The comparative statics of differential rents in two-sided matching markets

This paper studies how shifts in the distribution of quality on one side of the market affect earnings on the other side in a model of one-to-one matching. A more dispersed distribution of quality hurts the low ability agents on the other side because they are matched to inferior partners. Earnings being a differential rent in these markets, this pulls down the earnings of high quality agents as well. It is shown that a more dispersed ability distribution reduces total earnings on the opposite side of the market. Under some conditions, all agents on that side are hurt.      

A TEST OF THE LOCATION PARAMETER OF THE EXPONENTIAL DISTRIBUTION

In this paper, we propose a procedure for testing the location parameter of the exponential distribution for certain alternative hypotheses, which could result in the early rejection of the null hypothesis. This is a consequence of the monotone property of the test statistic which is based on the extremal quotient. The test being scale-free does not require the scale parameter to be known.     

On approximate inference for the two-parameter gamma model

In applied work, the two-parameter gamma model gives useful representations of many physical situations. It has a two dimensional sufficient statistic for the two parameters which describe shape and scale. This makes it superficially comparable to the normal model, but accurate and simple statistical inference procedures for each parameter have not been available. In this paper, the saddlepoint approximation is applied to approximate observed levels of significance of the shape parameter. An averaging method is proposed to approximate observed levels of significance of the scale parameter. These methods are extended to the two-sample case.     

Classes Inférieures de suites gaussiennes asymptotiquement indépendantes

In this paper we prove a theorem on “asymptotically independent” Gaussian sequences. This result improves and simplifies a result of Lai (1973) on lower classes of Gaussian sequences.     

Optimal site area for high-density housing development

This study provides an empirical assessment of the optimal site area for master-planned high-density housing development in Hong Kong. Conventional hedonic pricing methods are not used because they cannot separate the amenity value of large sites from the price effects caused by market power. We obtain our estimate from a unique data set containing the choice of applicants for public housing units in 128 housing estates in Hong Kong between 1990 and 1998. An inverted U-shaped relationship between site area and popularity of the estate is revealed. We conclude that the land areas of most public housing estates in Hong Kong are sub-optimal. Our estimated optimal site area serves as a quantitative benchmark for the government in its future disposal of public as well as private housing land.     

Champs aléatoires gaussiens

A limit theorem concerning quadratic variation in Gaussian random fields is established. The theorem is analogous to a result of Gladyshev (1961).     

青年职业成熟度量表的开发及其对就业的影响

开发一个科学、全面的中国青年职业成熟度测量工具,并证实其对就业的影响是有现实意义的。研究通过包括中国香港和大陆在内的三个样本对Lee(2001)的职业成熟度量表进行修订和验证。结果表明,经过修订的职业成熟度量表在信度和效度上都达到了可以接受的水平,而且职业成熟度对青年成功寻找并持续工作起到正面的影响作用。这些发现为将来研究中国青年学生职业成熟度奠定了基础。     

One country,three populations: Trust in police among migrants,villagers, and urbanites in China

While the past decade has witnessed the burgeoning of research on public assessments of the police in China, marginalized social groups have rarely been considered in this line of inquiry. Using data collected from migrant workers, rural villagers, and urban dwellers, this study assesses whether Chinese perceptions of the police are distinguishable along procedural-based trust and outcome-based trust and whether expressive concerns and instrumental concerns are predictive of trust in the police. Findings show that Chinese citizens tend to conflate procedural-based trust and outcome-based trust. Expressive concerns play a more important role than instrumental concerns, with such expressive variables as trust in neighborhood residents committee, perceived law and order, and quality of life influencing trust in the police. Public perceptions of police trustworthiness are also significantly linked to media influence. Directions for future research are discussed.     

A Cross‐Cultural Study of Adolescent Procrastination

In this study, we explore academic procrastination and associated motivation variables in 612 adolescents from Canada and Singapore. Few studies have explored adolescent procrastination and no previous studies have investigated adolescent procrastination using a cross‐cultural framework. Singaporean adolescents reported higher levels of procrastination and lower levels of self‐efficacy for self‐regulation than Canadian adolescents. Males across settings reported higher levels of procrastination and lower levels of self‐efficacy for self‐regulation than females. Bivariate relationships between procrastination and the motivation variables showed similar patterns in Singapore and Canada. Multigroup structural equation modeling revealed that self‐efficacy for self‐regulation showed the strongest multivariate relationship with procrastination for adolescents in both settings. The article concludes with implications for practitioners and researchers.
