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.     

未预期货币政策与企业债券信用利差——基于固浮利差分解的研究

本文利用固息债与浮息债利差将货币政策分解成预期和未预期部分,进而探讨未预期货币政策对企业债券市场信用利差所产生的动态影响与非对称效应。实证结果表明:第一,未预期货币政策对企业债券信用利差的影响更为显著;第二,在经济周期的繁荣时期,未预期货币政策对企业债券信用利差的作用更大;第三,对比不同期限的企业债,货币政策对中长期企业债信用利差的作用更为显著,而对短期的影响较小。     

基于金融衍生工具视角的长寿风险管理

长寿风险已成为养老保障发展所面临的重要风险,而作为养老保障产品供给者的政府、年金和寿险公司等机构难以持续、有效地管理长寿风险。本文在分析长寿风险发展态势和现有管理方案的缺陷后,研究了最近的长寿风险管理工具创新及其发展动向,即死亡率巨灾债券、EIB/BNP长寿债券和远期等,并在此基础上分析了基于资本市场的长寿/死亡率风险相关衍生品设计与交易,包括长寿债券、死亡率互换、死亡率期货和死亡率期权,最后是长寿/死亡率衍生品交易市场建设的启示。     

我国资本市场可转债定价及后市走势研究

从1992年发行第一只可转换公司债券(以下简称“可转债”)至今,中国可转债市场已经历了二十多年的发展。自诞生以来,中国监管机构对可转债的发行要求不断明确,配套监管措施不断完善,可转债市场迅速发展,发行规模不断提高。然而,在2017年以前,虽然可转债的发行规模增长迅速,但其融资总额占资本市场股权产品总融资规模的比重仍处于较低水平。究其原因,一方面是因为可转债的发行主体仅限于上市公司,股权融资存在较大的不确定性;同时可转债的定价条款过于复杂,市场接受程度较低。随着2017年证监会对可转债产品的审核标准进一步明确,可转债发行规模高速增长,目前已成为资本市场上不可忽视的品种。为确定可转债定价方式,本文以“广汽转债”历年来的市场价格为数据基础,以B-S模型为分析模型,通过实证分析寻求影响可转债定价的主要因素,对未来可转债定价的研究具有一定的借鉴意义。     

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。     

Using Subordinated Debt to Monitor Bank Holding Companies: Is it Feasible?

Although accurate bond prices are difficult to come by, many have advocated that bank supervisors use subordinated debt spreads in the surveillance of large banking organizations. Our findings indicate that subordinated debt spreads are most consistent across data sources for the most liquid bonds (i.e., those of relatively large issuance size, relatively young age, issued by relatively large firms) traded in a relatively robust overall bond market. We also find a high degree of concordance in rankings of firms by their minimum spreads across bonds with especially strong agreement about which large firms are in the tails of the spread distribution at each point in time. Our time-series results further support and provide additional guidance for the use of subordinated debt spreads in supervisory monitoring, support the need for careful judgment when interpreting such spreads, highlight difficulties with currently available data sources, and motivate the need for further research.     

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.     

浅析国外储蓄国债管理经验对我国的启示

由于我国金融市场不断发展,金融产品不断丰富,储蓄国债面临极大的竞争。长期以来我国储蓄国债创新不足,发展停滞。本文分析了我国储蓄国债存在的主要问题,结合国外相对成熟的管理经验,提出相应合理化的建议。     

Empirical evaluation of the asset-allocation puzzle

We examine the portfolio-choice puzzle posed by Canner, Mankiw, and Weil [Canner, N., Mankiw, N.G., Weil, D.N., 1997. An asset allocation puzzle. The American Economic Review 87, 181–191]. From data on the portfolio composition of 470 clients of a brokerage firm, we obtain that the bonds/stocks ratio does decrease in relation to risk tolerance. This result complements the findings of CMW (1997) by focusing on actual allocations of individual portfolios rather than recommended allocations by financial advisors.
