汇率决定理论的新近发展:文献综述 总被引:15,自引:0,他引:15
传统汇率决定理论对于现实经济中汇率实际变动情况的解释能力十分低下.20世纪80年代以来,学术界不断寻求突破,以期为汇率如何决定这一基本命题提供更为合理的解释.在这一过程中,不断有新的文献出现,从不同的方面对传统的汇率理论进行补充、发展和替代.鉴于此,本文试图对汇率决定理论的新近发展进行梳理和介绍,借以为国内经济学界研究汇率决定问题提供一个理论参考. 相似文献

当前,国内民营经济发展主要有三种模式,即温州模式、苏南模式和青浦模式.三种模式对发展我国民营经济都具有借鉴意义,但不能照搬照抄.民营经济发展战略是一项复杂的系统工程,民营经济发展可采取集团化战略、多元化战略、融资战略、人力资源开发战略等四种战略,这四种战略都具有现实意义. 相似文献

This paper suggests that while the static welfare losses of merger predilections among Western firms may not be dramatic, they may lead to substantial dynamic losses when merger-prone firms need to compete with firms which instead focus on equipment investment and investments in R&D. It is suggested that such diverging investment priorities have been the real cause of the deteriorating competitiveness of many of the largest Western enterprises vis-à-vis their Japanese rivals. While mergers are generally taken to be determined by either efficiency or monopoly considerations, this paper argues that Western merger predilections are likely to be generated by a combination of imitative and defensive routines as well. That would make it difficult for firms to unilaterally break away from these competitiveness-threatening investments. If correct, this would imply that competition policies would need to be refocused. However, it is also suggested that the implications for international competitiveness should make merger questions a subject of industrial policies too. In that respect, the paper suggests some basic attitudinal changes.Earlier versions of this paper were presented at a Global Forum for Competition and Trade Policy conference in Vienna and at a EUNIP workshop at Åbo Akademi University, Finland.

An economic system which exhibits chaotic behaviour has been stabilized on various periodic orbits by use of the Ott-Grebogi-Yorke method. This procedure has been recently applied to controlling chaotic phenomena in physical, chemical and biological systems. We adopt this method successfully for Feichtinger's generic model of two competing firms with asymmetrical investment strategies. We show that the application of this control method to the particular economic process considered brings a substantial advantage: one can easily switch from a chaotic trajectory to a regular periodic orbit and simultaneously improve the system's economic properties. Numerical simulations are presented in order to illustrate the effectiveness of the whole procedure.The work was supported by the Alexander von Humboldt-Stiftung and by the Polish National Council (KBN) Grant No 2 P302 038 04. 相似文献

Protecting human health is a primary goal of environmental policy and economic evaluation of health can help policy-makers judge the relative worth of alternative actions. Economists use two distinct approaches in normatively evaluating health. Whereas environmental economists use benefit-cost analysis supported by monetary valuation in terms of willingness-to-pay, health economists evaluate interventions based on cost-effectiveness or cost-utility analysis (CEA), using quality-adjusted life-years (QALY) or similar indexes. This paper provides background on the controversy about the relative merits of these approaches and introduces the remaining papers in the special issue. These papers (with one exception) were presented at a conference sponsored by the Department of Economics at the University of Central Florida with support from the US Environmental Protection Agency. Although CEA might not lead to substantially different implications for environmental policy than benefit-cost analysis, and QALY may provide a benefit transfer tool to fill gaps in the morbidity valuation literature, the papers in this issue raise serious concerns about the suitability of QALY-based CEA for environmental regulatory analysis. QALY does not in general appropriately represent individual preferences for health and CEA is neither independent of income distribution nor adequate to assess efficiency. 相似文献

金融发展、资本账户开放与金融不稳定——来自中国的证据 总被引:1,自引:0,他引:1
文章建立一个由金融发展程度、资本账户开放与金融不稳定指标组成的向量自回归(VAR)模型,利用中国1982~2005年的年度数据对这些变量的长期协整关系和短期的调整动力学进行相关的时间序列分析。模型的估计结果显示,对于中国来说,金融发展程度、资本账户开放和金融不稳定之间存在着长期的协整关系,但三者之间的影响程度和方向各不相同。所有结果均显示,无论从短期和长期看,金融发展程度对一国的金融稳定具有显著影响,对资本账户开放的进程也具有重要的影响。 相似文献
