The limitation of monotonicity property of option prices: an empirical evidence

Many option pricing models are based on the assumption that the underlying asset price follows one-dimensional diffusion process. An alternative approach is to test the properties that should hold for all models based on a given stochastic process for the underlying asset. Following Pérignon (2006 Pérignon, C. 2006. Testing the monotonicity property of option prices. Journal of Derivatives, 14: 61–76. [Crossref] , [Google Scholar]), we test the empirical validity of the monotonicity property for option prices by collecting all transaction data from 1 July 2006 to 31 December 2006 for option contracts traded on the Taiwan Futures Exchange (TAIFEX). We find that sampled intraday option prices violate the monotonicity property between 29.97% and 57% of the time, and that call and put prices often increase, or decrease, together. We also find evidence to show that the frequent violations of the monotonicity property are to a large extent attributable to microstructure effects and that they arise from rational trading tactics.     

The effect of reducing risk and improving personal motivation on the adoption of knowledge repository system

The role of Knowledge Repository Systems (KRSs) is to provide the exchanging intermediaries of explicit knowledge between knowledge contributors and knowledge seekers to assist knowledge sharing of employees in the organization. However, there is still a lack of deep understanding of how to reduce perceived risk and improve personal motivation on the adoption of KRSs in previous research. The paper presents social-psychological-technical perspectives to integrate social factors of reduced perceived risk (trust and organizational support) into Motivation Model (MM) and develop a comprehensive framework for assessing and analyzing the interaction of technology with the social, psychological, and behavioral aspects in KRSs. The proposed framework is validated with 528 respondents from teaching hospitals located in Taiwan, which shows that social factors of reduced perceived risk, personal motivation factors, and technology quality factors are three key factors affecting the acceptance of the KRSs. In other words, technological, social, psychological aspects will affect simultaneously behavioral intention in KRSs. Moreover, the psychological aspects are important mediators among technological, social, and behavioral aspects. The findings may be used as theoretical base for future research and offer empirical foresight to managers of organizations in assessing and evaluating the performance of the KRSs.     

Modeling diffusion of multi-generational LCD TVs while considering generation-specific price effects and consumer behaviors

An effective diffusion model characterized by the technology-induced function diversification and cost reductions can be developed to reflect whether competition exists among multiple generations of technology and to interpret how price reductions stimulate consumption. New technology can enhance the production skill levels of LCD TV manufacturing, enabling successive generation of LCD TV to become larger-sized than the previous generation, reducing the overall cost in manufacturing process and resulting in the price reduction of LCD TVs. However, previous diffusive predictions of LCD TVs using conventional multi-generational models ignore the price effect on market potentials and generational substitutions, so a novel generation-specific multi-generational model for the first time incorporating heterogeneous price elasticity and consumer behaviors across various LCD TV sizes is constructed in this work. This study applies nonlinear least square method to simulate the parameters of our modified model and further compares the accuracy between our modified model and the existing models. Analytical results indicate that price reduction strongly correlates with LCD TV sales, implying that price reductions increase the market potential of each LCD TV generation. Our modified model performs superior to the conventional multi-generational model in terms of predicting future shipment orbits of 26-, 42-, and 46-in. LCD TVs.     

Duopoly locations and optimal zoning in a small open city

This paper analyzes a duopoly location model with an asymmetric zoning that prohibits firms from locating to a specific interval in a small open linear city. It is shown that the maximum differentiation principle presented in d'Aspremont et al. [Econometrica 47 (1979) 1145] is still valid under area zoning regulation. Moreover, a zoning regulation can be seen as a policy instrument to limit firms' excess profits, and a proper regulation may even reduce the distortion in total transportation costs, therefore enhancing social welfare. Specifically, the optimal zoning is about 29.5 percent of the city with no amenity effect. Finally, all the land rents raised by zoning are eventually confiscated by the absentee landowner.     

The relationship between institutional ownership and casino firm performance

This study examined the relationship between institutional ownership and firm performance in the casino industry from 1999–2003. Given the evidence of the endogeneity of institutional ownership in the casino industry, institutional ownership was found to be a significant and positive determinant of casino firm performance as measured by a proxy for Tobin's Q in a simultaneous equations system. This study reveals that investing institutionally in casino firms may help casino industry investors mitigate the agency problem caused by the separation of management from ownership. In addition, financial institutions tend to invest in larger casino firms with lower financial leverage.     

Analysis of career competency of food and beverage managers in international tourist hotels in Taiwan

The purpose of this study is to establish indicators of career competencies of food and beverage managers in international tourist hotels in Taiwan. Panel discussions and the Delphi technique were adopted. Two panel discussions were conducted with a total of 11 industry experts and seven academic experts. The framework of career competencies was established based on these experts’ opinions. Delphi questionnaires were sent to 23 experts 13 in the hospitality industry and ten academic experts to collect data. By using such questionnaire twice, the 23 panelists reached a stable consensus. The results indicate career competencies include two categories: (1) career planning and development, and (2) core employability. The data demonstrated that the core employability competency was slightly more important for an individual's career development than the career development and planning competency.     

Understanding the impact of culinary brand equity and destination familiarity on travel intentions

This paper explores determinants of brand equity and the role of destination familiarity for travel intentions in culinary tourism from the perspective of foreign tourists. This analysis advocates four elements for brand equity (brand loyalty, brand image, perceived quality and brand awareness) for culinary travel intentions in Taiwan. Building on extensive literature, this study developed and empirically tested a model of the relationship using survey data collected from 407 foreign tourists from ten regions. The results indicate that there is a direct positive relationship between brand equity and travel intentions in culinary tourism. Moreover, the study recognizes the moderating role of destination familiarity, which positively moderates the effect of brand loyalty and perceived quality on travel intentions.     

Earnings,institutional investors,tax avoidance,and firm value: Evidence from Taiwan

This study examines the valuation of earnings from China and Taiwan by foreign and domestic institutional investors across a sample of Taiwanese electronics firms. We further compare the valuation of firm earnings reported in tax havens and non-tax havens, and whether these firms have changed tax avoidance activities since 2004 when the Taiwanese government enacted stricter auditing of transfer pricing regulation.Our findings show that both operating income from the home country and investment income are positively associated with firm value. Operating income from China, however, is not significantly related to firm value when institutional ownership of the firm exceeds fifty percent. This result indicates that operating income is valued differently, depending on the location from which the income was generated. Non-operating income enhances firm value regardless of the revenue source. We also report that foreign institutional investors favor operating income from domestic and investment sources over earnings generated from non-domestic sources and other non-operating income. Furthermore, our results suggest that firms rearrange reported profits from subsidiaries located in tax havens to affiliates in other countries following the transfer pricing audit guide Taiwan implemented in 2004. Results also indicate firms may have been shifting profits to other low-tax-rate countries, or to countries which do not require firms to pay taxes, even if they are not doing business in that country.     

Monetary policy and stock returns: Financing constraints and asymmetries in bull and bear markets

We examine asymmetries in the impact of monetary policy surprises on stock returns between bull and bear markets in the period 1994 to 2005. We ask how these impacts respond to the relative ability of firms to obtain external finance. We find that the impact of a surprise monetary policy in a bear market is large, negative, and statistically significant, and this holds across size decile portfolios. The impact of a surprise policy action in a bear market for most industries is significantly greater than the impact of surprise monetary policy in a bull market. Controlling for the capacity for external finance, stock returns of firms in bear states respond more than firms in bull states. Capacity for external finance is more important in a bear market, as it partially mitigates the larger impact of monetary policy in a bear market.
