中国郑州棉花期货市场的国际定价功能研究

本文借助计量经济学的分析方法,对郑州商品交易所、纽约期货交易所期棉价格与国内棉花现货价格这三者的关系进行了研究,并测算了郑州商品交易所与纽约期货交易所在价格发现中的贡献份额。研究结果表明,三者之间存在协整关系,纽约期货市场在国际棉花定价体系中占有主导地位,而导致郑州棉花期货市场国际定价功能弱化的原因则是国内棉花期货市场与现货市场缺乏有机联系。     

Replacement Investment: Optimal Economic Life Under Uncertainty

Replacement investment is essentially a regenerative optimal stopping problem; that is, the key decision concerns when to terminate the life of existing plant – and hence when to start over again. This paper examines this optimisation problem within a continuous time framework and studies the qualitative and quantitative impact of uncertainty on the timing of new investment (and the criteria that should be used for terminating the life of existing plant).

How Issue Size, Risk, and Complexity are Influencing External Financing Costs: German IPOs Analyzed from an Economies of Scale Perspective

This paper is focused on the cost of raising capital in Germany. A cross-sectional analysis of flotation cost data for 117 IPOs over the years 1993–1998 is presented. We find average flotation costs to be 7.77 percent of gross proceeds, while underwriting fees average 5.01 percent. Our results extend the literature in two important directions. First, contrary to the conventional economies of scale view we find marginal spreads to be rather constant in gross proceeds and to be higher for more risky and more complex offerings. Fixed costs amount to 5 to 9 percent of underwriting fees. Second, by applying a principal component analysis we find issue size, an issuer risk factor, and an offering method complexity factor to have an economicaly meaningful impact on underwriting fees.     

New Labour and Community Protests: the Case of the Govanhill Swimming Pool Campaign, Glasgow

Taking the case study of a community based protest against the closure of a swimming pool in Glasgow, this paper seeks to raise important critical questions about some of the key ideas informing New Labour's urban policy agenda: social capital and active community. It argues that normative notions of active citizenship seriously conflict with bottom-up community protests, highlighting in the process issues of power and inequality. Against claims that New Labour is promoting government through community, here we claim that in the context of this community protest, there was government against community.     

全面理解人力资本的经济价值——教育经济学与培训经济学的融合

教育经济学不应只是正规学校教育的经济学,在终身学习的理念下,正规学校教育的结束并不意味着学习步伐的停滞和人力资本投资的终结。教育经济学未来拓展的路径,除了理论基础上的"外延式"发展外,还可以在原有的人力资本理论框架内走一条"内涵式"发展的道路,即强调综合考察人力资本投资的多种途径,特别是教育和培训这两种最主要的人力资本投资形式,让教育经济学走出正规学校教育经济学的固有领地,团结在人力资本理论的名义下,与培训经济学融合,走向人力资源开发研究的广阔天地,惟其如此,才能全面、深入地研究人力资本的经济价值及其实现机制。     

FACTORS THAT AFFECT THE LONG‐TERM SURVIVAL OF MICRO,SMALL AND MEDIUM ENTERPRISES IN ETHIOPIA

There is an increasing recognition of the potential importance of micro, small and medium enterprises (MSMEs) for employment, income and poverty reduction in Ethiopia. Although the MSME sector contributes significantly to the national economy, the high failure rate among well established small businesses and enterprises is a matter of major concern. A random sample of 500 small businesses and enterprises selected from five major cities in Ethiopia were followed up for 6 years in order to assess the impact of influential factors that affect the long‐term survival and viability of small enterprises. Hazard ratios estimated from the Cox Proportional Hazards Model were used to quantify the impact of key predictors of survival. Businesses that ceased operation were characterised by inadequate finance (61%), low level of education (55%), poor managerial skills (54%), shortage of technical skills (49%), and inability to convert part of their profit to investment (46%). The study shows that participation in social capital and networking (iqqub schemes) was critically helpful for long‐term survival. Businesses that did not participate in iqqub schemes regularly were found to be 3.25 times more likely to fail in comparison with businesses that did. Results of the study have implications that could be used for developing policy initiatives that are aimed at fostering long‐term growth in small businesses and enterprises.     

超市进货交易关系法律调整的若干问题探讨——论“零供”关系法律调整

近年来，我国零售商供应商矛盾突出，引起了各方关注。商务部等五部委发布的《零售商供应商公平交易管理办法》，是近年来专门调整零供关系的政府部门规章，在稳定流通秩序方面发挥了一定的作用，但对此也有一些不同观点。为完善零供（买卖）关系的法律规范体系，推进和谐商业环境及商事法治建设，本文对调整零供关系的法律属性，少数零售企业恶意占压、骗取供应商贷款的综合治理，风险预誓机制等相关问题提出了自己的一些见解。     

基于我国彩电企业多元化战略的实证研究

文章从实证的角度，对我国彩电企业多元化发展战略与公司绩效之间的相关性进行研究，结果显示，企业总体多元化程度与资产回报率、销售利润率和净资产回报率的相关系数为负值，即多元化程度越高的彩电企业，其公司绩效越差。针对目前我国彩电企业盲目实施多元化战略的误区，文章提出了相关对策及建议。
