Simulation study of confidence regions for canonical variate analysis

Canonical variate analysis often involves the construction of confidence regions round points representing group means in a 2-dimensional plot. Traditionally circles have always been constructed, but some authors have recently advocated ellipses as being more appropriate. This paper describes a Monte Carlo study investigating the effect of a range of factors on the inclusion rates of true population means within both types of region for normal data. The traditional circles do not perform too badly within a restricted range, but they are nearly always under-included. The ellipses usually have higher inclusion rates, and so are often closer to the nominal rate, but are sometimes over-included.     

建设和谐社会必须大力消除分配不公

文章从建设社会主义和谐社会的目标出发,分析了劳动收入与资本收入失衡、农民收入太低、垄断行业收入过高、权力寻租、收入差距过大等分配不公现象。阐述了收入分配不公对我国社会主义经济建设、政治建设、社会建设的严重危害。提出了大幅度提高工资水平、开征垄断税、运用税收和转移支付手段迅速缩小收入差距等消除收入分配不公的措施。

A simple monotone process with application to radiocarbon-dated depth chronologies

Summary.  We propose a new and simple continuous Markov monotone stochastic process and use it to make inference on a partially observed monotone stochastic process. The process is piecewise linear, based on additive independent gamma increments arriving in a Poisson fashion. An independent increments variation allows very simple conditional simulation of sample paths given known values of the process. We take advantage of a reparameterization involving the Tweedie distribution to provide efficient computation. The motivating problem is the establishment of a chronology for samples taken from lake sediment cores, i.e. the attribution of a set of dates to samples of the core given their depths, knowing that the age–depth relationship is monotone. The chronological information arises from radiocarbon (¹⁴C) dating at a subset of depths. We use the process to model the stochastically varying rate of sedimentation.     

中西比较视野中的分享经济理论

分享经济理论大致包括西方分享经济理论和中国公有制分享经济理论两种形态。这两种理论在思想来源、逻辑起点、基本原理和实践结果等方面存在着较大的差异。西方分享经济理论所主张的雇员和资本家共同分享利润,只是形式上分享,其实质仍然是按资分配,不可能真正实现公平的收入分享。公有制分享经济理论所倡导的净收入分成制是在社会主义公有制以及按劳分配条件下对新创造价值的分享,它可使国家、企业和职工三者结成了利益共同体,在追求共同利益的动力驱使下,发展生产,实现国家、企业和个人三者之间真正意义上的利益分享。     

论毛泽东对社会主义分配制度改革的探索

毛泽东是中国经济体制改革的最早倡导者和探索者。在社会主义分配制度方面,毛泽东曾开展过关于个人收入分配制度问题的探索,并提出重视物质利益,正确处理积累与消费的关系,兼顾国家、集体、个人三者的利益等宝贵的思想。尽管由于各方面的原因,毛泽东在这个问题上出现的反复比较多,留下了许多的遗憾。但它对十一届三中全会以后中国改革所产生的积极影响是深远的。

分配制度变革是经济制度改革的核心问题

改革本质上就是制度变迁,经济制度改革的核心是分配制度的变革,经济制度改革应该从分配制度着手,伴随分配制度的改革必然自动形成新的收入分配结构,而新的收入分配结构必然改变原有的产权结构。企业成功的关键是要建立一个合理有效的以分配制度为核心的企业运行制度,企业分配制度的有效性不仅取决于分配制度本身的先进性,还在于清晰地界定企业与政府和社会的责任。决定分配制度本身的先进性,不仅在于分配方法的合理性,而且在于各分配主体在参与分配博弈中的平等程度。
