Policy‐related implementational fluidity in subsistence marketplaces

This paper sheds light on policy‐related implementational fluidity—a context‐dependent adaptation of policies—adopted by policy implementers to address heterogeneous needs of subsistence consumer‐merchants (SCMs). In subsistence research, despite the emphasis on bottom‐up policymaking, implementational fluidity persists because of institutional and sociocultural factors that hinder policy implementers’ from effectively and accurately implementing the policies. To enrich the current bottom‐up policy process, this paper shares insights from an ethnographic study of Fijian market traders and marketplace personnel (policy implementers) and shares insights on how implementational fluidity manifests in subsistence marketplaces. Analysis reveals the interplay amongst sociohistorical context, marketplace relational dynamics and policies leading to policy adjustments and re‐negotiation by marketplace personnel and perceived injustices amongst the SCMs. The paper provides policy recommendations and practice ideas for subsistence researchers and policy practitioners to examine policy implementation gaps and the role of policy implementers in subsistence marketplaces.     

特细砂配制高流动性泵送C55预应力混凝土应用

本文通过试验分析特细砂粒径,不同材质的特细砂的基本物理材性,采用现代混凝土配合比设计理念,研究了特细砂混凝土配合比的设计原则。通过分析砂率含量、用水量、高效外加剂对特细砂高性能混凝土在工作性和力学性能上的影响,确定砂率含量的范围;通过对特细河砂和天然特细山砂混凝土性能的对比试验,结果表明细砂完全可以替代天然中粗砂配制高性能高强度、高流动性泵送混凝土。     

居民货币需求的“结构性流动陷阱”及其对我国物价变动影响之研究

由于当前经济改革中的一些结构性问题使我国居民存在对货币需求的"结构性流动陷阱"."结构性流动陷阱"是我国近年来城乡居民储蓄存款高速增长的根本原因,也是对我国自1997年以来物价变动产生重要影响的一个基本因素.文章首先对当前转型期我国存在的居民货币需求"结构性流动陷阱"形成原因进行分析,其次,依据这个观点对我国近年来出现的通货膨胀和通货紧缩的基本原因和特点进行深入的分析和系统的研究,并就我国未来短期内物价走势进行分析和预测.     

税收市场上的主体行为分析

税收竞争的场所是税收市场。税收竞争的主体 ,也是税收市场上的活动主体。政府和社会公众作为税收市场上的供给者和消费者 ,具有供给方的市场权力和要求方的市场权力。税收市场具有独占性和超额利润性 ,是两个竞争主体的博弈 ,应以建立良好的财权分权秩序 ,打破保护主义的垄断和加强民主法制建设 ,规范税收市场主体行为     

The institution efficiency of stock price limits： An experimental analysis on the two stocks market with continuous bid

Price limits in product market have been discarded in classic microeconomics. However, price limits affect the trade behavior of the same agent, since agents in the stock market change their trade status frequently. Due to the controversy on the institution effectiveness of the price limits in stock market, this paper design an experimental market with two stocks with continuous bid, in which we investigate the impact of the price limits on the stock market. The results show that the price limits moderate the price volatility within and between the trades periods, thus can stabilize stock price. In addition, price limits, when measured by traditional approach, restrain the fluidity of the market, reduce the volatility of transaction shares and maintain durative of fluidity. While volatility-based fluidity measurements show that the fluidity is enhanced significantly in stock market with price limits.     

Retail formations: tracing the fluid forms of an online retailer

ABSTRACT

Change has often been said to characterise retailing, and research on retail change is extensive. However, though much of that research has focused on retail formats, it has not sufficiently addressed the fluid nature of retailing and how its formats emerge. This paper offers a more dynamic conceptualisation of retail format change by introducing the concept of retail formation. Taking a constructivist market studies approach and drawing upon an ethnographic study of a Swedish consumer electronics retailer, the paper shows how retail formations are continually being made in a dynamic process that can be initiated by various actors, does not necessarily follow a logical order, and commonly produces unexpected results. The concept of retail formation allows us to better understand the increasing fluidity of retailing enabling us to trace complex market processes, examine multiple actors simultaneously, and taking into account the socio-historical and socio-cultural dynamics involved in shaping retail markets.     

买卖型担保中流质条款效力的证成与强化

审判实践不应僵化地援引禁止流质规则来无效化买卖型担保中的流质条款，以避免将买卖型担保重新装回典型担保的制度牢笼。禁止流质规则作为强制性预防措施有一定的合理性，在其立法目的必要性日渐丧失的情况下，扩张解释或者类推适用禁止流质规则均不可取，买卖型担保中的流质条款合法有效。对债权人课以清算义务，能够强化流质条款的正当性，从而彻底扫清买卖型担保中流质条款有效化的伦理障碍。担保人应负初步举证责任，只有价值差额超过“24%年利率上限”时才能启动清算，以确保流质条款的效率优势。尽管流质条款与以物抵债具有相似性，但不得以禁止流质规则束缚非买卖型担保中的以物抵债。     

上海燃料油期货市场流动性检验

本文在对上海燃料油期货的流动性进行数量分析和检验后,阐明了燃料油期货的成功运行对未来建立境内石油期货市场具有极大的推动作用。燃料油是原油炼制出的成品油中的一种重油,我国燃料油市场流动性较高,表明我国燃料油期货交投活跃,交易效率较高,对未来石油期货的成功运行积累了宝贵经验。     

基于要素流动成本的区域经济发展环境与经济发展关系

"良好的经济发展环境可以促进区域经济的快速发展"作为一个命题已被普遍接受.然而,以往文献对经济发展环境促进区域经济发展的深层原因却没有给出很好的解释.文章提出要素流动成本的概念,通过构建基于要素流动成本的区域经济发展环境与经济发展运行机制和模型来研究二者关系.结论指出优化经济发展环境本质上就是要降低要素流动成本及其变动率,关键手段就是进行创新.     

卖空交易机制对我国上证A股流动性的影响——以融券为例

2010年3月31日中国正式推出了融资融券,标志着中国自此有了卖空交易机制,对中国股票市场来说有划时代的意义。因此,研究卖空交易机制对股票市场的影响有极大的现实意义。本文利用上证A股市场的数据来实证研究卖空交易机制与市场流动性间的内在关系。研究表明,卖空交易机制推出后,市场流动性并没有增加,Granger因果检验结果证实市场流动性的增加不是由融券交易引起的。最后本文从市场、管理层、券商和投资者四个方面分析了产生此实证结果的原因。
