obvious,especially when the sample size is less than 100 observations. Giventhe sample size of this study is small (i.e. T 37), we circumvent thesize distortionproblemby applying the formula suggestedbyReinselandAhn(1992)toadjustthestandardJohanseneJuseliusstatistics. Theresultsofthesystem-wideJohanseneJuseliuscoin-tegration test are presented in Panel A of Table 3. Importantly, wend that both the adjusted and the unadjusted LR(ltrace) statisticsconsistently reject the null hypothesis of no cointegration at the 1per cent signicance level. Therefore, we are able to conclude thatlnGNPt, lnTOURt, lnPSt, lnGNStandln(ngd)tarecointegrated.Thus, thereisameaningful long-runrelationshipbetweeneco-nomic growth and its determinants in Malaysia.Having found that the variables are cointegrated, we estimatethelong-runrelationshipbetweenMalaysia's economicgrowthand its determinants using the Ordinary Least Squares (OLS) esti-matorbecauseithassuperiorperformance insmallsamples.2Inaddition, Stock (1987) revealed that when the variables are found toTable 2The results of unit root tests.Variables ADF Zivot-Andrews unit root test with one breakTest statisticsModel A Model CBreakyearTeststatisticsBreakyearTeststatisticsLevel:lnGNPt3.060 (3) 1998 2.933 (1) 1998 2.749 (1)lnTOURt3.035 (1) 1990 4.112 (1) 1994 4.407 (1)lnPSt1.152 (0) 2005 2.001 (0) 2005 3.881 (0)lnGNSt3.068 (0) 1998 3.070 (0) 1998 3.362 (0)ln(n gd)t 1.866 (3) 1988 2.424 (3) 1994 4.037 (3)First difference: Critical valuesaDlnGNPt4.301 (0)***Model A: Model C:DlnTOURt6.123 (3)***1 per cent 5.340 1 per cent 5.570DlnPSt5.793 (0)***5 per cent 4.800 5 per cent 5.080DlnGNSt5.271 (1)***10 per cent 4.580 10 per cent 4.820Dln(ngd)t 3.367 (2)**Notes: *** and** denoterejectionat the1and5per cent signicancelevels,respectively.

Thecritical values obtained from MacKinnon, Haug, and Michelis (1999) are used to testfor cointegration.2For the case of small samples, the results of Monte Carlo simulation byAbeysingheandTan(1999) revealedthat theOLSestimator is relativelymorerobust thantheother velong-runestimators suggestedbyJohansen(1988),Bardsen(1989), PhillipsandHansen(1990), EngleandYoo(1991)andStockandWatson (1993).C.F.

Therefore, theOLSestimator isappropriate for our study with the limited sample size. Panel B ofTable 3 shows the estimated long-run coefcients, whereas Panel Cof Table 3 shows the estimated short-run coefcients of the vectorerror-correctionmodel (VECM).3Fromtheresults, we ndthattourism, political stability, savings and ln(ngd)t are statisticallysignicant at the 1 per cent level in the long-run. In the short run,only political stability is insignicant while the rest of the variablesare statistically signicant at the 1 per cent level. Specically, theresultsindicatethattourismhasapositiveimpactoneconomicgrowth in both the short-run and the long-run. A 10 per cent in-creaseinpercapitareal tourismreceipts, onaverage, wouldin-crease per capita real GNP by 0.9 per cent and 1.4 per cent in theshort-run and in the long-run respectively. In summary, these re-sultsindicatethat tourismcouldstimulateMalaysia'seconomicgrowth, thus supporting the tourism-led growth hypothesis.Next, we further attempt to conrm the validity of the tourism-led growth hypothesis in Malaysia using the Granger causality test.Since the system-wide JohanseneJuselius cointegration resultsshows the presence of cointegration, the Granger causality test isconducted in the VECM framework to capture both short-run andlong-runcausalities. Table4reports theresults of theGrangercausality test. For the short-run, wend that the Likelihood Ratio(LR) test statistic rejects the null hypothesis that tourism does notGranger-cause economic growth and also the null hypothesis thateconomicgrowthdoesnotGranger-causetourism. Theseresultsthus indicate that tourismand Malaysia's economic growthGranger-cause each other (i.e. bi-directional causality) in the short-run. Turning to the long-run causality, wend that the one periodlagged error-correction term(t1) is statistically signicant at the 1per cent level when economic growth is the dependent variable.However, when tourismis the dependent variable, we nd that t1becomes insignicant at even 10 per cent level. Hence, based uponthe signicance of the t1 term, we are able to conclude that thereisauni-directional causalityrunningfromtourismtoeconomicgrowth in Malaysia in the long run. In light of all thesendings,the tourism-led growth hypothesis is well supported by theMalaysian experience. Tourismcould be an effective catalyst for thegrowth of the Malaysian economy. This is contrary to the ndings ofNanthakumar et al. (2008) and Kadir et al. (2010), but consistentwith those of Lau et al. (2009), Lean and Tang (2010), Othman et al.(2012) and Tang (2013) though it must be borne in mind that theseearlier studies are methodologically weak.5. Concluding remarksUsingamultivariatemodel derivedfromtheSolowgrowththeory, we attempt to analyse the impact of tourism on economicgrowth of Malaysia over the period of 1975e2011. The econometrictechniques involved in this study include tests for unit root, coin-tegration and Granger causality.As wefoundthat all thevariables areI(1), weappliedtheJohanseneJuselius cointegration test to determine the presence ofcointegration. Theresults of thetest suggestedthat Malaysia'seconomic growth, tourism, political stability, savings and popula-tion growth are cointegrated. Therefore, we estimatedthe short-run and long-run relationships between economic growth and itsdeterminantsinMalaysia. Remarkably, our ndingssuggestthattourism is positively related to Malaysia's economic growth in theshort-run and in the long-run. Similarly, the results of the GrangercausalitytestintheVECMframeworkalsoshowedthattourismGranger-causes economic growth both in the short-run and long-run. In conclusion, our empiricalndings support the tourism-ledgrowthhypothesis. TourismcanbereliedupontodriveMalay-sia's economic growth and development and hence, policy-makersshould pay greater attention towards promoting inbound tourism.This would also contribute to the structural diversication of theMalaysian economy and thus its resilience.SuchndingsonMalaysiahavegeneral applicabilitytoothercountriesaswell particularlythoseseekingfor newsourcesofgrowthanddevelopment.

Apart from these, they could advertise themselves as highlyinterestingtouristdestinationswithinternational televisionsta-tions. They could also try to cater to tourists from different regionsor countries by specically creating tourist spots that suit the variedtaste of differentnationalities.In a way,this couldmake touristsfeel at home while holidaying abroad.AcknowledgementThe earlier draft of this paper was presented at the InternationalConference on Business, Accounting, Finance and Economics (BAFE,2013): Paving the Way for Value Creation toward Sustainability, atUniversiti Tunku Abdul Rahman, Perak, Malaysia on October 4th,2013.We would liketo thank theanonymousreviewersand theeditorof TourismManagement, ChrisRyanfortheirconstructivecommentsandsuggestionsgivenontheearlierdraft.
