Complementarity, coordination and compatibility: The role of fixed costs in the economics of systems

We analyze industry equilibrium and incentive to compatibility when goods produced by different producers generate utility only when consumed as component parts of a system. We assume the presence of two systems, each composed of some basic component and a set of differentiated complementary products. The combination of complementarity between the two components of the system and of fixed costs in the production of the complementary product results in a form of network effect. We focus on the role played by the size of the fixed costs in the production of the complementary products in determining the size of this system effect and, by this means, the structure and types of equilibria that may be observed: monopolistic or duopolistic, symmetric or asymmetric. We also highlight the consequence of the same fixed costs for the private and social incentives to render the systems compatible.     

税收优惠对外商投资影响的研究综述

税收优惠是各国政府用来吸引外商投资的常用手段。但是,税收优惠如何影响外商投资历来就是一个充满争议的话题。早期国际上关于税收优惠对外商投资影响的经典理论主要有庇古的福利经济学理论、“双缺口”模型和邓肯的国际折衷理论,而近来也有不少国内外学者分别从区位选择、融资来源、投资类型和投资形式等角度论证了税收优惠的作用。     

在华外资银行发展对我国经济增长的影响分析

随着外资银行在我国的发展与壮大,外资银行对我国经济的影响也逐渐增强。本文从正反两个方面探讨了在华外资银行发展对我国经济增长的影响,认为在华外资银行的发展一方面给我国经济增长带来了积极的正面效应,另一方面也带来了一定的不稳定因素。因此,我国应该采取一定的措施最大限度地发挥在华外资银行对我国经济增长的积极作用,严格控制在华外资银行对我国经济增长的不利影响。     

论我国机构投资者对股票市场的反稳定作用

运用数理统计的基本原理，指出导致近几年中国股市非理性下跌的最直接原因，是以证券投资基金为主的机构投资者超常规发展。在目前的情况下，不宜继续提倡大力发展机构投资者，应努力恢复股票市场对中小投资者的吸引力，实现中国股市投资主体之间的“生态平衡”，从而支持中国股市长期稳定和谐发展。     

企业模块化的边界及其经济效应研究

作为一种分析工具，模块或模块化的涉及范围和利用能力非常强大。尤其是在信，皂，技术快速发展和需求日益个性化的知识经济时代．对模块化理论的重新解读和运用，更有助于我们认识新经济现象的本质特征。大量的研究已显示．企业模块化以后形成了一种全新的组织形式，而且带来了许多令人想像不到的效果。但这并不意味着对企业模块化研究的终结。本文试图在经济学理论和模块化理论融合的基础上．探究企业模块化的形成机理，企业模块化的最佳边界．以及企业模块化后究竟带来了怎样影响三个核心命题。     

The Friday Effect in European Securitized Real Estate Index Returns

This study extends research on the day-of-the-week effect towards European real estate indices. We examine this anomaly for several European securitized real estate index returns between 1990 and 2003. Although the countries under analysis have unique country-specific patterns, we find that eight out of eleven European countries exhibit abnormally high Friday returns. Moreover, two different Europe indices also exhibit the Friday anomaly. The anomaly is robust with respect to extreme observations, alternative specifications and several well-known calendar effects.     

Contagion or Competition: Going Concern Audit Opinions for Real Estate Firms

We examine whether intra–industry information transfers from going–concern audit opinion announcements create contagion or competitive stock price reactions for other real estate firms operating in the same line of business. Using returns from publicly-traded land subdivision/development firms and Real Estate Investment Trusts, we find modest evidence supporting a competitive effect among rival firms as a result of another real estate firm announcing the receipt of a Going Concern Opinion (GCO) from its independent auditors.     

Board Members and Company Value

This essay surveys research about the value of individual members of boards of directors. When directors join or exit corporate boards, company stock prices respond, often in magnitudes of 1% of firm value or more. Related research shows that when a significant event impacts the stock price of one company, the effects are transmitted to other companies that share board members in common with the primary company. Share price reactions are sensitive to variables such as a director’s occupation, independence, and professional qualifications. Together, this evidence suggests that a well-functioning market for directors might already exist, making direct regulation unnecessary and possibly counter-productive.     

A multilateral approach to examining the comovements among major world equity markets

This study investigates the comovement in stock indices among major developed markets, where Morgan Stanley Capital International (MSCI) indices are employed for the purposes of the study. We employ a model that accommodates multilateral international impacts on equity index movements. The empirical results reveal the existence of significant international transmission effects among these major world markets, both in terms of returns and volatility, and mostly in a positive direction. The U.S. market, as expected, is the leading market in the sense that it has the most pervasive and significant impact on all markets across continents. However, the U.S. market exhibits a different relationship with European markets from that with Asia-Pacific markets. The evidence also suggests that strong regional transmission effects exist. A further investigation using the extended model reveals that the linkages between U.S. and European markets are driven by positive global common forces and by negative international competitive effects. On the other hand, the U.S. and Asian markets are linked through positive global common forces and positive international contagion effects. The United States, Canada, and the U.K. are the three markets that still demonstrate contagion influence over countries outside its own region. The Asia-Pacific markets are more susceptible to contagion effects. Finally, it is interesting to find that Japanese market performance became more contagious toward other markets during the Asian financial crisis period.
