企业文化是企业的生命

毛泽东指出：“没有文化的军队是愚蠢的军队，而愚蠢的军队是不能战胜敌人的。”著名民营企业集团——四通公司总裁段永基套用毛泽东的这段话说：“没有文化的企业是庸俗的企业。”而笔者想说，没有文化的企业是没有生命的企业。回顾20年来民企大起大落的发展历程，许多经营成功的企业皆因文化失败而最终走向没落。     

Intraday Lead-Lag Relationships Between the Futures-, Options and Stock Market

In rational, efficiently functioning and complete markets, returns on derivative and underlying securities should be perfectly contemporaneously correlated. Due to market imperfections, one of these markets may reflect information faster. The use of high-frequency data and the choice for a small unit time interval to measure these lead-lag relations comes at the cost of some or many missing observations, causing traditional estimators to either under- or overestimate covariances and correlations. We use a new estimator to estimate lead-lag relationships between the cash AEX index, options and futures. We find that futures returns lead both options and cash index returns by approximately 10 minutes. The relationship between options and the cash market is not completely unidirectional.     

Negotiation support using the Graph Model for Conflict Resolution

The Graph Model for Conflict Resolution is a flexible methodology for systematically studying strategic conflicts in the real world, and is therefore a natural tool for negotiation support. The basic definitions underlying the graph model are reviewed, and the techniques for analysis and interpretation are discussed. The modeling and analysis of a case study, an international trade negotiation concerning the export of Canadian softwood lumber to the United States, are used to demonstrate the practical application of the Graph Model for Conflict Resolution as a negotiation support tool. The modeling and analysis is carried out using the GMCR software system. The ability of the Graph Model for Conflict Resolution to provide insights and advice to negotiators is emphasized.     

Programme Evaluation with Unobserved Heterogeneity and Selective Implementation: The Mexican PROGRESA Impact on Child Nutrition

This paper considers the impact of Programa de Educación, Salud y Alimentación ( PROGRESA ), a large Mexican rural anti-poverty programme that had an evaluation sample in which overall treatment was randomly assigned to some communities but not others, on child nutrition. When we examine the impact of PROGRESA based on the presumption of randomized allocations, we find that PROGRESA had no or even a negative impact on child nutrition. However, not all children designated to receive nutritional supplements actually did so. Our preferred estimates – child fixed-effects estimates that control for unobserved heterogeneity that is correlated with access to the supplement – indicate a significantly positive and fairly substantial programme effect of the nutritional supplements on children 12–36 months. They imply an increase of about a sixth in mean growth per year for these children and a lower probability of stunting. Effects are somewhat larger for children from poorer communities but whose mothers are functionally literate. The long-term consequences of these improvements are non-trivial; its impact working through adult height alone could result in a 2.9% increase in lifetime earnings.     

鹿溪河漂流

“岸芷汀兰,郁郁青青……”．当我乘橡皮艇漂流在成都近郊鹿溪河上的时候,范仲淹的此句名言便一再地从我的脑海中欢快地蹦跳出来。此时正是初夏的五月．明丽的阳光透过两岸浓郁的林木,哗啦啦地照射在或急或缓的河流上,这条成都境内的岷江二级支流所凸现的波光粼粼,美仑美奂,着实让人心醉:散发着亲切泥土气息的河水涌动两岸倒     

发展中国远期外汇品种的优先次序

中国人民银行宣布自2005年7月21日起中国开始实行以市场供求为基础、参考一篮子货币进行调节、有管理的浮动汇率制度。这是中国在汇率形成机制市场化改革进程中迈出的重要的关键一步,这表明人民币汇率的变动将更加灵活、具有弹性。此后不久,央行在8月10日推出促进银行间外汇市场发展的重大举措,其中包括扩大即期外汇市场交易主体、允许开办银行间远期外汇交易、并允许符合资格的市场会员开展人民币掉期交易等。这意味着,在新的汇率制度下,政府正加快发展完善远期外汇市场的步伐,从而为市场主体提供更充分、有效的避险工具,避免汇率变动对实…

研究"后过渡期"特点促进中国经济稳定发展

入世后3年,中国的国民经济始终保持着平稳快速增长,对世界经济的影响力也在不断增强.2004年底到2006年底是中国入世的后过渡期.能否准确认识和把握后过渡期特点,能否从更大范围和更宽视野统筹国内发展和对外开放,能否充分运用WTO规则以趋利避害,提高应对市场开放冲击的有效性,关系中国能否顺利度过后过渡期,关系中国经济的长期繁荣稳定.
