The New Tourism: the Growth of a New Middle Class and the Expansion of World Tourism Saud Choudhry† and Byron Lew‡ Trent University 1600 West Bank Drive Peterborough ON K9J 7B8 Canada ‡ corresponding author: [email protected] Abstract There has been an increase in tourism worldwide in the past decade, and most of that growth is due to growth in tourism from Asia. The growth of tourism from Asia is a net addition to world tourist flows; Asian destinations are not significant competitors for traditional destinations in Europe and the Americas. We estimate a gravity model of tourist flows and show that distance is still an important determinant of tourist flows, much more important than its role in directing commodity trade. We show that rising incomes will partly overcome the distance barrier, and will lead to a more integrated world of tourism linkages.

The New Tourism: the Growth of a New Middle Class and the Expansion of World Tourism After all that has been said of the levity and inconstancy of human nature, it appears evidently from experience that a man is of all sorts of luggage the most difficult to be transported. Adam Smith, Wealth of Nations Introduction The growth in tourism around the globe has been substantial over the last decade. The number of tourist arrivals has increased from 680 million in 2000 to almost 1 billion in 2010, an increase of almost 50% over the decade. The greatest growth has been among the countries of Asia. While travel by Europeans and North Americans declined over this period, travel by Asians has more than doubled.1 Tourist travel for the average person of an Asian country has become increasingly more important a component of consumption. With growth in the incomes among these countries has come a growth in the size of the middle-class. With an increase in wealth, and importantly, in leisure time, middle-class Asian consumers are now doing what middleclass consumers elsewhere in the West do with their leisure time ─they travel. The increase in the pool of potential tourists has led to an increase in demand for tourist destinations. While European destinations remain the most popular among tourists, an increasing share of world tourism reflects 1 Tourist departures did increase for these countries, peaking around 2007 and 2008. The increases to peak were smaller, approximately 20% from 2000. visits to tourist destinations in Asia. Tourist arrivals to European destinations have increased approximately 16% from 2000 to 2010, while arrivals to Asian destinations have increased almost 80% over the decade. The increase in tourist activity among the newly middle-class consumers of Asia has benefited the hospitality industries in both the traditional tourist destinations and in newly emerging destinations. While the Asian middle-class has increased dramatically, the average purchasing power of the new Asian middle-class is not yet as large as that of the western tourist. So these new tourists will choose locations nearer to home, and thus we observe an increase in the tourism industry in these countries too. We will quantity the factors that explain tourism using a modified gravity model. The gravity model is a useful tool in explaining the movement of commodities and factors of production by explicitly incorporating the frictions the inevitably arise in the movement of items. The framework has been used extensively to explain trade flows and trade costs (), the movement of migrants, and the movement of financial flows including foreign aid. Tourist flows are in essence trade in services, and therefore factors that explain trade flows will also explain tourist flows. We will show that while growth in income has increased the flow of tourists, there is a geographical pattern to the choice of tourist destinations, and it is determined in part by the country of origin. There is a general preference by tourists of particular countries to spend their leisure time in a few countries. As expected, distance is very important in capturing this tourism bias. We also discuss several other factors related to the implicit cost of tourism. We show that income does help reduce the effect of distance, but the effect persists. Background and Literature Review Tourist flows are assumed to respond to standard economic signals that influence demand for any good: price and income. Income is a characteristic of the individual tourist, so income differences across countries are hypothesized to explain differences in tourist outflows. We are characterizing not only the source countries, but the flows from source to destination. Characteristics of destinations will be important in attracting tourist from any given source country. There may also be country-pair specific frictions that impede tourist flows. The most obvious is distance. Given the characteristics of the bilateral flow data, we adopt a model used extensively in trade to explain movement of goods between countries. The analogy to trade is obvious; countries export their unique attributes by opening to tourism. We estimate a gravity model of tourist flows from the origin to destination countries. Gravity models are used extensively in trade, and have been defended theoretically as being consistent with demand theory. The basis for a gravity model is the maintained hypothesis that in a frictionless world where goods and information flowed without cost, each country's trade flows will be proportional to its share of world GDP. Observed deviations of trade flows from a proportionate share could reflect costs of trade (Deardorff, 1995). As tourism flows are only one component of the current account, we do not expect balance to be evident. Because countries export in order to import, trade will tend to balance in theory if we assume borrowing and lending reflect intertemporal trade. In contrast, countries are not equal as potential destinations. Consumers prefer diversity to uniformity and so will value variety. But tourists will have preferences and some countries will be natural tourist destinations. So a country's deviation from its share of world GDP will reflect two factors: the country's tourist characteristics, and tourism frictions. The examples of the use of gravity models in explaining tourist flows are few. Santana-Gallego (2010) assess the impact of common currencies on tourism. Their analysis is restricted to OECD origin countries. Keum (2010) examines South Korea and the bilateral tourism flows with 28 partner countries. While a useful example of the gravity model usage, it is a narrowly-focused topic and it is unclear if results are generalizable. There is an active debate over whether tourism enhances or is detrimental to growth. Examples of luxury tourist resorts in poor countries suggest few possible linkages. Empirical evidence is mixed, and often focuses on an individual country of a region, but is generally somewhat supportive of the hypothesis that tourism may enhance growth when specific country cases are examined (Ekanayake and Long, 2012; Arslanturk et al., 2011; Balaguer and Cantavella-Jorda, 2002; Kamas and Salehi-Esfahani, 1992). On the other hand, Sequeira and Campos (2007) do not find support for a link between tourism and economic growth using a long-run panel, even in subsamples divided by population, per capita incomes, and degree of tourism-specialization. Santana-Gallego et al. (2010) find that the growth effect of tourism increases with the income of the destination country though their sample is restricted to high income origin countries. Lee and Chang (2008) using time series techniques, in contrast, find that growth enhancing effects of tourism are stronger in non-OECD countries, though weak for Asia. That latter result may reflect the time period examined. Support is provided by Sequeira and Nunes (2008) who find a link between tourism and growth only for poor countries. Adamou and Clerides (2010) estimate the relationship between tourism receipts and growth allowing for a non-linear relationship, and find that tourism affects growth most for smaller, tourism-specialized countries while the effect diminishes as a country's tourism sector grows beyond a critical barrier of 20% of GDP. Effects of tourism on growth will be difficult to detect in a cross-section or panel because the data will invariably include the tourist destinations that cater to both the middle class and the wealthy. The linkage effects for tourist services provided to the wealthy may be limited as most of what is provided is likely to be imported, and local labour working at luxury resorts may well compete down the wages in exchange for the opportunity to received the better gratuities from well-heeled patrons. In contrast, linkages from the provision of basic tourist services are likely to be greater as more of the services provided will be sourced locally in order to offer services at modest prices. Therefore the growth of middle class tourism may well provide a bigger boost to incomes. That is an hypothesis to be explored elsewhere. Here we explore the growth of the middle-class tourist from the newly developing nations. Models and Data Tourist Flows We use data on bilateral tourist flows among all countries for the years 2005 through 2009 (UNWTO, 2012). There are several categories of tourist flows recorded by the World Tourism Organization (UNWTO). Our preference is for number of personal visits distinct from business or professional. The bilateral data do not always report this. Therefore we use total overnight visitor arrivals and adjust that value by the destinationcountry specific value for personal share of total arrivals for each year (Eilat and Einav, 2004, p. 1320). We illustrate some highly aggregated regional patterns of the bilateral tourist flows in Table T1. We have amalgamated the flows by World Bank region categories to illustrate the substantial home bias evident in the tourist flows. Destination regions are identified by row and source regions by column. The most important feature is the degree to which the size of intra-regional flows exceed inter-regional flows. Intra-regional flows are shown along the diagonal of each year's table. Inter-regional flows are all the off-diagonal values. [insert Table 1 about here] Europeans make up half of world tourists. The large majority of European tourist flows are within Europe. More than 80% of European tourists travel to European destinations. Tourist flows from East Asia are increasing, yet these tourists show an even greater home bias, with better than 85% choosing destinations within East Asia. Tourists from the Americas have modestly less home bias, but only a little less. Tourists from South Asia are the exception, but they are relatively few as a proportion of world tourist flows. Aggregation may be hiding regional differences, so we also examine the regional trade flows with a matrix of 26 regions defined by the UNWTO rather than just six.2 With this finer division, some different patterns emerge, but importantly, the patterns differ less for the regions with large tourist outflows: Northeast Asia and Western Europe. For tourists from the Northeast Asian countries of China, Japan and Korea, 2 Results not shown, but available from authors on request. more than 82% are visiting each other. For countries of Southeast Asia, that proportion is 68%. Europeans are a little more varied in their choice of destinations, but generally only within Europe. Over 80% of Southern and Western European tourists choose destinations in Europe, while over 70% of Northern European tourists also choose European destinations. North American tourists of Canada, the U.S. and Mexico, show a relatively diverse set of destination choices, but more than 50% still choose North America. The regions that show the least home bias other than South Asia tend to be small, and the flows are quite specific. For example, tourists from East and Central Africa visit Southern Africa. Tourists from the Caribbean visit North America. Tourists from South Asia also have a fairly specific set of destinations. About one-third visit the Middle East, another 20% visit Southeast Asia and 10% visit Northeast Asia, while 12% visit other South Asian countries. Tourists from Australia and New Zealand choose most widely and visit many different regions. But they do not constitute a large share of world tourist flows at just over 1%. To better capture the degree to which tourist flows are integrated by regions, we report tourism intensity indexes by aggregated regions as in Table 1 above. We calculate the index in the same way the trade intensity index is calculated. T ij = where x ij /x iw x wj / x x ij is tourist flows from country i to country j, tourist flows from country i, x iw is total x wj is total tourist flows to country j, and x are total world tourist flows. The index has a range from 0 to ∞, with numbers greater than 1 indicating an intense relation. [insert Table 2 about here] Table 2 reports tourism intensity indexes aggregated by region and averaged over all five years. The diagonal in the table represents intraregional tourist flows, and all values are very high with the exception of European intra-regional flows. While the index for European intra-regional tourist flows is greater than 1 and is therefore of high intensity, it is much smaller than all other intra-regional values reported in the table. So while Europeans also display a home bias, the bias is not as large relative to the size of European tourist flows. Of note are the very low values for the cells from Europe to East Asia and to the Americas. There are a few off-diagonal cells with tourism intensity index values greater than 1: flows from South Asia to the Middle East, bidirectional flows between the Middle East to Africa, from South Asia to East Asia, and from the Americas to South Asia. All other values are smaller than 1, and many are much smaller than 1. That the tourism intensity indexes for South Asia as a destination are relatively large is due more to the small denominator of the index rather than a large numerator. South Asian tourist flows are relatively small compared to others. Gravity Model The flows and tourism intensity index results discussed above illustrate the effect of distance and income given the apparent substantial home bias to the flows. In addition to distance and income, the flows will be determined by other travels costs, as well as price differences and other economic determinants. We estimate a gravity model of the flows to isolate the effects independent of income and other economic determinants. The basic gravity-model estimating equation is T ij =aY αi Y αj N βi N βj Aγi Aγj F δij i j i j i j (1) where Y is income as real per capita GDP, N is population, A is a vector of any other country-specific shift variables, and F are the trade frictions specific to each source country i and destination country j pair. We will estimate this in log-linear form so all variables are natural log-transformed unless specifically noted. The components of A and F are potentially significant (Prideaux, 2005). We discuss our choices as follows. The larger the countries, the greater the potential tourist flows between the two countries. We capture country size with GDP, population and geographical area.3 Note that GDP is included in the per capita GDP ratio. GDP per capita will also capture the effect of income on demand for the source country. Distance is used as a proxy for friction as the greater the distance the lesser the flow between two countries.4 In addition to distance, we consider several variables that would tend to mitigate the effect of distance and difference. We include indicators for countries that are contiguous and that share a common language---both official languages and most commonlyused languages. We also include indicators for a shared colonial experience. Following Eilat and Einav (2004, p. 1320), for price of tourism we use the ratio of the reciprocals of the PPP conversion factor representing the cost of a basket of goods in the destination country in terms of a basket of goods in the origin country. We hypothesize that the cheaper the basket of 3 4 These data are from World Bank's World Development Indicators database. Many other independent variables used in this study are from this source, and those that are not are otherwise indicated. Distance and other friction variables are taken from Mayer and Zignago (2011). goods in the destination country relative to the origin country, the greater will be the flow of tourists. Geography will be a factor in determining the relative cost of tourist inflows and outflows. We include a measure of the remoteness of each country, defined as the distance from a country to a population-weighted sum of the distances of all other countries. The more remote a country, the more costly it is for tourists to get to, so the lower the inflow of tourists. Symmetry would suggest this should work for tourist outflows as well. Inflation rates in source and destination countries could influence tourist flows to the extent that tourists book travel in advance. A landlocked country may also be more expensive for tourism. At a minimum, landlocked countries are not eligible to be cruise-ship destinations. In characterizing destinations we intend to capture only major differences. Variety will mean that many countries are potential tourist destinations. For variation in attractiveness we include the absolute value of a country's latitude, on the assumption that better climate is preferred. We include the absolute value of the latitude of the source country as we expect that countries at the extremes of latitude which experience greater seasonality may have greater tourist outflows and be otherwise less attractive destinations.5 We also include the length of coastline for a destination country as an indicator of potential as a tourist destination.6 Tourism will also suffer where tourists feel unsafe. To capture factors that keep tourists away, we use some indicators of potential violence and lawlessness. To capture institutional conditions, we include measures of political stability and rule of law. To capture direct risk to tourists, we 5 6 The latitude is not log-transformed. CIA World Factbook. include the homicide rate. Tourism will also be highly sensitive to conflict within a country so we include an indicator of conflict intensity (Themnér and Wallensteen, 2012).7 None of these variables are log-transformed. Tourism flows between any two countries may be influenced by the degree to which two countries are already economically engaged with each other. To capture this economic engagement, we include the value of trade between the two countries, separately including exports and imports.8 Many country-pairs have no reported trade, so we also include indicators differentiating between countries that trade with each other and those that do not.9 Our log-transformed base gravity-model is as follows: GDP it + ∑ c ln popit + ∑ d i ln areai + ∑ e i ln remote it pop it i∈ {o , d } i i ∈{o , d } i ∈{o , d } i∈{o ,d } + f PPP odt + ∑ g i ln inflationit + ∑ hi ruleofLaw it + ∑ j i politicStab it lnT odt =a + ∑ bi ln i ∈{o , d } i ∈{o , d } i∈{o ,d } + k conflict dt +l homRatedt + mod imports odt + m do imports dot + + ∑ (2)ni lat i i∈ {o ,d } ∑ p i landLock i+ q lenCoast d + r ln distance od + s contig od + ∑ v i comLang i ,od + ∑ w i colonial i ,od + ∑ τ t year t + u odt i∈{o ,d } i i t We estimate this model twice, with and without source country and destination country dummies. In order to fully account for any bias that 7 8 9 The UCDP/PRIO conflict intensity indicator ranges from 0 (no armed conflict) to 2 (intense armed conflict). Downloaded February 2012. Data from World Bank's World Integrated Trade Solution, downloaded December 2012. We do not log-transform the export and import values because of the presence of many zero-value observations. In empirical work it is common to substitute 0 for ln(0) on the assumption that 0 and 1 are generally not very different. In this case, the estimated coefficients are very sensitive to the value used for ln(0) even with inclusion of the dummy variables for country-pairs with no trade. may arise, we also estimate the model using source-destination pair dummies. The disadvantage to this specification is that all pair fixed effects, like distance, contiguity, etc. are embedded in the pair dummy variable and cannot be separately identified. We consider this specification our test version against which we can compare the other two. We are principally interested in the regional bias to tourist flows. We first posit the tourist behaviour of those at the income extremes. Those who are very wealthy will choose their tourist destinations for a variety of reasons reflecting personal taste, but distance is probably not of much consequence. The cost of transport is likely only a small proportion of their vacation expense. At the other end of the income distribution, those just barely middle class will likely be highly sensitive to all price differences and for this group distance may be very important. As with individuals, so too with countries. To quantify the potential decline in the effect of distance with income, we add an additional term into the regression in equation (2), the interaction of source per capita GDP times distance γ ln GDP ot ×ln distance od popot (3) and estimate the coefficient γ.10 The marginal effect of income on tourist flows is ∂ lnT od =b + γ ln distance od ∂(ln GDP o / pop o) o (4) where γ is the coefficient on the interaction term 10 We also estimated the model adding in the square of distance and its interaction with source per capita GDP. The results derived therefrom are unchanged regardless of the inclusion of these additional covariates. ln GDP ot ×ln distance od . The marginal effect of source GDP in our pop ot specification is then a function of distance, as shown in equation (4). We include the interaction term from equation (2) into two of the specifications, and estimate five different regression models.11 Our results are reported in Table T3. Regressions 1 and 2 do not include country dummies, regressions 3 and 4 include country dummies, and regression 5 is a fixed effects regression using country-pairs as the fixed effect. Standard errors in all regressions are estimated to be robust to clustering by country-pair. [insert Table 3 about here] Coefficient estimates on income of the destination country are quite stable across specifications. Coefficients on the origin-country income are stable for regression 1, 3 and 5, but in regression 2 and 4 they differ as origincountry income is interacted with distance. The interaction terms source income times distance are statistically significant. Other coefficients are less stable across different specifications. The country price lp3cons is negative and significant in regressions 3-5 as hypothesized. It is negative but insignificant in regressions 1 and 2, but these regressions are least preferred. The regressions use the income variables GDP per capita, so the effect of population is determined by the difference between the coefficients on lPop−lIncome , both for source and destination. In regression 5 we find that the effect of origin country population is negative and significant 11 The fixed effects regression embeds all bilateral pair effects into the fixed effect so no interaction term with distance is possible. while destination population is not statistically significant. Smaller countries tend to send more tourists abroad. We also include geographic area, so we can calculate the effects of population density as the sum lPop−lIncome−lArea . Population density for destination countries is positive and statistically significant while for source countries it is not statistically significant. Our preferred specification is the fixed effects regression 5 as it fully controls for unique attributes by country-pairs, but at the cost of embedding any time-independent bilateral-pair effects into the fixed effect. Some interesting results are the positive and significant coefficients on destination RuleOfLaw and the negative and modestly significant coefficients on destination HomRate and the noExports dummy variable. The coefficients on RuleOfLaw and HomRate capture the destination risk. Interestingly, political stability is positive and significant only in regressions 1 and 2. So we know that after controlling for fixed effects, political stability is less important than direct risk measures of rule of law and homicide rates. We hypothesized that exposure to trade would increase tourist flows, but we find that after controlling for the country-pair fixed effects in regression 5, all but the noExports are insignificant. The noExports coefficient is only significant at the 10% level, but it does indicate that while the level of trade does not matter to tourism—it seems to be determined by idiosyncratic country-pair effects—the presence of exports from origin to destination does increase tourist flows, while the presence of imports to origin from destination does not. The bilateral-pair variables present in regressions 1-4 are generally properly signed and statistically significant. Distance is negative and significant in all four specification. Note that regressions 1 and 3 can be compared and regressions 2 and 4 where distance is interacted with source income. Contiguous countries have greater tourist flows, as do countries with common languages. Countries with common colonial origins have greater tourist flows, as do countries that had a colonial relationship after 1945. Using the estimates from the model with country dummies and the interaction terms, we then plot the marginal effect of a source country's income on tourist flows as a function of distance, in Figure F1. The marginal effect of source country income on tourism is negative for short distances, distances less than about 60km. Tourist trips of short distances are less likely as incomes rise, so short distances are affordable for those from lower income countries. Those from wealthier countries are able to afford variety, and so will prefer to stray farther from home and make longer trips to see new places. [insert Figure 1 about here] For trips of distances ranging from about 60km through about 500km, the marginal effect of source country income is not statistically significant; the 95% confidence interval includes a value of zero. So we conclude income has no effect on tourism at these distances. For these medium-distance trips, tourists from rich and from poor countries are equally likely to make, given all other characteristics. For trips of greater distance, more than 500km, source country income has a positive marginal effect on tourist flows. The marginal effect is also increasing with distance. For longer distances, there are more tourist flows from wealthier countries, and the effect of wealth is increasing with distance. So tourists from wealthier countries are more likely to make long distance tourist trips.12 We are observing that distance affects who travels. For short distances, income correlates negatively with tourism flows, though it should be noted that there are very few observations for trips of this length. We see more clearly that income matters for tourist trips greater than 500km. These constitute the large majority of the observations. The strong intra-regional flows we observe are consistent with this result. While we draw this conclusion using model 4, we can also comment on the results from the fixed effects regression. While much of the explanation of tourist flows in the fixed effects model is in the countrypairs, the R2 is very low, we conclude that the country-pair effects are not simply random, but rather depend on distance between the origin and destination countries. Conclusions The increasing wealth of Asia and the Middle East has given rise to new tourists. The resultant tourist flows illustrate that tourists are highly sensitive to price, and distance matters greatly. This has created new intraregional tourist flows, and the growth of a new tourist industry in those parts of the world where the new middle class is beginning to consume more. This new tourist flow is complementary to the already existing patterns of tourist flows from Europe and North America. As incomes grow, we predict that the intra-regional bias to tourist flows will be partly mitigated. How far this will go remains to be seen. Transport 12 Inclusion of the square of ln distance with and without its interaction with source per capita GDP has no material effect on the marginal effect of income on tourist flows. That means there is no tendency for the effect of income to level off at a certain distance. The linear trend is robust. costs are highest in the services sector, so it is not surprising that we find distance and other tourists costs very important. That means in the near future, tourism operators will not face competition for their market. But for the regions of the new middle class, opportunities for tourism abound. As incomes in Asia continue to rise, demand from these new tourists for destinations farther away will increase. But even with rising incomes, tourist flows will likely continue to display the home bias that we observe. We see a possible benefit to income growth from the regional expansion of tourism demand. This demand is particularly important because it is demand from tourists of more moderate means; the services they demand will tend not to be luxurious. Instead we see opportunity for the small hotelier providing adequate accommodation and for food service of the practical variety. The linkage effects to growth are likely to be of more importance compared to the services provided in luxury resorts in poorer countries in tropical destinations.
