产业组织角度的合作R＆D研究述评

合作R＆D是企业整合研发资源的有效组织形式。本文对产业组织角度的合作R＆D研究进行了较为细致的综述。首先列举了对合作R＆D理论具有一定影响的经验研究；然后梳理了产业组织角度的合作R＆D主流理论；之后介绍了较有代表性的非主流理论研究；最后是全文结论和留待进一步研究的论题。     

一项关于价格水平决定的财政理论的实证研究

本文遵循Sala的五变量VAR方法发现,在绝大部分时间里,实际利率对一个标准差的实际税收正向冲击的反应为正,这就为价格水平决定的财政理论提供了来自中国的经验证据的支持。除此之外,与很多学者一样,本文还发现了实际税收冲击的非凯恩斯效应。     

我国央行沟通及效应分析

20世纪90年代中期以来,我国央行采取了一系列措施提高货币政策透明度,加强与公众的交流与沟通,取得了如下较好的政策效应：央行的政策目标偏好被公众所了解,有助于稳定公众通货膨胀预期;增强了公众对货币政策的理解与支持;增强了政策的可预测性;提高了央行的威信。不过,由于央行沟通还不够充分。其沟通应有的政策效应并未充分发挥出来,所以有必要进一步改善央行的沟通,以有效引导公众与市场预期,增强政策的有效性。     

中国对外直接投资的区位选择--基于经济增长的视角

利用2003-2011年中国对28个国家的对外直接投资面板数据,基于经济增长的视角,检验了中国对外直接投资的区位选择因素。结果显示,与东道国的贸易联系有助于中国对外直接投资,市场规模对中国对外直接投资具有显著的正影响,而劳动力工资水平影响不显著,经济增长对中国对外直接投资具有显著的负影响。基于实证研究结果,本文提出了现阶段促进中国对外直接投资的建议。     

Productivity changes in pre-crisis Western European banks: Does scale effect really matter?

Insofar as the completion of the Single Market for Financial Services, it has presented new challenges for European Banking industries. In this study, we use a recently developed generalized metafrontier Malmquist productivity index (gMMPI) to provide insights on productivity growth. We extend the gMMPI to broaden the index's capacity by decomposing various sources of productivity change in the metafrontier context. The sample contains commercial banks from 12 Western European countries prior to the recent financial crisis. A key advantage of our extension is that it introduces the role of scale effects. The empirical results show that an average bank's productivity growth arises mainly from technical changes and scale effects. Moreover, smaller and larger banks grow faster than medium ones. In addition, conservative banks tend to grow faster. These findings suggest that a more competitive and integrated financial market induced by financial deregulation is indeed able to improve banks’ productivity.     

城市交通拥挤原因与疏导策略

随着城市机动车数量的急剧发展,交通拥挤已经成为目前城市交通的主要问题。本文从宏观、微观两个层面分析拥挤成因以及拥挤的不利影响,找出城市交通拥挤的症结所在。通过分析常发性交通拥挤与偶发性交通拥挤基本特性,制定相应的交通拥挤控制和疏导策略,并提出了交通拥挤治理的基本原则。     

FDI引入对中国就业效应分析

伴随着我国开放政策的深化和加入WTO,FDI的就业效应日趋成为学者们的重要研究课题。本文通过对FDI较为系统地分析,认识到FDI的就业效应更应该是一种间接和长远的效应,且其具有空间性和时间性特征。因此本文从FDI的关联性和长远的动态特征等方面对其就业效应进行分析。     

Should we worry about the decline of the public corporation? A brief survey of the economics and external effects of the stock market

In recent years, the number of listed companies has been declining in many countries across the world. This paper provides a selective survey of the literature on the real economic effects of the stock market to assess the potential effects of this decline and determine whether it is likely to continue. The leading economic role of the stock market’s primary market, in which firms raise capital by issuing new shares, is to help growing firms secure financing. We discuss providing and certifying information, coordinating investors, and easing the redeployment of capital as the means through which capital allocation can be efficiently achieved. The main economic roles of the stock market’s secondary market, the trade in existing shares, is to provide liquidity to shareholders, to aid in price discovery and to provide diversification opportunities. Positive external effects from an active stock market may arise for consumers, labor and private firms due to increased corporate investment, more socially responsible business strategies and a more positive business climate. Negative external effects on capital allocation and productivity can arise from short-termism, market mispricing, and increased cross-ownership. Local stock markets can spur innovation and foreign direct investment (FDI) and reduce the risk of early cross-border acquisitions. Given the myriad of useful economic functions the stock market performs, a future entirely absent of public companies is difficult to imagine and the decline is therefore likely at some point to come to an end. Whether we need to worry about the decline depends on the relative importance of the positive and negative external effects, a topic we feel warrants more research.     

THE IMPACT OF THE EU EMISSIONS TRADING SYSTEM ON COMPETITIVENESS AND CARBON LEAKAGE: THE ECONOMETRIC EVIDENCE

This paper carefully surveys the econometric literature that tests for competitiveness effects and related carbon leakage caused by the EU Emissions Trading System (EU ETS). The results of this literature tell us that to date there is no evidence of the EU ETS having had widespread negative or positive effects on the competitiveness of regulated firms, nor is there evidence of significant carbon leakage. However, the paper also identifies three important caveats to this general conclusion. Firstly, the evidence we have still largely refers to the first two trading periods, namely Phases I (2005–2007) and II (2008–2012). Secondly, some heterogeneity of estimated effects is observed, but patterns, notably sectoral patterns, hardly emerge. Thirdly, very little explored is whether the EU ETS has had long-term effects on the economy via investment leakage or firm dynamics. Further empirical studies investigating these long-term effects are particularly desirable.     

UNIVERSAL PRESCHOOL PROGRAMS AND LONG-TERM CHILD OUTCOMES: A SYSTEMATIC REVIEW

What are the long-term effects of universal preschool programs on child outcomes? We review 26 studies using natural experiments to estimate the effects of universal preschool programs for children aged 0–6 years on child outcomes measured from third grade to adulthood. Studies comparing universal preschool with a mix of parental, family, and private modes of care show mixed effects on test scores and on measures related to health, well-being, and behavior. All estimates for outcomes related to adequate primary and secondary school progression, years of schooling, highest degree completed, employment, and earnings indicate beneficial average effects of universal preschool programs. Three of the included studies calculate benefits-to-costs ratios and find ratios clearly above one. Universal preschool tends to be more beneficial for children with low socioeconomic status and there are not consistently different effects for boys or girls. Only three studies compare two alternative types of universal preschool programs in terms of long-term outcomes.
