Risk Perception and Information Processing: The Development and Validation of a Questionnaire to Assess Self‐Reported Information Processing

The role of information processing in understanding people's responses to risk information has recently received substantial attention. One limitation of this research concerns the unavailability of a validated questionnaire of information processing. This article presents two studies in which we describe the development and validation of the Information‐Processing Questionnaire to meet that need. Study 1 describes the development and initial validation of the questionnaire. Participants were randomized to either a systematic processing or a heuristic processing condition after which they completed a manipulation check and the initial 15‐item questionnaire and again two weeks later. The questionnaire was subjected to factor reliability and validity analyses on both measurement times for purposes of cross‐validation of the results. A two‐factor solution was observed representing a systematic processing and a heuristic processing subscale. The resulting scale showed good reliability and validity, with the systematic condition scoring significantly higher on the systematic subscale and the heuristic processing condition significantly higher on the heuristic subscale. Study 2 sought to further validate the questionnaire in a field study. Results of the second study corresponded with those of Study 1 and provided further evidence of the validity of the Information‐Processing Questionnaire. The availability of this information‐processing scale will be a valuable asset for future research and may provide researchers with new research opportunities.

Conditional VAR and Expected Shortfall: A New Functional Approach

We estimate two well-known risk measures, the value-at-risk (VAR) and the expected shortfall, conditionally to a functional variable (i.e., a random variable valued in some semi(pseudo)-metric space). We use nonparametric kernel estimation for constructing estimators of these quantities, under general dependence conditions. Theoretical properties are stated whereas practical aspects are illustrated on simulated data: nonlinear functional and GARCH(1,1) models. Some ideas on bandwidth selection using bootstrap are introduced. Finally, an empirical example is given through data of the S&P 500 time series.     

Factor screening in nonregular two-level designs based on projection-based variable selection

In this paper, we focus on the problem of factor screening in nonregular two-level designs through gradually reducing the number of possible sets of active factors. We are particularly concerned with situations when three or four factors are active. Our proposed method works through examining fits of projection models, where variable selection techniques are used to reduce the number of terms. To examine the reliability of the methods in combination with such techniques, a panel of models consisting of three or four active factors with data generated from the 12-run and the 20-run Plackett–Burman (PB) design is used. The dependence of the procedure on the amount of noise, the number of active factors and the number of experimental factors is also investigated. For designs with few runs such as the 12-run PB design, variable selection should be done with care and default procedures in computer software may not be reliable to which we suggest improvements. A real example is included to show how we propose factor screening can be done in practice.

巨额财产来源不明罪相关问题研究

2009年2月28日通过的《中华人民共和国刑法修正案（七）》（以下简称《刑法修正案（七）》）第十四项对《中华人民共和国刑法》第三百九十五条有关巨额财产来源不明罪的规定作了修改。然而,对于巨额财产来源不明罪相关问题的讨论并没有随着《刑法修正案（七）》的颁布而停止。为了进一步深化对巨额财产来源不明罪的认识,对《刑法修正案（七）》中巨额财产来源不明罪的相关规定加以探讨,以期对巨额财产来源不明罪的进一步完善能有所裨益。     

“保险性质”期权定价模型及其应用研究

针对传统期权风险大的特点，以欧式看涨期权为基础提出一种风险小、价格低的特殊期权——“资产保险性质”期权，即期权买者出于对标的资产的保险目的，签订期权合约后，若标的资产价格上涨，期权买者将其一部分收益支付给期权卖者，以这种交易方式对传统期权产品进行改进并重新定价，从而得出“保险性质”期权及其定价公式。针对和传统期权的价格变动状况，用Excel进行了模拟比较，证明了“保险性质”期权价格低（吸引期权买者）、风险小（利于期权卖者的风险控制）的特点。“保险性质”期权产品的开发将对我国各类金融市场的建设具有现实意义。

Robust nonparametric estimation with missing data

In this paper, under a nonparametric regression model, we introduce two families of robust procedures to estimate the regression function when missing data occur in the response. The first proposal is based on a local M$M$-functional applied to the conditional distribution function estimate adapted to the presence of missing data. The second proposal imputes the missing responses using the local M$M$-smoother based on the observed sample and then estimates the regression function with the completed sample. We show that the robust procedures considered are consistent and asymptotically normally distributed. A robust procedure to select the smoothing parameter is also discussed.
