Ordering the largest claim amounts and ranges from two sets of heterogeneous portfolios

This paper investigates the ordering properties of the largest claim amounts and sample ranges arising from two sets of heterogeneous portfolios. First, some sufficient conditions are provided in the sense of the usual stochastic ordering to compare the largest claim amounts from two sets of independent or interdependent claims. Second, comparison results on the largest claim amounts in the sense of the reversed hazard rate and hazard rate orderings are established for two batches of heterogeneous independent claims. Finally, we present sufficient conditions to stochastically compare sample ranges from two sets of heterogeneous claims by means of the usual stochastic ordering. Some numerical examples are also given to illustrate the theoretical findings. The results established here not only extend and generalize those known in the literature, but also provide insight that will be useful to lay down the annual premiums of policyholders.

Forecasting Value-at-Risk using high frequency data: The realized range model

Current studies on financial market risk measures usually use daily returns based on GARCH type models. This paper models realized range using intraday high frequency data based on CARR framework and apply it to VaR forecasting. Kupiec LR test and dynamic quantile test are used to compare the performance of VaR forecasting of realized range model with another intraday realized volatility model and daily GARCH type models. Empirical results of Chinese Stock Indices show that realized range model performs the same with realized volatility model, which performs much better than daily models.     

论行政裁决制度的完善

行政裁决以其解决民事纠纷的专业性与技术性优势,在现代社会中的作用越来越大。由于人们对行政裁决的认识不够及制度性缺陷,行政裁决作用发挥不够理想。应在行政裁决的范围、程序、救济方式等方面完善行政裁决制度。

借鉴国际经验完善我国财政审计

财政审计是发展我国社会主义市场经济的需要，对加强财政收支管理，增强国力，防止职务腐败等都有重要意义。美国、英国、日本三个主要发达国家的财政审计比较完善，借鉴它们经验，有利于规范和完善我国财政审计，推动市场机制完善和促进经济稳定发展。     

经济学视角下人力资源供需均衡区间形成路径分析

人力资源调节成本使得人力资源供需均衡由一个“中心点”扩展成了“区间”,且这一区间的大小与调节成本的高低呈正相关关系。这不仅为政府合理地确立了人力资源供需调控所应遵循的上限和下限原则,还为如何提高人力资源供需调控的精度提供了理论依据。

Emerging Markets and Stock Market Bubbles: Nonlinear Speculation?

Daily returns of stock markets in emerging markets in Asia, Africa, South America, and Eastern Europe from the early 1990s through 2006 are analyzed for the possible presence of nonlinear speculative bubbles. The absence of these is tested for by studying residuals of vector autoregressive-based fundamentals, using the Hamilton regimeswitching model and the rescaled range analysis of Hurst. For the first test, absence of bubbles is rejected for twenty-four countries (except Mexico, Sri Lanka, and Taiwan); for the second test, it is rejected for twenty-six countries (except Malaysia). BDS testing on these residuals after autoregressive conditional heteroskedasticity (ARCH) effects are removed fails to reject further nonlinearity (except for Israel). Policy issues are discussed, noting that what is appropriate varies from country to country and time period to time period.
