Abstract. This study examines whether mandatorily redeemable preferred stock (MRPS) is priced more like debt or equity by (1) investigating its debt and equity characteristics and (2) specifying conditions under which one characteristic would dominate the other. Based on a sample of 113 nonconvertible MRPS issued during 1970 to 1990, our results are consistent with the view that MRPS has both debt and equity characteristics. The debt (equity) feature is more pronounced among nonutility (utility) issues. Within the utility group, we find high (low) rated MRPS issues to be more debt (equity) like. Our results appear to support current MRPS disclosure rules.  相似文献

地方政府债务权责划分是一国分级财政体制的重要内容。实现中国地方政府债务的合法化已经成为解决当前地方政府债务问题的前提条件。地方政府债务的合法化不仅是债务融资权的界定问题,更是管理责任的归属问题。近年来中国某些地方已经开始自发地探索地方层面上的政府债务权责划分的方法。国家应尽快制定统一的法规,赋予地方政府合法举债权,但应严格控制债务规模、界定使用范围。应在财政部和省市县财政部门设立债务管理机构,明确地方政府的债务偿还及风险管理责任,加大债务监督力度。  相似文献

税务行政处罚的法理探析   总被引:1,自引:0,他引:1  
法学意义上的税收是一种金钱给付关系。关于税收的法律关系性质有权利关系说和债务关系说两种观点,不同观点之下对于税务行政处罚的法理有不同的分析。事实上,国家和纳税人之间是一种公法意义上的债权债务关系,税务行政处罚是国家对纳税人不按时履行税收合约的一种惩罚。  相似文献

We examine the determinants of the new issue maturity of corporate bonds. As credit rating decreases, new bond issues have longer maturities, but substantial variation in maturity within each rating class remains. We seek to explain the variation of new issue maturity within credit classes. We find that asset maturity, security covenants, and macroeconomic conditions influence the new issue maturity of bonds within rating categories.  相似文献

We provide evidence for the euro area of spillovers from foreign public debt auctions into domestic secondary‐market auction cycles. We also confirm existing evidence of such spillovers from domestic issues into the domestic secondary market. Consistent with a theory of primary dealers’ limited risk‐bearing capacity, we find that auction cycles from domestic issues are stronger during the recent crisis period, whereas cross‐border effects are stronger in the precrisis period, but this evidence is not strong. This finding likely reflects the opposing effects of reduced sovereign bond market integration during the crisis and higher yield covariances caused by more market volatility.  相似文献

Deaths, injuries and disabilities resulting from road traffic injuries (RTIs) are a public health major concern. This study aims to calculate the burden of RTIs in Kermanshah Province in Iran. In this study to determine the years of life lost (YLL) related to RTIs, the National Death Registration and Forensics Medicine census data were employed. We use forensic medicine data to calculate the incidence of non-fatal injuries and years lost due to disability (YLD). The cause of death and non-fatal injuries was classified using ICD-10 codes and 23 groupes of global burden of diseases (GBD) 2010. The disability-adjusted life year (DALY) estimated on the guidelines of the GBD 2010 and age and sex structure was taken from the National Statistic Center for the year 2010. Overall, 70.8% of the subjects were males. The fatal and non-fatal injury rates of RTI were 51.3 and 283.6 per 100,000 persons, respectively. YLLs and YLDs were 46613 (24.5 per 1000) and 3405 (1.8 per 1000) in both sexes, respectively. The disability adjusted life years were 40711 in males, 9306 in females and 50018 in both sexes (42.5, 9.8 and 26.3 per 1000, respectively). More than 93% of DALY was from YLL (24.5 per 1000), with a small proportion for YLD (1.8 per 1000). Accounting for more than 50,000 DALY attributed to RTIs, traffic injuries is a major public health and socioeconomic problem in Kermanshah. Designing cost-effective interventions based on comprehensive and multi-sectoral programmes at the national and provincial levels can save many lives and resources that are lost every year. Undoubtedly, establishing a surveillance system at the sub-national level and measuring the burden of injuries, as in this study, can help policy-makers and planners in lessening the burden of RTIs.  相似文献

In the wake of the recent financial and debt crises, the conduct of macroeconomic policies in the emerging MENA economies has recently become critical in determining those countries future economic situation, due to the accumulation since the early 1990s of a sizable level of external debt, and the pursuit by some countries of a fixed exchange rate regime. Using time series econometric models, this study assesses the sustainability of macroeconomic policies in a selected sample of 4 MENA countries. The empirical results point to sustainable fiscal and exchange rate policies in Tunisia and Morocco, and unsustainable external debt and exchange rate policies in Egypt and Jordan. While Egypt has recently moved to a flexible exchange rate regime, if Jordan still opts for maintaining a fixed exchange rate arrangement, it will have to implement crisis-prevention measures, namely by exercising fiscal discipline, and managing properly its external debt and foreign reserves.  相似文献
