基于经济区视角下的区域金融发展与经济增长关系的实证研究——以京津冀经济区为例

本文从跨行政区的经济区的视角来研究区域金融发展与经济增长之间的关系,采用协整检验和因果关系检验对以京津冀经济区进行实证研究。检验结果显示:在京津冀经济区金融规模与金融效率对经济增长存在正相关性,但是,两者对经济增长的促进作用并不显著。金融规模与经济增长之间不具有因果关系,而经济增长与金融效率之间存在显著的单向因果关系。说明京津冀经济区的经济增长与金融深化发展遵循的是需求引致型发展模式。

Optimal freeware quality in the presence of network externalities: an evolutionary game theoretical approach

New software products often face difficulty in achieving market penetration. A potential remedy is to offer a freeware version of the software to encourage initial adoption and establish a larger user base for the software, thereby increasing the commercial version's value to adopters in future periods. However, to avoid complete cannibalization of the commercial version, the freeware version's quality must be sufficiently low and the price of the commercial version must not be too high. We model the effect of these two decision variables, price and freeware quality, on the adoption of software using static and evolutionary game theory.     

非上市中小企业融资约束问题研究——基于修正的FHP模型的分析

在FHP模型的基础上,结合我国非上市中小企业的特性,对FHP模型的变量进行修正,建立了适于我国非上市中小企业融资约束的识别与估计的分析框架。以产能利用率为控制变量,超额现金流为解释变量,对非上市中小企业融资约束进行度量,其实证结果是显著的。     

Freeware as a competitive deterrent

Using perfect foresight and adaptive models, this paper examines the effect of competitor asymmetry, consumer sensitivity to incentives and adaptive processes on freeware strategies and competitive outcomes. Four roles played by freeware in competitive markets are identified – it can be a mechanism to build or speed up the growth of a network without the need to lower prices on the commercial version, a deterrence mechanism, a hindrance to a rival’s network building efforts, and a coordination device in the presence of forward looking consumers. We determine the optimal prices of the commercial version, the decisions to introduce freeware and the freeware qualities for both competing firms.
