OPTIMAL MONETARY POLICY WITH THE STICKY INFORMATION MODEL OF PRICE ADJUSTMENT: INFLATION OR PRICE‐LEVEL TARGETING?

I investigate the optimal monetary policy in a New Keynesian macroeconomic framework with the sticky information model of price adjustment. The model is solved for optimal policy, and welfare implications of three alternative monetary policy regimes under this optimal policy are compared when there is a cost‐push shock to the economy. These monetary policy regimes are the unconstrained policy, price‐level targeting and inflation targeting regimes. The results illustrate that optimal policy depends on the degree of price stickiness and the persistence of the shock. Inflation targeting emerges as the optimal policy if prices are flexible enough or the shock is persistent enough. However, the unconstrained policy or price‐level targeting might be preferable to inflation targeting if prices are not very flexible and the shock is not very persistent. The results also show that as prices become more flexible, the welfare loss usually gets bigger.     

财政政策影响区域经济增长的实证研究——以西部大开发投资政策为例

基于中国省区水平上的面板数据,借鉴Kiel处理面板数据的方法,对西部大开发的物质资本和人力资本投资政策进行评估,结果表明:西部大开发的物质资本投入虽然促进了西部地区经济增长的速度,但是该政策并没有缩小东西部地区经济增长的差距,西部地区的经济增长仍然落后于东部地区的经济增长。西部大开发的人力资本投资政策并没有显示出其对西部地区经济增长的作用。     

银行业在区域经济市场化过程中的策略选择——以振兴东北老工业基地为例

振兴东北是从传统到现代、从计划到市场的经济制度变迁过程.货币政策的区域效应使银行业在东北这一特定区域市场化进程中有了采取区域性策略的可能.在分析东北的区域性经济特点的基础上,针对银行业自身改制和振兴东北的企业问题,本文提出了在东北经济市场化进程中的区域性银行业策略.     

科技金融政策能否降低环境污染？——基于“促进科技与金融结合试点”的准自然实验

在创新驱动城市发展的背景下,科技金融发展为生态环境治理提供了新动力和新方向。本文基于中国2003—2018年262个地级市数据,将“促进科技与金融结合试点”实施视为一次准自然实验,运用双重差分法考察了科技金融政策的环境治理效应及其影响机制。研究发现：首先,科技金融政策的实施对环境污染具有明显的抑制作用,并且与水污染相比,科技金融政策对于空气污染的治理效果更为明显;其次,从城市区位来看,科技金融政策对于东部和北部地区的环境治理效果要优于中部、西部和南部地区;从城市等级来看,科技金融政策对于高等级城市具有更为明显的治污排污效果;最后,中介效应分析表明,金融发展、技术创新和经济规模是科技金融政策改善环境的有效路径。此外,科技金融政策实施对于邻近地区的环境治理具有显著的空间溢出效果。上述分析首次尝试将环境污染纳入到科技金融政策的评估框架中,丰富和完善了环境治理的相关研究,有效地回应了学术界关于科技创新、金融发展和环境治理的争论,为推动经济高质量发展提供了经验证据。     

Venture capital,innovation, and growth: evidence from Chinese metropolitan data

Using panel data from 282 Chinese cities from 2003 to 2015, we estimate the impact of venture capital (VC) on innovation, employment, and payroll in metropolitan areas. Controlling for endogeneity, VC investments are significantly positively related to metropolitan innovation, employment, and payroll in a fixed effects panel regression and dynamic GMM estimation. Using the number of IPOs (Initial public offerings) in the city as an instrumental variable to again control for endogeneity, VC remains significant. Our results show that VC is significantly contributing to the metropolitan economy as a whole by supporting innovation, creating jobs, and generating wealth in the local cities.     

环境约束下转变我国外贸增长方式的机制与对策

中国对外贸易规模快速扩张的同时,主要出口行业的工业三废排放指标和主要出口口岸及地区的污染指标也随之上升,对资源和环境产生了负面影响。在当前资源环境约束下,对外贸易发展应该从环境输出走向环境修复,用循环经济理念指导生产经营,激励环境技术创新,实施战略性的环境措施和贸易措施,实现环境、贸易、可持续发展的三赢。     

经济开放度与货币政策有效性的实证分析

通过运用Karras建立的产出增长率和通货膨胀模型,采用向量自回归VAR框架,分析经济开放度对我国货币政策效果的影响。回归结果表明,无论是以M0作为货币政策的测度指标,还是以M1作为货币政策的测度指标,它们都反映出:在长期,经济开放度的提高会削弱货币政策的有效性;但从短期来看,经济开放度的提高不一定会削弱货币政策的有效性,有时反而会提高货币政策的有效性。     

基于生态学的工艺创新竞争博弈模型分析

分析了工艺创新竞争的先动者劣势、共生共荣性两大特点,以工艺创新能力的逻辑斯蒂增长模型为基础,基于生态学的捕食、竞争与竞合建立了相应的工艺创新竞争博弈模型,并分别探讨了博弈模型均衡解的稳定性。     

Central Bank Actions and Words: The Intraday Effects of FOMC Policy Communications on Individual Equity Volatility and Returns

We compare intraday impacts of the release of Federal Reserve decision announcements and of Federal Open Market Committee minutes between 2004 and 2015 on 1,997 equity return and volatility series. We find that returns are unresponsive to either news release, but conditional volatility increases for both, manifesting immediately after each information release, and persisting for 30 minutes post‐announcement. These effects are larger for decisions than for minutes. On stratifying firms by trading intensity, we find most “high trading intensity” firms respond to these announcements, while “low trading intensity” firms are less affected. Our results show that traders respond, albeit differently, to both sets of information releases.     

Innovation and HRM: Absences and politics

This article analyses the role of HRM practices in the implementation of an innovative cross-functional approach to new product development (concurrent engineering, CE) in Eurotech Industries. Contrary to CE methodology stipulations, and despite supportive conditions, HRM received scant attention in the implementation process. Organizational power and politics were clearly involved in this situation, and this article explores how their play created such HRM ‘absences’. The article builds on a four-dimensional view of power in order to provide a deeper understanding of the embedded, interdependent and political nature of HRM practice and innovation.
