跨国公司在华R＆D投资溢出效应及特征分析

在研究跨国公司投资溢出效益方面．不少研究者较少考虑到R＆D投资本身的特殊性。本文在对跨国公司在华R＆D的实证分析的基础上，探讨R＆D投资的特征对溢出效应的影响。最后基于对实证结果和R＆D投资特征的分析，给出政策建议。     

Do Urban Neighborhoods Benefit from Homeowners? Evidence from Housing Prices

Homeownership is heavily subsidized in most countries. The adverse effects of this policy on economic efficiency and income distribution are well documented in the economics literature. The main argument in favor of subsidizing homeownership is that it creates positive externalities that offset these adverse effects. In this paper, we test whether homeowners create positive externalities that capitalize into housing prices in multi‐storey buildings. Using semi‐parametric hedonic regressions with and without instrumental variables, we find no evidence of positive externalities, although the results with instrumental variables are somewhat imprecise. This result is robust to several sensitivity checks and to a relaxation of the identification assumptions of our instrument using set identification.     

Infrastructure and Connectivity in India: Getting the Basics Right

Infrastructure helps in building productive capacity by bridging connectivity gaps, reducing distribution and trade costs, and facilitating the sharing of the benefits of growth with poorer groups and communities, among others. The evidence in this paper suggests the need for India to develop both hard as well as soft infrastructure for enhancing trade flows and growth. The existence of both aspects simultaneously will produce gains of a significantly higher order but one without the other is likely to be ineffective.     

我国研发强度增长态势预测分析

一些发达国家的发展经验表明,一国研发强度超过2%之后将保持低速增长。我国若重蹈别国的覆辙,将难以实现到2020年研发强度达2.5%的目标。从2006年至今的发展情况来看,我国的研发强度在突破2%之后或仍将保持较快增长,有望提前实现2.5%的目标。     

Does distance reflect more than transport costs?

We decompose the effect of distance on intercity retail price dispersion in US into transport and non-transport cost components. We find that distance contains more information than transport costs. Care should be taken in interpreting distance effect as transport costs only.     

Yield spreads,currency movements,and recession predictability for southern border economies in the United States

Prior research establishes that the spread between long- and short-term bond yields often provides valuable information for predicting business cycle downturns. This study examines the predictive capacity of the yield spread for the United States metropolitan economies situated along the border with Mexico. Because of the location of these urban economies and various economic ties linking them with twin cities across the border, the Mexico yield spread, and the real dollar/peso exchange rate are also employed as potential recession predictors. Results suggest that a flattening of the yield curve for either country tends to increase the probability of recessions in border economies. Furthermore, declines in the real value of the peso, which are typically associated with greater cross-border manufacturing activity, are found to reduce recession likelihoods in the metropolitan economies examined on the north side of the international boundary.     

R与当前大数据审计方法的比较研究

当前,审计人员进行数据分析时以Excel统计计算、SQL语句查询分析为主,而在大数据时代来临之际,这两种工具是否仍能继续作为大数据审计工具协助开展审计工作,本文将结合R语言,分别对其展开比较研究,为将来审计人员开展大数据审计提供基础的理论参考。     

对人民币国际化战略的思考

金融危机爆发后迫使美国政府推出两轮“量化宽松”的货币政策和激进的财政政策,造成世界范围的流动性过剩。美元一路下跌,人民币不断升值,使我国国际储备中的美元资产大幅缩水,并困扰着我国对外投资与贸易。如何规避汇率风险,打破困局成为许多专家学者担忧的问题。本文提出人民币国际化是解决问题的办法之一。     

Cournot竞争条件下异质企业最优创新技术获取策略分析

针对现实经济中企业创新技术获取问题,首先运用包括创新及产出阶段的博弈模型分析了合作创新模式;然后构建了包括创新、许可及产出阶段的博弈模型,并根据此模型重点分析了技术许可模式;最后通过比较分析得出企业最优的技术获取策略。研究表明：当创新为非显著水平且产品差异较小时,技术许可模式下通过两部制策略许可将是最优的;当创新为显著水平或产品差异较大时,合作创新模式下的合资企业或卡特尔是最优的。     

质量随机的研发竞赛模型与最优奖励

假设研发质量具有随机性,建立了研发竞赛的非合作博弈模型,分别探讨了完全信息和不完全信息条件下竞赛参与人与竞赛发起者的最优策略。研究发现：竞赛参与人的研发投入水平在完全信息和不完全信息条件下都随自身研发效率的降低而降低;研发参与人的类型信息不完全程度越高,参与人的均衡研发投入越低;在每一种信息类型组合下都存在着最优奖励使得竞赛发起者的期望收益最大。
