IPO anomalies and innovation capital

Innovation capital are typically expensed and/or unrecognized as assets under current generally accepted accounting principles. This results in accounting-related information asymmetry. This paper examines the association of innovation capital (as measured here by the proxies of R&D expenditures and granted patents) and initial public offerings (IPO) anomalies. These anomalies include initial IPO underpricing, duration of honeymoon (a distinct feature of the Taiwanese IPO environment), and long-term performance. The theoretical model underlying this research is a signaling model. The results indicate that more innovative firms are more likely to be underpriced, and have longer honeymoon periods than less innovative firms. Further, the more innovative firms have positive and growing long-term market-adjusted returns. This stands in contrast to the declining long-term stock performance of initial public offering firms that is evidenced in the literature. We conclude that pre-IPO research and development expenditures disclosed in the IPO prospectus, official monthly reports of newly developed patents released to the public, and the frequency of patent citations significantly signal both underpricing and future market performance of IPO firms in Taiwan.     

Valuation of vulnerable American options with correlated credit risk

This article evaluates vulnerable American options based on the two-point Geske and Johnson method. In accordance with the Martingale approach, we provide analytical pricing formulas for European and multi-exercisable options under risk-neutral measures. Employing Richardson’s extrapolation gets the values of vulnerable American options. To demonstrate the accuracy of our proposed method, we use numerical examples to compare the values of vulnerable American options from our proposed method with the benchmark values from the least-square Monte Carlo simulation method. We also perform sensitivity analyses for vulnerable American options and show how the prices of vulnerable American options vary with the correlation between the underlying assets and the option writer’s assets.      

The relationship between stock returns and volatility in international stock markets

This study examines the relationship between expected stock returns and volatility in the 12 largest international stock markets during January 1980 to December 2001. Consistent with most previous studies, we find a positive but insignificant relationship during the sample period for the majority of the markets based on parametric EGARCH-M models. However, using a flexible semiparametric specification of conditional variance, we find evidence of a significant negative relationship between expected returns and volatility in 6 out of the 12 markets. The results lend some support to the recent claim [Bekaert, G., Wu, G., 2000. Asymmetric volatility and risk in equity markets. Review of Financial Studies 13, 1–42; Whitelaw, R., 2000. Stock market risk and return: an empirical equilibrium approach. Review of Financial Studies 13, 521–547] that stock market returns are negatively correlated with stock market volatility.     

关于无形资产评估中折现率确定方法的探讨

折现率的预测和确定是无形资产评估中的难点问题之一。由于折现率是影响评估结果准确度的重要参数,所以在当前对高质量资产评估结果的需求日益迫切的背景下,有必要再度探讨无形资产折现率确定方法的相关问题。本文提出应根据引起无形资产评估的具体情况来选择合理的折现率确定方法;同时也提出了无形资产折现率确定方法运用和发展的几点建议:科学性和合理性相结合、静态分析与动态分析相结合、因素分析与模型分析相结合。     

Impact of sales force automation on technology-related stress, effort, and technology usage among salespeople

This study unveils factors affecting sales force automation (SFA) technology usage by salespeople. It differs from previous research by: (1) proposing a model that examines the consequences of task complexity on role perceptions and technology usage, and (2) understanding the negative repercussions of SFA technology on the user. The proposed model was tested using data from 150 salespeople employed by a national organization. The results suggest that integration of SFA technology induces adverse role perceptions in salespeople. However, controlling for extraneous variables, effort is significantly related to salespeople's usage of technology. Key managerial implications for theory and practice are discussed.     

"卡脖子"技术协作攻关的政府择优支持制度研究

"卡脖子"技术是一种"人有我无""受制于人"的共性技术,政府支持对其协作攻关必须以择优制度为保障.由于"卡脖子"技术是一种可对标的特殊共性技术,因而政府择优支持制度具备择优条件,可以有效防范支持制度的政府失灵.政府择优支持制度包含择优技术标准、信息共享、测试平台共享等制度,有利于形成科学技术路线、释放优秀方案潜力,从而降低协作成本、提升合作收益、激发创新投入、实现高效攻关.对科研机构和生产企业攻关协作的博弈模型论证了上述观点.     

Organizational climate for innovation and creative teaching in urban and rural schools

Due to the impact of knowledge-based economies, all countries strive to foster creative education. Research has demonstrated that creativity is influenced both by individual characteristics and by the environment. Previous research examining creative teaching by teachers in Taiwan has typically focused on the relationships between creative teaching and innovative personal characteristics, school leaders’ behaviors, and internal motivation. The purpose of this study was to move beyond prior research to investigate the relationship between creative teaching behaviors and innovation-fostering elements of the organizational climate in schools. In addition, we examined the impact on teacher creativity of urban versus rural school location.
