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.     

面向行为引导的高层次人才创业环境构建——突破我国高层次人才创业瓶颈期的政策设计

创业行动,尤其是高层次人才创业的规模和成功率,对提升我国整个社会的经济发展水平、经济结构调整优化、产业结构升级等具有不可替代的作用。创业过程可看成是一系列决策的制定、实施过程,并受创业企业高管团队结构的影响。该文针对我国各级政府在引导创业方面政策趋同、效果不佳,高层次人才创业遭遇瓶颈的现状,将创业绩效受损的原因区分为结构问题和环境问题两类,并提出针对性的政策建议。     

家长式领导效能的实证研究

就目前我国管理学界而言,管理理论的借鉴多于本土原创.因此,将中国企业一些优秀的管理方法抽象和总结,并与其他国家企业进行分享,家长式领导理论就是其一重要成果.家长式领导是我国台湾学者郑伯埙等人(2000)基于中华文化背景而提出的管理理论.企业管理行为因文化的不同会有不同的风格、内涵和效能.本研究在家长式三元领导管理的基础上,探讨家长式领导在我国企业组织中的有效性及其内在作用机理,以发现适合我国文化特点的管理方式.实证研究了家长式管理广泛存在于所有的组织结构中,而其中用德行管理具有更高的效能.     

Environmental Policy Instruments: Technology Adoption Incentives with Imperfect Compliance

We study the incentives to adopt advanced abatement technologies in the presence of imperfect compliance. Interestingly, incentives under emission taxes and pollution abatement subsidies are the same that in the perfect compliance scenario. However, under emission standards imperfect compliance can increase firms’ incentives to invest, whereas under an emission permit mechanism investment incentives decrease only if widespread non-compliance induces a reduction in the permit price. Our results are valid for fairly general characteristics of the monitoring and enforcement strategies commonly found in both, theoretical and empirical applications.     

A simple random assignment problem with a unique solution

Summary. All agents have the same ordinal ranking over all objects, receiving no object (opting out) may be preferable to some objects, agents differ on which objects are worse than opting out, and the latter information is private. The Probabilistic Serial assignment, improves upon (in the Pareto sense) the Random Priority assignment, that randomly orders the agents and offers them successively the most valuable remaining object. We characterize Probabilistic Serial by efficiency in an ordinal sense, and envy-freeness. We characterize it also by ordinal efficiency, strategyproofness and equal treatment of equals.

Stackelberg financial-leader in insider trading model

In this paper, we extend the Jain-Mirman [Jain, N., & Mirman, L. (2000). Real and financial effects of insider trading with correlated signals. Economic Theory, 16, 333–353, Jain, N., & Mirman, L. (2002). Effects of insider trading under different market structures. The Quarterly Review of Economics and Finance, 42, 19–39] and the Daher-Mirman [Daher, W., & Mirman, L. (2006). Cournot duopoly and insider trading with two insiders. The Quarterly Review of Economics and Finance, 46, 530–551, Daher, W., & Mirman, L. (2007). Market structure and insider trading. International Review of Economics and Finance, 16, 306–331] papers on competition, and postulate that the competition among the insiders in the financial market be Stackelberg. However, an owner high in the organizational hierarchy, who designs manager compensation mechanisms and chooses a manager to serve his purpose, should have information on the manager's reaction and act as a Stackelberg leader in the financial sector. We show that owner's profit can definitely enlarged while the manager's profits may decrease or increase depending on the variances in the two sectors, which are the exogenous parameters.     

DISCRETE CHOICE AND RATIONAL INATTENTION: A GENERAL EQUIVALENCE RESULT

This article establishes a general equivalence between discrete choice and rational inattention models. Matějka and McKay (2015) showed that when information costs are modeled using the Shannon entropy, the choice probabilities in the rational inattention (RI) model take the multinomial logit form. We show that, for one given prior over states, RI choice probabilities may take the form of any additive random utility discrete choice model (ARUM) when the information cost is a Bregman information, a class defined in this article. The prior information of the rationally inattentive agent is summarized in a constant vector of utilities in the corresponding ARUM.
