The optimal portfolio for the two-pillar mandatory pension system: the case of Poland

In the recent decade, there has been observed across the Central and Eastern European states the regulatory trend towards the increase of the non-financial (first) pension pillar size at the expense of the financial (second) pillar. It tends to question the consequences of this shift for the future retirement benefits. Applying the portfolio approach we address this issue by running a series of simulations to find out how to allocate pension contributions between both pillars in an optimal way. Our study contributes to the existing literature as follows. First, we do not perform the assessment of the predetermined regulatory solutions, but we look for an optimal one. Moreover, we allow our optimal rule to be time-varying, if necessary, which would be a true novelty in this research area. Second, we do not base our estimates on historical trends; rather, we apply the long-term economy’s projection to account for the society’s ageing impact, which is a crucially important factor for the solvency of the pension system. Adapting some of the simulation assumptions to fit the Polish case, our results confirm that current regulations underestimate the role of the capital pillar and the optimal allocation between both pillars should be time-varying.     

控制权性质影响税收敏感性吗?——基于企业劳动力需求的检验

西方学者研究表明企业所得税是劳动力需求的重要影响因素,这一理论在中国是否适用?中国大部分上市公司为国有控股企业,这一特殊的制度背景是否会影响企业所得税与劳动力需求的关系?本文基于2007年企业所得税改革这一外生政策变化,在检验西方企业所得税与劳动力需求关系的理论在中国是否适用的基础上,就不同控制权的性质是否会影响企业劳动力需求的税收敏感性进行了检验。研究发现企业所得税税率降低和"就业税盾"增加提高了企业劳动力需求,但这种税率和"就业税盾"的变化对国有控股企业劳动力需求变化的影响要显著小于非国有控股企业。这表明税收是影响企业劳动力需求的重要因素,但国有控制权使得这种税收敏感性变弱。本文的研究结果不仅丰富了相关领域的国际学术文献,而且对我国就业政策的制定具有政策含义。     

Classical meets modern in the IDEA protocol for structured expert judgement

Expert judgement is pervasive in all forms of risk analysis, yet the development of tools to deal with such judgements in a repeatable and transparent fashion is relatively recent. This work outlines new findings related to an approach to expert elicitation termed the IDEA protocol. IDEA combines psychologically robust interactions among experts with mathematical aggregation of individual estimates. In particular, this research explores whether communication among experts adversely effects the reliability of group estimates. Using data from estimates of the outcomes of geopolitical events, we find that loss of independence is relatively modest and it is compensated by improvements in group accuracy.     

Structural Changes in China’s Import Market: A Comparison with Korea’s Exports to China

The article examines the structural changes of China’s import market for domestic demand and the corresponding structural changes of Korea’s exports to China for Chinese domestic demand. Using 8-digit HS code data covering the period 2006–2014 and analyzing the processing steps as well as by industry, this study reveals that while the share of ordinary trade in total China’s imports has increased rapidly, the share of processing trade has decreased continuously since the mid-2000s. The article also shows that Korea’s exports to China is still processing trade-oriented. The slowdown of Korea’s exports to China is because of the concentration on processing trade, intermediate goods, electronics and chemistry.

主承销商的买入推荐可信吗?——来自中国的证据和启示

以2004-2009年的A股IPO公司为样本,我们探讨主承销商分析师买入推荐的可信性问题。我们的研究表明,在市场表现较差时,主承销商分析师倾向于给出买入推荐。此外,相对于主承销商,市场更相信其他券商分析师给出的买入推荐。我们还发现,其他券商分析师也能够识别主承销商买入推荐所包含的乐观性偏差。我们的这一结论为主承销商分析师所面临的利益冲突问题提供了直接证据,不仅有助于投资者更好地进行投资决策,也有利于监管当局对证券分析师行业对症下药,从而更好地保护投资者利益。     

中国参与全球生产链的技术溢出效应分析

全球生产链背景下的中国进口和外资表现出两个典型化特征:一是全部进口中中间产品占比非常高;二是在华外资企业对进口依赖程度高并且具有很强的外向型特征。这些特征影响了进口和外资这两大渠道对中国企业的技术溢出效果。本文的实证研究发现,中间产品进口对内资企业没有产生理想的技术溢出,且拉大了外资、内资企业间的技术差距;外资企业对进口依赖度越小,其技术溢出效果越好,且进口依赖度和外资数量的技术溢出效果存在正的交互作用;外资企业出口导向特征越明显,技术溢出效果越差。     

试析学生会的组织结构特征:松散联结基础上的牢固联结性

学生会作为学校党委、团委领导下的正式组织在高校的学生工作中发挥不可忽视的作用。学生会在组织结构上存在松散联结的基础,但它通过内部横、纵向的管理和外部行政系统的管理将其纳入到学校的行政体系中,并通过组织结构与组织成员理性化的结合,实现学生会组织结构的牢固联结,从而促使学生会各项工作的有序开展及目标实现。
