长寿债券的运行机制与定价模型

通过分析长寿债券的市场发展以及连续型和触发型两类长寿债券的运行机制,采用风险中性定价方法推导出当死亡率服从双指数跳跃(DEJD)分布时,长寿债券的定价解析式,研究发现,无论从理论还是实践看,设计并发行触发型长寿债券是一种应对长寿风险更为明智的选择。     

“银边债券”：关于城市公债的理性思考与现实选择

长期以来，我国一直禁止地方政府发行公债，而国外地方政府发债融资弥补城市基础建设资金不足，是一种极为普遍的现象。本文对从我国建立城市公债制度的必要性和可能性的分析出发，提出了建立我国城市公债制度的基本思路。     

“一带一路”倡议与公司债信用利差

本文以中国“一带一路”倡议的出台作为准自然实验,采用双重差分法考察国家倡议对微观企业债券信用利差的影响。研究发现:(1)相对于非支持企业,“一带一路”倡议实施能够显著降低支持企业的公司债二级市场信用利差,该结论在一系列稳健性检验之后仍然成立。(2)通过考察“一带一路”倡议的债券市场反应,我们发现相比于非支持企业,支持企业在倡议提出后有显著更高的债券累计超额回报率。(3)进一步检验后发现,“一带一路”倡议对公司债二级市场信用利差的降低作用主要通过资源效应和信息效应来实现。并且,政策影响范围主要集中在重点对接行业以及重点对接省份的企业。(4)“一带一路”倡议还对公司债一级市场的发行表现产生影响。具体表现为:在倡议实施之后,受倡议支持企业发行的公司债,其一级市场发行利差下降幅度更大,且包含的担保条款以及限制性契约条款显著更少。本研究探讨了“一带一路”倡议对公司债券市场的政策效应,对未来推进“一带一路”建设,提高资金融通效率具有参考意义。     

中国上市公司可转换债券融资分析——基于与增发的比较研究

本文通过对我国2001年至2006年公告拟发行可转债及拟增发的上市公司财务指标进行比较分析,试图探求上市公司发行可转债的动因。采用单因素和Logistic多元回归分析的结果表明,资产负债率、市净率与可转债融资选择显著负相关,公司规模、成长性、经营现金流易变程度与可转债融资选择显著正相关,成立年限、实物资产比例及盈利性对上市公司再融资选择无显著影响。     

Learning about Risk: Some Lessons from Insurance

This paper argues that in the fundamental subject of financialrisk analysis, some valuable lessons may be drawn from insurance.The probability of ruin, defined as a first passage time, carriesa dynamic element whose absence in Value at Risk is one liability,among others. Extreme value theory, which has been successfullyapplied to insurance shortly after it was introduced in probability,may offer a coherent framework for analyzing the extreme movessuch as the ones observed in recent foreign exchange and financialcrises. Lastly, we show that the genuine hazards generated byglobal capital markets and illustrated by the events of summer1998, generate a market incompleteness that existing modelsof defaultable bonds do not fully address. In contrast, thelong experience of risk premium analysis in the insurance andreinsurance industry, as well as the existence of historicaldata on natural disasters, render the valuation of catastrophebonds less perilous than that of defaultable bonds.     

城投债的担保可信吗？——来自债券评级和发行定价的证据

本文以中国地方融资平台公司发行的城投债作为研究样本,考察债券市场的评级机构和机构投资者对城投债“双重担保”(债券的“名义担保”与地方政府的 “隐性担保”)所做反应的异质性。研究发现:有担保的债券和地方政府公共财政收入的增加均有利于提高债券评级,但对债券信用利差的降低却无显著影响。这种现象的产生,其原因可能在于债券评级市场“发行人付费”的商业模式下,评级机构与发行人之间的合谋导致了债券的发行评级并不能完全真实地反映债券违约风险,从而机构投资者只能依赖其内部评级体系对此进行纠正。这种现象的存在让中国债券市场上的评级机构普遍面临信任危机,同时也对债券市场的进一步发展形成阻碍。     

论基本养老保险基金投资国债的流程重塑

本文分析了当前基本养老保险基金投资国债面临的问题。本文认为,根据我国国债市场现状和我国基本养老基金的运行特点,应取消地方社保部门的养老基金管理权,归并养老基金投资账户,由中央政府养老基金管理机构统一招标确定基金托管银行和投资机构,地方社保部门再根据资金需求申购或赎回养老基金。     

Disaggregation and the equity premium puzzle

Standard macroeconomic models cannot explain why stocks so greatly outperform bonds. However, this result depends on the use of aggregate consumption data. If markets are incomplete, then a representative agent might not exist and it is necessary to use consumption data at the household rather than aggregate level. In the household data, I fail to reject the Euler equation when the coefficient of relative risk aversion is as low as 2.7–3.8. This result is robust in a very general framework and I prove that many of the tests used in the literature are biased.     

美国金融危机成因分析及对我国的警示

美国金融危机引发全球金融市场动荡。这场金融危机从美国的房地产市场开始,以惊人的速度蔓延,波及信贷市场、资本市场,对全球尤其是西方金融机构和金融市场造成重大冲击,短期内升级为全球金融风暴。我国目前正处于资产价格上涨、信贷投放过度的经济环境之中,美国的金融危机给我国敲响了警钟。本文通过描述此次危机的发展脉络,在分析美国金融危机背景的基础之上,从强化房地产按揭贷款业务风险管理、审慎推进资产证券化等六个方面得出了对我国的警示。     

Funding advantage and market discipline in the Canadian banking sector

We employ a comprehensive data set and a variety of methods to provide evidence on the magnitude of large banks’ funding advantage in Canada in addition to the extent to which market discipline exists across different securities issued by the Canadian banks. The banking sector in Canada provides a unique setting in which to examine market discipline along with the prospects of proposed reforms because Canada has no history of government bailouts, and an implicit government guarantee has been in effect consistently since the 1920s. We find that large banks have a funding advantage over small banks after controlling for bank-specific and market risk factors. Large banks on average pay 80 basis points and 70 basis points less, respectively, on their deposits and subordinated debt. Working with hand-collected market data on debt issues by large banks, we also find that market discipline exists for subordinated debt and not for senior debt.
