资金合理流动:理财目标的现实考察

本文通过对企业目标的考察,认为以企业的社会使命为企业的目标才能使企业有所发展,而要做到这一点,必须以资金合理流动作为企业财务目标,才能使企业的长久目标有可能实现。资金合理流动作为理想企业目标与现实存在的结合就成为了必然。     

When haste makes sense: Cracking down on street markets for illicit drugs

This paper presents an analytical approach to the tactical question: ‘What level of enforcement over time allows one to eliminate a street market for illicit drugs while expanding the least possible total effort?’ The analysis is done in the context of Caulkins' model [6] which predicts the rate of change of dealers as a function of enforcement level and several market parameters. Our analysis suggests that the simple strategy of using the maximum available enforcement intensity until the market has been eliminated minimizes the total enforcement effort required.     

试论生态旅游与生态补偿机制的构建

本文分析了生态旅游的特性和生态旅游的现状，并提出通过构建生态补偿机制可以改善生态旅游存在着的对生态环境的负面影响。构建生态补偿机制是使环境与经济获得动态平衡，使生态旅游获得可持续发展的重要途径。     

中国政府科技投入绩效的考察报告--基于国家级六项科技计划投入效率与问题的研究

近年来,随着世界科技进步速度的加快,提高政府科技投入越来越成为一种带有普遍性的看法。但打破原有的资金预算平衡,大幅度提高政府的科技投入存在诸多问题。所以,对于增量投入而言,能提高现有资源投入的配置效率具有更重要的意义。因此有必要对政府科技投入的总体有效性进行分析,同时,针对影响政府科技投入绩效的成因进行对策研究。     

推进企业信息化实现现代物流的"零距离"

21世纪是企业竞争的世纪，随着电子商务的迅猛发展，企业间的竞争已经演变为供应链之间的竞争，只有在推进企业信息化的基础上进行资源整合并采用零库存管理，提高物流供应链的整体效率，才能实现企业与用户的零距离，这方面“海尔”的成功给我们以有益的启示。

吡啶类与苯胺类缓蚀剂的生产及应用

以氯化苄和吡啶为原料,合成物经与其它物料复配而生产出吡啶类缓蚀剂;以苯胺和环己酮为原料,反应物经与其它物料复配而生产出苯胺类缓蚀剂。经复配后的性能评价表明:吡啶与氯化苄的反应物和甲醇1:5稀释,复配2%甲醛、3%的丙炔醇,腐蚀速度可以降到2g/m2·h以下,苯胺与环己酮的反应物和甲醇1:6稀释,复配2%左右的丙炔醇、2%左右的碘化钾,腐蚀速度可以降到7g/m2·h以下。在室内试验的基础上,通过对两类缓蚀剂进行了工业化的生产与应用,取得了良好的效果。     

Oil shocks,policy uncertainty and earnings surprises

The study utilizes a structural VAR model to understand the connections among oil shocks, policy uncertainty and aggregate earnings in US. We find that the positive innovations in US oil supply increase the aggregate earnings. A rise in the US policy uncertainty decreases the aggregate earnings. After 2007 with the shale oil development in US, the earnings responses to the US oil supply shocks has increased. Over time shocks to US oil supply reduce the policy uncertainty. The development of US oil production is associated with the increase in income and the enhancement on political and economy security in US. Policy uncertainty plays an important role in the transmission of oil shocks to the earnings. The structural oil price shocks explain around 35% of the overall variations in the policy uncertainty in the long run and cause long swings in the policy uncertainty. The direct effects of oil shocks on the aggregate earnings are amplified by the endogenous responses of policy uncertainty.     

无边界职业生涯时代不同代际员工组织承诺的影响因素

基于无边界职业生涯的理论视角,采用问卷调查法,考察了影响新生代员工和传统代员工组织承诺的关键性因素,并通过优势分析确定其相对权重.结果表明:(1)在无边界职业生涯时代,企业员工具有较高的无边界心智模式和适度的组织流动性偏好,新生代员工的无边界心智模式显著高于传统代员工,但组织流动性偏好在不同代际之间的差异不显著.(2)组织流动性偏好显著地负向预测组织承诺,无边界心智模式对组织承诺的预测作用均不显著,组织发展性支持和感知的职业机会显著地正向预测组织承诺.(3)组织承诺影响因素的相对重要性存在代际差异,组织中的职业机会是影响新生代员工组织承诺的最重要因素,组织的发展性支持是影响传统代员工组织承诺的最重要因素.     

Relevance of the disposition effect on the options market: New evidence

A moneyness‐based propensity to sell (MPS) measure, at the aggregate level, determines the propensity of option holders to exercise their winning relative to losing positions. Using data on individual stock and S&P 500 Index options, we find that the MPS measure has significant predictive power over the cross section of delta‐hedged option returns. We test the disposition effect in the options market based on a long–short strategy that exploits price distortions induced by the disposition bias. More pronounced evidence of the disposition bias is found for individual at‐the‐money call options than put options where the significance of abnormal returns remains robust across different subsamples even after we control for the portfolio option greeks and market‐based risk factors. The profitability of the long–short strategy is related to limit‐to‐arbitrage proxies suggesting that behavioral explanations help explain the positive relation between the MPS measure and delta‐hedged option returns.
