Market illiquidity and bounds on European option prices

The paper analyses the impact of illiquidity of a stock paying no dividends on the pricing of European options written on that stock. In particular, it is shown how illiquidity generates price bounds on an option on this stock, even in the absence of other imperfections, such as transaction costs and trading constraints, or the assumption of stochastic volatility. Moreover, price bounds are shown to be asymmetric with respect to the option price under perfect liquidity. This fact explains, under some conditions, the appearance of a smile effect when the implied volatility is estimated from the mid-quote.     

Monetary policy for an open economy: an alternative framework with optimizing agents and sticky prices

The 'new open-economy macroeconomics' seeks to provide an improvedbias for monetary and exchange-rate policy through the constructionof open-economy models that feature rational expectations, optimizingagents, and slowly adjusting prices of goods. This paper promotesan alternative approach for constructing such models by treatingimports not as finished consumer goods but rather as raw-materialinputs to the home economy's productive process. This treatmentleads to a clean and simple theoretical structure that has someempirical attractions as well. A particular small-economy modelis calibrated and its properties exhibited, primarily by meansof impulse response functions. The preferred variant is shownto feature a pattern of correlations between exchange-rate changesand inflation that is more realistic than provided by a morestandard specification. Important recent events are interpretedin light of the alternative models.     

Role of Gender in Conflict Handling in the Context of Outsourcing Service Marketing

Do male and female outsourcing service marketers differ in their responses to conflict‐handling styles of outsourcers? The paper addresses this question by identifying relationship‐oriented typologies of conflict handling from extant literature and examining their effects on key relational outcomes in outsourcing relationship in A sia. Specifically, the paper considers how outsourcers’ conflict‐handling styles impact trust and commitment by male and female outsourcing service providers’ ( OSP s). Data were collected from male and female OSP s and analyzed using F actor and H ierarchical M ultiple R egression analyses. Findings show significant differences in the relationship between conflict‐handling styles and relational outcomes between male and female OSP s. Precisely, integrating conflict handling–trust relationship is significantly stronger for males than for females, whereas compromising conflict handling–trust relationship is significantly stronger for females than for males. Findings show no statistical differences in accommodating conflict handling–trust relationship between the groups. These findings lead to research and managerial implications that conclude the paper.     

Thirty years of research on tourism and hospitality management in China: A review and analysis of journal publications

The tourism industry in China has undergone rapid development since 1978 and is foreseen as being the world's largest tourism market by 2020. However, no comprehensive review of literature in this context has been completed, and international academics have little understanding of China tourism research. This paper aims to provide an overview of 119 articles selected from six leading English language academic journals published from 1978 to 2008. Content analysis points to the evolving trend in Asian universities in terms of journal contributions. Consumer behavior has gained popularity as a research topic, and will likely remain as a prevalent research theme in the near future. A tendency toward multiple-authorship, rather than single authorship, and more sophisticated methodological procedures has also been found. Future analysis may focus on including other forms of publications and Chinese language journals to capture the full picture of China tourism.     

Dimensions of Chinese culture values in relation to service provision in hospitality and tourism industry

Factor and reliability analyses were employed in this exploratory attempt to investigate and refine the structure and dimensions of Chinese cultural values (CCVs) in relation to service provision. Based on the results of factor analysis, CCVs could best be conceptualized as a five-component construct that influences the attitude or behavior of employees in providing service. These five factors were identified as follows: Integration 1 (attitude towards work); Integration 2 (attitude towards people); moral discipline; status and relationships; and moderation. The identification of these dimensions has two major implications to human resource development and service management practice in the hospitality and tourism industry. First, Chinese cultural values play a critical role in determining specific interventions, challenges and barriers in service organizational management. Second, given the profound influence of Chinese cultural values on service provision, international tourism and hotel managers, particularly in human resource development, should realize the importance of ensuring that Western management practices are adopted critically in Chinese organizations. Given the limited amount of research on this topic, the findings generated from this study are very important in guiding future research and providing insights into an area that deserves more academic attention.     

Improved approximations for the aggregate claims distribution of a life insurance portfolio

Abstract

In an earlier paper the author derived a recursion formula which permits the exact computation of the aggregrate claims distribution in the individual life model. This exact procedure requires of course more computing time than approximative methods such as Kornya's algorithm, which seemed to be the best compromise between accuracy and computational effort. In the present paper it is shown that, to save time, the exact formula can be used in an approximative way and that the corresponding error bound is smaller than the one of the Kornya-type approximations.     

Simple binomial processes as diffusion approximations in financial models

A binomial approximation to a diffusion is defined as 'computationallysimple' if the number of nodes grows at most linearly in thenumber of time intervals. It is shown how to construct computationallysimple binomial processes that converge weakly to commonly employeddiffusions in financial models. The convergence of the sequenceof bond and European option prices from these processes to thecorresponding values in the diffusion limit is also demonstrated.Numerical examples from the constant elasticity of variancestock price and the Cox, Ingersoll, and Ross (1985) discountbond price are provided.
