International interest rates and US monetary policy announcements: Evidence from Hong Kong and Singapore

This paper investigates the responses of market interest rates to US monetary policy announcements for the US and two emerging economies, Hong Kong and Singapore which are similar on many respects but have experienced opposite exchange rate regimes in the last twenty years. Our results, based on market expectations extracted from federal fund futures rates, document that FOMC announcements significantly affect the term structure of interest rate in the US and both Asian countries. Further, international interest rate differentials around FOMC meeting dates tend to be negative for short maturities with the impact gradually dissipating as bond maturity increases. Finally, for the case of Singapore, we find that domestic interest rates react to both external and domestic monetary policy announcements with a magnitude that is larger over the full bond maturity spectrum for domestic announcements. These results are robust to time-varying futures risk premia and alternative measures of interest rates expectations.     

论董事会的独立性对上市公司治理结构的完善——独立董事的产生及现状分析

现代公司制度的核心是要建立起完善的公司治理结构,董事会在公司治理结构中起着核心作用。但随着股份公司的股权进一步公众化,越来越多的研究报告揭示了董事会职能减弱的客观事实;同时,董事会日渐形成的内部控制与现代企业的发展形成矛盾。由此,西方在公司治理结构上引入了独立董事制,独立董事的功能已在现代企业法人治理结构中确立。     

从美国公司财务假帐丑闻看公司治理和社会制约的完善

美国公司财务假帐频繁产生的原因有：公司管理制度和公司治理结构方面的变化对企业的约束力下降在社会中介机构的独立审计制度下部分中介机构与造假公司同流合污，法律制度的缺陷与不完备，以及政府对企业投资银行和征券行业的监管机制不健全等。有鉴于此，我国公司应建立、健全监音管理机制，并加强公司内部控制。

战后日本对外贸易发展的动态比较优势分析

二战后日本经济从一片废墟中迅速崛起成功跻身于发达国家行列，其对外贸易在战后的50多年间一直保持着稳定的增长。日本出口商品结构沿着劳动密集型、资本密集型、知识和技术密集型的轨迹发展，逐步升级，顺应了世界经济产业结构调整的步伐，为其对外贸易的持续发展奠定了坚实的基础。日本对外贸易遵循的是动态比较优势原理，其经验对我国当前外贸发展具有重要的借鉴意义。

Likelihood-based specification analysis of continuous-time models of the short-term interest rate

An extensive collection of continuous-time models of the short-term interest rate is evaluated over data sets that have appeared previously in the literature. The analysis, which uses the simulated maximum likelihood procedure proposed by Durham and Gallant (2002), provides new insights regarding several previously unresolved questions. For single factor models, I find that the volatility, not the drift, is the critical component in model specification. Allowing for additional flexibility beyond a constant term in the drift provides negligible benefit. While constant drift would appear to imply that the short rate is nonstationary, in fact, stationarity is volatility-induced. The simple constant elasticity of volatility model fits weekly observations of the three-month Treasury bill rate remarkably well but is easily rejected when compared with more flexible volatility specifications over daily data. The methodology of Durham and Gallant can also be used to estimate stochastic volatility models. While adding the latent volatility component provides a large improvement in the likelihood for the physical process, it does little to improve bond-pricing performance.     

创新型企业组织形式的设计

创新型企业在组织构成上与传统企业有很大的不同，它是为了达到技术和产品创新的目的，在不同专业领域进行一定方式的分工和合作的一批高素质技术人员的集合。因此，在组织上，创新型企业就要不同于传统企业的直线职能式的组织结构。经研究，它应以项目组为组织的基本单元，建立矩阵式的组织结构，充分利用人力资源，灵活、快速地适应环境的变化。
