Subjective Uncertainty over Behavior Strategies: A Correction

In order to model the subjective uncertainty of a player over the behavior strategies of an opponent, one must consider the player's beliefs about the opponent's play at information sets that the player thinks have probability zero. This corregendum uses “trembles” to provide a definition of the convex hull of a set of behavior strategies. This corrects a definition we gave in [E. Dekel, D. Fudenberg, and D. K. Levine, 1999, J. Econ. Theory89, 165-185], which led to two of the solution concepts we defined there not having the properties we intended.

Dynamic modelling of pollution abatement in a CGE framework

This paper deals with the specification of pollution abatement in dynamic computable general equilibrium (CGE) models and analyses the dynamic feedback mechanisms between economy and abatement in the context of environmental policy. A Ramsey-type economic model is presented, in which bottom-up technical and economic information on abatement techniques is integrated in a top-down dynamic CGE context. The practical suitability of the specification is illustrated by an empirical application for climate change and acidification in the Netherlands. The results show that a mixture of some slowdown of economic growth, a substantial restructuring of the economy and implementation of most technical abatement measures is optimal.     

不完全合同、退出的激励平衡和控制权转移

文章针对创业资本退出时控制权转移问题,构建了基于不完全合同理论的分析框架。首先,文章在合同完全和不完全两种情况下分析了创业投资中的相机控制,得出这种制度安排的根源在于投资双方的激励不平衡的结论;其次,文章分五种情况具体探讨了控制权如何进行转移。     

消费和谐论:面向科学发展观的消费理论

文章从消费系统均衡的角度出发，运用一般均衡原理研究了消费系统实现均衡的和谐机制，探讨了消费者在和谐机制运行中的主导地位，进而分析了消费和谐论与科学发展观的有机统一。最后指出以人为本、协调发展、提高消费在GDP中的比重对于科学发展观和消费和谐论的重要性。     

应用电法新装置勘探二维与三维地电体

本文通过对新装置条件下位场特征的分析,应用边界单元法及解析法的计算结果,发现当二维或三维电性不均匀体与测量电极位于背景场同一等位面时,视电阻率异常反映最明显。从而提出了圆弧交会法确定二维或三维地电体中心理深的方法,并给出了若干计算实例。结果表明,此方法简便有效且精度较高。     

投机资本攻击一国汇率的博弈均衡

在经济全球化和金融自由化背景下,国际投机资本的力量快速膨胀,国际游资利用金融杠杆掠夺危机国的财富,使国际金融市场的稳定受到严重挑战.通过构建两个不完全信息下微观主体的博弈模型,揭示国际投机者做出投机攻击决策的依据和博弈中货币当局败北的原因,创造性地提出"抗投机攻击指数"的概念,用以判断一国外汇市场的稳定,为我国在金融市场对外开放过程中采取有效政策搭配、实现内外均衡提供参考.

On a clear day you might see an environmental Kuznets curve

We shed some new light on the Environmental Kuznets curve (EKC) and show how it can be viewed as a particular form of equilibrium relationship, where technology and preference parameters determine the shape of the curve. In contrast to most of the literature on the EKC, we estimate a theoretically consistent model on long-run data (Swedish sulfur emission, covering the period 1900–2002). Furthermore, we test and date structural change. The model suggests four regimes, 1900–1918, 1919–1933, 1934–1967 and 1968–2002, generating four rather different patterns for pollution over time. The policy-conclusions are consonant with Pearce’s general view about the EKC: there is no theoretical presumption that it has an inverted U shape, nor should any country try to “grow out of the environmental problems” without analyzing the benefits and costs of so doing.     

Innovation, Imitation and Intellectual Property Rights: A Note on Helpman's Model

This note analyses the effect of the policy of tightening Intellectual Property Rights (IPR) on the rate of innovation in the North and on the welfare in both North and South in a model which is otherwise identical to Helpman (1993) except in the concept of knowledge capital. We assume that the South based imitated products do not contribute to the knowledge capital in the North. It is shown that the tightening of IPR raises the rate of innovation in the North and may improve the welfare of both North and South. These results are significantly different from those in Helpman (1993).
