The Economics and Bioeconomics of Folk and Scientific Classification

Synopsis This paper is the product of a collaboration between a biologist (Ghiselin 1997) who works on the philosophy of classification and an economist (Landa 1981, 1994) who works on the ‘Economics of Identity’: how and why people classify people based on identity in the context of a theory of ethnic trading networks. In developing the ‘bioeconomics’ (the synthesis of economics with biology) of classification, we crossed a number of disciplinary boundaries—anthropology, economics, sociology, biology, and cognitive psychology including evolutionary psychology’s ‘fast and frugal’ heuristics. Using a bioeconomics approach, we argue that folk classifications—the classifications used by ordinary persons—have much in common with scientific classifications: underlying both is the need for economy of information processing in the brain, for the efficient organization of knowledge, and for efficiency of information acquisition and transmission of information to others. Both evolve as a result of trial and error, but in science there is relatively more foresight, understanding, and planning.

SAN技术在大型网络存储中的优势分析

针对大型网络对高性能存储的要求,文章提出一种基于SAN技术解决大型网络存储系统的实现方案.由于SAN采用了高速的光纤技术,大大提高了数据传输速度,并且在整个结构中做到了服务器与存储系统之间的真正隔离.结果表明应用了SAN网络存储系统的大型网络,在数据存储上的各项指标都有一定的提高.     

商业贿赂的成因探析与对策建议

当前商业贿赂已经成为典型的商业惯例，破坏了公平竞争和正常交易秩序，危害很大。市场竞争存在缺陷、专门立法缺失、刑法有关罪名存在不足、执法主体分散和执法手段单一等问题是我国商业贿赂形成的主要原因。法律方面存在的缺失，使打击商业贿赂行为难以奏效。对此，应采取建立举报人制度、加大经济处罚、继续推行阳光工程、加强单行反商业贿赂立法、修改刑法相关条款、重点打击单位贿赂等措施，遏制商业贿赂。     

中国非加速通货膨胀失业率研究

非加速通货膨胀失业率不仅是一个失业理论,也是整个宏观经济分析中的一个重要概念,它对于宏观经济政策尤其是货币政策的制定具有重要指示作用.本文研究了1978年-2004年间的我国非加速通货膨胀率,对TV-NAIRU序列的HP滤波检验与Gardon模型分析说明了我国NAIRU具有相同的变化趋势,且两种模型的结果均表明目前我国实际失业率低于NAIRU,经济形势存在通货膨胀的压力.     

股票市场收益率波动长记忆性的分解及实证研究

目前股票市场长记忆性检验和建模方法，不能很好地消除短期记忆的影响，针对这一问题，本文提出寻找序列的突变点，通过将序列分解为只包含长记忆性部分和不包含长记忆性部分的序列分解技术，来排除短期记忆的影响。对上证指数和深圳成分指数收益率波动的长记忆性进行实证研究发现，将序列分解以后进行长记忆性检验，不仅可以得出长记忆性检验更为精确的结论，同时可以检验序列分解过程的效果。     

Revisiting managerial perspectives on dividend policy

We survey managers of Nasdaq firms that consistently pay cash dividends to determine their views about dividend policy, the relationship between dividend policy and value, and four common explanations for paying dividends. The evidence shows that managers stress the importance of maintaining dividend continuity and widely agree that changes in dividends affect firm value. Managers give the strongest support to a signaling explanation for paying dividends, weak to little support for the tax-preference and agency cost explanations, and no support to the bird-in-the-hand explanation. The study provides new evidence about how managers view dividend life cycles and residual dividend policy. The authors would like to thank two anonymous referees for helpful comments and suggestions, and Maheshan Fernando and Sumeet Chawla for providing research assistance.     

Characterizations of distributions via linearity of regression of generalized order statistics

Let X (r, n, m, k), 1 r n, denote generalized order statistics based on an absolutely continuous distribution function F. We characterize all distribution functions F for which the following linearity of regression holds E(X(r+l,n,m,k) | X(r,n,m,k))=aX(r,n,m,k)+b.We show that only exponential, Pareto and power distributions satisfy this equation. Using this result one can obtain characterizations of exponential, Pareto and power distributions in terms of sequential order statistics, Pfeifers records and progressive type II censored order statistics.
