摘要：This paper investigates the accumulation and distribution of retirement wealth in a dynastic model with earnings risks, longevity uncertainties, and borrowing constraints. It resolves the wealth indeterminacy problem across generations in dynastic families by introducing a transaction cost for intergenerational transfers. It captures the pattern of inter vivos transfers, the relationship between wealth and earnings, and wealth inequality in the US data. Social security lowers precautionary savings by redistributing income from families with high earnings or short-lived parents to others, thus reducing investment, the growth rate in income per capita, inequality in retirees’ consumption, and the wealth-earnings correlation.
本文研究了在一个具有收入风险、寿命不确定性和借款限制的世袭模型中的退休财富的积累和分配的问题。通过引入代际转移的交易成本，解决了世袭家庭代际之间的财富不确定性问题。该模型捕捉了美国数据中的寿命间转移模式、财富与收入之间的关系以及财富不平等。社会保障通过从高收入家庭或寿命较短的父母向其他家庭重新分配收入，降低了预防性储蓄水平，从而减少了投资、人均收入增长率、退休人员消费不平等和财富与收入的相关性。

摘要：Carbon footprint (CF) stands for a professional term is widely used in the public domain to cope with the threat posed by climate change. Nowadays the CF research was concentrated in the fields of Engineering, Environmental sciences ecology, Science technology other topics, Energy fuels, Computer science and Business economics, and there is a significant cooperative relationship between researchers, especially those with a high volume of publications. The regional layout of intercontinental CF research forces was Europe, North America, and Asia, while that between countries were the United States of America, China, England, Australia and Italy, specifically, the Chinese Academy of Sciences showed the core force of CF research with a high volume of publications and strong cooperation with international institutions. The debate and application of CF accounting method, Case Studies of CF for livestock and its products production, CF estimation for the final consumption of goods and services, Impact of human food consumption on the climate change, Application of Footprint Family for sustainable development, and CF estimation for household consumption and its drivers were the emerging CF research fronts in historical evolution. Therefore, the CF research has its own characteristics in terms of spatial and temporal layout, cooperation intensity and knowledge hierarchy, and the related topics of cross-application of agriculture and energy is becoming the potential frontier of future research.
Wiedmann and Minx 于2008年正式提出了“碳足迹”的术语定义，从过去数十年来不断增长的发表趋势来看，碳足迹已在气候变化研究议题中得到了广泛的讨论和应用，且主要以文章、会议和专利的形式分布在多个学科领域中，表现出较强的学科交叉特征。虽然碳足迹研究实力的区域布局依次为美国、中国、英国、澳大利亚和意大利，但考虑研究者之间存在的显著合作关系，中国科学院以高发文量和强国际合作程度成为碳足迹研究的核心机构。碳足迹核算方法的争议与应用、养殖业及其副产品生产的碳足迹案例、商品和服务最终消费的碳足迹估计、人类食物消费对气候变化的影响、足迹家族在可持续发展中的应用、家庭消费碳足迹估计及其驱动因素是碳足迹研究历史演进中的前沿议题。碳足迹理论是否可以成为一个指导实践行动的良好构念？我们采用了一个来自中国农产品生产的案例，试图说明碳足迹核算方法的不确定性，尤其是全生命周期评价过程潜在的不利影响。
