风险投资家的双重逆向选择风险规避机制

风险投资过程中,由于信息的不对称,投资者与风险投资家之间、风险投资家与风险企业家之间存在着双重逆向选择风险。在融资阶段的信号传递机制中,作为代理人的风险投资家,选择融资计划书信号,向作为委托人的投资者传递其能力信号,投资者据此修正自己的先验概率,然后根据后验概率,与风险投资家签定合同规避风险;在投资阶段的信息甄别机制中,作为中间委托人的风险投资家先提供合同,这时唯一可能是分离均衡,即不同类型的风险企业家选择不同的合同规避风险。     

资产证券化交易过程中的会计和税务问题探讨

资产证券化是世界上最先进的金融工具之一。就目前我国来讲 ,资产证券化的发展还处于起步阶段 ,缺乏实践经验 ,因此在会计和税务制度等方面尚难以对资产证券化形成支持 ,这将成为我国开展资产证券化的障碍。在借鉴发达国家运用证券化融资的成功经验的基础上 ,着重讨论了资产证券化过程中的会计和税务问题 ,并结合资产证券化本身的特性 ,提出了相应的解决建议     

论《红楼梦》“十二金钗“的入选与序次

排座论次是中国古典小说的一种重要文化现象。“十二金钗”的入选 ,基于封建末世大家族的各种悲剧类型 ,但又着重强调了“十二金钗”的门第和出身 ,“十二金钗”的序列先后又体现了曹雪芹的爱憎情感和道德评价。通过对《红楼梦》“十二金钗”的入选和序次的考察 ,有助于我们加深对曹雪芹思想及创作心态的理解

从战略高度切实加强对领导干部的主动监督

本文主要观点是:建立选拔任用干部的监督机制是我国目前亟需解决的重要问题,它关系到是否能将有中国特色的社会主义事业不断推向前关键不是出了问题以后的解决方法,而是要加强对干部的主动监督,防止干部腐败变质.千秋大业在于用人,在选拔干部时应遵循已制定的科学规范,并从几方面加强监督,在工作中不断完善监督机制,同时要强调对干部的教育培训,并将其作为实施监督的基础性工作.     

SHOULD WE ESTIMATE THE PROBABILITY OF CORRECT SELECTION?

Various authors, given k location parameters, have considered lower confidence bounds on (standardized) dserences between the largest and each of the other k - 1 parameters. They have then used these bounds to put lower confidence bounds on the probability of correct selection (PCS) in the same experiment (as was used for finding the lower bounds on differences). It is pointed out that this is an inappropriate inference procedure. Moreover, if the PCS refers to some later experiment it is shown that if a non-trivial confidence bound is possible then it is already possible to conclude, with greater confidence, that correct selection has occurred in the first experiment. The short answer to the question in the title is therefore ‘No’, but this should be qualified in the case of a Bayesian analysis.     

An alternative to model selection in ordinary regression

The weaknesses of established model selection procedures based on hypothesis testing and similar criteria are discussed and an alternative based on synthetic (composite) estimation is proposed. It is developed for the problem of prediction in ordinary regression and its properties are explored by simulations for the simple regression. Extensions to a general setting are described and an example with multiple regression is analysed. Arguments are presented against using a selected model for any inferences.

THE SOCIAL IMPACT OF BROADBAND HOUSEHOLD INTERNET ACCESS

Broadband changes everything. Or so we are told. But does it? There is only one way to find out - follow people who move from narrowband to broadband internet access and see what changes. This paper reports exactly this kind of analysis using data from a two wave European panel study (e-Living) and the lagged endogenous regression approach to see if switching to broadband increases the time spent online, the use of online communication services, the breadth of internet activities and the amount of online spend, and whether it decreases the time spent watching TV and the level of social leisure activities. The results suggest, in the main, that switching to broadband made little difference for this group of early broadband adopters who were already heavy internet users. There was no evidence of an online spend or social leisure substitution effect although there was evidence of a reduction in time spent watching television, and an increase in email in use, time spent online and breadth of internet use. In all cases however it was the previous levels of behaviour that were the most significant and switching to broadband was, in general, one of the least strong effects.
