保险业发展运行中亟待解决的若干问题

保险业在连续多年的快速增长后面临着一系列亟待解决和突破的重大问题,包括发展与转型、区域发展不均衡、如何学习与借鉴国际先进经验、风险防范与支持业务发展、一盘棋与差异化、外部环境配套等问题.保险业的快速发展要兼顾业务结构调整和产品转型.区域发展不均衡既是问题,也意味着中西部存在良好的发展机遇;学习与借鉴国际先进经验要结合中国实际,逐渐推进;风险防范与支持业务发展是辩证统一的关系,不是对立不可调和的;一盘棋思想与差异化政策应该有机结合使用,不可顾此失彼;税收优惠政策的突破与投资渠道的进一步放开是满足广大人民群众保险保障需求和促进保险业健康发展的重要外部环境条件.

我国区域金融结构转变与区域经济发展的实证分析

本文首先用格兰杰因果检验方法分析了我国区域金融结构转变与区域经济发展之间的关系,得出我国区域金融结构转变是被动的适应区域经济发展的结果,而不是导源于金融的自由化。然后针对分析结果提出优化我国区域金融结构的建议。     

东亚“雁阵模式”式微原因新析及启示

经济全球化时代,维系“雁阵模式”运行的宏观背景条件正在丧失,“雁阵模式”开始走向终结。日本经济的“制度疲劳”、“四小龙”的兴起、中国的崛起以及亚洲金融危机只是“雁阵模式”式微的表层原因,其真正原因是经济全球化及其机制的作用:即全球信息化、世界经济一体化、跨国公司的发展、知识经济在世界范围的兴起,成为“雁阵模式”终结的力量。“雁阵模式”的终结对于中国产业结构调整与优化,具有重要启示作用。

Swimming with the Tide: Solidary Wage Policy and the Gender Earnings Gap

This paper addresses the consequences of wage compression for the gender wage gap in Sweden during the period 1968–1991. We find that the effects of changes in the wage structure on women's wages have varied over time and have been partly counteracting. Changes in industry wage differentials have systematically worked against women, while changes in the returns to human capital and unobserved characteristics have contributed to reductions in the gender wage gap. Changes in the wage structure were particularly important between 1968 and 1974 when there was a dramatic reduction in overall wage inequality.

特征尺度理论与企业发展战略的层级结构

本文根据系统学思想，首先论述了经济系统特征尺度的基本理论，给出了系统经济学关于短期和长期的严格定义。在此基础上，提出了企业发展战略的层级结构。根据时间区间的长短，区分了企业战略的五种不同情况，指出企业家在什么情况下应当关注自身企业管理，产业（行业）变化，区域经济变化，国家经济变化和全球经济变化等。同时，也指明了不同层次的企业战略所对应的不同经济学分支。     

On the use of measure-valued strategies in bond markets

We propose here a theory of cylindrical stochastic integration, recently developed by Mikulevicius and Rozovskii, as mathematical background to the theory of bond markets. In this theory, since there is a continuum of securities, it seems natural to define a portfolio as a measure on maturities. However, it turns out that this set of strategies is not complete, and the theory of cylindrical integration allows one to overcome this difficulty. Our approach generalizes the measure-valued strategies: this explains some known results, such as approximate completeness, but at the same time it also shows that either the optimal strategy is based on a finite number of bonds or it is not necessarily a measure-valued process.Received: November 2002, Mathematics Subject Classification: 60H05, 60G60, 90A09JEL Classification: G10, E43The first author gratefully acknowledges financial support from the CNR Strategic Project Modellizzazione matematica di fenomeni economici.
