银行资本要求须平衡诸多因素,不仅要考虑对资本成本造成影响的各因素,而且要考虑对借贷利率造成影响的各因素。标准理论预言,在完善、有效的资本市场中,降低银行杠杆率将减少其股权的风险和成本,但是整体的加权平均资本成本不变。本文... 银行资本要求须平衡诸多因素,不仅要考虑对资本成本造成影响的各因素,而且要考虑对借贷利率造成影响的各因素。标准理论预言,在完善、有效的资本市场中,降低银行杠杆率将减少其股权的风险和成本,但是整体的加权平均资本成本不变。本文据此展开实证。我们证实优化银行股权既可以降低银行系统性风险(β),同时也会导致银行特殊风险降低。然而过去40年美国的历史数据表明,经过风险调整,银行风险越低,股票回报率越高。甚至依据历史数据进行简单校准,风险加权资产的一级资本风险每增加10个百分点将会导致资本的加权平均成本每年增加60~90个基点。因为银行资产β意味着其平均风险收益只比同期国债收益高40个基点,所以在竞争激烈的借贷市场上,这个幅度的变化将以2或3倍扩展。 展开更多

Background The rise in suicides among children aged 10–14 years demands urgent attention globally.This study aims to assess the global burden of suicide-related deaths in this age group from 1990 to 2019,considering factors such as sex,geography,and sociodemographics,to inform prevention strategies and interventions.Methods The data from Global Burden of Disease 2019,encompassing 204 countries and territories,were analyzed to investigate deaths and years of life lost(YLLs)due to suicide among children aged 10–14 years.Statistical analyses,including mortality rates,YLLs,and the sociodemographic index(SDI),were conducted using standardized tools.Results In 2019,a total of 8327[95%uncertainty interval(UI)=7073–9685]children aged 10–14 years died globally due to suicide,with a mortality rate of 1.30(95%UI=1.10–1.51)per 100,000.The rates varied across countries/territories ranging between 0.05(95%UI=0.02–0.10)in South Africa and 7.49(95%UI=5.13–10.57)in Greenland.The contribution of suicide-related deaths to all-cause mortality ranged from 0.07%(95%UI=0.04%–0.15%)in South Africa to 33.02%(95%UI=24.36%–41.53%)in Greenland.Worldwide,there were approximately 636,196(95%UI=540,383–740,009)YLLs due to suicide,with a rate of 99.07(95%UI=84.15–115.23)per 100,000.The association between SDI and suicide-related deaths was evident,with higher contributions observed in countries with higher SDI.Conclusions This study reveals a concerning global burden of suicide-related deaths among children aged 10–14 years.Despite progress in reducing mortality rates,suicide remains a significant issue.While overall rates have declined,the percentage of deaths caused by suicide in this age group is increasing. 展开更多

The recent episode of global inflation is a reminder that no country lives in isolation.Like other external economic shocks,inflationary pressure too could pass through to domestic economies.In June,inflation in the United States climbed to a 40-year high,rising 9.1%over thelast 12 months,as measured by consumer price index(CPI).In the same period,theeuro zone inflation continued to set historical record at 8.6%for the entire bloc,as measuredbyharmonized CPI.Meanwhile inChina,the signals were more mixed,with CPI rising 2.5%to a 23-month high,despite producer price index(PPI)sets a 15-month low,largely due to the pandemic disruptions. 展开更多
