The role of tourism is of vital economic importance, particularly for small countries with a privileged geographical location and favourable weather conditions. This paper examines the importance of tourism as a conditioning factor for higher regional growth in Portugal by employing the conditional convergence hypothesis of Barro and Sala-i-Martin, associated with the endogenous growth theory. The panel data estimation approach provides evidence of the positive impact of tourism (through the accommodation capacity) on the growth in per-capita income among the Portuguese regions, increasing the rate of convergence. Therefore, tourism can be considered as an alternative source for stimulating higher regional growth in Portugal, if the supply characteristics of this sector are improved. 相似文献

Many corporations are retraining midcareer managers in order to combat employee obsolescence and boost corporate competitiveness. The receptivity of midcareer managers to retraining is mixed. Those managers who believe they can master new work-related learning (in the terms of this study, those who have positive self-efficacy in learning beliefs) are most amenable to retraining. The objective of the present study was to determine the antecedents of positive self-efficacy beliefs for midcareer managers facing retraining. We discovered that managers' advancement potential and the relevance of their previous training had a profound impact on their self-efficacy beliefs. These findings have important practical implications. The seeds of receptivity to retraining are planted throughout managers' careers. Hence, retraining should not be viewed on a program-by-program basis, but rather should be understood in the broader context of corporate life and individual career history. To prepare for the inevitable corporate evolution and change demanded in a dynamic business environment, senior executives and human resource managers should be proactive in creating those conditions that facilitate the development of positive self-efficacy in learning beliefs. 相似文献

Collaborative, team-based research is now the most significant mode of activity in the global scientific community. Anecdotal and statistical evidence shows moreover that collaboration in scientific research is increasingly global in nature. That is, the groups of researchers who are involved in scientific progress often span one or more nations in origin, location and/or sponsorship. Another significant trend in recent cases of scientific collaboration is the increase in cross-sectoral cooperation, where researchers in a group are employed by government, private industry, and/or academic and other non-profit institutions.
In this paper, we review the scale, scope and intensity of cross-national, cross-sectoral research collaboration through the analysis of historical data on co-authorship of scientific publications. The first part of the paper reviews existing literature on the analysis of co-authorship data, and discusses the limitations of this form of analysis and typical strategies to mitigate those limitations. The second part of the paper describes a preliminary study of cross-national, cross-sectoral scientific collaborations covering the years 1988 through 1997, where we examined the scale (volume of co-authored papers), intensity (co-authored papers versus other kinds of co-authorship), and scope (patterns in co-authorship) for cross-national, cross-sectoral collaborations. The conclusion of the paper discusses significant trends and patterns derived from this study, and their implications for further research into these types of collaborations. 相似文献

This paper develops a model of North-South trade with multinational firms and economic growth in order to analyze formally the effects of stronger intellectual property rights (IPR) protection in developing countries. In the model, Northern firms invent new higher-quality products, multinational firms transfer manufacturing operations to the South and the Southern firms imitate products produced by multinational firms. It is shown that stronger IPR protection in the South (i.e., the adoption and implementation of the TRIPs agreement) leads to a permanent increase in the rate of technology transfer to the South within multinational firms, a permanent increase in R&D employment by Southern affiliates of Northern multinationals, a permanent decrease in the North-South wage gap, and a temporary increase in the Northern innovation rate. 相似文献

This paper analyzes the main characteristics of travel behavior by the Arab minority community in Israel and discusses two issues related to household travel surveys: data collection among minorities and under-reporting of mid-day trips.Household travel surveys are generally designed and conducted for the majority population and, therefore, lack a proper accounting of minorities and miss many of their less-frequent trips. An alternative approach to conducting household surveys is presented, with the aim of improving data quality for transportation planning. The survey was designed for and conducted in three Arab towns in Israel. The main improvement of the survey involves better interaction between interviewer and interviewee, which should materialize into a relaxed environment that allows for obtaining detailed, reliable results within a reasonable amount of time.The results of the survey employing the alternative approach were compared to a sub-sample of the same towns taken from a regional survey conducted by the regional planning agency at the same time. The paper presents simple statistics on the main variables for each survey. Significant differences are found in the two data sets, mostly regarding the frequency of less frequent, non-home-based trips. A plausible explanation for these differences relates to the more detailed and improved data collected in the new survey. 相似文献

Consumers face considerable frustration when purchasing structurally and/or semantically complex high-involvement products online. Reliance on computer-mediated communications for their information needs may result in functional and emotional frustration from information overload and lack of personal trust. This paper proposes a responsive real-time information system as a proxy for a perceptive sales representative who assesses customer needs based on information exchanges and then offers appropriate responses. By tracking and analyzing a consumer's online activity, vendors can offer information relevant to the consumer's real-time needs, facilitating their purchase process. In essence, this is a real-time value co-creation process based on the consumer offering cues to vendors through their key strokes and mouse click activity. This allows for differentiated information offerings for inexperienced and more experienced consumers, creating value by dynamic information serving. Where appropriate value is created, consumers will experience less frustration and continue online, rather than possibly moving offline or to alternative vendors. In examining the bases of consumer information needs in complex purchases, this paper identifies the data required to enable a responsive dialog between vendors and consumers. 相似文献

We study the asymptotic behavior of distribution densities arising in stock price models with stochastic volatility. The main objects of our interest in the present paper are the density of time averages of a geometric Brownian motion and the density of the stock price process in the Hull–White model. We find explicit formulas for leading terms in asymptotic expansions of these densities and give error estimates. As an application of our results, sharp asymptotic formulas for the price of an Asian option are obtained. 相似文献

This article presents evidence that the European Monetary System (EMS) bands for the Italian lira and the pound sterling were not credible for most of the period 1990–1992, and especially during the week prior to their withdrawal from the EMS system. Using a simple test, developed by Svensson, domestic interest rates for both Italy and the United Kingdom have been found to be mostly outside the rate-of-return bands implied by the official arrangements of the EMS target zone system. Furthermore, comparing implied forward rates for various maturities with the official EMS bands of both currencies, we again found that the followed monetary policies in both countries were not in general consistent with those needed to maintain an orderly functioning of the (EMS) system. The Svensson test can further be used as an indicator of potential speculative attacks on an EMS currency, and, in turn, as a signal of an emerging need to adjust the corresponding country's monetary policy. 相似文献

Abstract We consider two models in which the logarithm of the price of an asset is a shifted compound Poisson process. Explicit results are obtained for prices and optimal exercise strategies of certain perpetual American options on the asset, in particular for the perpetual put option. In the first model in which the jumps of the asset price are upwards, the results are obtained by the martingale approach and the smooth junction condition. In the second model in which the jumps are downwards, we show that the value of the strategy corresponding to a constant option-exercise boundary satisfies a certain renewal equation. Then the optimal exercise strategy is obtained from the continuous junction condition. Furthermore, the same model can be used to price certain reset options. Finally, we show how the classical model of geometric Brownian motion can be obtained as a limit and also how it can be integrated in the two models. 相似文献
