Consistency and optimality in a dynamic game of pollution control II: Monopoly

This paper continues a line of research begun in Batabyal (1995a). I model the interaction between a regulator and a monopolistic, polluting firm as a Stackelberg differential game in which the regulator leads. The firm creates pollution, which results in a stock externality. I analyze the intertemporal effects of alternate pollution control measures. The principal issue here concerns the dynamic inconsistency of the optimal solution. Inter alia, I compare the steady state levels of pollution under optimal and under dynamically consistent policies.

长江中游根治洪灾策略与措施的探讨

长江中游是长江自然—经济—社会复合生态系统的重要组成部分,当前洪涝灾害频繁而严重。按照长江洪水发生的自然规律调整好人与自然的关系,改变长期以来舍南保北、以堵为主、重蓄轻泄的做法,实施疏泄为主的防洪策略,并采取相应的工程和非工程措施(如下荆江裁弯、开辟分流洪道、四口建闸、洞庭湖水系南北分流、疏浚河道、南水北调及平垸行洪等),同时配合进行水源生态工程及江河库湖调蓄工程建设,才能根治长江中游洪涝灾害。     

Environmental regulation and profitability: An application to Swedish pulp and paper mills

In this paper we analyze the impact on firm profits of the environmental regulations in the Swedish pulp and paper industry. The approach taken is a non-parametric programming model of the technology. A feature of this industry is that environmental regulations are determined individually for each mill. A question, then, is if these individual regulations have a similar impact on firm profits. The approach in this paper allows us to calculate both the regulated and unregulated profits, which means that the severity of the regulations, in terms of foregone profits, can be calculated for each mill. The empirical result shows that the impact on the mills varies substantially, and that the burden from the regulations is less severe in 1990 than in 1989.     

会计管制与公司治理

本文从企业契约理论出发,在回顾会计管制国际经验的基础上,将会计管制引入对公司治理问题的思考,指出了会计管制目标的实现对解决公司治理问题的重要性。其不仅要求反思会计管制理论与实践,同时要求在具体分析公司治理模式的基础上,重新思考会计管制的目标及其实现问题。提出应从现行公司治理框架下改进会计管制措施,从而实现会计管制与公司治理的良性互动。     

The Case of the Missing Pollution Haven Hypothesis

One particularly vexing puzzle for economists and policymakers over the past several decades concerns the empirical significance of the theoretically predicted pollution haven hypothesis. While neoclassical theory and conventional wisdom both surmise that local economies will suffer deleterious effects from stricter environmental regulations, empirical studies have largely failed to validate such claims. This study utilizes the method of matching to show that the impact of stricter regulation is heterogeneous spatially, varying systematically based on location-specific attributes. Previous studies that assume a homogenous response may therefore inadvertently mask the overall impact of more stringent regulations by pooling unaffected and affected regions.JEL Classification: Q25, Q28, H00, L51, R1The authors wish to thank to Michael Crew, Anthony Heyes, an anonymous referee, Werner Antweiler, Randy Becker, Wayne Gray, Shelby Gerking, Michael Greenstone, Vern Henderson, and Arik Levinson.

机场环境管制探讨

机场环境管制的重点是噪声和排放物污染。除直接管制外,收费是国外机场环境管制中应用得最多且最有效率的经济管制方式。我国除继续强化已有的直接管制方式外,还可以从收取以保护环境为目的的噪声费和排放物费、限制机场土地的使用、采取国际机场协会提出的短期和长期机场环境保护措施三个方面进一步加强机场环境管制。     

WTO中紧急保障措施谈判僵局及对策

紧急保障措施是WTO新一轮服务贸易谈判中的三个重要议题(紧急保障措施、政府采购、补贴)之一.自上个世纪90年代以来紧急保障措施的谈判一直陷于僵局,谈判各方分歧较大.从各成员方的所处地位和利益方面对紧急保障措施陷于僵局的原因进行分析,可得出解决该问题的模式,对我国在今后积极参与谈判制定服务贸易游戏规则,维护我们的利益有一定的参考价值.

论生态环境规制改革

生态环境（产品）几乎都有外部性问题,生态环境领域是公共产权进入最为密集的领域,因此公共规制在生态领域具有巨大的潜在作用。在我国生态环境规制改革进程中,既要强化对生态规制者的规制、建立生态公共租金消散机制,又要放松规制与优化规制并举,实行政企分开的生态规制体制,对规制者和被规制者引入激励性规制,优化政府的生态规制手段和生态规制结构,克服市场失灵与规制失灵给生态环境带来的弊端。
