Optimality conditions¶and bubbles in sequential economies¶and bounded relative risk-aversion

We provide specific qualifications in order that Kuhn–Tucker type Euler equations and transversality conditions at infinity hold in stochastic equilibrium models with heterogeneous agents and where assets are traded in sequential markets. It is not assumed that uncertainty is modeled as an event-tree structure or that preferences are necessarily bounded. We also describe an important class of preferences based on bounded relative risk aversion which yields relevant simplifications. Our results are used to establish conditions that rule out asset pricing bubbles. Specific examples of economies with bubbles are also discussed.

Theory and practice of value management and its innovation for natural resources from the perspective of sustainable development

The supreme obstacle for sustainable development of natural resources is the scarecity, bottleneck. So how to promote the sustainable utilizing and increase the using efficiency of natural resources is worth studying. This paper suggests that we should improve the model and means of evaluating method and value management based on th~ theory of natural resource compensation. This paper discusses the User Cost Method based on the microeeonomicaspect which can change the evaluating method for natural resources. From the perspective of value managemen model, we should use the User Cost Method to realize the linkage and integration of micro and macro eompensation for natural resources. Based on the evaluating and aecounting idea User Cost Method, this paper presents a theo. retical framework to harmonize and link micro and macro compensation for natural resources. At present, we should seek the new approach and method to manage natural resources, so can we realize the capitalization managemen focusing on the vahte management for natural resources.

The natural environment factor, the customer factor, and the political factor have played crucial roles in the formation and development of GNOCIC. Among them, the rich natural resource and the superior geographical environment are the material base. And government＇s support is the main propelling force. The customers＇ expense is the final decision strength by chance which it develops, expands.     

产业集群竞争力分析——以辽宁汽车产业集群为例

运用一种研究产业集群竞争力的量化分析工具——GEM模型,构建了辽宁汽车产业集群竞争力评价表,对该集群的各要素进行了竞争力的综合分析。分析结果表明:辽宁汽车产业集群在全国范围内已经有一定的竞争力,但在设施、企业结构、战略和竞争方面得分都低于全国平均水平,已成为制约其进一步发展的瓶颈因素,因而从"基础","企业","市场"方面给出了提升辽宁汽车产业集群竞争力对策建议。
