Stability, Asymmetry and Seasonality of Fund Performance: An Analysis of Australian Multi‐sector Managed Funds

Using a sample of Australian Multi-sector trusts we examine selectivity and market timing performance and extend the analysis to include the relatively new measure of volatility timing. This is of particular relevance to our data set, as high levels of volatility persistence are prevalent in Australia. In addition we consider the stability, asymmetry and seasonality of the various performance and risk measures. A survivorship adjustment procedure is also employed in order to assess the impact of survivorship on selectivity, market timing and volatility timing performance.     

How to measure mutual fund performance: economic versus statistical relevance

In the present paper a comprehensive assessment of existing mutual fund performance models is presented. Using a survivor‐bias free database of all US mutual funds, we explore the added value of introducing extra variables such as size, book‐to‐market, momentum and a bond index. In addition to that we evaluate the use of introducing time‐variation in betas and alpha. The search for the most suitable model to measure mutual fund performance will be addressed along two lines. First, we are interested in the statistical significance of adding more factors to the single factor model. Second, we focus on the economic importance of more elaborate model specifications. The added value of the present study lies both in the step‐wise process of identifying relevant factors, and the use of a rich US mutual fund database that was recently released by the Center for Research in Security Prices.     

Monetary union and the Maastricht inflation criterion: The accession countries*

We model an accession country facing a Maastricht‐type inflation criterion that specifies an inflation ceiling. In addition to deciding whether or not to satisfy this criterion, the country must decide how much costly economic reform to undertake. If the country puts enough weight on the future that it can credibly meet the inflation criterion no matter what the ceiling is, then the inflation criterion benefits the country but lowers reform. If the country puts less weight on the future, then a criterion with a properly chosen inflation ceiling can increase reform. We derive the inflation ceilings that maximize the country's welfare and its reform.     

经评审的最低投标价法的实践

随着中国建筑业管理体制改革的不断深化，招投标制度在中国得以推广应用，但目前以标底为中心的评标方法存在不足，有待完善。合理低价中标，具备不低于成本价、在合理的范围内两个条件，它代表着市场竞争的发展要求和方向，能够有效地减少一些人为因素。推进合理低价中标，应该把好资格审查关、标书评审关、招投标监督关，并要实行担保制，引入索赔机制。

区域旅游业竞争力评价:指标构建与方法选择

合理地设计评价指标和科学地评价区域旅游业竞争力,是区域间旅游业竞争力比较、现状问题分析以及制定对策建议的前提,也是区域旅游业竞争力理论的重要组成内容.本文在对现有研究回顾和评述的基础上,结合区域旅游业发展的实践和竞争力发展特征,构建区域旅游业竞争力综合评价指标体系,并对评价研究方法进行了探讨和选择.     

游客体验的模糊综合评价方法——基于宜昌市景区的问卷调查

关注游客主观体验和对景区的反馈评价,通过对宜昌市域14景区的问卷调查,获得第一手资料,并进行模糊综合评价分析.通过游客对各因子满意度和关注度的排序,揭示了旅游发展中服务环节薄弱、景区配套协调不足等问题.依据满意度与关注度将因子分类,分别提出改善策略并排列优先级,最后提出了突出景区资源禀赋优势、完善旅游支撑保障体系等建议.     

基于TOD理念的轨道交通站点更新潜力评价

在我国城市发展空间日益减少、存量用地潜力亟待挖掘的大背景下,以公共交通为导向的TOD发展模式为城市更新带来了新的动力和思路。基于TOD规划理论的原理和内涵,构建了由土地属性、交通条件和更新成本等多元因子所构成的评价指标体系;采取熵权法和层次分析法相结合的组合赋权方式用以确定指标因子的权重;利用可逼近理想解的TOPSIS法对轨道交通站点的更新潜力进行定量测算,并通过自然断点法对各站点更新潜力大小进行分级。

司法强拆运行机制可行性审视——基于案例分析的反思与重构

现行司法强拆运行机制不能有效遏制强制拆迁中恶性事件的发生,且可能导致司法强拆面临较大的运行风险,使其失去道义和法治层面的正当性支撑,导致司法强拆陷入被民众暴戾化抵制的运行困境。因此,对司法强拆运行机制的重构应当建立裁、执分离制度,保证司法强拆运行机制的公平公正;实现司法独立,避免司法受地方行政和其他外力干预;确立公众有效参与拆迁过程的制度,使司法强拆前的社会风险评估落到实处;通过司法强拆运行机制为地方政府与被拆迁户之间搭建一个有效的对话和沟通平台。
