Capital Flight: China's Experience

We study the empirical determinants of China's capital flight. In addition to the covered interest differential, our empirical exercise includes a rather exhaustive list of macroeconomic variables and a few institutional factors. Overall, our regression exercise shows that China's capital flight is quite well explained by its own history and covered interest differentials. The other possible determinants offer relatively small additional explanatory power. It is also found that China's capital flight responds differently to the components of covered interest differentials and to the positive and negative components of these variables. The response pattern, however, depends on the choice of data frequency. The general impression is that the monthly results are more intuitive than the quarterly ones.     

1980-2006年东亚经济波动的原因——基于面板VAR的分析

东亚经济波动及其协同性的存在已得到学术界的认同,文章通过构建面板向量自回归模型,检验了6种冲击对东亚经济波动的影响,并考察了宏观经济各变量在面时冲击时的动态反应,以及汇率和通货膨胀对经济波动的传导作用.研究表明,国内的供给冲击、汇率冲击,国外的利率冲击、需求冲击都会对东亚经济波动产生较大影响,汇率是外部冲击的重要传导渠道,而通胀是内部冲击的重要传导渠道.随着东亚经济一体化进程的推进和金融市场不断开放,东亚各经济体对外部需求变动和世界利率变动所产生的冲击应予以重视.     

城市化水平对城乡收入差距影响的协整分析

改革开放以来,我国的经济发展水平有了很大提高,但城乡收入差距也随之扩大,不利于我国经济建设的稳定发展和构建和谐社会目标的实现.分析了我国城乡收入差距的现状,采用协整检验方法实证研究了城市化发展对城乡居民收入差距的影响,结果表明我国城市化发展扩大了城乡收入差距.在目前我国城市化进程中,应通过加快农村剩余劳动力的转移、大力开展农业技术培训、培育农民的市场意识、积极发展乡村的特色传统产业、鼓励富裕人员和知识分子回乡创业等政策缩小城乡居民收入差距.     

中国证券市场机构投资者与上市公司盈余管理关联性的研究

本研究从中国证券市场机构投资者与上市公司盈余管理之间关系这一视角出发,来说明机构投资者在公司治理中的作用,通过对相关理论的归纳和分析,构建了研究假设,在此基础上,利用中国上市公司数据,设计实证模型,对研究假设进行了论证.研究发现了在中国证券市场当机构投资者持股比例高时抑制盈余管理,机构持股比例低时加剧盈余管理,即倒U型的关系。研究应用截面数据分析、面板数据分析、单变量分析等方法,从2005年和2007年的数据验证出倒U型的拐点在机构持股6%,说明机构持股6%以后,在公司治理中发挥了抑制操纵盈余的盈余管理的积极作用。利用2004～2007年的数据,进一步的研究发现,随着近年机构投资者的发展和国家的政策导向,机构投资者对盈余管理的抑制作用越来越强,在公司治理中越来越显示出重要的作用。     

NONRESIDENT POSTSECONDARY ENROLLMENT GROWTH AND THE OUTCOMES OF IN‐STATE STUDENTS

We study the effects of exposure to nonresident students on the outcomes of undergraduate in‐state students during a period of high nonresident enrollment growth at the University of Missouri‐Columbia. Our models leverage within‐major, cross‐time variation in nonresident exposure for identification. We find no evidence that increased exposure to domestic nonresidents affects in‐state student outcomes and our null results are precisely estimated. We find evidence of modest negative impacts on in‐state students when their exposure to foreign students increases using our preferred specification. However, the identifying variation in exposure to foreign students in our data is limited and this result is not robust in all of our models. (JEL I23, I28, R23)     

科技服务渗透对制造业技术进步的影响

利用世界投入产出表计算制造业细分行业科技服务渗透指数,在此基础上实证分析科技服务渗透对制造业技术进步的影响。结果表明：科技服务渗透促进了制造业技术进步,但作用强度不尽如人意;科技服务业的创新贡献在不同要素密集型制造业差异较大;本土科技服务与进口科技服务对制造业创新绩效都具有显著激励作用,且前者比后者的创新促进效应更显著;科技服务对制造业的创新激励存在明显的本地化效应,本土科技服务与进口科技服务在制造业创新过程中存在互补促进作用,需要进一步强化本土科技服务对进口科技服务的消化吸收再利用能力。     

Rivaroxaban for non-valvular atrial fibrillation and venous thromboembolism in the Netherlands: a real-world data based cost-effectiveness analysis

Background: Non-vitamin K antagonist oral anticoagulants (NOACs) have been included in international guidelines as important alternatives to vitamin K antagonists (VKAs) for the treatment of venous thromboembolism (VTE) and stroke prevention in non-valvular atrial fibrillation (NVAF). Meanwhile, in the Netherlands, NOACs are widely used next to VKAs. The objective of this study is to estimate the cost-effectiveness of treatment with rivaroxaban compared to VKAs in NVAF and VTE patients in the Netherlands, using data from international prospective observational phase IV studies.

Methods: Two models were developed to represent NVAF and VTE patients, populated with patients from the XANTUS (NCT01606995) and XALIA (NCT01619007) international prospective observational studies. The 1-year cost-effectiveness of rivaroxaban use, compared to VKAs, was explored in a population consisting of NVAF and VTE patients (base case) as well as for four scenarios with sub-populations: NVAF patients only, VTE patients only, NVAF patients with unstable international normalized ratio (INR), and NVAF patients using an INR self-measuring device.

Results: In the base case, rivaroxaban saved €72,350 and gained 21 quality-adjusted life-years (QALYs) in a simulation of 2,000 patients over the use of VKAs. Ergo, rivaroxaban was dominant over VKAs. The probabilistic sensitivity analysis showed a probability of 85% for rivaroxaban being dominant and 100% at a willingness-to-pay threshold of €20,000/QALY. Rivaroxaban appeared to be dominant in all scenarios as well, except for the NVAF-patients-only scenario where the incremental cost-effectiveness ratio (ICER) was €157/QALY.

Conclusions: In patients with NVAF or VTE, rivaroxaban treatment is likely to be cost-effective and a potentially cost-saving alternative to VKA in the Netherlands.     

金融能力、金融决策与贫困

本文利用2013年中国家庭金融调查（CHFS）数据,通过因子分析法构建居民金融能力指数,运用Probit模型、工具变量法和中介效应模型实证分析了金融能力对贫困的影响以及金融能力、金融决策与贫困之间的作用机理。研究发现：（1）无论是绝对贫困还是相对贫困,金融能力能够显著抑制贫困的发生,且城镇地区相较农村地区更明显。（2）金融能力对贫困的影响既存在“抑制效应”,也存在“偏离效应”,两者之间呈现正“U”型关系。（3）经中介效应模型计算可知,在“抑制效应”下,金融能力可以通过改善金融决策来缓解居民贫困状况。具体而言,在三种不同的贫困状况衡量方式下,金融决策的中介效应占比分别为2542%,2296%和2160%。
