Estimation and Welfare Analysis With Large Demand Systems

We develop an approach for estimating individual or household level preferences for a large set of quality-differentiated goods and for constructing Hicksian welfare measures within the demand system framework. Our approach uses a maximum simulated likelihood procedure to recover estimates of the structural parameters and a multistage, Monte Carlo Markov chain algorithm for constructing Hicksian consumer surplus estimates. We illustrate our approach with a recreation dataset consisting of day trips to 62 Mid-Atlantic beaches.     

无套利分析在非完美条件下远期合约定价中的运用

无套利分析方法是现代金融理论的基石之一,已成为金融衍生品定价的一种重要方法,传统的金融工程教科书很少涉及非完美条件下远期合约的定价问题。在介绍无套利分析方法的基础上,通过现金流复制技术,研究了三种非完美条件下远期合约的定价问题。     

略论元诗“宗唐得古”说的理论可能——以语义学分析为线索

“宗唐得古”是元诗的基本特征之一,但这种后来的归纳与认定却被过度引申.客观史料和语义学的分析证明:元诗“宗唐得古”说的理论引申必须得到限制,它只能在“陈述”与“总结”的基础上被理解;元诗的理论口号与实践间存在巨大差异,由口号上的“宗唐”得出元诗“反宋”的引申并不能成立;元代诗风的建立在很大程度上也是一个官方“雅正”诗风建立的过程,元人自身的陈述既剖明又遮蔽了历史.     

性别与公共政策对话

进入新世纪,在中国学术领域出现了一个新的研究方向：来自不同学科领域或社会相关部门的研究者,对不同层次和不同类别的公共政策进行性别分析,提出政策建议,以进一步推进性别公平公正。本文追溯了性别与公共政策的相遇,讨论了公共政策性别分析包含的内容、性别关系与政策过程的互动,提出了对性别与公共政策这一跨学科研究领域的几点思考。

Interval estimation in discriminant analysis for large dimension

This paper is concerned with the interval estimation for the log odds of the posterior probability that the observation vector belongs to one of two homoscedastic multivariate normal distributions (Π₁ and Π₂). We give the limiting distribution of the unbiased estimator for the log odds as the sample sizes and the dimension jointly tend to infinity, and approximate the confidence interval based on the asymptotic distribution. Small-scale simulations are performed to check the precision of the approximation.     

Measuring the Influence of Unemployment Insurance on Unemployment Experiences

This article investigates the comprehensive effects of unemployment insurance (UI) policies on the amount of time and unemployment that individuals report between jobs. The econometric model jointly determines the effects of UI on the lengths of nonemployment spells, the classification of these spells as unemployment, and the likelihood of collecting program benefits. The model carefully attempts to isolate variation in UI benefits attributable to differences in generosity across programs to avoid biases in estimating policy effects induced by other contaminating sources of benefit variation. Using data on men from the National Longitudinal Survey of Youth, the empirical results find (a) UI recipients typically experience longer spells between jobs, at least up to the exhaustion of UI benefits, and report substantially larger fractions of these spells as unemployment; (b) weekly benefit amounts exert no significant influence on the likelihood of UI recipiency, on the length of spells between jobs, or on the fraction of these spells classified as unemployment; and (c) increases in weeks of UI eligibility raise the likelihood of UI collection and lengthen the number of weeks of unemployment between jobs by inducing long spells to become longer and not by altering short-duration behavior.     

A Qualitative Analysis of College Women's Leaving Processes in Abusive Relationships

Abstract

Objective: This study assessed the process of leaving an abusive dating relationship utilizing a qualitative design. Methods: Participants included 123 college women in abusive dating relationships who participated at the beginning and end of a 10-week academic quarter. Results: Qualitative content analyses were used to analyze the transcribed responses to an open-ended question about women's leaving processes over the interim period. A variety of categories and themes emerged for women in different stages of the leaving process, consistent with the Transtheoretical Model of Change and Investment Model. Data also underscored women's lack of acknowledgment, minimization, and normalization of abuse. Conclusions: These data demonstrate the importance of dating violence intervention and prevention programming on college campuses and offer information that may be useful to college health providers who assist women in abusive dating relationships.     

社会环境观在连续体文体分析中的应用——基于《高级英语》的案例分析

用韩礼德的社会环境观分析连续体文体《高级英语》，既可以加深对《高级英语》的认识，又能探索出一条区别于语言描写的连续体文体分析之路。分析过程表明：社会环境观的研究角度独特，研究结果见地深刻，且操作性强，但与语言描写法相比，其产生的结论较为宏观，故在日常的研究中，两种方法应结合起来使用，以相辅相成，互作补充。
