现代企业组织结构优化分析

我国企业曾经是“技术落后,管理更落后”。随着知识经济时代的推进,管理的艺术性大大增强,致使计划、组织和控制职能呈现出更大的灵活性。这种灵活性的本质就是市场适应性在管理工作中的“映射”。计划工作的首要任务就是确定企业经营战略;组织工作的首要任务就是在经...     

Recovering Risky Technologies Using the Almost Ideal Demand System: An Application to U.S. Banking

We present and estimate a model that shifts the focus of modeling production from the traditional assumptions of profit maximization and cost minimization to a more general assumption of managerial utility maximization that can incorporate risk incentives into the analysis of production and recover value-maximizing technologies. We implement the model using the almost ideal demand system. In addition, we use the model to measure efficiency in a more general way that can incorporate a concern for the market value of firms assets and equity and identify value-maximizing firms. This shift in focus bridges the gap between the risk incentives literature in banking that ignores the microeconomics of production and the production literature that ignores the relationship between production decisions and risk. Our estimation of the model for a sample of U.S. commercial banks illustrates that results obtained from our generalized model can differ significantly from those obtained from the standard profit-maximization model, which ignores risk.     

我国城乡一体化改革的法制保障

在我国, "城乡一体化"观念大约出现于20世纪80年代末.对于什么是城乡一体化,不同学科有不同界定.法学视角中的城乡一体化是指通过制度变革和渐进过程,打破并最终消除城乡二元结构的壁垒,使农村与城市获得平等的发展机会,使农民与市民享有平等权利,享受平等的物质文明、政治文明和精神文明.     

Generalized linear mixed models with informative dropouts and missing covariates

Generalized linear mixed models (GLMM) are useful in many longitudinal data analyses. In the presence of informative dropouts and missing covariates, however, standard complete-data methods may not be applicable. In this article, we consider a likelihood method and an approximate method for GLMM with informative dropouts and missing covariates. The methods are implemented by Monte–Carlo EM algorithms combined with Gibbs sampler. The approximate method may lead to inconsistent estimators but is computationally more efficient than the likelihood method. The two methods are evaluated via a simulation study for longitudinal binary data, and appear to perform reasonably well. A dataset on mental distress is analyzed in details.
