Having recognized the importance of tourism to economic growth, most international organizations have begun to argue that tourism growth can influence, as well, the economic and sociocultural development of society. However, recently, a new approach that criticizes the relationship between both dimensions has begun to be developed; suggesting that this is not an automatic relationship. In this context, the aim of this study is to determine whether the economic growth experienced in some countries as a result of the expansion of the tourism activity over the last two decades influences an increase in the level of economic development. To that end, a sample of 144 countries has been used, which verifies that this relationship occurs, especially in more developed countries, which calls into question the conception of tourism as a driving force of economic development for the least developed countries, and even in developing countries.

The methodological bases are established for the design of a global composite index, the ST index, to measure tourism sustainability. Tourism sustainability is a fairly complex concept due to its latent, multidimensional and relative nature. A method based on factor loadings is proposed to construct a global tourism sustainability index. After comparing it with various theoretical approaches, the authors apply it to the Spanish system of environmental tourism indicators. The robustness of the proposed ST index is tested by calculating composite correlations between the Euclidean distances of different tourism destinations.

Sustainability has become an important strategic objective for tourism destinations worldwide. All analytical tourism competitiveness models make direct or indirect positive references to sustainability. It is accepted that sustainable tourism can reduce resource costs and help create market differentiation. Nevertheless, it has traditionally been considered that, short term, sustainability measures can reduce profitability and compromise competitiveness. Debates on the progress, implications, and practicality of sustainable tourism remain open. The relationship between economic sustainability, and environmental and sociocultural sustainability, is a central but largely unresearched area for tourism scholars, especially at the macro level. This study explores that difficult but essential area, using the World Economic Forum's empirical evidence from 128 countries, backed by the economic data search tool of the World Travel & Tourism Council. It demonstrates that progress in tourism sustainability does not affect a country's main economic tourism indicators in the short term, and does not constrain profitability and competitiveness. It also finds that sustainable tourism is not a luxury that only rich countries can afford, nor should it prevent development and perpetuate poverty in developing countries. An effective marketing and communication program about sustainable tourism is, however, found to be essential for economic success.

On the basis of the idea that an understanding of tourists’ perceptions and preferences will enable destination managers to design actions that are coherent with potential visitors’ expectations, this study aims to analyze the destination image perceived by visitors of Andalusia and its provinces over the past decade. A slightly modified Bray–Curtis dissimilarity index is calculated in order to synthesize in a single value the evolution of these destinations’ image during that period. The values obtained enable the identification of those provinces whose image has the strongest influence on the overall destination image of Andalusia. An examination is then made of which of the four major competitiveness components proposed by the Calgary Model explain the better or poorer quality of those destination images. Electre II methods are also applied to obtain a ranking of the provinces according to their level of attractiveness, as perceived by tourists.

Sustainable tourism management is becoming an increasingly important factor in the image of tourist destinations. Therefore, it is appropriate to consider the possibility of charging a premium price on certain tourism products or services in exchange for making them more sustainable. Generally, eco-friendly management of cultural heritage sites, and particularly World Heritage sites, along with protected natural areas, is essential for the image enhancement of tourist destinations. In line with these considerations, this paper aims to quantify the willingness to pay (WTP) an extra amount in order for certain tourism products and services to become more sustainable in a World Heritage city such as Caceres, Spain. By using the contingent valuation method, the average price increase that tourists visiting the city would be willing to pay for a double room in a hotel, a restaurant, entrance to a museum, or a taxi ride, all of which would become more sustainable services, has been estimated. In addition to the aggregate analysis, diverse average-comparison statistical techniques have been used in order to determine the possible influence of sociodemographic factors on the WTP for more sustainable products and services. Specifically, factors including the effect resulting from a tourist’s place of origin, gender, the year when the survey was conducted (through t-tests), and the effect of age and educational levels (through ANOVA tests) on the WTP for sustainability, have been analyzed. When considering all of the sociodemographic factors involved, notable statistical differences have been found. This implies that when a hypothetical increase in tourism prices for the purpose of financing public or private sustainability actions is considered, different segments of the tourism market should be taken into account, since it would not be appropriate to apply the same policy of price increases to all tourists equally.
