Marrying personality and job resources and their effect on engagement via critical psychological states

This study examined the process by which individuals become engaged with their jobs by integrating seminal engagement theory. More specifically, we suggest that an individual factor (i.e. autotelic personality) and two contextual factors (i.e. feedback environment, job autonomy) interact to predict work engagement through three critical psychological states – namely availability, meaningfulness, and safety. This moderated mediation framework was tested using a cross section of the US population (n = 284); data were collected at two points in time with 3 months in between. Availability and meaningfulness mediated the relationship between autotelic personality and work engagement. Autotelic personality’s indirect effect on work engagement through meaningfulness and safety was conditional such that the nature of feedback environment’s effect depended on job autonomy level. Theory and practice implications are discussed.     

基于生理反馈的城市滨河步道对青年人压力缓解的研究

现今社会竞争日益激烈,青年人的精神压力不断增加。现有研究表明,自然环境对人们的身心健康有着积极的影响,但目前与人们生活密切相关的城市中的自然环境对健康的促进作用研究较为缺乏。通过采集参与者在2段差异性高的滨河实景环境中行走的生理信号和眼动数据,探究不同滨河步道景观下青年人的压力缓解情况和视觉特征。研究结果表明：1)以SDNN、RMSSD和Lorenz散点图为代表的心率变异性特征(HRV)在不同区段的滨河步道下呈现明显差异,绿化程度高的场景对压力的缓解作用更强;2)不同场景下的视线特征与压力缓解有一定的关联性,行人的视线多偏向于步道滨水侧开敞度高的空间,经过绿化程度高或有休憩空间的滨河步道场景时,行人的视线更分散,压力缓解效果更佳。将缓解压力作为滨河步道的景观功能之一,通过主动干预有针对性地进行滨河景观类型与植物种植的改造,以期达到更好的滨河步道环境提升效果。     

Intercountry feedback and spillover effects within the international supply and use framework: a Bayesian perspective*

This paper proposes a new framework for the estimation of product-level global and interregional feedback and spillover (FS) factor multipliers. The framework is directly based on interregional supply and use tables (SUTs) that could be rectangular and gives a possibility of taking account of the inherent input–output data uncertainty problems. A Bayesian econometric approach is applied to the framework using the first version of international SUTs in the World Input–Output Database. The obtained estimates of the global and intercountry FS output effects are discussed and presented at the world, country and product levels for the period of 1995–2009.

基金股票仓位与A股市场走势相关性研究

在划分股市牛熊周期的基础上,采用VECM模型和VAR方法对基金股票仓位变动与股票市场走势之间关系进行研究,结果表明基金股票仓位与股票市场收益率二者之间的关系存在着显著性和非稳定性,即基金作为主要机构投资者对股票市场的走势具有重要影响作用,而在股市的各个不同阶段,基金持仓比例的波动与A股指数收益率二者之间的关系各不相同。     

合格境外机构投资者投资行为的实证分析

根据QFII每季度公布的投资组合数据,对其交易行为进行研究,结果发现:QFII存在正向反馈策略和"羊群行为",而已有的研究证明,正向反馈策略和"羊群行为"不利于股票市场稳定。因此,要注意加强对QFII投资的监管,尤其是QFII信息披露的监管。

Monetary policy rules with PID control features: evidence from the UK,USA and EU

ABSTRACT

This paper considers the extent to which the monetary policy operations of three major central banks can be regarded as an application of Proportional-Integral-Derivative (PID) control rules. The paper outlines the general PID framework and estimates a series of dynamic models to identify how interest rate policy adjustments are affected by the rate of inflation and the level of macroeconomic activity. The paper examines data for the UK, the USA and the Eurozone. The results suggest that the PID rules can provide a useful theoretical and empirical framework for estimating central bank responses to the inflation and macroeconomic activity variables by improving the explanatory power of the Taylor rule model and determining the effect of the parameters.     

正向反馈申购者、市盈率管制与新股发行定价

传统的新股发行定价偏低观点受到了一些定价偏高实证现象的质疑,且难以解释我国长期实行的发行市盈率管制政策。本文在原有信息不对称理论的基础上,从正向反馈的非理性角度研究发行定价,进而分析市盈率管制政策的作用,并实证检验。研究认为,新股发行市场中存在着大量的正向反馈申购者,他们受近期新股上市表现激发而参与申购,这种噪声需求的存在使得新股即使被高估也仍然能够成功发行。发行人和承销商意识到这种噪声需求的存在,为了使其利润最大化,他们会抬高发行定价,而机构投资者在近期新股上市表现较好的情况下也易于高估新股,因此也能接受较高的询价价格。实证结果验证了正向反馈申购者对发行定价的这一正向影响,并且发现市盈率管制政策能够对此起到一定的抑制作用。     

A dynamic model of R&D competition

This study considers a dynamic model of R&D competition in a situation of no uncertainty with identical firms in a perfect foresight. We are going to find out about the effects of firms' absorptive capacity on R&D strategies in the presence of technological spillovers. The conditions for the existence and uniqueness of a feedback–Nash equilibrium on firms' R&D expense will be also discussed. Numerical simulations will show as the introduction of the absorptive capacity reduces the impact of spillovers degree on firms' R&D strategies.
