Static hedging and pricing American knock-in put options

This paper extends the static hedging portfolio (SHP) approach of  and  to price and hedge American knock-in put options under the Black–Scholes model and the constant elasticity of variance (CEV) model. We use standard European calls (puts) to construct the SHPs for American up-and-in (down-and-in) puts. We also use theta-matching condition to improve the performance of the SHP approach. Numerical results indicate that the hedging effectiveness of a bi-monthly SHP is far less risky than that of a delta-hedging portfolio with daily rebalance. The numerical accuracy of the proposed method is comparable to the trinomial tree methods of  and . Furthermore, the recalculation time (the term is explained in Section 1) of the option prices is much easier and quicker than the tree method when the stock price and/or time to maturity are changed.     

Driving Goal-Directed and Experiential Online Shopping

Goal-directed and experiential online shopping are two general categories of consumer behavior on the Internet. Internet stores promoting online transactions may face challenges regarding how to satisfy distinct online shoppers. This study develops a dual-state of cognitive and affective reactions to online services and flow experiences to predict goal-directed and experiential online consumer behavior. This survey mailed 300 questionnaires to a random sample of volunteers with substantial online shopping experience. Of these, 150 samples were returned for data analysis. Empirical results from the survey indicate that the dual-state of online services is more appropriate for assessing goal-directed purchase intentions than for examining the willingness to purchase experientially. In contrast, the dual-state of flow experiences is better at assessing goal-directed purchase intentions and the willingness to purchase experientially. Finally, this study features implications for academics and practitioners.     

The determinate effects of competences and decision process factors on firms' internationalisation

This study introduces the current situation of Taiwan's financial industries and presents a literature review including competences, competitive advantage, and key factors under the process of the international investment decision, and internationalisation. The study takes a ‘triangulation’ approach that uses both qualitative and quantitative methods in the exploration of the internationalisation of Taiwan financial markets. Sampling targets of the research consist of managers from banks, security firms, and insurance firms in Taiwan. The findings highlight perceptions of factors such as resources, skill, market knowledge, and international investment experience of firms aiding the internationalisation of Taiwan financial industry. Further, this study reveals that firms' internationalisation relates positively to the firms performance.     

Performance effects of category assortment and stock allocation decisions for a cash-and-carry wholesaler

This study develops and tests a model of how category assortment, category stock level and within-category stock allocation decisions might affect category sales and stock turnover and reflect category-varying levels of sales heterogeneity and sales volatility. In doing so, it addresses recent calls to consider multiple dimensions of assortment planning. It uses the cash-and-carry wholesaling setting to isolate non-space-related assortment planning and performance variables otherwise difficult to treat in a conventional retailing (e.g. supermarket) context. It develops a structural equation model of how category sales volatility and heterogeneity, as antecedents, might influence both category assortments and stock allocations and thus, in turn, influence category performance.     

Capitalization of Costs and Expected Earnings Growth

Abstract

This paper offers a model that shows how the capitalization of costs affects contemporaneous earnings and the growth path of expected earnings. It makes three points. First, reported earnings under successful efforts are more price relevant than earnings under full costing or full expensing. Second, whether conditional or unconditional, conservatism always enhances the growth rate of expected earnings. Third, independent of capitalization policy, the long-run expected earnings growth rate converges either to the long-run expected free cash flow growth rate or to the depreciation rate. Therefore, while capitalization policy affects the price relevance of earnings and short-run expected earnings growth, it does not affect long-run expected earnings growth.     

Competence maps for the information service industry

The primary aim of this paper is to construct competence maps for the information service industry. Starting with a review of the literature related to the information service industry and the competence in this industry, this study defined a pool of competence items and developed a questionnaire for field survey. Based on the data collected from the information service companies in Taiwan, a series of factor analyses with item filtration was carried out. This resulted in a six-factor solution including Cognition, Management I (organizing, leading, and controlling), Management II (planning), Technology Infrastructure, Application Systems, and Clerical Processing as the competence sets. Then the factor-based scales were created to represent the derived competence sets, the pairwise correlations between these scales were calculated, and the competence maps were constructed accordingly. The results obtained may be helpful to the internal (e.g., training/education, deployment, or substitution) and the external (e.g., recruitment) developments of human resource in information service companies.     

Perceiving Airbnb as sharing economy: the issue of trust in using Airbnb

Airbnb is a growing business and has received much research attention. However, no research has specifically examined complaints against Airbnb. Understanding complaints serves not as a way to help improve services but provides an insight into guests’ perception of the Airbnb. I examined 664 reviews on sitejabber.com to study the common complaints and whether they are related to the perception that Airbnb is sharing economy. Using a grounded theory approach, I performed a content analysis of complaints. Besides customer service and technology challenges, one major complaint against Airbnb is their faded trust through their experiences.     

International diffusion of embodied and disembodied technology: A network analysis approach

This study proposes a quantitative method for investigating the structure of international technology diffusion. By using network analysis, this study defines the structural configuration of each country within the international diffusion network by measuring its degree, closeness, and betweenness centralities. In addition, this study distinguishes between embodied technology diffusion, measured by multilateral trade, and disembodied technology diffusion, measured by patent citations, in individual countries. This study empirically tests a sample data set of international technology diffusion taken from 48 countries. The empirical results show that the structural configuration of countries exhibits similar patterns in both embodied and disembodied diffusion networks. Significant global stratification patterns exist in the capability of national international technology exportation and brokerage advantages. Moreover, this study distinguishes four blocks of countries that play different roles in international technology diffusion: the leading countries provide a source of technological knowledge; an intermediate group diffuses the knowledge acquired from the source; a third group is in the process of initiating the export of technological knowledge; and a final group of countries absorbs technological knowledge without reciprocal exportation. Finally, this study identifies two types of catch-up strategies that newly industrialized or developing countries can use to move up the international technology stratification.     

Direct and Multiplicative Effects of Ethical Dispositions and Ethical Climates on Personal Justice Norms: A Virtue Ethics Perspective

From virtue ethics and interactionist perspectives, we hypothesized that personal justice norms (distributive and procedural justice norms) were shaped directly and multiplicatively by ethical dispositions (equity sensitivity and need for structure) and ethical climates (egoistic, benevolent, and principle climates). We collected multisource data from 123 companies in Hong Kong, with personal factors assessed by participants’ self-reports and contextual factors by aggregations of their peers. In general, LISREL analyses with latent product variables supported the direct and multiplicative relationships. Our findings could lay the groundwork for justice research from a morality perspective in future.     

Comparison of attitudes towards school lunch by elementary school children in Japan,Korea and Thailand

The attitudes of elementary school children towards school lunch among three Asian countries, namely Japan, Korea and Thailand, were compared. More school children in Japan felt that their teachers gave them advice during the school lunch programme. Japanese and Korean teachers advised their children to eat as much as possible of the lunch. Korean children may be a little more obedient with regard to heeding the advice. However, few teachers in Thailand gave the children advice over eating lunch, and the Thai children looked forward to and enjoyed the school lunch. The different responses between Thailand and other two countries may be attributed in part to the differences in the teachers' instruction in the programme. Elementary school teachers, especially in Thailand and Korea, have to take more classes in food and nutrition in universities or colleges, and positively take part in the school lunch programme.
