粮食安全、收入约束与生物燃料替代--基于跨国面板数据的实证研究

根据2000_2010年跨国面板数据,利用随机效应tobit模型研究粮食、环境和能源对全球生物燃料替代化石燃料使用的影响。研究发现：粮食安全程度高的国家生物燃料替代程度较高,而生物燃料的过度发展有可能导致“与粮争地”和国际粮食市场价格上涨,从而危及粮食安全;碳排放强度能促进生物燃料替代水平的提高,但前提是该国具有较高的国民收入水平;能源安全考虑仅仅在发达国家内能影响生物燃料替代。相关结论为各国制定适合本国粮食安全状况和经济发展水平的生物燃料替代目标提供参考依据。     

Gains,Losses, and the US-EPA <Emphasis Type="Italic">Economic Analyses Guidelines</Emphasis>: A Hazardous Product?

While offering many useful suggestions to improve economic analyses, the Guidelines take no account of widely reported behavioural economics research findings. Foregoing the opportunities to improve valuations and other analyses offered by this evidence is likely to lead to inappropriate assessments and consequent distortions of damage estimates, policy and regulatory design. JEL classifications: C91, D61, H43 This review is in part based on studies supported by the U.S. Forest Service and has benefited from comments and suggestionss of Bas Donkers, Robin Gregory, the editor, and referee.     

中国城镇家庭住房来源与产权的省际差异——基于2000年人口普查资料的分析

根据中国2000年人口普查资料,分析了中国城镇家庭住房来源与产权的省际差异。住房来源与产权选择省际差异不明显;基本是沿海经济发达地区住房来源中商品房来源与产权选择中租赁商品房比重高。相关分析表明:地区市场化指数与市场型住房正相关,收入和产权关系不明显,国有经济比重与行政型住房正相关,城市化率与购商品房比正相关,价格和住房产权负相关。这说明了制度变迁和地区经济差异对住房选择的影响。     

全面收益理论与损益确认原则--实现原则、权责发生制原则利弊谈

收益指标是财务报表使用者特别是投资人最为关心的会计信息.美国会计学者利特尔顿认为,收益是企业会计的重心,收益表是企业会计最重要的产品.历史成本原则、实现原则、配比原则是传统收益确定模式的重要支柱.全面收益突破了实现原则,更好地体现了权责发生制原则的要求,并在会计确认中坚持了适当稳健的原则,有利于提供与信息使用者决策相关的可靠信息.     

对中国景区门票价格制定的思考

文章总结了不同类型门票价格的制定原则以及门票价格的作用,并据此对中国景区门票价格制定的现状问题进行了阐述和分析,指出中国大部份景区在制定价格时没有充分发挥门票价格的作用,以国家公园为代表的资源型景区的门票收入分配问题也成为业内关注的焦点。最后,文章从定价理念、规范化管理和增强景区综合赢利能力等三方面提出了建议。     

Alan Gillie,Input-Output Economics.

Turnovsky observes that “the rational expectations hypothesis has had a profound impact on macroeconomic theory and policy during the past decade.” Tracing briefly the evolution of the ideas involved, he concludes that “… a consensus view is emerging that in fact under quite plausible conditions the policy neutrality proposition does not hold; therefore, there is still scope for policy rules to play an important role in stabilizing output.”

The mathematics used in the article is expository rather than analytical, requiring of the reader only somewhat more than the usual amount of persistence, faith in the author's interpretation of the literature, and a willingness to accept the integrity of economic models as representative of the real world. This is “required” reading for those teaching macroeconomics.
