Aging, Asset Markets, and Asset Returns: A View From Europe to Asia

The extent of the demographic changes is dramatic especially in some Asian and European countries. This paper investigates the effect of aging on global asset markets and asset returns, focusing on markets for productive capital, and especially on interactions between European and Asian economic development. Aging has complex effects on the markets for real capital. If elderly people save less than younger people, interest rates will increase. At the same time, however, the younger generation becomes smaller, which reduces the demand for new investment. The equilibrium effect is thus uncertain. Our multicountry computational equilibrium model delivers a subtle picture: there will be some decline in the return from productive capital, but it is relatively small. We find noticeable interaction effects between labor market and pension reforms in Europe on the one hand, and the demographic and economic developments in Asia, especially India and China, on the other hand.

Towards a geography of tourism

This paper traces the development of geographical interest in tourism during the past half century and examines the range and scope of the geography of tourism. The available literature is reviewed and suggestions are made regarding possible research aveneus and theoretical developments. Six major areas of interest are identified: spatial aspects of supply, spatial aspects of demand, the geography of resorts, patterns of movements and flows, the impact of tourism, and models of tourist space. Through an emphasis on spatial interaction an attempt is made to provide some cohesion and synthesis for this body of knowledge which constitutes the basis of the geography of tourism.     

Preferences and Willingness to Pay for Green Hotel Attributes in Tourist Choice Behavior: The Case of Taiwan

Although many companies in the hotel industry aim to pursue more sustainable and socially responsible practices, the present literature shows mixed results with regard to tourist reactions to such moves, especially for the service quality perception impacted by implemented green practices and the willingness to pay more for such actions. Unlike previous research examining tourists’ preferences for separate green hotel attributes, this study identifies the determinants of tourists’ choice of green hotel attributes. Additionally, the study measures the willingness to pay (WTP) for such services, in the context of the Taiwanese market, using the stated preference of combined green hotel attribute scenarios. A multinomial logit (MNL) model is employed to estimate the relative influence of behavioral and facility attributes on choice behavior. Furthermore, the study examines determinants influencing respondents’ choice of green hotel attributes. A latent variable class model (LVCM) approach is applied in the estimation of the unobserved heterogeneity, and a total of 390 valid respondents were used in the analysis. The empirical MNL results indicate that while tourists prefer luxury rooms and the provision of personal toiletries, they are also willing to accept reduced service quality. Additionally, sex, income, and age have significant influences on tourist choice behavior. The results of the LVCM model demonstrate that respondents with high levels of the green consumption trait are more likely to choose hotels that have a greater number of environmentally friendly attributes. The implicit amount that tourists are willing to pay for room quality is around US$13, for the provision of personal toiletries is about US$22, and for service quality is US$12, but they also require a discount of approximately US$11 in order to accept the common practices of green hotels. This study is useful in providing the hotel industry and government with quantitative information that can be used to develop and implement better green hotel policies.     

Restaurant's decision to purchase local foods: Influence of value chain activities

In this paper we investigate how restaurant managements’ attitudes and behaviors influence decisions to purchase local foods as inputs to their products. An enhanced investigation of chefs’ and managers’ decision-making criteria could improve understanding of local food systems linkages with the restaurant industry. We apply a value chain framework to investigate activities that influence restaurants’ decision to purchase local foods. Results indicate that attitudes and behaviors associated with sourcing and product characteristics play an important role in local food purchase decisions in the restaurant value chain. Order processing time and uniqueness of products are the most significant reasons in restaurant managements’ decisions to purchase local foods. The implications of these findings for restaurants and producers are discussed. Our study contributes to the literature by expanding upon the criteria used by restaurants to make local food purchasing decisions.
