We generalize the concept of the natural rate of interest (Laubach and Williams, 2003; Woodford, 2003) by defining and estimating the natural yield curve (NYC) – the term structure of natural interest rates. Our motivation stems i.a. from the observation that at times when central banks attempt to directly affect long-term interest rates (e.g. via quantitative easing) the gap between the short-term real and natural rate is no more a good indicator of the monetary policy stance. We estimate the NYC on US data, document its main properties and show i.a. that in the period 2008 to 2011 the NYC allows to better capture the US monetary policy stance than the short-term natural rate. 相似文献

In this paper, we first add to what is a growing literature on the existence and nature of the environmental Kuznets curve (EKC) model for developing countries, by testing for the existence of an EKC for China using a panel data set of city-specific, annual ambient levels of SO2 pollution. We find some support for both the typical inverted-U-shaped relationship and an N-shaped, cubic configuration. More significantly, we then explore the possibility of China's “tunneling” through the EKC, by using newer, cleaner technologies, and thereby avoiding some of the environmental degradation that had often accompanied economic growth. Specifically, we estimate and economically value the health benefits realizable to Chinese cities from successful efforts to “tunnel” under the EKC over the next generation. 相似文献

Forecasting inflation with an uncertain output gap 总被引:1,自引:0,他引:1
The output gap is a crucial concept in the monetary policy framework, indicating demand pressure that generates inflation.
However, its definition and estimation raise a number of theoretical and empirical questions. This paper evaluates a series
of univariate and multivariate methods for extracting the output gap in Norway, and compares their value added in predicting
inflation. We find that models including the output gap have better predictive power than models based on alternative indicators,
and they forecast significantly better than simple benchmark models. Furthermore multivariate measures of the output gap perform
better than the univariate gaps.

Abstract The historiography of mercantilism has been described as a series of disconnected still pictures which reflect the shifting viewpoints of economic thought.1 However, historians have favoured different concepts of mercantilism not only in response to the shifts of economic science but also because they have held, explicitly or implicitly, different opinions on the problem of how economic ideas are formed and of the role they have played in historical development. The following reexamination of some of those ‘stills’ concentrate on such differences.2 相似文献

本文认为,较之资本结构,资产结构的研究更具实际应用价值和普适意义,它们才是创造公司价值和抵御各项风险的源泉。基于此,本文试图从逻辑和实证两个角度评价资产结构与企业绩效之间的关系,并希望通过评价实证结论的相关性程度,来求得各变量之间的函数方程式。在此基础上,本文再分别进行各变量的曲线拟合,试图通过在建立拟合方程模型的基础上,求出其最优资产配置值。 相似文献

本文针对传统直流电机的模型建立问题,基于曲线拟合技术,提出了简洁有效的参数辨识方法。由于实际的直流电机模型正反向参数差别很大,因此本建模方法中对直流电机的正向模型和反向模型分别对待。实验结果验证了所建立的直流电机模型的优越性能。 相似文献
