Dimensions of quality upgrading

The impact of the Central and Eastern European (CEE) economies’ trade integration with European markets on CEE trade structures has been studied extensively. These studies frequently observe a quality upgrading of CEE exports. In this paper we consider three dimensions of quality upgrading: upgrading across industries, upgrading across different quality segments within industries and, finally, product upgrading within quality segments inside industries. For the analysis we partition industries into quality segments based on EU‐15 import unit values. The results for ten CEE countries (comprising the CEE‐5, the Baltics and South East Europe) and thirteen industries suggest fundamental differences, both across country groups and across the three different notions of quality upgrading. The CEE‐5 show no evidence of entering a ‘low‐quality trap’ in all three dimensions. By contrast, while there is a general catching‐up process across industries and inside quality segments, the second notion of low‐quality specialization may be applicable within the high‐tech industries to the performance for the Baltics and South East Europe as a group.

Human capital composition, growth and development: an R&D growth model versus data

The effect of human capital composition on growth and development has been somewhat neglected in economic literature. However, evidence has suggested the importance of engineering and technical (high-tech) skills to economic growth, and international organizations have suggested their shortage in developed countries. Using a standard increasing variety growth model, we propose various measures of human capital composition that are related with economic growth and development. When compared to data, the model does well in explaining the rate of growth and the level of development as a function of these measures. “the British colonies had a better educated population (...). Education was secular with emphasis on pragmatic skills and yankee ingenuity (...). The 13 British colonies had nine universities in 1776 for 2.5 million people. New Spain, with 5 million, had only two universities (...) which concentrated on theology and law.” –(Maddison, 2001)     

The effectiveness of government spending on education and health care in developing and transition economies

Recent studies show that corruption is associated with higher military spending [Eur. J. Polit. Econ. 17 (2001) 794] and lower government spending on education and health care [J. Publ. Econ. 69 (1998) 263]. This suggests that policies aimed at reducing corruption may lead to changes in the composition of government outlays toward more productive spending. However, little empirical evidence has been presented to support the claim that public spending improves education and health indicators in developing and transition countries. This paper uses cross-sectional data for 50 such countries to show that increased public expenditure on education and health care is associated with improvements in both access to and attainment in schools, and reduces mortality rates for infants and children. The education regressions are robust to different specifications, but the relationship between health care spending and mortality rates is weaker.     

The lexicographic composition of abstract games

The lexicographic composition of reflexive and complete binary relations (which are often called abstract games) is studied. The necessary and sufficient conditions are obtained for a lexicographic composition of quasi transitive relations to be quasi transitive.The case of acyclicity of lexicographic composition of two relations is also investigated.

生育政策的地区差异与儿童营养过剩关系研究

近年来,中国的肥胖儿童不断增多。由于该现象发生在“独生子女”政策开始实施以后,后者被认为是前者之因。然而,实证研究的缺乏使生育政策与儿童营养过剩之间的关系尚不明确。使用“中国健康和营养调查”数据,探讨政策与儿童(0-12岁)营养过剩之间的关系。多层模型和纵向分析结果显示,其一,儿童营养过剩的比例在90年代持续攀升,但增长速度较慢。其二,虽然生活在一孩生育政策地区的儿童营养过剩的比例高于其它地区儿童,独生子女营养过剩的比例超过非独生子女,但在其它条件同等的情况下,生育政策的地区差异和姊妹结构与儿童营养过剩概率无显著关联。分析结果并不支持“独生子女政策造成了儿童肥胖”的公共观点。影响儿童营养过剩的主要因素包括父母的体重、母亲的教育、社区发展水平和省份。     

从博弈的角度看中小股东解决纠纷的过程--从一个流行模型的残缺谈起

经研究发现 ,张维迎教授在 2 0 0 1年第五版的《博弈论与信息经济学》中所借用的承诺要胁诉讼博弈例子中对诉讼费用的处理有点不妥 ,便作出了适当的调整 ,但却得出了令人沮丧的结论 :承诺要胁诉讼不成立 !继续研究发现只有打破这种败诉风险由当事人承担的机制 ,才能传递出有力量的信号 ,才能做到真正的威胁 ,那就是建立“生死与共”的竞争性的律师定价机制和保费率真正是胜诉率信号的诉讼费用保险机制与最经济的诉讼程序与非诉讼程序、保障其实现的机制和可供的备选机制。本文论证了其合理性

国有商业银行费用偏好与组织绩效的实证分析

单一国有产权结构、出资人监督缺位和委托代理问题共同决定了国有商业银行费用扩张偏好.实证结果表明,费用规模扩张侵蚀了出资人利润性收益空间,成为国有商业银行利润率指标偏低的解释因素.因此,国有商业银行制度变迁必然包含能够抑制费用偏好的制度工具创新.政府宏观经济目标的退出可以使出资人硬化利润约束,但在政府效用函数不可能全面退出国有商业银行的现实背景中,通过引进在位寡头之间的竞争可以为国有商业银行利润目标约束硬化提供外在制衡条件;同时,产权多元化改革基础上的银行治理结构完善则是解决委托-代理问题下经营者费用偏好问题的彻底措施.
