县域经济增长中结构红利的测度及决定 ——基于中国1 820个县面板数据的实证分析

产业结构升级是经济增长的源泉之一。本文基于中国1 820个县的面板数据,采用Translog生产函数估计要素弹性,进而测度县域经济增长中的结构红利,同时构建空间误差计量模型对结构红利的影响因素进行检验。研究结果表明2002-2010年间,结构红利占县域GDP总值的444%,对县域GDP增长的贡献达到了2435%。劳均资本、劳均土地等变量对结构红利有显著影响,本文还发现,在东部、中部、西部三个地区,财政支出占GDP的比重对结构红利都有显著的负向影响。     

Product Patent Reform and its Impact on Korea's Pharmaceutical Industry

Our analysis focuses on the effect of U.S. government pressure on Korea to adopt product patents for chemical and pharmaceutical products. American pressure began in November 1985 and ended with the Korean Legislature's passage of a new patent law in December 1986. We conduct an event study of the effect of the new patent law on the value of Korean pharmaceutical firms listed on the Korea Stock Exchange. Regression analysis shows that the new law induced excess returns of-74 percent over the 14-month analysis period. The results suggest that adoption of stronger patent laws reduced Korea's wealth.

A Study of Mathematic Model to the Development of Regional Industry Cluster

This paper analyzes the factors that influence the development of regional industry cluster, which are location factors, accumulatable factors, and external factors. Then regarding the similarity between the development of industry cluster and biology community, a modified logistic model is built, and a field study is made between the real instances and the model.     

On the welfare costs of misspecified monetary policy objectives

This paper quantifies the effects on welfare of misspecified monetary policy objectives in a stylized DSGE model. We show that using inappropriate objectives generates relatively large welfare costs. When expressed in terms of ‘consumption equivalent’ units, these costs correspond to permanent decreases in steady-state consumption of up to two percent. The latter are generated by both the inappropriate choice of weights and the omission of variables. In particular, it is costly to assume an interest-rate smoothing incentive for central bankers when it is not socially optimal to do so. Finally, a parameter uncertainty decomposition indicates that uncertainty about the properties of markup shocks gives rise to the largest welfare costs.

融资约束条件下我国中小板上市公司投资效率测度

文章以我国中小企业板上市公司为研究对象,从企业经理人追求利润最大化行为出发构建中小企业的投资支出模型。不同于已有文献仅从投资-现金流敏感性角度入手的实证研究,文章的研究方法无需对样本公司进行分组,而且可以定量测度融资约束条件下的公司投资效率问题。实证结果表明：由于融资约束的存在,使得我国中小板上市公司实际投资支出最优水平低;现金流的增加不仅可以缓解融资约束压力,还能够降低融资不确定性,债务融资比例越高,融资约束越大,进一步加剧了未来融资时的不确定性;我国中小板上市公司融资约束程度与企业规模呈负相关关系,且投资效率随时间呈现下降趋势,意味着近年来我国出台的一系列旨在改善中小企业融资难的政策措施,在实践中并没有起到有效缓解融资约束的作用。     

国外责任制研究综述:从单层次到多层次的研究视角

The impact of supplier development on buyer competitive advantage: A path analytic model

As manufacturing firms increasingly realize that supplier performance is crucial to their establishing and maintaining competitive advantage, supplier development has been a subject of considerable research in supply chain management. We develop and test a path model to explore how supplier development practices affect buyer-supplier performance from the buying firm's perspective in the context of Hong Kong's electronics industry. The results show that top management, supplier evaluation, and supplier strategic objectives are significant determinants of transaction-specific supplier development, and that buyers that have closer collaborative relationships with suppliers may strengthen their competitive advantage.     

The Decline of Antitrust Enforcement

American Antitrust policy has abandoned tight restrictions on mergers and on a variety of business practices, such as vertical restraints indistribution. I argue that the change is permanent for three reasons: 1)rising skepticism about government intervention generally, 2) lack ofdeleterious effects from the new policy, and 3) increasing irrelevance ofantitrust in global markets. Due process considerations will reinforce thechange in policy. New technologies may, however, revive traditionalantitrust concern with price fixing.
