Some results on residual entropy function

Ebrahimi and Pellerey (1995) and Ebrahimi (1996) proposed the Shannon residual entropy function as a useful dynamic measure of uncertainty. They studied the characterization problem from the residual entropy. They also used this function to define a stochastic order and two classes of distributions, DURL and IURL. In this paper, we obtain some new results on this function and we correct some mistakes in the preceding literature.Supported by Ministerio de Ciencia y Tecnologia under grant BFM2000-0362Acknowledgements.

Carrying capacity assessment for tourist destinations. Methodology for the creation of synthetic indicators applied in a coastal area

The growth and expansion of tourism is a complex phenomenon and its study requires multiple disciplines. When related to sustainability, the growth limits and carrying capacity of destinations must also be considered. The objective of this article is to develop a methodology to assess the growth limits of tourist destinations, and this method is then applied to the management and planning of an open tourist resort. The limits to growth are established using a mathematical formulation (i.e., multicriteria analyses, based on the reference point methodology) based on synthetic indicators applied to two scenarios: weak and strong sustainability. There are two developments in this type of research. The first is that the application of this method is neither restricted to a natural protected area, which has its own rules and management, nor to an island possessing geographically controlled entry and exit points. Rather, this study focuses on an open coastal area with an economy based on mass tourism. Second, this new way of assessing growth limits uses a flexible formula – adaptable to other coastal areas, e.g., rural, natural, and urban – depending on the impacts generated by the tourism and the objectives specified by destination managers.     

PROFILE OF A WINE TOURIST AND THE CORRESPONDENCE BETWEEN DESTINATION AND PREFERRED WINE: A STUDY IN ARAGON,SPAIN

Most of the existing characteristics of wine tourists have been based on the point of view of wineries or have been based on the tourists who have visited wineries. It is therefore necessary to establish a more general profile of wine tourists. In conjunction with this, a more in‐depth look must be taken at the motivations for visiting a destination. These motivations can include the production area of a preferred wine. The correspondence between the production area of a preferred wine and the destination selected by a tourist has been taken as a given in the research performed to date, but it has not been studied in depth. The results obtained show that the profile of a wine tourist can be divided into two groups, thereby considering the variables of gender, income, age, belonging to a wine club, wine consumption habits, and involvement in activities related to wine. Moreover, in the analyzed case there is positive correspondence between the place of origin of a preferred wine and the destination selected when participating in wine tourism.     

Assessing gender differences in ‘quick response’ code loyalty promotion acceptance

This study sheds light on quick response (QR) code loyalty promotion in terms of gender. Based on self-construal and gender scheme theories, we posit that the level of both involvement and social anxiety plays a crucial role in the gender effects of loyalty formation for promoted services. A scenario-based study in Japan with 667 consumers is constructed and examines two types of services: bank and supermarket. The findings suggest that, for high involvement (bank), compared with women, males act as competitive gamers who assume greater risk and seek attractive rewards with which to beat corporations, even under high social anxiety conditions. This finding seems consistent with independent self-construal among males. However, there is no significant difference for low involvement (supermarket). The implications are discussed and limitations recognized.     

Plant level evidence on product mix changes in Chilean manufacturing

This article analyzes changes in the product mix by Chilean manufacturing plants in the period 1996–2003. Three quarters of the surviving plants changed the set of products produced and more than three quarters of the exporting plants changed the mix of products they exported during the sample period. Plants that changed their product mix contributed 85% of the aggregate growth in real sales of surviving plants between 1996 and 2003. Finally, and in contrast to the US evidence, there is a negative correlation between revenue per product and the number of products. Apart from this, new evidence consistent with recent models of multi-product heterogeneous firms and trade is provided.     

Generalized cumulative residual entropy and record values

The Shannon entropy of a random variable has become a very useful tool in Probability Theory. In this paper we extend the concept of cumulative residual entropy introduced by Rao et al. (in IEEE Trans Inf Theory 50:1220–1228, 2004). The new concept called generalized cumulative residual entropy (GCRE) is related with the record values of a sequence of i.i.d. random variables and with the relevation transform. We also consider a dynamic GCRE obtained using the residual lifetime. For these concepts we obtain some characterization results, stochastic ordering and aging classes properties and some relationships with other entropy concepts.     

Asymptotic behavior of the hazard rate in systems based on sequential order statistics

The limiting behavior of the hazard rate of coherent systems based on sequential order statistics is examined. Related results for the survival function of the system lifetime are also considered. For deriving the results, properties of limits involving a relevation transform are studied in detail. Then, limits of characteristics in sequential \(k\) -out-of- \(n\) systems and general coherent systems with failure-dependent components are obtained. Applications to the comparison of different systems based on their long run behavior and to limits of coefficients in a signature-based representation of the residual system lifetime are given.     

Do ICT Influence Economic Growth and Human Development in European Union Countries?

This study analyzes the influence of the introduction of Information and Communication Technologies (ICT) on economic growth and human development in the countries that make up the European Union 27. The remarkable interest that the European Commission has shown in the Information Society (IS) and the introduction of ICT inspired us to analyze to what extent ICT had established themselves in these countries. More specifically, countries are grouped in accordance with some of the main IS indicators published by Eurostat to ascertain whether or not there are different groups of countries with different levels of development and where ICT have been implemented to different degrees. We determine whether they have achieved different levels of economic and human development. This enables us to confirm (or reject) the main theories that suggest ICT have a strong influence on economic and human development. Results show the existence of four clearly distinct groups of countries which register significant differences.     

International evidence on alternative models of the term structure of volatilities

The term structure of instantaneous volatilities (TSV) of forward rates for different monetary areas (euro, U.S. dollar and British pound) is examined using daily data from at‐the‐money cap markets. During the sample period (two and a half years), the TSV experienced severe changes both in level and shape. Two new functional forms of the instantaneous volatility of forward rates are proposed and tested within the LIBOR Market Model framework. Two other alternatives are calibrated and used as benchmarks to test the accuracy of the new models. The two new models provide more flexibility to adequately calibrate the observed cap prices, although this improved accuracy in replicating cap prices produces some instability in parameter estimates. © 2009 Wiley Periodicals, Inc.

Economic Sentiment and Yield Spreads in Europe

According to Harvey (1988) , the forecasting ability of the term spread on economic growth is due to the fact that interest rates reflect investors' expectations about the future economic situation when deciding their plans for consumption and investment. Past literature has used ex post data on output or consumption growth as proxies for their expected value. In this paper, we employ a direct measure of economic agents' expectations, the Economic Sentiment Indicator elaborated by the European Commission, to test this hypothesis. Our results indicate that a linear combination of European yield spreads explains a surprising 93.7\% of the variability of the Economic Sentiment Indicator. This ability of yield spreads to capture economic agent expectations may be the actual reason for the predictive power of yield spreads about future business cycle.
