On an optimal consumption problem for p-integrable consumption plans

A generalization is presented of the existence results for an optimal consumption problem of Aumann and Perles [4] and Cox and Huang [10]. In addition, we present a very general optimality principle. Received: July 14, 1999; revised version: September 9, 1999     

两型社会建设中建设用地集约利用问题探讨——以长株潭城市群为分析对象

集约利用建设用地是长株潭土地资源利用机制创新的关键。长株潭城市群应以交通建设为契机,推广人车人流节地模式、开发园区土地集约模式等成功做法,建立节约集约利用建设土地约束机制,加强建设用地控制标准建设评价工作和相关配套制度建设和改革,推动长株潭城市群建设用地的集约利用。     

对经济衰退阴影下蓝色壁垒问题的理性审视

在全球经济衰退的阴影下,贸易保护主义抬头的可能性正在增强,新的贸易冲突难以避免,以SA8000为代表的蓝色壁垒将成为贸易保护主义信手拈来的武器。本文认为我国客观存在劳工权益受到侵犯的问题,我国劳工并未获得与"中国制造"同步增长的权益;在经济衰退的威胁下,我国以劳动密集型产品为主的出口企业面对的不仅仅是订单减少的问题,更要面对新的贸易壁垒——蓝色壁垒,因此应抓住当前机遇,化"危"为"机",促进对外贸易的持续健康发展。     

我国企业景气调查的特点、问题和对策

企业景气指数和企业家信心指数是用于观测和分析宏观经济运行、企业生产经营所处的状态以及未来发展变化趋势,这些越来越为人们所重视.我国企业景气调查进一步发展的对策是:完善报表制度;保证样本单位相对稳定;改进企业景气调查的实施工作;加强基础数据的收集与整理;与统计预测方法相结合;建立景气指数预测与决策信息支持系统.     

Does conglomeration really reduce credit risk?

I quantify the effects of conglomeration on credit risk by first computing theoretical default probabilities for conglomerates and their hypothetical stand‐alone counterparts and then mapping them into physical probabilities using a comprehensive database of corporate failures. Comparing the credit risk of conglomerates with that of hypothetical stand‐alone firms, I report significant reductions in the annual probability of default for small firms. My results support the proposition that managers can have a strong incentive to engage in conglomeration, even if it reduces shareholder value and show for which firms this is the case.

Hypothesis testing and parameter estimation based onM-statistics ink samples with unequal variances

Summary Ink samples with unequal variances,M-tests for homogeneity ofk location parameters are proposed. The asymptoticχ ²-distributions of the test statistics and the robustness of the tests are investigated. NextM-estimators (ME’s) of parameters are discussed. Furthermore positive-part shrinkage versions (PSME’s) of theM-estimators for the location parameters are considered along with modified James-Stein estimation rule. In asymptotic distributional risks based on a special feasible loss, it is shown that the PSME’s dominate the ME’s, and preliminary test and shrinkageM-versions fork≧4.
