Fatou property,representations, and extensions of law-invariant risk measures on general Orlicz spaces

We provide a variety of results for quasiconvex, law-invariant functionals defined on a general Orlicz space, which extend well-known results from the setting of bounded random variables. First, we show that Delbaen’s representation of convex functionals with the Fatou property, which fails in a general Orlicz space, can always be achieved under the assumption of law-invariance. Second, we identify the class of Orlicz spaces where the characterization of the Fatou property in terms of norm-lower semicontinuity by Jouini, Schachermayer and Touzi continues to hold. Third, we extend Kusuoka’s representation to a general Orlicz space. Finally, we prove a version of the extension result by Filipovi? and Svindland by replacing norm-lower semicontinuity with the (generally non-equivalent) Fatou property. Our results have natural applications to the theory of risk measures.     

AN ANALYSIS OF THE MOST INFLUENTIAL ARTICLES PUBLISHED IN TOURISM JOURNALS FROM 2000 TO 2007: A GOOGLE SCHOLAR APPROACH

This research note reports a study that analyzed the 100 most influential articles, which is operationalized as the most cited publications published in tourism journals from 2000 to 2007. A Google Scholar‐based software system was developed in Java to retrieve the citation information. The empirical findings show that 10.16% of the citations were from Institute for Scientific Information‐listed (ISI) journals, and that 71.64% of them were from neither ISI nor tourism journals. The most popular topics covered by these articles were psychology and tourist behavior, followed by destination image and marketing. This article contributes to the literature by providing an alternative means of assessing the impact of research into tourism.     

Corporate social responsibility,firm reputation,and firm performance: The role of ethical leadership

This study investigated the antecedents and outcomes of corporate social responsibility (CSR) and the moderating effects of ethical leadership. We collected two-wave, temporally lagged data from two sources (general and vice-general managers) in 199 tourism firms (hotels and travel agencies) in southeast China. We have two major findings. First, ethical leadership moderated its own indirect effect on firm reputation via CSR. It had an indirect and positive effect on firm reputation through CSR when ethical leadership was strong but not when it was weak. Second, ethical leadership also moderated the indirect effect of CSR on firm performance via firm reputation. There was an indirect and positive effect of CSR when ethical leadership was strong but not when ethical leadership was weak. This study highlights the role of ethical leadership in linking the antecedents and outcomes of CSR, and provides support for the stakeholder theory.     

Learning goal orientation and creative performance: The differential mediating roles of challenge and enjoyment intrinsic motivations

We develop a theoretical model to account for the effect of learning goal orientation on creative performance by distinguishing two dimensions of intrinsic motivation as mediators. Challenge intrinsic motivation is concerned with the interest in and excitement of solving problems and tackling complex tasks, whereas enjoyment intrinsic motivation is concerned with the enjoyment of task activities for self-expression and self-entertainment. Results from a sample of 189 Chinese employees support this model and show that learning goal orientation had significant positive relationships with both dimensions of intrinsic motivation, but only challenge intrinsic motivation was significantly related to creative performance and mediated the positive relationship between learning goal orientation and creative performance. As predicted, intellectual stimulation, a dimension of transformational leadership, showed a moderating effect, such that learning goal orientation was less strongly related to challenge intrinsic motivation when intellectual stimulation was high. In addition, a moderated mediation effect was found, such that the mediating effect of challenge intrinsic motivation for the relationship between learning goal orientation and creative performance was weaker when intellectual stimulation was high. No such moderation effect was found for enjoyment intrinsic motivation, providing further support for the differential roles of these two dimensions of intrinsic motivation.     

Corporate governance and firm value during a financial crisis

The main purpose of this paper is to evaluate the effects of management ownership and other corporate governance variables on Hong Kong firms’ stock performance following the onset of the Asian Financial Crisis (1997–98). Our results show that Hong Kong firms with a more concentrated management (executive board) ownership displayed better capital market performance during the 13-month period of the Crisis. We also find that firms with more equity ownership by non-executive directors, and in which the positions of CEO and board chairperson were occupied by the same individual experienced a smaller stock price decline. Our findings are consistent with the notion that there is a greater alignment of insiders with outside owners, rather than the expropriation by insiders who have the opportunity to divert value, for firms with higher levels of management ownership during an unexpected capital market crisis.     

Counterparty Risk for Credit Default Swaps: Markov Chain Interacting Intensities Model with Stochastic Intensity

We analyze the counterparty risk for credit default swaps using the Markov chain model of portfolio credit risk of multiple obligors with interacting default intensity processes. The default correlation between the protection seller and underlying entity is modeled by an increment in default intensity upon the occurrence of an external shock event. The arrival of the shock event is a Cox process whose stochastic intensity is assumed to follow an affine diffusion process with jumps. We examine how the correlated default risks between the protection seller and the underlying entity may affect the credit default premium in a credit default swap.     

Productivity of Singapore's Manufacturing Sector: An Industry Level Non-Parametric Study

This paper seeks to measure and to explain the productivity of Singapore's manufacturing sector using industry level data. It utilises a non-parametric approach consisting of a set of production distance functions, each of which is obtained by solving a linear programming problem. From a time-series of 1983 to 1993, across thirty industries, we obtain three indices: a Malmquist total factor productivity (TFP) index, an efficiency change index, and a technological change index. The resulting TFP growth stands at 4.6% per annum, considerably greater than previous estimates using aggregate country level data. Three-stage least squares are then applied to the pooled data. Foreign ownership and labour quality are found to have important impact on TFP growth.     

Assessment for Learning: Using Solo Taxonomy to Measure Design Performance of Design & Technology Students

One objective of Design &; Technology (D&;T) is to enable students to be inventive in designing practical solutions to problems. D&;T is viewed as being successful when students can demonstrate the ability to recognize problems, undertake inquiries by themselves, and contribute ideas accordingly. This article will discuss a study which investigated an alternative approach to assessing students’ design performances. In the study, a new item format was designed and a new criterion framework of assessment based on Biggs’ SOLO Taxonomy was developed. The evidence from this study indicates strong face validity for the new approach which maps closely to the goals and purposes of learning D&;T.     

Issuer-oriented underpricing costs in initial public offers: Evidence from Hong Kong

This paper estimates the underpricing cost associated with new shares issued and sold when firms go public in a traditional British-style IPO market in contrast to prior work which focussed on the underpricing cost to pre-IPO investors. Secondly, the estimates account for interest income on application funds received by issuing firms. Using data from the Hong Kong IPO market, the results show that the issuer underpricing cost of new share issues is on average only 14% of headline underpricing. When interest on application funds is taken into account, net issuer underpricing cost reduces to just around 7% of headline underpricing. This finding provides a compelling explanation of why issuing companies may not be concerned about underpricing in traditional British-style IPO markets. Thirdly, we also find that pre-IPO investors take steps to minimise wealth transfer to new investors either by selling a very small proportion or none of their pre-IPO shares. These findings suggest that explanations of IPO underpricing to the various parties involved in the process should, in part, be sought in the institutional structures and investment banking practices of the relevant primary capital market.     

Profitability of the CRISMA System: From World Indices to the Hong Kong Stock Market

Many studies show that the use of technical analysis can generate excess returns. We test the “CRISMA” technical trading rule introduced by [Pruitt and White J. Portfolio Managt. Spring, 1988, 55–58] on global equity indices and common stocks in Hong Kong. Out study shows that no excess returns could be found in indices except those in Asia. This validates the claims that the Asian stock markets are not as efficient as other stock markets and hence can be exploited by technical analysis. How does CRISMA perform on common stocks in Hong Kong? Generally speaking, CRISMA does not fair better than the buy and hold strategy. Further analysis reveals excess returns for stocks with very large turnover. This is consistent with other recent research on CRISMA conducted on US and UK stock markets. We also amend part of the original CRISMA rules to yield better performance: shrinking the moving average window sizes can increase both the number of trade signals and the excess returns. Therefore CRISMA can be made to work with some judicious choice of parameters, depending on the turnover.
