Timing decisions of new product preannouncement and launch with competition

We develop a game-theoretic model to study the timing of new product preannouncement and launch under competition. We derive firms’ optimal timing choices and conducted a numerical analysis to evaluate the role of various factors. Our analytical and numerical results showed that anticipated competitor’s timing choices are the most significant factors. A firm should not preannounce early unless the preannouncement is effective in creating pent-up demands. However, the preannouncement and launch should be rushed if the quality or profit margin of the new product is high, and postponed if the market share of the existing product is high. The market leader should preannounce earlier in a simultaneous game than in a sequential game, but the opposite for the market follower. Data collected from the microprocessor industry validated our model.     

Effects of teleconferencing technologies: An exploration of comprehension,feedback, satisfaction and role-related differences

Several theoretical approaches have been put forth to predict and explain the effects of teleconferencing technologies. One approach is to examine the functions of nonverbal signals and to make predictions based on the fact that different teleconferencing technologies allow nonverbal communication to different extents. One of the functions of nonverbal signals is to allow the listener to provide feedback to the speaker in a communication. Prior research has shown that such feedback enhances listener comprehension. In this study, it was hypothesized that different teleconferencing technologies would allow different levels of feedback based on their ability to accommodate nonverbal signals, and this in turn would affect comprehension. An experimental study was conducted to compare comprehension, feedback, and satisfaction in telephone and computer conferencing. The study confirmed that comprehension and speaker satisfaction are related to feedback, but failed to show a relationship between listener satisfaction and feedback. No difference in comprehension, listener, or speaker satisfaction was observed across teleconferencing technologies. Role-related differences were observed between the speaker and the listener. It is suggested that the effects of teleconferencing technologies can be mapped systematically by examining each of the functions of nonverbal signals, one at a time.     

风险投资的资本退出与防范研究

1.风险投资的实质风险投资(venturecapital),在国外又称创业投资,是指将资金投入到快速成长的、具有高度不确定性的未上市中小企业,以期获得高收益的投资行为。风险投资家以专业知识主动参与经营,使被投资企业能够健全经营、迅速成长,风险投资家可在被投资企业成功后,将所持有股票卖出,收回资金及其高额利润,再投资于另一新创企业,复始进行中长期投资并参与经营。风险投资家以获取股息、红利及资本利得为目的,其最大特征是甘冒较大风险以获取巨额资本利得。与其他投资相比,风险投资的特殊性在于其投资收益是通过转让风险企业的股权而实现增…     

Some remarks on the construction of independent identically distributed random variables,Markov chains and martingales

In this note, we make some remarks on the construction of sequences of independent identically distributed random variables and of Markov chains concretely on a probability space (Ω,A,P). We also show that there are non non-trivial martingales of exponential type.     

Ethical decision making: An investigation of services marketing professionals

This study investigates the relative influences of professional values and selected demographic variables on the ethical perceptions of services marketing professionals. The relationship between ethical perceptions and ethical judgments of service marketers is also examined. The data were obtained from a mail survey of the American Marketing Association's professional members of service industries. The survey results indicate a positive relationship between a service professional's professional values and his/her perceptions of ethical problems. The results also suggest that ethical judgments of a service professional can be partially explained by his/her perceptions of ethical problems. Implications of the research findings were discussed.
