房价问题已经成为社会关注的焦点,建立科学的房价合理性评价指标体系成为当前亟待解决的重要问题。许多研究者认为房价收入比是比较合理的方法,本文认为用房价收入比衡量房价合理性不符合当前中国的实际,存在三个方面的缺陷。科学的评价体系必须能够反映收入结构、支出结构和住房供应结构的差异,以机会均等作为房价合理的判别准则。按照这一设想,本文提出了以“住房负担能力、住房机会指数和住房机会均等指数”为核心的房价合理性评价指标体系,并对2005年江苏某市房价合理性进行了实证分析,提出了改善其房价合理性的相关建议。 相似文献

Singapore’s remarkable success in economic development has been strongly associated with the country’s vigorous efforts to embrace the Information and Communication Technology (ICT) revolution to promote economic growth. This study provides a comprehensive investigation of the contributions of ICT to Singapore’s economic growth during the 1990–2008 period. It documents three key findings. First, there is a strong positive association between the intensity of ICT use and value-added and labor productivity growth at the sector level. Second, ICT investment contributed approximately 1 percentage point to Singapore’s GDP during 1990–2008, and its role in driving economic growth has become increasingly important over time. Third, the contribution of the ICT manufacturing sector to Singapore’s growth was notable, but it was on the decline and faced difficult restructuring challenges. This paper also provides valuable policy lessons and strategic insights for governments in both developed and developing countries that aspire to embrace ICT to promote economic growth. 相似文献

Women make an increasingly important contribution to the skilled workforce. Nations like Australia that suffer skill shortages need not only to attract but also retain more skilled female migrants. The latter has become an important policy issue in Australia because of modest retention rates. While much of the relevant literature focuses upon migrant attraction, we address the retention decision. We derive and empirically test a framework incorporating the key explanatory factors in the decision of skilled female migrants whether to remain in Australia. Our results have important implications for current policy directions. 相似文献

The objectives of this article are to illustrate theoretically and empirically how to incorporate an ad valorem tariff in spatial equilibrium models and show the equivalence of three approaches (primal, dual and MCP) of spatial equilibrium trade modelling. The article lays out in detail the theory, empirical applications and the results for all three approaches so that trade modellers can easily follow and apply them in their work. The primal approach is commonly used by spatial equilibrium modellers, though the dual approach corresponds to the textbook depiction of consumer surplus, producer surplus and gains from trade. The Mixed Complementarity Problem (MCP) is not commonly used by spatial equilibrium modellers, though it is relatively simpler if the modeller knows the equilibrium conditions. This article also presents advantages and disadvantages of each approach. 相似文献

文章提出了研究假设,设计了调查问卷,运用多种统计方法对问卷进行分析,对研究假设进行了分析验证。研究结果发现了7个奢侈品感知价值因子,分别命名为"品质价值"、"价格价值"、"社交价值"、"独特价值"、"炫耀价值"、"自我赠礼"、"价值保持"。探讨了感知价值因子与人口统计变量之间的关系。基于奢侈品感知价值的7个因子对样本进行聚类分析,结果发现样本可以划分为5个不同的消费者群体,不同群体之间存在显著差异。 相似文献

资本配置是银行风险管理的核心,是决定银行竞争力的重要因素.经典的资本配置理论均以信息在银行内部各机构完全对称作为基本假设,忽略了总分行问的委托代理关系.鉴于此,本文借鉴PCA模型,在商业银行内部构建一套资本配置的优化机制,以提高银行资本配置的有效性. 相似文献

This article studies the performance of the high-order moment capital asset pricing model (CAPM) market models in emerging markets. We apply the cubic market model (4-moment CAPM) to 16 emerging market stock indices ranging from January 2010 to September 2015. Performance of the model is evaluated through the Fama and MacBeth’s two-step regression and through different corrections proposed in the literature, as well as generalized method of moments (GMM) estimation. According to Fama–MacBeth’s procedure, CAPM, the quadratic and cubic market models seem to be insignificant for the analyzed sample; however, the GMM estimation shows that quadratic model is valid for Indian, Polish, and Thai country indices, whereas cubic market model is accurate for Indian country index. 相似文献
