Flypaper Effect and Sluggishness: Evidence from Regional Health Expenditure in Italy

In Italy, public expenditure reduction is achieved through a revision of social security and health care programs. In particular, public health expenditure control has been implemented through a reform that imposes more stringent budget rules to local governments and a considerable reduction in grants-in-aid from the central government. This paper investigates empirically whether the response to this decrease in categorical lump-sum grants from the central to local governments results in an asymmetric response to intergovernmental grants. Hard budget and soft budget constraint hypotheses are estimated by using a sample of cross-sectional and time observations covering the 20 Italian regions over the period 1989–1993. The main finding is the existence of a standard and a super flypaper effect in both models. The introduction of the soft-budget constraint hypothesis results in a stronger effect of grants and a lower response of own resources which shows that local governments prefer to incur some deficit instead of reducing health care expenditure.     

Money and exchange rates in the Grossman-Weiss-Rotemberg model

We analyze the impact of monetary policy on inflation, interest rates and exchange rates in a model with segmented asset markets developed by Grossman and Weiss (1983) and Rotemberg (1984, 1985). We find parameters for which real and nominal exchange rates in this model are (1) much more volatile than interest rates, inflation rates, and money growth rates, (2) highly correlated with each other, and (3) highly persistent. While this model fails to match the data in other important respects, it illustrates a potentially useful approach to modelling exchange rate behavior.     

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。     

模块化组织价值创新:原理、机制及理论挑战

本文借鉴瀑布效应原理，通过对需求导向下协调生产规则的演变、生产控制权追逐下旗舰企业地位的形成．以及迂回生产链加长条件下报酬递增等模块化组织价值创新机制的研究．指出企业与市场握手地带是一种专业化分工与一体化分工并存、报酬递减与报酬递增并存和外生不确定性化解与内生不确定性提高并存的双重世界。这将使企业与市场握手地带的传统企业理论因双重性而受到挑战。     

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.
