PFI模式与基础设施供给

传统观念认为 ,基础设施服务的供给是政府一个很重要的职能。但是近年来 ,随着实践和理论的发展 ,这种观念开始发生变化。人们开始探索新的基础设施服务供给模式并取得了良好的效果 ,PFI模式主是其中最具代表性的一种。对目前基础设施服务供给的现行模式进行了分析 ,并阐述了英国用以解决基础设施服务供应所采用FPI模式。提出了借鉴英国PFI模式发展我国基础设施产业的政策建议。     

论贸易政策合理性的评价标准及反倾销的不合理性

目前，国内学界对反倾销的合理性问题存在着激烈的争论。合理性问题是一个评价问题，合理性评价的前提是合理性的评价标准。国内学界在对反倾销合理性问题进行争论的时候忽略了这一前提，即没有给反倾销合理性确定一个比较明确的评价标准，这就使这种评价失去了依据。文章从合理性的含义出发，提出了贸易政策是否具有合理性的三个评价标准，并在此基础上对反倾销的不合理性进行了分析和探讨。     

“一带一路”倡议下我国重点省市物流绩效评价研究

物流建设是“一带一路”倡议发展的重点。通过物流设施建设、拓展物流业发展的新方向,促进地区融合、加强多边贸易、加速互联互通,是我国现行经济格局下“一带一路”重点建设省市物流发展的新走向。文章从政府行为、社会效益、服务水平三个维度构建了包含地区经济、物流政策、数字物流等14个指标的物流绩效评价指标体系,利用数据包络法对我国“一带一路”重点建设省市的物流绩效进行评价,发现我国物流业发展存在地区差异大、服务水平过低的现象。结合地方政府的政策解读,发现我国地区物流绩效水平呈现出一定的政策相关性,可通过合理的政策引导促进地区物流业的发展。

Overlapping Generations or Infinitely-Lived Agents: Intergenerational Altruism and the Economics of Global Warming

Do we need an overlapping generations model for the economics of global warming? To answer this question, an infinitely-lived agent (ILA) approach and an overlapping generations (OLG) model are contrasted. ILA and OLG can be viewed as polar representations of intergenerational altruism. With ILA an immortal agent acts through his investment/savings decisions as trustee on the behalf of the future generations. With OLG, agents need not behave altruistic. They simply save during working years and dissave completely during retirement. Nevertheless, ILA and OLG must not differ in their implication for greenhouse policy. Greenhouse gas abatement is a straightforward alternative to physical capital formation and, even without altruism, each age cohort has an incentive to provide current abatement in order to reduce future damages attributable to climate change. Indeed, under reasonable assumptions and parameter values, our simulations reveal such an invariance result. Provided carbon taxes are the only policy tool and tax revenues are recycled through socially mandated rules, projections of economic growth, climate change and energy consumption are only insignificantly affected by the choice of approach.     

Assessing Voluntary Programs to Improve Environmental Quality

The last decade has seen a dramatic increase in the use of voluntaryapproaches (VAs) to environmental protection, which has spurned agrowing literature on the relative merits of voluntary vs. mandatoryapproaches. This paper draws on that literature to discuss both thetheoretical and empirical issues that arise in the evaluation orassessment of a particular VA. We consider both the environmentaleffectiveness and the efficiency of this policy approach. Our aim is toaid policymakers in evaluating a specific program or in thinking aboutthe use and design of a VA. We identify some key features that arelikely to increase both the effectiveness and the efficiency of VAs.     

股票市场的货币政策传导分析

货币政策的传导机制不是唯一的，金融市场的种种特征造成了货币政策传导的多样性，股票市场中的货币政策传导就具有独特的规律，在不与银行信贷的创造机制相连的前提下，信贷资金和股市资金的沟通是合理的，目前中国信贷市场和股票市场之间千丝万缕的关系，并没有为货币政策传导创造更加有效的机制基础，股票市场还不能成为货币政策的有效传导渠道。     

Voting requirements, concessions, international side payments and the European Monetary Union

This paper addresses the question of criteria for selection of EMU members. We identify two factors in the decision process: (1) The costs and benefits which the individual countries attribute to alternative EMU arrangements (`hard-core', medium-sized, all EU members), and (2) the binding institutional restrictions, i.e., the distribution of votes in the European Council and the minimum vote requirements. Within this framework the EU countries are assigned to different groups according to their degree of convergence. Based on stability concessions and side payments these groups decide on the final EMU composition. We show that minimum vote requirements can lead to a suboptimal size of the EMU and can threaten the feasibility of a multi-speed monetary union.     

Economic Valuation of Health for Environmental Policy: Comparing Alternative Approaches. Introduction and Overview

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.
