Pricing basket and Asian options under the jump‐diffusion process

This study derives approximate valuation formulas for basket options and Asian options under the jump‐diffusion process. To obtain an approximation for options prices under the jump‐diffusion process, we extend the Taylor expansion method developed by Ju N. ( 2002 ) under the diffusion process. We show that the Taylor expansion method, suggested in this study, provides better pricing performance as compared to log‐normal or four‐moment methods. The performance improvement using the Taylor expansion method increases as the time to maturity increases. In addition, our numerical analysis shows that jump effects become significant when the expected jump sizes take large negative values. © 2011 Wiley Periodicals, Inc.

“I won't leave you although you disappoint me”: The interplay between satisfaction,investment, and alternatives in determining consumer–brand relationship commitment

While commitment is among the key constructs of consumer–brand relationships, past research has regarded the impact of predictors of brand commitment as being linear and has ignored potential interactive effects among the different antecedents. Applying the investment model of interpersonal relationship, the present research examines the dynamic interplay among the key determinants of consumers' commitment to their relationship with brands (satisfaction, alternatives, and investment) and substantiates the roles of the antecedents in consumer–brand relationship contexts. Results of two studies demonstrate that greater consumer satisfaction and investment and less attractive alternatives lead to a higher level of consumers' commitment to their relationship with a brand. Most important, the results suggest that the perceived size of investment exerts a stronger impact on brand relationship commitment when satisfaction is low while making no significant difference in the commitment level when satisfaction is high. Conversely, the influence of alternative attractiveness on brand relationship commitment appeared to be largely monotonic. © 2010 Wiley Periodicals, Inc.     

Options‐based HRM,intellectual capital,and exploratory and exploitative learning in law firms' practice groups

The current study intends to uncover the strategic contribution of human resource management by introducing a unique construct of options‐based (vis‐à‐vis project‐based) HRM and examining its links to intellectual capital and exploratory and exploitative learning in the context of law firms' practice groups. Empirical results show that options‐based HRM is positively related to the practice group's explorative and exploitative learning. The intellectual capital mediates the relationships between options‐based HRM and the practice group's learning for exploration and exploitation. This study makes a valuable contribution to the HRM literature by establishing the mechanisms by which HRM enables organizational learning and extending the scope of HRM research to professional service firms. Our findings also provide valuable implications for the literature of organizational learning. © 2012 Wiley Periodicals, Inc.     

Analyst Forecasting Ability and the Stock Price Reaction to Forecast Revisions

We empirically identifysuperior analysts using their past forecasting track record fora specific firm's earnings and demonstrate that subsequent forecastannouncements by these superior analysts have a greater impacton security prices than do the forecasts of other analysts. Wefind that, in our sample, the price effects of this firm-specificforecasting ability do not spill over to other firms followedby the same analyst. We also demonstrate that an analyst's forecastingability with respect to the earnings of a certain firm is relativelymore important in the period immediately preceding an earningsannouncement by that firm.     

A three-level supply chain network design model with risk-pooling and lead times

This paper considers a single-sourcing network design problem for a three-level supply chain consisting of suppliers, distribution centers (DC’s) and retailers, where risk-pooling strategy and DC-to-supplier dependent lead times are considered. The objective is to determine the number and locations of suppliers and DC’s, the assignment of each location-fixed DC to a supplier and that of each retailer to a DC, which minimizes the system-wide location, transportation, and inventory costs. The problem is formulated as a nonlinear integer programming model, for which a two-phase heuristic solution algorithm is derived based on the Lagrangian relaxation approach. Numerical experiments show that the proposed heuristic is effective and also efficient.

Gender Wage Differentials and Occupational Segregation in Hong Kong, 1981–1996

This paper analyses gender wage differentials and the role of occupational segregation in Hong Kong. It is found that the female–male earnings ratio increased substantially from 0.710 in 1981 to 0.839 in 1996. A decomposition which takes into account occupational differences shows that the gender pay gap is mostly within occupations and most of the intra‐occupation wage gap is unexplained. The gender pay differential due to occupational differences is small; in fact, the overall occupational segregation favours females in Hong Kong.     

An Exploratory Study of the Otaku Adolescent Consumer

High accessibility to Internet technology and popularization of focus media has given rise to various emerging subcultures among the younger generation who constantly seek novelty. The otaku is such an adolescent subculture of avid collectors who have a special lifestyle and who are obsessed with anime products. This study explores this specific adolescent segment's traits and purchasing behavior patterns. A focus‐group interview was conducted with some adolescent otaku to allow them to express their opinions and purchasing behaviors. Then, a questionnaire was developed based on the interview's findings, and data from a survey of 105 respondents were collected. Exploratory factor analysis was applied to extract the otaku's trait factors, while confirmatory factor analysis and structural equation modeling were used for the verification of the scale and structural model, respectively. The results show that the adolescent otaku present an obsessive preference for visual perception. The main factor influencing the otaku's purchasing intentions in terms of animation, comics, and games (ACG) is their strong interest in and participation willingness toward ACG. Strategic marketing directions applied to this adolescent group should emphasize information visualization to entice their buying behavior.     

The tourist experience of domestic VFR travellers: the case of Hungary

Visiting friends and relatives (VFR) is the main driver of domestic travel in many countries. This study is one of the first to analyse VFR travel from a perspective of tourist experience. This study aims to investigate the complex dynamics behind VFR-related travel, especially in aspects of trip activities and tourist experience formation. Based on a survey (N?=?879) examining domestic VFR travellers’ trip activities in Hungary, the paper discusses the formation of a tourist experience in context of short-haul domestic VFR travel, especially the role of influencing factors. The results reveal differences between the segments with trip motivation of visiting friends (VF) and visiting relatives (VR) – the two main types of VFR tourists. It was found that independent variables such as VF, staying for longer and participating in leisure and tourism-type activities have a positive effect on tourist experience evolvement; however, factors such as VR, being rather passive during such a visit and focusing on social acts and bonding negatively affect the formulation of a tourist experience. The paper’s novelty and uniqueness lies in applying a new perspective of analysing and discussing VFR travel: the theoretical concept of tourist experience formation.
