Foreign direct investment subsidy in a dynamic stochastic general equilibrium model with heterogeneous firms

This study analyzes the macroeconomic impacts of subsidies to attract multinational corporations when firms are determining whether to enter or how to serve foreign markets. We show that a small FDI subsidy scheme induces consumption gains and delivers short‐term welfare improvement for the FDI host country if firms differ in productivity. However, the subsidy generates a new problem and results in the wealth reallocation effect, leading to welfare deterioration for the host country in the long run. Moreover, we find that a subsidy program induces a welfare improvement for the host country if it is offered to all domestic producers instead of foreign producers only in the host country.

“免疫系统”理论视野下的国家审计

"免疫系统"理论的形成与提出是审计理论的创新,在今后相当长的一段时期内具有理论研究价值和现实指导意义.在"免疫系统"理论新视野下,国家审计应在借鉴免疫系‘统的自发性和自适应性的基础上,确保其独立性和强制性,完善审计机制;发挥防御、自稳、监督职能和防护性、建设性、调控性等作用,维护国家安全.作为经济社会运行中的"免疫系统",国家审计的内在机理是及时发现问题、依法处理问题、充分利用成果、依法报告工作.而不断增强并充分发挥国家审计的"免疫系统"功能的措施有:积极探索务实高效和充分保障审计独立性的体制机制;努力完善国家审计联系制度和审计结果公开制度;持续改进各部门的协调机制及国家审计的创新机制;大力加强基础建设,夯实可持续发展的根基.     

Extending the link between entrepreneurial self-efficacy and intention: a moderated mediation model

This study extended the research on the relationship between entrepreneurial self-efficacy and intention by developing a moderated mediation model. This model posits that the link between entrepreneurial self-efficacy and intention is mediated by attitudes toward entrepreneurship and planned entrepreneurial control, and that these mediation processes are further moderated by subjective norms. Based on a sample of 308 valid responses, regression analysis yielded two noteworthy results. First, entrepreneurial self-efficacy positively affects intention through attitudes toward entrepreneurship and planned entrepreneurial control. Second, the direct effect of entrepreneurial self-efficacy on intention decreases as subjective norms increase. By contrast, the indirect intention effects of entrepreneurial self-efficacy through attitudes toward entrepreneurship and planned entrepreneurial control increase as subjective norms increase. In addition, the results indicated that subjective norms positively affect entrepreneurial intention. These findings indicated that the model advances the use of the theory of planned behavior and can be used to define a person as an entrepreneur.

Sequential estimate for linear regression models with uncertain number of effective variables

As a result of novel data collection technologies, it is now common to encounter data in which the number of explanatory variables collected is large, while the number of variables that actually contribute to the model remains small. Thus, a method that can identify those variables with impact on the model without inferring other noneffective ones will make analysis much more efficient. Many methods are proposed to resolve the model selection problems under such circumstances, however, it is still unknown how large a sample size is sufficient to identify those “effective” variables. In this paper, we apply sequential sampling method so that the effective variables can be identified efficiently, and the sampling is stopped as soon as the “effective” variables are identified and their corresponding regression coefficients are estimated with satisfactory accuracy, which is new to sequential estimation. Both fixed and adaptive designs are considered. The asymptotic properties of estimates of the number of effective variables and their coefficients are established, and the proposed sequential estimation procedure is shown to be asymptotically optimal. Simulation studies are conducted to illustrate the performance of the proposed estimation method, and a diabetes data set is used as an example.     

Do insurance activities enhance the performance of financial services holding companies?

Stiroh and Rumble (2006) and Yeager et al. (2007) have argued that extension of banks into nonbanking activities produces no diversification benefits for financial services holding companies (FSHCs) eligible to consolidate banking and insurance products. We investigate the effect of aggregate nonbank activities, as well as two main areas of insurance business, namely agency and underwriting enterprise, on the risk-adjusted performance of FSHCs. Our sample includes a quarterly panel data of FSHCs over the period 2003–2011. We find that the effect of FSHCs’ entry into agency insurance activities on their risk-adjusted returns is dependent on their size; it is positive for FSHCs in the top quartile of our sample (assets greater than $4.495 billions), but negative for smaller and mid-size FSHCs. The effect of underwriting insurance activities on risk-adjusted returns is generally negative or statistically insignificant, except for some of the largest-size firms.     

户籍制度扭曲及放松对经济的影响:理论与实证

户籍制度是我国劳动力流动的主要障碍.那么,当前我国的户籍扭曲程度几何?户籍制度放松对经济又会有怎样的影响?对这些问题的回答将有助于政府评估户籍制度改革的空间和经济效益.文章在Hansen和Prescott(2002)的两部门劳动力流动模型基础上,将工人分为农业和非农户口,引入户籍扭曲因子,构建两部门两类工人的户籍扭曲模型;然后,使用1984?2013年宏观经济数据度量户籍扭曲程度,并对2013年我国户籍制度逐渐放松过程中经济变量的变化进行模拟;最后,文章建立了包含农业与非农和本地与外地户籍差异的省份异质性户籍扭曲模型.研究表明:(1)经济和户籍制度改革的不同步导致了1984?2013年我国户籍扭曲程度呈现倒U形变化,且相较于韩国尚有较大的改善空间;(2)以韩国为参照,若2013年我国户籍制度完全放开,经济达到均衡时,农业部门和非农部门的就业人数将分别下降58.83%和上升26.92%,工资率将分别上升19.44%和下降6.77%,社会增加值将增长15.33%,这说明社会经济效率将得到提升,贫富差距将缩小.文章丰富和完善了户籍扭曲的理论模型,从减少劳动力流动摩擦的视角为政府制定相关政策提供了参考.     

中资银行海外并购后的整合问题研究

海外并购作为公认的能够快速调整海外资产收入结构和利润结构的手段,如今已经获得越来越多中资银行的肯定。近几年来,由于全球经济危机所导致的海外并购成本的降低更为中资银行提供了绝佳的动作机会。然而,在跨越了资金和政策等方面的并购鸿沟后,并购后的整合问题开始逐渐浮出水面。本文在总结分析我国银行国外并购整合的现有问题基础上,分三个方面对于中资银行海外并购后的整合提出具体的指导建议。     

非标准工作与体面劳动:数据化带来的劳动问题与政府对策

数据化促进了经济发展,也造成了传统雇佣模式的变化.本文以互联网平台为例,从国际视角分析了数据化带来的劳动者权益保障问题,并简要概括了国际劳工组织与发达国家解决这些问题的对策.笔者提出,互联网平台从业者大部分从事的是非标准工作,这类工作存在体面劳动方面的诸多缺陷.笔者认为,在传统雇佣关系发生变化之后,无需再用传统的定义和标准去研讨非标准工作从业者是否具有“雇员”的身份,而应当将这些通过劳动获得报酬的从业者视为“劳动者”.笔者指出,政府应当尽其所能,制定和修改劳动政策,为他们提供底线型的基本保障,帮助他们实现体面劳动.
