Abstract
This paper examines the relationship between tourism and trade that might have evolved in the development of
Malaysian economy by using cointegration and causality tests. All analyses have been conducted with quarterly data of
international tourism receipts, exports, imports and total trade of Malaysia, over the period of 1995:1 through 2006:4.
The results of the unit root tests indicate that the data are stationary in first-difference and not in level. The results of the
JJ co integration test however, show that all the series are not cointegrated in the long run, hence, long-run equilibrium
did not exist between all the series. Using Granger-causality tests the study found that there is one-way causal effect
(unidirectional causality) running from exports to international tourism receipts at 5% significance level. The causality
test also shows a one-way causal effect running from imports to international tourist receipts at 5% significance level
and total trade to international tourism receipts at 10% significance level. This leads to a conclusion that increase in
total trade, exports and imports will cause growth in the tourism sector, which means that most of tourist arrivals are
related to business tourism. Therefore, to increase and sustain in the growth of tourism sector, future economic policy
should focus more on tourism and trade related, in order to generate more foreign exchange earning to Malaysia.

1. Introduction
Tourism can be classified into several distinct categories. They would include holiday travel, visiting friends and
relatives (VFR), business travel, health treatment, shopping, conference, incentive travel, official mission, education,
sport and others travel (Malaysia Tourism Promotion Board, 2004). Despite uncertainty in the global economic
environment, Malaysian tourism industry continues to perform favorably as reflected in the growth of tourist arrivals
and tourist receipts. The share of tourism revenue in total earnings of the services account of the balance of payments
increased from 32.7% in 2000 to 43% in 2005. Taking into account the inflow of foreign tourists and outflow of local
residents traveling abroad, the net contribution by tourism improved from RM11.2 to RM18.1 billion for the same
period. The development in tourism also contributed positively to the expansion of activities in other subsectors,
particularly the hotel, travel and tour industry, retail and restaurants as well as transport.
During 2000-2005, total trade expanded at an average rate of 7.2% per annum from RM684.7 billion in 2000 to
RM967.8 billion in 2005. Gross exports grew at an average rate of 7.4% per annum to RM533.8 billion in 2005. With
this performance, Malaysia ranked 18th largest exporter, contributing 1.5% of world export. While gross imports
increased at an average rate of 6.9% per annum to RM434.0 billion in 2005 (Ninth Malaysia Plan, 2006-2010). The
pattern of trade and tourism data in Malaysia provides cursory evidence that there is a long-run relationship between the
two sectors (Figure 1). However, the significance of such a relationship can only be proven by undertaking appropriate
studies.
Is there a relationship between international trade and tourism? If so, how? This question can be taken to a more
disaggregated level of inquiry. Evidently, international business creates export sale and/or import purchase. Successful
business trips will further lead business travel flows and there will be a series of externality effects on both trade and
tourism. Increase business travel may also increase holiday and other travel when friends and relatives seeking
adventure and recreation accompany business travelers (Kulendran and Wilson, 2000). Earlier studies by Kulendran and
Wilson (2000) lend empirical support to the relationship between tourism and trade. They analyzed the direction of
causality between different travel and trade categories for Australia and its four major trading partners, using time series
data. The study provides empirical evidence in supporting the idea that there is a long-run relationship between
international trade and international travel. Using the same approach, Khan and Lin (2002) investigated the relationship
between international trade and tourism for Singapore and its major trading partners. Although the results tend to differ

across countries, the study provides strong support for a systematic relationship between business travel and total trade.
Furthermore, the causality between travel and trade could run both ways, whereby business arrivals influence trade or
vice versa. However, holiday or pleasure travel, is found to be somewhat unrelated to trade.
Other categories of tourism such as VFR, health treatment, shopping, conference, incentive travel, official mission,
education, sport and other travels can also influence trade because tourists may demand certain types of product that are
produced or otherwise in that country. If they demand products that are not produced in that country, therefore it has to
be imported, this may lead to an increase in import. On the other hand, if tourists purchase products that are produced
locally, this will increase income of that country. Higher trading volumes countries are likely to be more open
economies and more developed in tourism industry. Therefore, expansion in the tourism industry will also lead to an
expansion in the trade when demand for tourist commodities increase (Khan and Lin, 2002). According to the World
Tourism Organization (UNWTO) the number of international tourist arrivals recorded worldwide grew by 5.4% and
exceeded 800 million for the first time in 2005 (ever from 766 million in 2004). Although growth was more moderate, it
was still almost 1.5 percentage points above the long-term average annual growth rate of 4.1%. Tourist arrivals to
Malaysia reached its target of 16.4 million tourists by the end of December 2005 exceeding 15.7 million tourists in 2004.
From the 16.4 million tourist arrivals in 2005, Malaysia received RM32.0 billion in foreign exchange earnings,
representing an increase 0f 7.8% from 2004.
In terms of traveling pattern, holiday arrival, which represented 71.2% of total arrivals in 2005, had declined by 3.7% as
compared to 2004. While tourists who came for business, shopping, conference, official mission and sport has increased
by 2.4%, 0.1%, 0.4%, 0.3% and 0.9% respectively (see Table 1). This is in conjunction with aggressive promotions
made in new and non-traditional markets, particularly in West Asia as well as increasing number of international
conferences and exhibitions held in the country (Economic Report, 2005/2006). Average per capita expenditure also
registered an increase of 3.2% from RM1,888.20 to RM1,944.70. Tourists spent mostly on accommodation (33.5%),
followed by shopping (20.8%), food and beverage (19.9%), transportation (11.6%), and entertainment (4.0%). From the
distribution of items purchased in 2005, clothes/textiles/bag constituted more than 50% from overall shopping items.
The second most favorite items was handicraft/souvenir at 45.5%. Items such as liquor, DVD/VCD/CD/Cassette, toys,
cigarette/cigar, gold/jewellery, electrical/electronic appliances and others were consumed below 10% in 2005.
Besides, total trade consists of exports and imports. ASEAN accounted for 26.1% of Malaysia’s exports and 25.5% of
imports in 2005, while Japan 9.4% of exports and 14.5% of imports; Australia 3.4% of exports and 1.9% of imports; the
U.S 19.7% of exports and 12.9% of imports and the U.K 1.8% of exports and 1.5% of imports. Internationally, tourism
represents an important source of foreign exchange earnings and it has been suggested that the potential contribution to
the national balance of payments (Oppermann and Chon, 1997). Although tourism is a powerful tool for balance of
payments adjustments, its impact may vary according to countries. In the developed countries, the earnings from
international tourism could make a significant contribution to the balance of payments in general, and the invisible
account in particular. However, for many developing countries with a limited industrial sector and dependence on
international aid, tourism plays a significant role in securing foreign exchange, creating employment and attracting
overseas investment (Sharpley, 2002). As indicated by the UNWTO and International Monetary Fund (IMF) data,
international tourism is the top export earning sector in the world, exceeding both the automobile industry and the
chemicals industry, and together with international fare receipts represents about 8% of total export earnings on goods
and services worldwide. Tourism is also one of the top five export earning sectors for 83% of countries in the world,
and the main source of foreign currency for at least 38% of the countries. In the 1980s, international tourism receipts
grew faster than world trade (commercial service and merchandised exports).
Despite the fact that tourism is a major important sector for the world’s economy for many countries, it is one of the
largest single employers and exporting service sectors; however, to our knowledge there are very few attempts to
investigate the relationship between tourism and trade. In addition, literature on relationship between tourism and trade
in the developing countries is completely lacking. The present study seeks to investigate the relationship between
tourism and trade that might have evolved in the process of development of Malaysian economy by using cointegration
and causality tests. The results of the study seem to have important implications for Malaysia’s policy concerning
tourism and trade. If we can prove that, there is a long-run relationship between international trade and tourism, future
economic policy should focus more on tourism and trade related, in order to generate more foreign exchange earning to
Malaysia.
2. Methods and materials
All analyses were conducted with quarterly (time series) data of international tourism receipts, exports, imports and
total trade (on real terms) of Malaysia, over the period of 1995:1 through 2006:4. These series were obtained by
dividing the nominal series by the consumer price indices (2000:Q1=100). In this study, the tourism and trade
hypotheses to be tested are as follows, namely: (a) does international tourism receipts cause export. (b) does exports
cause international tourism receipts? (c) does an international tourism receipt cause imports? (d) does imports cause

international tourism receipts? (e) does international tourism receipts cause total trade? (f) does total trade cause
international tourism receipts? Therefore, with this tourism and trade hypotheses, attempts were made to test and search
for evidence of existence of relationship.
Firstly, before estimating the co integration and VAR, it is required to examine the stationarity of the variables.
Stationarity means that the mean and variance of the series are constant through time and the auto covariance of the
series is not time varying (Enders, 2004). Therefore, the first step is to test the order of integration (I) of the variables.
Integration means that past shocks remaining undiluted affects the realizations of the series forever and a series has
theoretically infinite variance and a time-dependent mean. For the purpose of this study, we use tests proposed by
Dickey and Fuller (ADF, 1979, 1981), Phillips and Perron (PP, 1988) and Kwiatkowski, Phillips, Schmidt and Shin
(KPSS, 1992) in testing the properties of unit root for all variables used. If all of the series are non-stationary in levels,
it should be stationary in first difference with the same level of lags. For appropriate lag lengths, we use the Akaike
Information Criterion (AIC) and Schwartz Bayesian Criterion (SBC).
The ADF test takes the following form:
p
ǻYt = Įo + įT+ȕYt-1 + ș
iǻYt-i + ȝt (1)
i=1
The ADF auxiliary regression tests for a unit root in Yt, namely the logarithm of total tourism receipts, total trade,
exports and imports. T denotes the deterministic time trend and ǻYt-i is the lagged first differences to accommodate a
serial correlation in the error, ȝt. While, Į,į,ȕ, and ș are the parameters to be estimated.
Meanwhile, the Phillips-Peron (PP) test is shown by the equation below.
ǻYt = ȝ + ȡYt-1 + İt (2)
The PP test is used because it will make a correction to the t-statistics of the coefficient from the AR (1) regression to
account for the serial correlation. The PP test is a test of the hypothesis ȡ=1 in the equation 2. But, unlike the ADF test,
there are no lagged difference terms. Instead, the equation is estimated by OLS and then the t-statistics of the ȡ
coefficient is corrected for serial correlation in İt.
In the first two methods, the unit root hypothesis corresponds to the null hypothesis. If we are unable to reject the
presence of a unit root, meaning that the series are integrated of order one. However, Kwiatkowski, Phillips, Schmidt
and Shin (1992) argued that not all series for which we cannot reject the unit root hypothesis are necessarily integrated
of order one. To circumvent the problem that unit root tests often have low power, they offer an alternative test, which
is KPSS test. In the KPSS test, stationarity is the null hypothesis and the existence of a unit root is the alternative. The
KPSS test is shown by the following equation
yt = x'tȕ + μ (3)
The LM statistics is given by:
T
LM = S2t/ıİ2 (4)
t=1 ˆ
where, ıİ2 is an estimator for the error variance. This latter estimator ıİ2 may involve corrections for autocorrelation
based on the Newey-West formula. In the KPSS test, if the null of stationarity cannot be rejected, the series might be
cointegrated. After identifying the order of intergration, we then use the Johansen (1988, 1991), and Johansen and
Juselius (1990) Full Information Maximum Likelihood (ML) technique to determine whether there is a long-run
relationships (cointegrating) between the various series. If there is a cointegration between two variables, there, exists a
long-run effect that prevents the two series from drifting away from each other and this will force the series to converge
into long-run equilibrium.
The study further explores the relationship between the series by using Granger-Causality test to test for the bivariate
equation. Granger (1988) points out that if two series are cointegrated, then there must be Granger-causation in at least
one direction. A variable Xt Granger causes Yt, if Ytcan be predicted with better accuracy by using past values of Xt
with other factors held constant.
The Granger causality test involves estimating the following model:
p q
Yt = ȝt + Į
iYt-i + ȕ
iXt-i + İt (5)
i=1 j=1
Where ȝtdenotes the deterministic component and İtis white noise. Meanwhile, the null hypothesis can be tested by
using F-test. When the p-value is significant, the null hypothesis of the F-statistic is rejected, which implies that the first
series Granger-causes the second series and vice versa.

In this study, we used quarterly data of international tourism receipts and total trade for Malaysia spanning from 1995:1
to 2006:4. The data used in this study are obtained from Malaysian Tourism Promotion Board (Planning and Research
Division), Annual report of Bank Negara Malaysia (the Malaysian Central Bank), the Statistical Yearbook (various
issues) published by the Malaysian Department of Statistic and the IMF International Financial Statistics Yearbook.
3. Results and discussion
In order to estimate the long-run relationship between the variables using the cointegration approach, first, we need to
examine the stationary properties of the time series data, to avoid spurious regression. Tables 1, 2, and 3 present the
stationarity test results of international tourism receipts, exports, imports and total trade in level and first differences,
using ADF, PP and KPSS tests. The results of the unit root tests indicate that we could not reject the null hypothesis of
the unit root at 1 per cent and 5 per cent critical value. However, the null hypothesis is rejected at 1 per cent critical
value, when we test on the first-difference. This suggests that the data are stationary in first-difference and not in level.
Having found that the variables are I(1), we proceed with the cointegration tests in testing for the cointegration between
the variables, which are non-stationary in level but stationary in first-difference. The Johansen and Juselius (JJ)
approach is employed to test whether there is a long- run relationship between the selected variables. The results of the
JJ co integration test however, shows that all the series are not cointegrated in the long-run. In a simple word, long-run
equilibrium did not exist between all the series.
In order to examine the causal relationships as well as directions of the series, then we run the Granger causality tests,
which can be implied by the non-cointegrating series. The results of Granger-causality tests as reported in Tables 4 and
5 indicate that there is one-way causal effect running from exports to international tourism receipts at 5% significance
level. The causality test also shows a one-way causal effect running from imports to international tourist receipts at 5%
significance level and total trade to international tourism receipts at 10% significance level.
4. Conclusion
This study attempts to investigate the relationship between tourism and trade that might have evolved in the
development of Malaysian economy by using cointegration and causality tests. The findings of the study indicate that
there is a one-way causal effect (unidirectional causality) between all the series. Subject to possible caveats of the study,
the following are some important policy implications for Malaysia in terms of tourism and trade that can be drawn from
the findings. It seems that increase in total trade, exports and imports will cause growth in the tourism sector, which
means that most of tourist arrivals are related to business tourism. Hence, future economic policy should focus more on
tourism and trade related, in order to generate more foreign exchange earning to Malaysia. Besides, in order to increase
and sustain in the growth of tourism sector, more attention should be given to the business tourism since this category of
tourism has shown higher growth rate (see Table 1). Furthermore, Malaysia Tourism Promotion Board should also
focus on MICE (Meetings, incentives, conferences and Exhibitions) market because this category of tourism also shown
a growth as well as relatively a higher value added market.

This study aims to investigate the relationship between international tourism and total trade, including exports and imports, for the twenty most visited countries. In order to accurately assess the relationship, the study employs the Emirmahmutoglu and Kose (2011) causality analysis, which accounts for cross-sectional dependency and heterogeneity. The empirical results show a unidirectional causality running from total trade, exports, and imports to international tourist arrivals for Germany, India, Mexico, and the Netherlands. Conversely, the causality runs from international tourist arrivals to total trade, exports, and imports for Portugal, Russia, and Spain (except imports). Additionally, a bidirectional causality link between international trade and tourism is found for China, indicating that both tourism and trade mutually reinforce each other. These results highlight the importance of considering the direction of causality in the relationship between tourism and trade, and developing targeted policies that take into account the unique characteristics of each country.
... They concluded that bi-directional relationship between CPI and international tourist arrivals and between CPI and GDP, suggesting that economic aspects leads to Malaysia's tourism industry. Kadir et al., [18] investigated the co-integration and causality relationship using quarterly data of total trade, international tourism receipts, total exports and imports. The results revealed that total trade drives tourism growth. ...

Tourism demand leads to economic growth, but empirical studies of tourism sector performance on economic risk nexus have been quite scant, especially under climate change context. This paper studies the influence of tourism firm financial performance on volatility and growth in Malaysia. Three types of firm volatility are measured by standard deviation, GARCH(1,1) and EGARCH models. The effect of tourism firm performance on volatility of firms' stock return and economic growth under climate change and environmental hazards condition is further examined. This study focuses panel data in Malaysia from years 2010 until 2021. Data were content-analyzed and coded into weather types, firm performance and stock return volatility. Climate change data consist of temperature extremes, the intensity of rain events, rain days, floods and extreme events. Environmental hazards data include carbon dioxide emissions (CO2), greenhouse gas emissions (GHG) and air quality index (AQI). The results statistically reveal that (i) financial performance is a significant factor in explaining the volatility of tourism firms and economic growth (ii) better financial performance contributes to economic growth under climate change context (iii) tourism firm financial performance induces environmental hazards, especially CO2 and thus affects the tourism firms' financial risk in Malaysia. Results from this study are important to policymakers who should spare no effort to mitigate the effect of climate change in the context of tourism performance and economic risk. This study provides detailed insights into the sensitivity of tourism firm performance on economic risk, and their current ability to deal with climate change issue. http://www.ijtef.com/index.php?m=content&c=index&a=show&catid=132&id=1139
... Ancak, uzun dönemde varlığı tespit edilen bu etkinin zayıf olduğunu (Lorde vd., 2013), turizm gelirlerinin cari açık problemini kısmi olarak çözebileceğini (Narayan vd., 2021); hatta kısa dönem için turizmin cari dengeye olumsuz yansıdığını ileri süren (Uslu, 2020) analizler de bulunmaktadır. Dış ticaret açısından ise uzun dönemde sadece turizmin dış ticarete değil, dış ticaretin de turizm sektörüne etkileri olduğunu (Kadir & Yussof, 2010;Surugiu & Surugiu, 2011;Kumar vd., 2019) ileri sürmek de mümkündür. Bu yüzden, sektördeki talebin ve bunun sonucundaki gelirlerin uzun dönemde cari açığı finanse etmek için kullanılıp kullanılamayacağı, farklı ülke ve bölgeler için araştırılmaya değerdir. ...

Bu çalışma, Akdeniz Havzası ülkeleri için cari işlemler dengesi ve uluslararası gelen turist sayısı arasındaki ilişkiyi incelemektedir. Araştırma, Akdeniz Havzası ülkelerinde turizmin geliştirilmesinin cari açığın uzun dönemli finansmanında politika aracı olarak kullanılabileceği hipotezini test etmektedir. Veri setinin mevcudiyetine bağlı olarak, 1998-2019 döneminin analiz edildiği çalışmada kontrol değişkenleri olarak; gayri safi yurt içi hasıla, nominal döviz kuru ve enflasyon oranı yer almaktadır. Yatay kesit bağımlılığı ve heterojenlik sorunlarının tespit edildiği panel veri analizinde; Westerlund’un (2008) geliştirmiş olduğu Durbin-Hausman eşbütünleşme testi üzerinden, seriler arasındaki uzun dönemli ilişki incelenmiştir. Ayrıca Genişletilmiş Ortalama Grup (Augmented Mean Group, AMG) tahmincisiyle; uluslararası turist sayısı ve kontrol değişkenlerinin, cari işlemler dengesi üzerindeki etkileri ortaya konulmuştur. Elde edilen ampirik bulgular, söz konusu değişkenler arasında uzun dönemli bir ilişki olduğunu ima etmektedir. Uluslararası turist sayısının, cari işlemler dengesi üzerinde pozitif yönde etkisi vardır. Nominal döviz kuru ve enflasyonun ise cari işlemler dengesini negatif yönde etkilediği tespit edilmiştir. Kısacası, bulgular Akdeniz Havzası’nda turizmin gelişmesinin ekonomik ve sosyal açıdan önemli olduğunu göstermektedir. Çünkü turizm sektörü cari dengeyi olumlu yönde etkileyerek bu ülkelerin ekonomik istikrarına katkıda bulunmaktadır.

This study analyzes the dynamic relationships between tourism, gross domestic product (GDP) per capita, exports, imports, and carbon dioxide (CO2) emissions in five South Asian countries. A VAR-based Granger causality test is performed with time series data from Bangladesh, India, Nepal, Pakistan, and Sri Lanka. According to the results, both bidirectional and unidirectional relationships among tourism, economic growth, and carbon emissions are investigated. Specifically, tourism significantly impacts GDP per capita in Pakistan, Sri Lanka, and Nepal, yet it has no effect in Bangladesh or India. However, the GDP per capita shows a unidirectional relationship with tourism in Bangladesh and India. The unidirectional causal relationship from exports and imports to tourism in the context of India and a bidirectional relationship in the case of Nepal. In Pakistan, it is observed that exports have a one-way influence on tourism. The result of the panel Granger test shows a significant causal association between tourism, economic growth, and trade (import and export) in five South Asian economies. Particularly, there is a bidirectional causal relationship between GDP per capita and tourism, and a significant unidirectional causal relationship from CO2 emissions, exports, and imports to tourism is explored. The findings of this study are helpful for tourism stakeholders and policymakers in the region to formulate more sustainable and effective tourism strategies.
... He also finds that bilateral trade, along with immigration, border, and distance between Portugal and its country partners, is a key driver of tourism in Portugal, based on static and dynamic. Using Granger-causality, Kadir and Jusoff (2010) also find a unidirectional causality running from exports, imports, and total trade to international tourism receipts for the case of Malaysia. Lee's study (2012) examines the short-and long-term dynamic interactions between exports, imports, international tourism, and economic growth in Singapore using annual data from 1980 to 2007. ...

Vietnam's tourism industry has been one of the economy's key growth drivers for years. This study examines the relationship between international tourist arrivals, bilateral trade, and income in Vietnam by applying a cointegration model with the panel data of Vietnam and its major global tourism markets. The results show that export and per capita income significantly influence Vietnam's international tourist arrivals from 2008 to 2019. The study also uses causality techniques to test for the direction of causality and found a two-way causal effect from exports and income to international tourist arrivals. These findings suggest that future economic policy should focus more on tourism and trade-related to sustain the growth of the tourism industry and generate more foreign exchange earnings for Vietnam.

Tourism has become an important sector in the economy over recent decades, but the impact of tourism on economic growth is still debated. The purpose of this paper is to investigates the long-run relationship between tourism and economic growth in ASEAN countries as well as the causal linkages between them. This study uses panel Autoregressive Distributed Lag (panel ARDL) and data from the World Tourism Organization and the World Development Indicator. The results suggest that tourism has significant and positive impact on economic growth in the long run. Furthermore, the results also indicate that there is bidirectional causality between inbound tourism and economic growth.
... However, the authors decided that the contribution of the tourism towards an economy of a nation can not be disclaimed as this industry may have indirect impact towards economic growth as such generally documented in the literature reviews. In Malaysia also, Kadir and Jusoff [40] approved that an increase trade variables such as: whole trade, exports and imports will have a influence for growth in the tourism activity and thus economic strategy should focus on enhancing tourism sector. ...

This research empirically investigates impact of tourism on employment and economic growth in case of Uzbekistan. Using time series empirical techniques the study examines long-run and short-run relationship between international tourism arrivals, employment and real GDP in Uzbekistan by using Autoregressive Distributed Lag model for the period from 1991 to 2020. The results attained from the analyses show that there is a positive connection between tourism, employment and economic growth in Uzbekistan. Furthermore, the results show that there is unidirectional Granger causality flow between tourism and economic growth in Uzbekistan. The main benefit of the approach is that, apart from providing robust results in small sample sizes, it needs no a priori information about the integration properties of the variables. Moreover, growing number of international tourists will thus have a positive impact on Uzbekistan economy and employment. Our findings suggest that Uzbekistan can enhance its economic growth by strategically supporting the tourism sector in the country. Keywords: Tourism, employment; economic growth; Autoregressive Distributed Lag model; Uzbekistan

Travel sanctions are a strategic diplomatic tool that are generally preferred by sanctioning countries to other invasive actions because they can reduce or avoid casualties and losses and achieve policy goals. The present study investigates the relationship between travel sanctions and the number of international tourist arrivals by employing a gravity model from 1995 to 2015. The empirical results reveal that imposing international travel sanctions leads to a decrease in the number of tourist arrivals. Moreover, sanctions between developed countries have more influential effects than those between developing countries.

In this study, the relationship between tourism development and trade in 12 sub-Saharan African (SSA) countries is examined during the period 1995-2019. Three proxies of trade are used, namely the total trade, total exports, and total imports of goods and services to examine this linkage, thereby leading to three separate model specifications. A wide range of modern econometric techniques were also employed to examine the relationship between the various proxies of trade and tourist arrivals. These include (i) cross-sectional dependence tests based on Breusch and Pagan (1980) LM, Pesaran (2004) scaled LM, Baltagi et al. (2012) bias-corrected scaled LM, and Pesaran (2004) CD; (ii) an ECM panel cointegration test based on Westerlund (2007); and (iii) a heterogeneous panel causality model based on Dumitrescu and Hurlin (2012), among others. Using the dynamic ordinary least squares (DOLS) and the fully modified ordinary least squares (FMOLS), the study found that, overall, international tourism has a positive and significant impact on trade in SSA countries. This finding is also corroborated by the heterogeneous Granger causality test, which found a distinct unidirectional causal flow from international tourist arrivals to trade. The study, therefore, recommends that SSA countries should implement policies aimed at promoting international tourism in order to increase their international trade and boost their overall trade balance.

Let n observations Y 1, Y 2, ···, Y n be generated by the model Y t = pY t−1 + e t , where Y 0 is a fixed constant and {e t } t-1 n is a sequence of independent normal random variables with mean 0 and variance σ2. Properties of the regression estimator of p are obtained under the assumption that p = ±1. Representations for the limit distributions of the estimator of p and of the regression t test are derived. The estimator of p and the regression t test furnish methods of testing the hypothesis that p = 1.

This article discusses tourism development theories with respect to their spatio-temporal implications in the Third World. They are all found to be inadequate in explaining the spatial occurrence and temporal development of tourism in developing countries. This is largely due to a lack of differentiation of tourism activity into different sectors. In response, the proposed model of “tourist space in developing countries” acknowledges the influence of the existing social and economic structures in these countries at all stages of tourism development, differentiates the tourism industry into two sectors, and recognizes the spatial segregation and different economic impacts of the sectors.RésuméL'espace touristique aux pays en voie de développement. L'article examine des théories de développement touristique et leurs implications spatio-temporelles au Tiers-Monde. On trouve qu'aucune des théories ne suffit pour expliquer les circonstances de l'espace et le dévelopment temporel aux pays en voie de développement. Cette insuffisance vient du fait que ces théories ne distinguent pas les différents secteurs de l'activité touristique. Cet article propose donc un modèle qui intg̀re l'influence des structures sociales et économiques existantes à toutes les phases du développement du tourisme, qui différencie l'industrie touristique en deux secteurs et qui reconnaît la ségrégation spatiale et les effets économiques différents des deux secteurs.

We consider a nonstationary vector autoregressive process which is integrated of order 1, and generated by i.i.d. Gaussian errors. We then derive the maximum likelihood estimator of the space of cointegration vectors and the likelihood ratio test of the hypothesis that it has a given number of dimensions. Further we test linear hypotheses about the cointegration vectors.The asymptotic distribution of these test statistics are found and the first is described by a natural multivariate version of the usual test for unit root in an autoregressive process, and the other is a χ2 test.

The paper considers three separate but related topics. (i) What is the relationship between causation and co-integration? If a pair of I(1) series are co-integration, there must be causation in at least one direction. An implication is that some tests of causation based on different series may have missed one source of causation. (ii) Is there a need for a definition of ‘instantaneous causation’ in a decision science? It is argued that no such definition is required. (iii) Can causality tests be used for policy evaluation? It is suggested that these tests are useful, but that they should be evaluated with care.

This paper investigates, for the first time, whether there is a relationship between international trade and international travel flows using time series econometric techniques. Using data for Australia and four important travel and trading partners, the USA, the UK, NZ and Japan, the paper tests three specific hypotheses: that business travel leads to international trade; that international trade leads to international travel; and that international travel, other than business travel, leads to international trade. Using cointegration and Granger-causality approaches the paper finds support for prior beliefs that there is a relationship between international travel and international trade, and suggests that this may be a fruitful area for further research.

This paper gives a systematic application of maximum likelihood inference concerning cointegration vectors in non-stationary vector valued autoregressive time series models with Gaussian errors, where the model includes a constant term and seasonal dummies. The hypothesis of cointegration is given a simple parametric form in terms of cointegration vectors and their weights. The relation between the constant term and a linear trend in the non-stationary part of the process is discussed and related to the weights. Tests for the presence of cointegration vectors, both with and without a linear trend in the non-stationary part of the process are derived. Then estimates and tests under linear restrictions on the cointegration vectors and their weights are given. The methods are illustrated by data from the Danish and the Finnish economy on the demand for money. Copyright 1990 by Blackwell Publishing Ltd
