This study proposes a hybrid information approach to predict corporate credit risk. In contrast to the previous literature that debates which credit risk model is the best, we pool information from a diverse set of structural and reduced‐form models to produce a model combination based on credit risk prediction. Compared with each single model, the pooled strategies yield consistently lower average risk prediction errors over time. We also find that while the reduced‐form models contribute more in the pooled strategies for speculative‐grade names and longer maturities, the structural models have higher weights for shorter maturities and investment grade names.  相似文献

A multidimensional analysis of poverty in China from 1991 to 2006   总被引:1,自引:0,他引:1  
Most studies have reported non negligible improvements for China in terms of poverty during the last three decades. However, this result is potentially hampered by two limitations. First, it may be contingent to the specific choices made regarding the poverty line and the poverty indices used for the analysis. As a consequence, it may collapse if one uses alternative poverty lines or poverty measures. Second, it results from a focus on the sole monetary aspects of poverty. As income does not cover all facets of well-being and since the relationship between these two concepts are quite fuzzy, it may be worth using a broader view of well-being, hence opting for a multidimensional approach of poverty analysis. In the present paper, these two issues are addressed using multidimensional stochastic dominance procedures on the joint distribution of income, education and health in seven Chinese provinces.  相似文献

This article measures technological progress in oceanic shipping directly by using a large database of daily log entries from British, Dutch, and Spanish ships to estimate daily sailing speed in different wind conditions from 1750 to 1850. Against the consensus among economic (but not maritime) historians that the technology of sailing ships was fairly static during this time, we find that average sailing speeds of British East India Company and Navy ships in moderate to strong winds rose considerably after the 1770s. Driving this progress was the introduction of coppering in the 1780s, but subsequent rises are probably due to a continuous evolution of sails and rigging, and improved hulls that allowed a greater area of sail to be set safely in a given wind. By contrast, the speeds of Dutch and Spanish vessels were stagnant. Using separate data on the crossing times of Atlantic mail packets, we find gradual progress from the 1750s, followed by marked improvements when American packets appeared in the 1820s.  相似文献

This paper explores the opposition to housing stock transfer in Glasgow in the early 1990s. Taking the position of anti-transfer campaigners, it argues that transfer can be interpreted as a form of 'privatisation' involving a profound restructuring in the role of the state in a key heartland area of welfare provision. Using interviews from housing campaigners in Glasgow, the paper argues that the much-heralded rhetoric about housing stock transfer as promoting tenant choice is highly contentious and misleading. The paper includes by highlighting that dispite the move to transfer in Glasgow, there remains a significant campaign against transfer in other parts of the UK.  相似文献
