外汇占款对我国经济增长的影响--基于货币政策传导机制的VAR实证分析

文章通过对1994-2011年外汇占款的情况进行定性和定量分析,采用向量自回归模型,进行脉冲响应分析和方差分解。得出结论：外汇占款对我国基础货币、货币供应量和信贷总量都有扩张的影响,在间接融资依旧是当前我国企业融资的主要方式的情况下,外汇占款可以通过影响基础货币的投放来影响货币供应量和信贷总量,最终促进国内生产总值的上升。同时,由于外汇占款在基础货币中的比重不断上升,将削弱中央银行通过公开市场操作来回收流通中不断上升的货币的作用,由此会引起外部经济中资本账户和经常项目的“双顺差”给国内货币政策带来的巨大影响,对中央银行的货币政策效果产生重大影响。     

限购令效力困惑与破解：溯及力与不可抗力的适用

限购令不具有溯及力,限购令会因合同对外缺乏公示性被轻易规避,导致限购令形同虚设,不仅房价继续非理性上涨,而且使限购令保护公共利益的目的落空。反之,限购具有溯及力,购房合同当事人基于当时授益性的法律规定,依法享有的合同信赖利益无法实现。为了兼顾公共利益和个人利益合理保护,限购令对其生效前不具有公示性的合同具有溯及力,但限购令溯及既往并非导致合同无效,而是构成合同履行障碍。购房合同履行障碍的破解途径：合同或协议解除,或部分履行,或以后继续履行。     

Dial 'M' for Metonym: Universal Exports,M's Office Space and Empire

For James Bond, Britishness is most often realised outside the British Isles, within the old Empire. Whenever physically located in Britain proper, he is most likely to be found in the offices of Universal Exports otherwise known as the British Secret Service. M's office is a metonym for England, a stable point of departure for Bond's adventures, and a site from which to theorise the relationship between M (England) and Bond (Britain); ideology, iconography and office fittings; changes and challenges to that 'office space'; cognitive mapping and the resonance of a British signifier on the margins of empire.     

Predicting Material Hardship Among Former Welfare-to-Work Participants: An Income- and Resource-Packaging Model

ABSTRACT

Material hardship is of concern because it refers to physical deprivation related to meeting the basic needs of food, housing, utilities, and other items. This study tests a predictive income- and resource-packaging model of material hardship using survey data collected from 459 former welfare-to-work program participants. Logistic regression results show that receiving social support in the form of living rent-free decreased the odds for experiencing material hardship. The predictors of working in the informal economy, being sanctioned while on public assistance, having mental health issues, and having transportation problems all increased the odds for experiencing material hardship. The measures of formal employment income, Temporary Assistance for Needy Families income, work-first program participation, sharing living expenses, monetary social support, and assistance from nonprofit organizations were unrelated to predicting material hardship experiences. Policymakers interested in improving conditions for needy families should question the use of sanctions and carefully monitor material hardship among those sanctioned. Future programs and future research should consider the extent to which low-income women participate in the informal economy to make ends meet, rely on social networks to live rent-free, and struggle with poor health and transportation problems.     

C2C 环境中顾客重复购买行为的实证与建模

通过分析C2C 商家的交易记录, 发现单个商家的顾客重复购买次数呈幂律分布, 这与重复购买理论以往得到的购买次数为负二项分布的结论不同. 基于C2C 交易的实际情况, 建立了具有购买强化效应的购买概率模型, 模型很好的解释了顾客重复购买率呈幂律分布的现象.实证和模型表明, C2C 环境中, 顾客购买次数的分布具有很长的尾部, 大量顾客有低的购买次数, 而少数顾客有很高的重复购买次数;模型还揭示了巨大的潜在顾客数量和顾客多次购买的强化效应是造成重复购买分布呈幂律形式的重要原因.     

危机考验法治——评限购令遭遇的合宪性与合法性困境

国务院及其办公厅发布的限购令虽然旨在化解房市风险、保障民生,但是违反了《宪法》、《物权法》、《行政许可法》等多部法律以及行政法的基本原则。为了化解限购令遭遇的合宪性与合法性困局,调控部门应当做到以下几点:从依政策调控走向依法调控;按照宪法和监督法的要求纠正某些违反宪法和法律的调控措施;对重要的限购措施应通过听证等形式吸收公众意见。

宪法物质帮助权的理论建构

物质帮助权被大多数国家确立为公民的一项宪法权利,它是指公民享有的获得国家生存保障的权利。物质帮助权是社会保障制度的本源.物质帮助权理论的建立和完善对于从宪法层面指导我国社会保障制度的发展具有深远意义,有助于维护社会弱势群体利益,实现社会公平正义。     

城镇廉租住房政策两类配租方式的经济学分析

实物配租和租金配租是城镇廉租住房政策实施过程中主要的两类配租方式。通过经济学方式,从消费者效用和市场供求关系两个维度分别对其进行分析,得出在市场低档存量房短缺的情形下,实物配租优于租金配租的结论。在此基础上提出几方面政策建议,短期内以增加市场上廉租住房的存量,增大实物配租的覆盖面为主,结合提高租金配租的保障水平,消除两种配租形式之间存在的待遇不公现象,继而逐步转变为以租金配租为主、实物配租为辅的配租模式。     

水稻价格保护制度:历史演变、现实困境与政策建议

2010年我国粮食总产量实现了"七连增",然而粮食依然处于供求紧平衡的状态,水稻作为我国首要的粮食作物,是老百姓最重要口粮之一,研究如何通过价格的手段保证水稻增产、稻农增收意义重大。在全面回顾和总结我国水稻价格保护制度演变历程的基础上,认为:现行价格保护存在收购价格水平偏低、收购价格范围偏小、收购价格时间偏短、收购主体偏少等问题;建议提高水稻保护价格,扩大稻谷最低收购价格政策区域,延长稻谷最低收购价格政策实施的时间,构建多元稻谷储备主体,将稻谷价格保护制度法制化以及构建稻谷目标价格制度等。
