In this paper we generalize the concept of efficiency in multi-criteria problems from being the property of a point to that of a set of points. This generalization permits a variety of solution concepts to these problems. The uniqueness of solution distinguishes this approach from the usual concept of efficiency. 相似文献

The aim of this paper is to explore the effectiveness of asymmetric regulation, which allows a new mobile network operator to set higher termination rates than the incumbent operator. We assume that there are two market segments: one in which operators compete on equal terms, with a new technology, and the other in which the entrant is at a disadvantage since the technology it offers is inferior to the incumbent??s. Results show that asymmetric regulation can create favorable conditions that allow the entrant to strengthen its market positioning, and enhance consumer net utilities and social welfare. This highlights the importance of the degree of network asymmetry and the ways in which consumers are split between the two market segments. Lastly, we show that asymmetric regulation can create greater investment incentives for the entrant which could effectively enhance social welfare. These findings can provide useful insights for regulatory policy. 相似文献

How Can We Better Understand Current and Future Workforce Values in the Global Business Environment?
Malika Richards Carolyn P. Egri David A. Ralston Irina Naoumova Tania Casado Florian v. Wangenheim Vu Thanh Hung Andre A. Pekerti Sylvia Schroll‐Machl 《Thunderbird国际商业评论》2012,54(5):609-623
Our study tested the predictive power of socioeconomic development theory and age differences theory to explain work values across cultures and across age groups. We compared the values orientations of future managers, business students under the age of 25, with those of current managers and professionals, who we split into three decade groups (30 to 39, 40 to 49, and 50 to 59). Our respondents (n = 1,518) come from six diverse societies: Brazil, Germany, Indonesia, Russia, the United States, and Vietnam. Our findings indicate that both theories contribute to our understanding of work values and behaviors. One implication is that while socioeconomic development theory makes an important contribution, it is clearly not sufficient by itself to explain work values/behavior differences in the global context. The study findings and the discussion of them will hopefully provide multinational managers with a clearer assessment of current and future workforce values/behavior. © 2012 Wiley Periodicals, Inc. 相似文献

Although smuggled cigarettes have been a prevalent problem and a severe challenge to public health and welfare around the world, little is known about the behavior associated with smoking smuggled cigarettes and the issue is difficult to study due to data limitations. By means of a population‐based tobacco survey conducted in Taiwan, the present paper applies a latent class model to identify potential smokers who are either currently or will at some point in the future be consuming smuggled cigarettes. This methodology, in contrast to the traditional discrete models, allows potential smokers who are more inclined to smoke smuggled cigarettes to be endogenously classified. The empirical results indicate that socio‐demographic factors do increase the inclination to smoke smuggled cigarettes after unobserved heterogeneity has been accounted for. 相似文献

This study assesses tourist satisfaction and its links with service quality using a hierarchical model that combines four primary determinants and eight corresponding sub‐dimensions. A sample of 616 tourists departing from Kinmen Airport was surveyed with a structured questionnaire after they had just visited Kinmen National Park. A series of analyses was performed to explore tourist satisfaction with the four main service quality attributes as well as their willingness of repeat visits and recommendation. As a result, it was consistently found that service quality has positive significant relationship with tourist satisfaction. It is thus suggested that national park managers have to satisfy tourists with a high level of service quality, based on the concept that service quality may have a significant influence on long‐term behavioural intentions through high levels of customer satisfaction.

In this paper, we consider that the working environment has certain states, and in every state, the parameters of quality
characteristics are different. Thus, if we set the characteristics parameters in a specified state, these parameters will
change to another state. To describe this situation, we use a mixture of normal distributions, which comprise a flexible and
powerful statistical-based modeling tool in practice. Under the step loss function and the piecewise linear loss function,
we select the optimal means for the proposed manufacturing process. 相似文献

Asset selection and timing decisions are major investment concerns. To resolve these issues simultaneously, a new class of rainbow trend options is proposed. The diversification effect of rainbow options can reduce the importance of asset selection decisions and trend options can mitigate unfavorable effects on market entry and exit decisions. We consider a general framework to facilitate the derivation of analytic pricing formulas for simple, pure, and Asian rainbow trend options using the martingale pricing method. The properties of these options and their Greeks are analyzed. We also investigate the performance of the dynamic delta hedging strategy for issuers of rainbow trend options. Last, this paper explores the applications of rainbow trend options for hedging price risks, designing executive stock options, modifying countercyclical capital buffer proposed by Basel Committee, and acting as control variates of the Monte Carlo simulation. 相似文献

This study employs the fractional multinomial logit setting proposed by Papke and Wooldridge (1996) to examine factors driving the choice among nonbank private (144A) debt, bank loans and public debt made by 988 nonfinancial firms during 1993–2007. We document that the majority of firm-level factors have persistent effects on corporate outstanding debt mix across economic conditions. We also highlight the importance of macroeconomic variables on firms’ borrowing decisions as predicted by Diamond (1991). Finally, we document a substitution effect among debt financing sources due to credit rating downgrades, which is inconsistent with Rauh and Sufi (2010). 相似文献

This paper examines the determinants of automatic teller machine (ATM), a kind of information technology (IT), in the Taiwanese banking industry. The lessons learned from Taiwan's banking industry can be applied to China's banking industry to facilitate the understanding of the IT adoption strategies of Chinese financial institutions. Factors that are expected to have impact on IT investment in general and on ATM investment in particular are identified from three perspectives, namely operating scale perspective, deposit service perspective, and operating cost perspective. The results of this study indicate that operating scale, banking deposit service and operating cost are all significant determinants of ATM investment in the Taiwan banking industry. The results are useful for those banks and financial institutions outside of China in deciding their ATM investment strategies in China when trying to enter and penetrate the Chinese banking market. 相似文献
