市场营销蒙授专业人才培养模式改革的探索

市场营销蒙授专业现有人才培养模式存在着培养目标单一、生源基础不同的学生使用同一套培养方案、专业课设置面窄过细、实践教学环节薄弱等弊端,限制了学生个性的发展,导致学生消极对待学习,影响学生实际操作能力的锻炼和提高,难以适应就业市场的多样化需求。因此,必须通过确立多样化的培养目标、制定个性化的人才培养方案、构建合理化的人才培养质量评价体系、打造高水平的师资队伍、强化教学运行管理、重视对蒙汉双语授课专业学生的管理等措施,对蒙汉双语授课学生因材施教、个性化培养,才能适应社会对少数民族人才的多样化需求。     

Whose firm is it anyway? Analyzing ownership effects on IPO performance

This study revisits current practice that ownership holding at IPO has a homogeneous impact on IPO performance. Using signalling theory, we develop and test a conceptual model explaining the relationships between the aggregated ownership structure and IPO price premium. We argue that aggregated ownership has a direct effect on issue price premium, and offer specific hypotheses on the effect of the shares sold during the offering by each type of owner on IPO performance. We use archival data from a sample of US firms that issued IPOs between 1996 and 2000 and find a significant direct effect of ownership configuration, namely, heterogeneity in effect of each ownership type on IPO performance as well as interaction effects between different ownership types.

Protecting Intellectual Property Rights: The Special Case of China

China is the largest source of counterfeit goods. Both U.S. and European Union customs statistics put the People's Republic of China at the top of the list of pirated product seizures. Along with the remarkable growth in the Chinese economy and exports has come the growth of counterfeit product production and distribution throughout the world. To present a full picture of the many intellectual property rights (IPR) protection problems in China this article reviews Chinese history and traditional attitudes toward individual ownership of IP under Confucianism and communism. Finally, the article presents a view of the current enforcement of IPR rights in China describing the major difficulties encountered by rights owners.     

Return and risk in initial public offerings of both shares and warrants

In the past few years there has been an increasing number of new issues of shares of common stock together with warrants intended to raise interest in initial public offerings of relatively young, growing firms. In this study we examine the pricing efficiency of stocks and warrants offered simultaneously to the public as a single unit. We present a model for evaluating the warrants in such offerings and test it empirically against data from the Tel-Aviv Stock Exchange, where such offerings have become standard. We find that the issued units are usually undervalued, allowing for significant abnormal positive returns. But, while the warrants are usually underpriced, the stocks are overpriced. Largely consistent with the evidence from other financial markets around the world, we also find abnormal negative rates of return in the long run.     

The Diversification Effects of Initial Public Offerings

Abstract:  A firm's stock becomes publicly tradable through an initial public offering (IPO). This study suggests a portfolio diversification perspective to explore IPOs. We examine whether investors can gain diversification benefits by adding an IPO portfolio to a set of benchmark portfolios sorted by firm size and book-to-market ratio. Using US IPOs from 1980-2002, we find that adding a value-weighted IPO portfolio does lead to a statistically and economically significant enlargement of the investment opportunity set for investors relative to investing solely in a set of benchmark portfolios. Specifically, the Sharpe ratio of the tangency portfolio increases by 5.50% on average after including IPO stocks. Furthermore, IPOs associated with prestigious lead underwriters are the main source of this augmentation of the mean-variance investment opportunity set. Finally, our study implies that issuing IPO exchange traded funds or similar products can provide diversification gains to investors.
