The effectiveness of government spending on education and health care in developing and transition economies 总被引:2,自引:0,他引:2
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. 相似文献

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.

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。 相似文献

Using detailed data for fieldwork hours and audit hours by rank from audit engagements in Korea, we examine whether audits conducted under workload imbalance, proxied by busy‐season audits, impair audit quality, and how auditors adjust staff assignments for busy‐season audits. We generally find that busy‐season audits are associated with lower audit quality, and that audit firms reduce the involvement of senior auditors during busy‐season audits. In addition, the greater the involvement of senior auditors and junior auditors, the lesser the deterioration in audit quality. Finally, although there is no increase in interim audits in response to workload imbalance during busy seasons, increasing interim audits can mitigate the negative impact of busy‐season audits on audit quality. Our results are relevant to auditors and regulators, who have expressed concerns about the adverse effects of workload imbalance on audit quality. 相似文献

This paper proposes a new strategic planning model for high-speed rail ventures. It is a mixed-integer optimization model that applies to a given line and focuses on two key strategic decisions: station location and fleet composition. Our purpose is to improve on previous station location models by including fleet composition decisions. In the new model, we additionally take into account in an approximate fashion the interrelationships between strategic and subsequent tactical decisions, regarding line planning, train scheduling and fleet assignment issues. The usefulness of the model is demonstrated for a case study involving a planned Lisbon-Oporto high-speed rail line. 相似文献

A review of research on personality in teams: Accounting for pathways spanning levels of theory and analysis 总被引:1,自引:0,他引:1

Over the last half century there has been a great deal of interest in the role of personality in teams. In this article we review the theoretical and empirical research on this topic to summarize what we have learned and also to provide a foundation for future research necessary for application of this knowledge to human resource management decisions. We describe research that emphasizes both team- and individual-levels of analysis and theory, and we discuss recent efforts that attempt to bridge these two levels. We conclude by identifying several issues that should take precedence in research in order to advance our understanding of the role of personality in teams. 相似文献
