言息科技革命与反垄断法的冲突——微软公司VS．美国司法部案例分析

科技进步所诱发的信息革命给我们经济、法律、文化、伦理等社会关系造成了巨大的冲击。其中,建立于传统经济运行模式基础上的监管规制(尤其是反垄断法)在信息时代中显得难以应付,这集中表现于美国司法部与微软公司的世纪之诉中。因此,通过分析微软公司的案例,指出了反垄断立法背后的理论基础并不能囊括信息时代企业的竞争行为,因此有必要研究与信息经济时代特征相适应的反垄断立法。     

Corporate Lobbying, Regulatory Conduct and the Porter Hypothesis

Michael Porter, the influential Harvard management guru, has promoted the idea that compliance with stricter environmental regulations can afford secondary benefits to firms through improved product design, innovation, corporate morale and in other ways. Once these secondary benefits are factored, the net cost of compliance is argued to be lower than conventionally thought and may even be negative. Whilst environmental economists have rejected the Porter Hypothesis as being based on excessively optimistic expectations of the likely size of such secondary benefits the underlying ideas do enjoy significant credence in the business community. In the context of a lobbying model of regulatory policy-making we argue that the EPA should change the way it conducts regulatory policy to take account of Porter's views – even if it knows those views to be misguided. The model serves to illustrate the more general point that fashions in management thinking can be expected to impact the optimal conduct of regulatory policy.

物料流量会计的深化——利用MFCA与LCA的整合评估外部损害成本

物料流量成本会计(MFCA)是一种环境管理会计运用工具,也是企业高级管理人员和现场生产经理制定决定的一种工具.MFCA通过减少废弃物来实现提高生产能力的目标.MFCA衡量了材料的物量和存量信息,即在生产过程中的原材料、备品备件以物流和货币的单位表示出来,将MFCA与生命周期评价(LCA)整合,以此来评估外部损害成本.     

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.     

Strategic Environmental Standards, Wage Incomes and the Location of Polluting Firms

The purpose of this paper is tostudy how the choice of environmental standardsby governments is affected by the existence ofwage incomes when firms locations areendogenous. In developed countries labor isunionized, which allows positive wage incomesto arise. Thus, each government has incentivesto persuade firms to locate in its countrysince social welfare depends on suchincomes. But, as pollution damages theenvironment, each government will only try toattract polluting firms to thecountry, to obtain the wage incomes, whenthe valuation of environmental damage showsthat it is low.     

成都创建国家环境保护模范城市的启示

成都市创建国家环境保护模范城市活动进一步改善了城市创业环境和人居环境,全面提升了城市服务功能与综合价值,提高了公众生活质量,使成都市初步走上了环境和经济相互促进,人与自然和谐共生的可持续发展道路,呈现出经济快速发展、环境清洁优美、生态良性循环的良好态势。从成都创建国家环境保护模范城市实践中,我们可以得到以下启示:创建国家环境保护模范城市是构建和谐社会,落实科学发展观,全面建设小康社会,提高城市综合实力与城市竞争力的前提;创建国家环境保护模范城市必须承担发展经济和保护生态的双重任务,并且需要建立持续增长的投入机制;国家环境保护模范城市建设更需要注重生态型社会的建设。     

Simultaneous versus sequential information processing

Subjects update prior information simultaneously versus sequentially. The mean prediction is remarkably close to the correct Bayesian estimate with simultaneous information, but differs significantly conditional on whether good news precedes bad news or vice versa.
