中国城镇居民的劳动供给行为——倒S型劳动供给曲线在中国城镇劳动力市场上的实证检验

依据2002年中国家庭收入项目(CHIP)数据,本文应用微观经济计量方法估计了城镇居民的就业方程和工作时间方程。研究结果表明,随着教育年限的增加,个体就业概率不断增加;随着家庭其他收入的增加,个体就业倾向逐渐降低,工作时间逐渐减少;随着家庭人口数的增加,就业个体的工作时间逐渐增加。低收入群体女性和男性工作时间的工资弹性分别为-0.3237和-0.3167,而女性中高收入群体工作时间的工资弹性为0.1429,说明倒S型劳动供给曲线在2002年中国城镇劳动力市场是存在的。因此,政府部门应结合经济发展水平适时地提高最低工资标准,完善社会保障制度,同时加大对低收入群体教育和培训投入力度,促进低收入群体社会福利水平的改善。     

Effect of religious priming in prosocial and destructive behaviour

In this paper, we study the behavioural impact of religious priming by showing participants religious words in a scrambled sentence task before a dictator game and a joy‐of‐destruction game. We also elicited data on individual religiosity and religious affiliation using a questionnaire. Priming religious words significantly increased prosocial behaviour in the dictator game, and the effect was especially striking among those reporting no religion, atheists and agnostics. The religious prime has no significant effect in mitigating destructive behaviour or own expectations of the other's destruction choice, but both destructive behaviour and expectations correlate positively with the multi‐dimensional religiosity measure.     

计及外部性的储能系统价值测算及经济性评估

以应用在电力系统中的电储能系统为研究对象,以外部性理论为基础,构建了计及外部性的储能系统经济性测算模型,并以储能系统接入光伏电站为例,采用贴现现金流分析方法,预估储能投资成本和收益,分别从投资者角度和社会整体效益角度,来研究储能系统应用在可再生能源发电侧的经济性,并进行了盈亏平衡分析。通过盈亏平衡曲线分析了储能盈亏平衡情景,经济性分析结果显示储能系统的外部性收益占年收益比例较大。

Volatility forecasting: long memory,regime switching and heteroscedasticity

In this article, we account for the first time for long memory, regime switching and the conditional time-varying volatility of volatility (heteroscedasticity) to model and forecast market volatility using the heterogeneous autoregressive model of realized volatility (HAR-RV) and its extensions. We present several interesting and notable findings. First, existing models exhibit significant nonlinearity and clustering, which provide empirical evidence on the benefit of introducing regime switching and heteroscedasticity. Second, out-of-sample results indicate that combining regime switching and heteroscedasticity can substantially improve predictive power from a statistical viewpoint. More specifically, our proposed models generally exhibit higher forecasting accuracy. Third, these results are widely consistent across a variety of robustness tests such as different forecasting windows, forecasting models, realized measures, and stock markets. Consequently, this study sheds new light on forecasting future volatility.     

Synergizing independent and cooperative R&D activities: the effects of organisational slack and absorptive capacity

Firms undertaking independent and cooperative research and development (R&D) activities simultaneously often have difficulties to realise their synergistic effects. This study contends that such difficulties are caused by tensions between two types of R&D activities in terms of resource competition and knowledge leakage. Moreover, organisational slack and absorptive capacity may affect these tensions and thereby play important role in synergizing independent and cooperative R&D activities. Based on a survey data of 286 firms, this study finds that such two types of R&D activities jointly have a negative impact on firm performance. Furthermore, organisational slack aids in synergizing them, while absorptive capacity has an adverse impact. These findings enrich our knowledge on the interrelation of independent and cooperative R&D activities and shed light on how firms can synergize them.

交通基础设施与制造业区位选择的空间计量经济学分析

本文将交通基础设施存量引入到制造业的区位选择模型中,对2006年制造业在中国大陆31个省域的投资强度及其影响因素进行空间计量经济学分析.结果显示,我国制造业与交通基础设施存量都存在局部集聚,且二者在空间分布上表现出很强的一致性,交通基础设施是影响我国制造企业区位选择的重要因素.     

府谷治污怪招的理论分析

地方保护主义严重存在于我国环境保护过程中，造成这一状况的原因主要是环境保护法律制度不健全、环境保护机构设置不科学和国民的环境保护意识不强。本文就此指出了改变现状的措施：强化国民环境意识、完善环境立法和改革环境保护体制。
