Spatial Statistics and Real Estate   总被引:9,自引:2,他引:7  
Real estate has historically employed statistical tools designed for independent observations while simultaneously noting the violation of these assumptions in the form of clustering of same sign residuals by neighborhood, along roads, and near facilities such as airports. Spatial statistics takes these dependencies into account to provide more realistic inference (OLS has biased standard errors), better prediction, and more efficient parameter estimation. This article provides an overview of the field and directs readers to the relevant literature and software.  相似文献

In this article different spatial statistics techniques to analyze the behavior of used dwelling market prices are compared. We fit two lattice models: simultaneous and conditional autoregressive, a geostatistical model, the so-called universal kriging and finally, a linear mixed-effect model. Different spatial neighborhood structures are considered, as well as different spatial weight matrices and covariance models. The results are illustrated through a real data set of 293 properties from Pamplona, Spain.  相似文献

我国商业银行前瞻性资本结构模型构建与实证研究   总被引:2,自引:1,他引:1  
资本结构研究对以建立现代金融企业为目标的中国银行业十分重要。本文通过深入分析资本充足率、核心资本充足率、股权回报率和平均融资成本之间的关系,提出我国商业银行在转轨时期的前瞻性资本结构模型,并以我国四大国有商业银行为例进行实证分析,进而得到资本结构管理的指标矩阵。这有利于合理确定银行的资本结构,满足投资者的股权回报要求,降低融资成本。国内其他类型的商业银行也可以通过改变参数的方式,以前瞻性资本结构模型建立适应各自规模和定位的估计区间。  相似文献

场外市场会计盈余的信息含量   总被引:1,自引:0,他引:1  
以万德数据库提供的新三板企业为样本,检验场外主体市场的会计盈余信息含量。混合样本检验显示,盈余信息披露对投资者超额收益有显著影响。分期检验中,2009年披露的盈余信息还不具备有效的信息含量;2010年披露的盈余信息具有信息含量,可能预示着场外市场的完善和成熟。此外,样本检验结果没有找到场外市场具有半强势有效的证据,但可以推断该市场处于弱势有效状态。  相似文献

基于资本充足率要求的我国商业银行风险控制有效性研究   总被引:1,自引:0,他引:1  
资本充足率作为《巴塞尔协议》的重要组成部分,一直以来就是各国商业银行监管工作的重点,2008年全球金融危机的爆发更是将更多的目光吸引至此。应用面板数据模型测度我国资本充足率要求对商业银行风险控制有效性的实证研究结果表明,我国商业银行资本充足率的限制具有降低银行外部风险、增强商业银行内部稳定性的功能。应建立一种显性的存款保险制度来规范我国商业银行的救助机制,与资本充足率监管一起形成维护我国商业银行稳定的"安全网"。  相似文献

Continuous-time affine models have been recently introducedin the theoretical financial literature on credit risk. Theyprovide a coherent modeling, rather easy to implement, but havenot yet encountered the expected success among practitionersand regulators. This is likely due to a lack of flexibilityof these models, which often implied poor fit, especially comparedto more ad hoc approaches proposed by the industry. The aimof this article is to explain that this lack of flexibilityis mainly due to the continuous-time assumption. We developa discrete-time affine analysis of credit risk, explain howdifferent types of factors can be introduced to capture separatelythe term structure of default correlation, default heterogeneity,correlation between default, and loss-given-default; we alsoexplain why the factor dynamics are less constrained in discretetime and are able to reproduce complicated cycle effects. Thesemodels are finally used to derive a credit-VaR and various decompositionsof the spreads for corporate bonds or first-to-default basket.  相似文献

The study of participation in the budgetary cycle has formed a prominent part of the research literature concerned with the budgetary process. More recently there has emerged a body of literature concerned with exploring the political and symbolic nature of the budgetary process. The paper reports upon the outcomes of an empirical study of the introduction of `budgetary participation' in a division of a European subsidiary of a large North American car manufacturer. We detail the long process of consultation and negotiation within the subsidiary, and between it and the European Headquarters. The study provides a revealing instance of the roles of formal budget participation as a ritual of control and legitimation without the substantive involvement of middle managers and suggested to us the introduction of de-coupling and organizational hypocrisy alongside the introduction of budget participation. The study pays close attention to the contingent effects of the wider political context of the division and the relationships between the division, its organizational context and organizational environment, and how this context played upon the budgetary process in the division. The outcomes that we analyse at `Delta' reflect the de-coupling strategies and organizational hypocrisies commonly found in public sector organizations. In this wider setting the corporation persists with the ritual of `tight' budget negotiation and target setting and apparent underachievement in performance. Yet we conclude that the complex technological and political context to the formation and siting of Delta continued and may continue to support its existence.$g0  相似文献

Marius Berliet, a pioneer of the car industry, was one of the first to introduce Taylorism in France. He wanted to implement standard costing techniques in his company at the very same time they were conceived in the USA, around the time of the First World War. Given that this technique was to become popular in France only during the 1950s, this article seeks to understand the reasons which prevented it from being applied at Berliet's company forty years earlier. One obvious explanation is the burden of the cost accounting methods which prevailed in France until 1950. The paper also considers the hypothesis of a lack of interest, and skill by those who could have promoted this new technique, especially managers and engineers.  相似文献
