高质量发展下中国产业转型升级方向研究

产业不断转型升级是实现经济高质量发展的关键，从数量和质量两个维度可以总结出其具体路径。选取1985-2017年中国年度数据和1960-2017年美国年度数据，运用向量自回归模型对广义和狭义产业结构以及经济增长间的动态关系进行分析。结果表明，中美之间产业转型升级对经济发展的影响存在差异，据此可以得出高质量发展下中国产业转型升级方向，即拓展并细化产业转型升级维度;注重不同产业间的配比，尤其是生产性服务业和制造业配比;重视并确立制造业的根本地位;提升我国经济外向型程度。     

金融服务开放与制造业企业出口产品质量:影响机制与经验证据

文章从理论上分析了金融服务开放影响制造业企业出口产品质量提升的动态演变过程，并利用2004-2013年中国金融服务进出口和中国工业企业数据对理论推演进行验证。结果表明：金融服务开放显著促进了制造业出口产品质量升级，且金融服务引进来对制造业企业出口产品质量提升的作用略大于金融服务走出去所产生的作用；从不同贸易方式、不同衡量指标、不同企业所有制等方面对此进行检验均证实了金融服务开放对制造业出口产品质量升级的正向作用；影响机制检验和扩展分析显示，创新效应、金融服务"引进来"对"走出去"的推动、垂直专业化效应和本地吸收效应影响着金融开放对企业出口产品质量升级的作用。文章的研究发现有助于为进一步扩大金融服务开放来推动制造业高质量发展提供有价值的政策依据。     

The poor outside the lamplight: on the prevalence of poverty among population groups not included in household surveys

Poverty rate calculations are often based on household surveys that exclude some of the groups most vulnerable to poverty such as the homeless. This paper documents the nature of the excluded groups and the quantitative importance of their omission for the Czech Republic. Our study combines European Union Statistics on Income and Living Conditions data for 2011 with information from the 2011 Population Census. Our preferred estimate indicates an increase in the poverty rate by almost one percentage point. The paper contributes to accurately identifying the most vulnerable members of the society, which is essential for setting effective social policies.     

Dynamic Cost Inefficiency of the European Union Meat Processing Firms

We apply dynamic data envelopment analysis (DEA) to estimate dynamic cost inefficiency for a sample of European Union (EU) large meat processing firms over the period 2005–2012 and decompose this into the contributions of technical and allocative inefficiency. The estimation of dynamic inefficiencies controls for adjustment costs associated with firms’ investments. We further contribute by measuring dynamic cost inefficiencies and their components with regard to own region group (managerial inefficiencies) and the gap between the pooled frontier and the region-specific frontier (programme inefficiencies). Results show that technical inefficiency tends to be the largest component of cost inefficiency when both conducting the analysis for the EU as a whole and estimating a region-specific frontier. Results suggest significant differences in cost, technical, and allocative inefficiencies between meat processing firms in eastern, western and southern EU countries. We also find that the gaps between the pooled and region-specific frontiers tend to be small to negligible, which suggests that the main source of pooled inefficiencies are shortcomings in managerial practices rather than differences in region-specific conditions.     

Error analysis of finite difference and Markov chain approximations for option pricing

Mijatovi? and Pistorius proposed an efficient Markov chain approximation method for pricing European and barrier options in general one‐dimensional Markovian models. However, sharp convergence rates of this method for realistic financial payoffs, which are nonsmooth, are rarely available. In this paper, we solve this problem for general one‐dimensional diffusion models, which play a fundamental role in financial applications. For such models, the Markov chain approximation method is equivalent to the method of lines using the central difference. Our analysis is based on the spectral representation of the exact solution and the approximate solution. By establishing the convergence rate for the eigenvalues and the eigenfunctions, we obtain sharp convergence rates for the transition density and the price of options with nonsmooth payoffs. In particular, we show that for call‐/put‐type payoffs, convergence is second order, while for digital‐type payoffs, convergence is generally only first order. Furthermore, we provide theoretical justification for two well‐known smoothing techniques that can restore second‐order convergence for digital‐type payoffs and explain oscillations observed in the convergence for options with nonsmooth payoffs. As an extension, we also establish sharp convergence rates for European options for a rich class of Markovian jump models constructed from diffusions via subordination. The theoretical estimates are confirmed using numerical examples.     

海归与企业出口行为:来自中国的微观证据

海归能否促进母国企业的出口？目前国内还尚未有文献专门对此进行研究。本文使用工业企业微观数据、海关贸易数据以及中国上市公司治理结构研究数据库的合并样本,系统评估了海归对企业出口行为的影响。研究发现,海归对企业出口产生了积极作用,并且上述正向的“出口拉动”效应在样本期内具有持续性而且是逐年递增的。进一步,我们考察了地区制度环境的重要性,发现良好的地区制度环境有利于强化海归对企业出口的促进效应。最后,行业出口质量的动态分解表明,资源再配置效应对行业出口质量提高的贡献高达54%,其在海归促进行业出口质量提高中发挥了关键作用。本文从微观层面证实了海归“出口拉动”效应的存在,对我国有效挖掘海归在提升企业出口竞争力方面的优势和潜力具有政策参考价值。     

Chair-CEO generation gap and bank risk-taking

Poor bank governance has disastrous consequences for economies as the 2007–2009 financial crisis has shown. In the aftermath, board diversity is identified as an effective mechanism to enhance bank governance. Diversity, creating cognitive conflict between board members, is expected to enhance board's independence of thought to better perform monitoring and advising functions. Age is a key demographic measure and age dissimilarity between the chair and the CEO in non-financial firms leads to better economic outcomes (Goergen, Limbach, & Scholz, 2015). In this paper, we examine whether chair-CEO age dissimilarity can mitigate banks' excessive risk-taking behaviour. Using a unique sample of 100 listed banks in Europe between 2005 and 2014, we find that age difference between the chair and the CEO reduces bank risk-taking. A chair-CEO generational gap –defined as a minimum of 20 years' age difference– has a larger impact in reducing risk-taking.     

“强监督”还是“搭便车”：自然人大股东如何影响企业专利质量

通过构建改进的知识宽度法测算企业专利质量，并以2007—2016年中国沪深A股上市公司为样本，分析自然人大股东对企业专利质量的影响以及在不同类型企业中其作用的差异性。结果表明，作为“强力监督者”，自然人大股东能够促进企业专利质量提高。但因为其角色由“强监督”转变为“搭便车”，故这种促进作用在国有企业和具有政治关联的企业中并不存在。进一步研究表明，促进作用是通过加强对经理人和研发人员的监督，减少其控制权下投机性创新策略，提升其工作努力程度实现的。研究结论为促进国有企业与民营企业创新能力提升提供相应的政策启示。     

The contribution of granular and fundamental comparative advantage to European Union countries' export specialisation

This paper analyses the contribution of fundamental comparative advantage (a country-specific component) and granular comparative advantage (a firm-specific component) to European Union countries' export specialisation. We find that, on average, granular comparative advantage may explain export specialisation in 29% of industries, which account for 47% of total exports. We also show that 60% of the variation in export specialisation across countries and industries may be explained by granular comparative advantage. These results highlight that some outstanding firms may play a very important role in explaining European Union countries' export specialisation.     

会计信息价值相关性研究:国外文献评述

全面梳理会计信息价值相关性研究文献,系统评价盈余公告反应研究和会计信息估值研究成果。得出结论:现有盈余公告反应研究的主要观点是,影响盈余公告向市场传递未预期盈余信息大小的主要因素为信息披露前的环境特征,影响盈余信息含量的主要因素为未预期盈余持续性;现有关于会计信息估值的研究主要是以财务比率对未来盈利的预测能力的质量驱动研究和主要基于具体的估值模型的价值驱动研究。未来的研究应在特殊情景、估值模型的拓展以及更新研究方法方面作出努力。
