Unemployment and the business cycle in a small open economy: G.M.M. estimation and testing with French data

What is a relevant model for the European business cycle? In this paper, the empirical performances of three models are compared: a canonical Walrasian R.B.C. framework, its extension to the case of a small open economy, and a version of this model with search and wage bargaining on the labor market. Structural parameters of the models are estimated using G.M.M. and their abilities to reproduce the French business cycle, taken as representative of the European business cycle, are tested. Only the small open economy with unemployment is able to generate theoretical moments that match their empirical counterparts.

制约央行公开市场业务开展的若干因素与改革取向

根据公开市场业务在我国的具体实施状况，应深入考察了影响我国公开市场业务以及货币政策有效施行的若干制约性因素。进一步深化与完善我国公开市场业务操作的改革取向应是：（1）稳步推进利率市场化改革进程；（2）加快货币市场与资本市场的改革与发展；（3）努力提高货币政策制定与实施的独立性与科学性。

我国科技中介信息服务国际化若干思路

为了加快我国科技中介信息服务国际化进程,首先应积极构建联系我国区域之间的科技中介信息服务体系,尤其是开放式科技中介信息中心的建设。其次是构建我国联系各类创新主体在境内、境外之间的科技中介信息服务体系,加强与境外科技中介机构的信息交流;在此基础上,加快构建联系我国本土企业与跨国公司之间的科技合作的"桥梁",逐步形成开放式科技中介信息服务网络。     

开放经济条件下人民币反替代现象的实证研究

由于在我国金融开放程度不高,货币反替代的畸形发展给当前宏观经济调控造成了极大的挑战。本文通过对“货币需求的资产组合理论”模型的拓展,采用Johansen的协整方法检验变量之间的协整关系,建立我国货币反替代模型,发现货币反替代的出现主要是因为近年来我国经济持续快速稳定增长加大了国内外居民对人民币的信心所引起的。进而针对货币反替代给我国经济生活带来的危害,提出应采取的措施。     

新凯因斯DSGE模型与货币政策法则之汇率动态分析

对于小型开放经济而言,当经济存在价格僵硬的情况下,中央银行在面对不同冲击发生时,各政策法则执行对汇率波动的影响及动态调整过程差异较大。从中国台湾地区的情况为案例来看,在稳定汇率波动方面:当国内技术冲击时,货币法则优于利率法则;当国外通货膨胀时,利率法则优于货币法则;当国外利率冲击时,执行利率法则或货币法则,其结果无显著差异。在汇率动态调整方面:当国外利率调升时,中央银行执行利率法则与货币法则下,汇率的瞬时反应为过度贬值;当国外物价膨胀时,执行利率法则与货币法则下,汇率的瞬时反应表现为立即升值;当国内技术进步冲击时,因为国外冲击对小型开放经济体系影响力道较强,使得国内技术进度对体系的影响相对较小,其中在利率法则下,汇率微幅贬值,而在货币法则下,汇率微幅升值。     

开放式基金与证券市场健康发展

开放式基金是世界基金业中的主流品种 ,与封闭式基金相比具有很多优势。中国在2000年10月推出了开放式基金试点办法 ,可以预见 ,随着开放式基金发展壮大 ,我国证券市场将会发生深刻变化。为使开放式基金成功运作 ,必须重点关注其流动性风险 ,加强流动性风险管理。     

公开市场操作:国债与央行票据替代性分析

本文认为由于国债安全性高、收益稳定,尤其是短期国债具有期限短、变现性强、市场表现活跃等特点,符合公开市场操作的要求,理应成为央行公开市场操作的主流工具。目前,央行票据作为操作工具的局限性显现,国债具有的优势可弥补其局限。长远看,随着短期国债规模的扩大,央行票据将淡出,国债将成为公开市场操作的主流工具。但当前国情下,国债与央行票据短期内不可能完全替代,二者可能在一定时期内并存。     

Beyond absorptive capacity in open innovation process: the relationships between openness,capacities and firm performance

The literature has shown that open innovation (OI) can be a winning strategy in improving firm performance. However, in order to adopt and implement it, managers need to resolve practical problems, such as understanding the role played by OI capacities and openness on firm performance. In response to these needs, this study aims to investigate the hierarchical relationships between openness, OI capacities and performance using a structural equation model approach. This paper also attempts to compare the levels of openness between firms in different industries to discover similarities and differences in OI phenomena. The analysis of data obtained from a survey of Korean firms shows significant interrelations between openness, OI capacities and firm performance. Our results go further in developing understanding of the building blocks on which successful OI is built and particularly suggest that desorptive capacity which underpins the out-bound OI process, is in turn strongly supported by knowledge management capacity. It is hoped that the results of this study can enrich our understanding of the OI mechanism and provide managerial and policy implications.
