In this paper we study the optimal conversion policy set by a society composed of a sequence of non-overlapping imperfectly altruistic generations. We show that society can be equivalently viewed as a sequence of hyperbolic discounting agents. Under uncertainty about future pay-offs we determine, as solution to an intergenerational non-cooperative dynamic game, the optimal timing of irreversible conversion. We show that under both naive and sophisticated beliefs about future time-inconsistency, the option value attached to the conversion decision is eroded and earlier conversion occurs. This determines a drastic bias toward the current generation gratification, which affects the intergenerational allocation of benefits and costs from deforestation. 相似文献

渔业补贴的类型及演变 总被引:2,自引:2,他引:2
渔业补贴被认为是引发过渡捕捞、扭曲国际贸易的重要因素,日益引起关注。本文概述了渔业补贴的基本类型,包括政府对行业的直接支付、税收减免和延期、政府贷款及贷款担保和保险、对行业的隐性支付或隐性收费、对渔业有影响的一般性政策或计划,并分析了各类补贴的性质和作用。通过简述美国、加拿大、挪威、冰岛等国渔业补贴政策演变历史,说明了渔业补贴问题的复杂性。 相似文献

近年来,渔业补贴问题一直是国际论坛争议的焦点之一。各相关国际组织、相关学者以及主要渔业国对渔业补贴都做了不同领域的研究。其中,就渔业补贴的评估,一些国际组织也提出了不同的定量分析方法。本文探讨了经济合作发展组织以及世界粮农组织提出的两种渔业补贴评估法,以便我国在定量分析考察渔业补贴效果时加以参考。 相似文献

休闲渔业的发展需要建立分类补贴的补贴机制。补贴原则上,要突出重点,控制总量;注重公平,遵循市场规律;讲究效益,科学发展;因地制宜,合理布局。补贴类型上,要区分整体类补贴和个别类补贴的差异,按照不同的类别建立相应的补贴流程。补贴手段上,要运用好长期补贴与短期补贴、一次性补贴与分阶段补贴等方式。分类补贴机制建立和实施将遇到诸多困难,为提供工作效率,应该实行规范化操作、控制实施分类补贴的成本、完善监督和信息公开机制。 相似文献

Fat taxes and thin subsidies: Prices, diet, and health outcomes 总被引:1,自引:0,他引:1

“Fat taxes” have been proposed as a way of addressing food-related health concerns. In this paper, we investigate the possible effects of “thin subsidies”, consumption subsidies for healthier foods. Empirical simulations, based on data from the Continuing Study of Food Intake by Individuals, are used to calculate the potential health benefits of subsidies on certain classes of fruits and vegetables in the United States. Estimates of the cost per statistical life saved through such subsidies compare favorably with existing U.S. government programs. 相似文献

Among the several propositions advanced to explain the rising cost of subsidizing soft wheat production and consumption in Morocco are the indirect effects emanating from related markets, namely the hard wheat and barley markets. A three-sector supply-demand model, described in this paper, was used to estimate the direct and indirect (induced) effects on government cost of changes in the soft wheat subsidy. The results show that virtually all the indirect effects come from the soft wheat market itself. The indirect effects emanating from the related markets are negligible. 相似文献

This paper focuses on macroeconomics in undergraduate agricultural economics curricula. We briefly review some of what leaders in the agricultural economics and economics professions, macroeconomics teachers, and textbook authors say about what is important, what should be taught and learned in modern undergraduate macroeconomics courses. We also report on a survey of faculty of agricultural economics departments who have responsibility for undergraduate instruction in 50 U.S. agricultural economics undergraduate programs. The surveys provide information on the current status of economics courses in their programs and the relative importance of different macroeconomic subjects to students in undergraduate agricultural economics. 相似文献

论文以2005-2009年中国工业企业数据库中水产品加工业的微观数据为样本,筛选其中7553个规模以上的水产品加工业企业样本数据进行面板分析。通过企业出口与非出口分布的统计分析,测算企业劳动生产率和全要素生产率,回归分析生产率、企业规模及地区分布等对企业产出和出口行为的影响。结果表明:生产率、企业规模、企业运营年数对出口与非出口企业的产出都有显著影响;其中,出口企业中,生产率和企业规模是决定企业出口交货值的重要影响因素,企业规模对企业出口决策选择影响显著。 相似文献

执法主体部门化、多元化是我国目前行政执法体制存在的主要问题.执法机构林立、执法职能交叉、行政处罚权分散,无疑在一定程度上削弱了行政执法的效率.上述现象在粮食行政执法监管体制上也有明显表现.认真考察粮食行政执法体制,分析存在弊端,理顺管理体制,对于完善市场经济体制、提高行政执法效率十分必要. 相似文献
