Theory and practice of monetary policy

Summary. We consider an optimally managed renewable resource with stochastic non-concave growth function. We characterize the conditions under which the optimal policy leads to global extinction, global conservation and the existence of a safe standard of conservation. Our conditions are specified in terms of the economic and ecological primitives of the model: the biological growth function, the welfare function, the distribution of shocks and the discount rate. Our results indicate that, unlike deterministic models, extinction and conservation in stochastic models are not determined by a simple comparison of the growth rate and the discount rate; the welfare function plays an important role.Received: 20 October 2004, Revised: 28 February 2005, JEL Classification Numbers: D90, O11, O41, Q32.Santanu Roy: Correspondence toResearch on this paper was completed when the second author visited Cornell University in July, 2003.

中美审计结果公告制度实施环境的比较及启示

审计结果公告在发达国家是一种通行做法,近年来我国也颁布了相关的法律法规,但完整的审计结果公告制度尚未建立。审计结果公告制度的建立是一个系统工程,受政府信息公开程度、审计模式、审计规范体系等环境因素的影响和制约。文章从以上环境因素着手,分析比较了中美审计结果公告制度的异同,以期对我国审计结果公告制度建立和健全提供参考。

Domestic and international strategic interactions in environment policy formation

Summary. In this paper, we establish the most possilbe general formulation of the technology governing carbon-gas emission, giving rise to global external diseconomies, and ty to explore into the strategic interactions,both domestic and international, when an individual country decides on the environmental policies. Through the comparison among emission taxes, quotas, and standard in the perfectly competitive private economies, we find that the first two policies are equivalent but they are different in effects by virtue of what we may call the tax-exemption effect of emission standards. Such a difference in the policy effect further affects the other country's welfare through the global externalities, amplified through whether the government can precommit to either the emission tax or the emission standard.

政府推动农业标准化的职能定位

农业标准化已经是世界农业发展的趋势.分析了政府推动农业标准化的理论依据和职能定位,认为政府干预是农业标准化的必然要求,其发挥作用的领域主要限定在制度供给和公共服务方面,而标准的制定应该在法规的引导下以农户和企业为主导.我国目前在促进农业标准化过程中,政府应合理界定其职能范围,致力于法规体系和检测体系的完善和农业标准信息、咨询、培训服务的加强.
