煤炭资源型城市聚集经济与城市化水平研究

运用可变权系数综合评价模型对2002年中国煤炭资源型城市城市化水平进行测度;基于1999～2002年度煤炭城市面板数据,应用随机效应模型估计煤炭城市聚集经济水平;结果表明,我国煤炭城市城市空间经济结构效率和其城市化水平并不具有正相关性,许多城市化水平相对较高的煤炭城市的聚集经济较差,并没有显示出城市化经济的优势.     

债务融资的治理效应:理论分析与实证检验

首先就西方财务学关于债务治理效应的理论进行了综述，然后采用中国上市公司的经验数据，对债务融资比例与企业绩效指标的关系进行了检验，得出了债务治理效应不佳的结论。这一结论似乎与西方财务学对债务治理效应的主流分析不符。通过分析其中的现实原因，就如何改善中国企业的债务治理效应，提出了相应的政策建议。     

一项关于价格水平决定的财政理论的实证研究

本文遵循Sala的五变量VAR方法发现,在绝大部分时间里,实际利率对一个标准差的实际税收正向冲击的反应为正,这就为价格水平决定的财政理论提供了来自中国的经验证据的支持。除此之外,与很多学者一样,本文还发现了实际税收冲击的非凯恩斯效应。

中国资本市场的中长期动量效应和反转效应——基于Fama和French三因素模型的进一步研究

基于国内外学者对于中国股票市场的动量效应和反转效应的研究,利用1994~2004年中国股票市场的经验数据,借助于Fama和French的三因素模型,对中国股市的动量和反转效应进行解释。研究结果表明,Fama和French三因素模型的解释力度不大。     

“一带一路”倡议下我国重点省市物流绩效评价研究

物流建设是“一带一路”倡议发展的重点。通过物流设施建设、拓展物流业发展的新方向,促进地区融合、加强多边贸易、加速互联互通,是我国现行经济格局下“一带一路”重点建设省市物流发展的新走向。文章从政府行为、社会效益、服务水平三个维度构建了包含地区经济、物流政策、数字物流等14个指标的物流绩效评价指标体系,利用数据包络法对我国“一带一路”重点建设省市的物流绩效进行评价,发现我国物流业发展存在地区差异大、服务水平过低的现象。结合地方政府的政策解读,发现我国地区物流绩效水平呈现出一定的政策相关性,可通过合理的政策引导促进地区物流业的发展。     

Who are better monitors? Comparing styles of supervisory and independent directors

This paper compares the unobservable style effect between independent directors and supervisory directors on firm performance. Utilizing the unique Chinese board system with both independent and supervisory directors and a large panel data of 2,240 public firms from 2003 to 2017, this paper finds that both supervisory and independent style is crucial in determining variations of firm performance. The effects of both independent and supervisory director style are less significant when the “type II” agency problem is more severe in a firm. Moreover, outside independent director style is more effective when information costs are low or when firms need more outside resources, while inside supervisor director style is more effective when there are no major internal changes. Finally, the results also suggest that increasing qualified supervisor representations are beneficial to firms.     

Convenient estimators for the panel probit model: Further results

Bertschek and Lechner (1998) propose several variants of a GMM estimator based on the period specific regression functions for the panel probit model. The analysis is motivated by the complexity of maximum likelihood estimation and the possibly excessive amount of time involved in maximum simulated likelihood estimation. But, for applications of the size considered in their study, full likelihood estimation is actually straightforward, and resort to GMM estimation for convenience is unnecessary. In this note, we reconsider maximum likelihood based estimation of their panel probit model then examine some extensions which can exploit the heterogeneity contained in their panel data set. Empirical results are obtained using the data set employed in the earlier study. Helpful comments and suggestions by Irene Bertschek and Michael Lechner are gratefully acknowledged. This paper has also benefited from comments by two anonymous referees and from seminar participants at the Center for Health Economics at the University of York.

Altruism and the Economic Values of Environmental and Social Policies

Altruism is a type of non-use value which can have different definitions depending on the type of goods entering the utility function of the altruists and their expectations about the contributions of others. The purpose of this paper is to measure the trade-offs between different types of altruist values originating from social and environmental policies. Environmental policies are concerned with reducing health effects from a power plant while social policies involve both the attainment of public facilities for education and leisure and an increase in the income of the affected population. The empirical application utilizes a choice experiment technique which allows for valuation of multiple goods. Health effects are decomposed into the values of the risk of becoming ill, the duration of the episodes and the limitations imposed by illness. Altruist values are elicited from a population that is not affected by pollution. Results show that altruism is significant for policies directed to reducing health effects and improving the income level of the affected population, whereas there is egoism for a policy aimed at improving public facilities in the polluted suburb. The value of altruism is significantly influenced by the expectations of net benefits to be received by the affected population.
