Quantitative growth effects of subsidies in a search theoretic R&D model

Should government subsidize R&D and does it matter how these subsidies are allocated? We examine these questions in a dynamic model where R&D is described as sequential sampling from a distribution of new ideas. Successful discoveries affect future available resources and incentives for further R&D. Consequently, there may be under-investment in R&D. We study the effect of government interventions aimed at fostering growth through R&D. Calibrating the model with aggregate data from the Israeli business sector allows us to quantitatively compare two forms of support resembling those actually used to encourage R&D in the Israeli business sector: (i) an unrestricted subsidy that may be used at the recipients' discretion to finance R&D or other investments, (ii) a subsidy earmarked by the government for R&D activities only. While there is no theoretical way to determine which of the two subsidies will have a greater impact on search for new ideas and growth, we find that in the calibrated economy both subsidies have a significant but similar impact on the economy's output and TFP growth rates. Accordingly, in the case of the Israeli business sector, the incentives to conduct R&D were sufficiently strong, and no R&D-specific encouragement was needed. However, a sensitivity analysis reveals that for economies characterized by other parameter values this result may not be true. Correspondence to: B. Bental     

制度变迁、技术进步与经济增长——一个总结性分析框架

制度变迁和技术进步是长期经济增长的两个最为重要的变量,但是却没有这方面的理论模型。正是基于这个原因,笔者把制度变迁和技术进步统一进了一个新的经济增长模型。讨论结果表明,该模型符合经济增长理论和新制度经济学中已成定论的观点。     

中国金融控股公司发展模式的新制度经济学分析

随着区域经济一体化和金融全球化的加强,金融控股公司混业经营所带来的规模经济性日趋强化,从而成为金融业发展的一种重要组织形式,从本质上反映了各国金融业和政府制度面向新的前景而作出的相应战略性调整,初步展开了21世纪世界银行业的市场结构与竞争态势。这种态势为中国金融业的发展和中国金融控股公司模式的选择提出了外在的要求。同时,中国的金融业将在WTO的框架下融入全球金融市场,中国的金融业也要走向世界,在国际金融市场上成长壮大,这就要求中国金融业必须与国际惯例接轨。     

论我国上市公司董事会治理结构存在的问题与对策

我国上市公司董事会治理在董事会机构、董事会会议、独立董事、董事会外部制约机制等方面都存在一定问题.解决的对策是:增强董事会的独立性,改变大股东完全控制董事会的局面;加强独立董事制度建设,营造独立董事充分行权的环境;加强对董事的违规处罚力度,强化董事的诚信意识;建立科学合理的董事会考评机制.对于董事会的考核可以从两方面去进行:一方面是对董事会的整体考评,另一方面是对董事个人的考核.我国可以借鉴美国的考核评估方法,由非投资相关者专门针对董事会进行考核评估.     

西部区域层级增长极网络发展战略构想

在对增长极理论、点轴理论以及网络开发等理论文献深入研究的基础上,提出西部应走层级增长极网络开发模式,并提出了构建以“成渝”和“西咸”经济圈为核心层增长极的西部区域层级增长极网络,在实现生产与人口向“辐射带”地理集中的基础上,利用“网络”的极化效应与回波效应促进层级增长极网络辐射带的发展,最终达到推动整个西部区域经济发展的目的的设想。     

R＆D、R＆D溢出、内生增长和内生收敛

根据强调知识与技术创新、知识与技术溢出重要性的当代内生增长理论，本文建立了一个将R＆D和R＆D溢出与资本积累之间、R＆D和R＆D溢出与总产出增长之间直接关联起来的动态模型。面板数据协整检验实证分析结果表明R＆D和R＆D溢出与资本积累之间、R＆D和R＆D溢出与总产出增长之间分别存在显著的正面长期协整关联。进一步的分析表明，R＆D与资本积累之间、R＆D与总产出增长之间分别存在显著的长期双向格兰杰因果关系。由此观知，R＆D乃长期经济增长源泉之所在。另一方面，尽管资本积累或总产出增长并不格兰杰导致R＆D溢出，证据表明R＆D溢出格兰杰导致资本积累和总产出增长。这种由R＆D溢出到资本积累和总产出增长的单向格兰杰因果关系意味着尽管知识与技术的跨国传播并非必然发生。其实为世界经济增长的重要动力。     

Does too much government spending depress the economic development of transition economies? Evidences from dynamic panel threshold analysis

This paper investigates the relationship between government size and economic growth and determines the optimal level of government spending to maximize economic growth. The paper applies a dynamic panel data analysis based upon a threshold model to test the threshold effect of government spending in 26 transition economies over the period spanning 1993–2016. According to the analysis results, government expenditures have a threshold effect on economic growth, and there is a non-linear relationship depicted as an Armey curve in these transition economies. The findings indicate that a government size above the threshold government spending level adversely affects economic growth, while a government size below the threshold level has a positive effect. Furthermore, there is a statistically significant relationship between the two variables above and below that optimal level, even if we divide the sample into developed and developing countries. Our findings suggest that governments in transition economies should consider optimal government size at around the estimated threshold level to support sustainable economic growth.     

生态需要与发展的理论研究

生态需要是人类三大需要的支柱之一，也是人类持久发展的动力源。正是人类的生态需要导致了人类发展观念的五种更新，促进人类需要结构的合理化，推动人类社会整体前进。     

经济增长的变化本质

在过去的一个世纪中,富裕国家的经济本质已经发生了巨大的变化。因此,文章提出“技术生理演变(technophysio evolution)”概念,即快速技术变化和人类生理进步的协同作用。这主要表现在以下三个方面：(1)消费结构和工作体闲时间分配的改变;(2)经济和家庭产出分配方面受高水平经济成就的影响;(3)全球市场迅速急剧转向耐用消费品和高科技服务。     

比较优势理论与农业区域专业化发展——以福建省为例

应用比较优势理论探讨农业区域专业化发展问题。理论推导得出,按照区域农产品生产优势来选建农业专业化部门能够实现农业增效,提高农业生产整体水平。以福建省为例,采用区位商和平均值法分析了主要农产品生产比较优势。结果表明,福建省多数县份的一种或几种农产品具有显著比较优势,农业生产的区域专业化已现端倪。但目前大多数县份主导产品不显著,专业化生产与农业资源禀赋不相协调。按照县域农产品的比较优势创建农业专业化部门,将是福建省解决"三农"问题和协调县域之间经济发展的有效途径。
