银行间和交易所债券市场信息溢出效应研究

本文采用VAR模型研究了我国交易所和银行间国债市场的信息溢出效应.笔者提出以往文献对两个国债市场信息溢出的结论过于简单化,实证验证了两个市场信息溢出时既具有差异性又具有同质性,哪种性质占主导取决于新信息的来源.笔者发现当新信息来源于国债市场内部,两个国债市场会表现出差异性,溢出效应为负向,即银行间国债市场的上升预示着交易所国债市场的下降.当信息来源于国债市场外部,两个国债市场之间则先表现出同质性,溢出效应为正向;随后差异性占主导,两个国债市场之间发生信息负向溢出或资本的流动.     

个体异质性与公共物品治理的关系研究

公共物品治理如何摆脱囚徒困境?研究者试图通过建立数理模型讨论个体异质性对公共物品治理成功的作用。梳理了个体异质性与公共物品治理的关系研究思路,基于前人的相关理论模型和实证工作,给出了公共物品治理中如何将个体间异质性纳入形式化讨论、并用经验现实予以检验的一个展望。     

健康的不确定性与预防性劳动力供给——来自中国农村地区的经验证据

文章采用理论分析和实证研究相结合的方法,在经济学效用函数理论框架内考察健康不确定,巨对中国农村非农劳动力供给行为的影响.理论分析表明,在健康存在不确定性的情况下,农村非农劳动力供给存在预防性劳动力供给现象,拥有医疗保险可以显著降低预防性劳动力供给.采用CHNS数据的实证研究结果支持预防性劳动力供给的理论推断.     

\"公地悲剧\"理论在新疆耕地利用的新解析

\"公地悲剧\"是产权不清的情况下\"公地\"资源配置失效,被过度使用而枯竭的过程。近年来,该理论被广泛应用于环境科学、经济学、社会学、政治学等领域。本文分析了新疆耕地数量变化与粮食安全、耕地质量变化与生态环境建设、耕地开发利用变化与地区发展战略等情况,从新疆特殊的自然环境条件、管理审批权限、水土资源开发配置、农户农耕理念等方面出发,论述了\"有主之地\"的耕地也存在\"公地悲剧\"现象。     

租金外溢还是知识外溢?——一个文献综述

构建权重矩阵来衡量研发外溢是最常用的衡量间接研发资本的方式,常用的是基于贸易额、专利信息和投入产出信息等来构建权重矩阵,但其中存在较多争议的是基于专利信息所构建的权重矩阵。通过对有关文献进行梳理,以及其所对应的衡量方式进行综述,发现以往对研发外溢的衡量主要侧重于宏观层面,如国家或行业层面,但对企业研发外溢的衡量较少,因此,对企业研发外溢的衡量是后续研究的主要侧重面。

Policy Rules for Exploitation of Renewable Resources: A Macroeconomic Perspective

A fundamental problem for an economy based on a common property resource is the absence of a market to trade the resource. This implies that private costs will be below social costs. This paper investigates possible government interventions that correct for such distortions in a neoclassical growth model with a production externality in harvesting. The model predicts that the welfare of the representative household increases considerably when a Piguovian tax is implemented. The policy that replicates the command optimum is highly complex and changes over time. On the other hand, a large share of the maximum welfare increase is internalized by introducing a constant quantity tax, suggesting that the potential of such policies is high.     

独立审计社会信用奖惩机制效应实证分析

以商务部公布的会计信息质量检查公告及证监会处罚公告检查结果作为研究背景,选取2003—2012年会计师事务所的客户量及综合收入为研究数据,从激励和惩罚两个机制对数据进行实证研究,并从信息论、监督论和保险论3个方面描述了独立审计的功能。通过市场整体对被处罚会计师事务所的反应情况得出结论,认为在我国资本市场中,独立审计社会信用惩罚机制发挥着有效与失效并存的作用。     

Technological Change: Disaggregation and Overseas Production

The Russian economy faces serious challenges when it comes to such issues as legitimacy of property and protection of property rights. This paper considers institutional aspects of raiding, including the role of Commercial Arbitration Courts and bankruptcy procedures in Russia. It concludes that raiding in Russia has a predatory character not because raiders prey on the weakest, failing, bankrupting businesses, but because they attack healthy and profitable enterprises, firms in temporary financial distress. Raiders use unclear ownership structure of attractive firms and buy necessary decisions from corrupt bureaucrats instead of waiting for a financial crisis to come.     

关于银保合作的几点思考

It Investment and its Productivity Effects: An Organizational Sociologist's Perspective on Directions for Future Research

The paper reviews the empirical evidence on the contribution of IT investments to economic growth and discusses the need for further research to explain the chain of causation linking the cumulative effects of IT expenditures on vertical and horizontal market structures within specific industries and the factors which influence or mediate the direction and magnitude of these effects. Two hypotheses are discussed as polar explanations for why IT capital productivity increased significantly after such a long period of stagnant and, in some industries negative, growth prior to 1987.     

Information sharing about a demand shock

This paper examines two questions in asymmetric Cournot and Bertrand oligopoly with a demand shock. Under which conditions is information sharing a subgame-perfect equilibrium? What is the welfare effect when firms are better off? Given these questions, the normal assumptions in the earlier literature can be relaxed in three ways: demand functions can be asymmetric; a demand shock can affect firms differently; distributions of the demand shock and information signals can be arbitrary. Under these general assumptions, the answer to the first question is: every firm's response to the demand shock is stronger when all firms have perfect information than when one firm does so alone; the answer to the second question is: social welfare increases in Cournot competition, and consumer surplus decreases in Bertrand competition.     

价格离散、信息搜寻与团购行为

团购行为是当今消费行为学中的一个重要现象,源自市场和产品信息不对称的双重因素是导致消费者行为变化的根本原因。基于产品信息的价格函数模型,分析团购有利于消费者实现信息共享,减少搜寻成本,降低与企业间的信息不对称,减少消费行为的不确定性,从而获得更大的消费效用的结论。
