Shock-dependent conditional skewness in international aggregate stock markets

This article uses the S_U-normal distribution to model the dynamic behavior of skewness in ten international aggregate stock indices—five indices each from developed and emerging markets. The conditional skewness process is specified as both autoregressive and dependent on lagged return shocks. Our primary result is that a negative return shock skews the time-varying distribution to the right for mature markets but to the left for emerging markets. In addition, we find that the asymmetry in volatility is noticeably larger in developed markets than in emerging markets. Finally, including the skewness process in modeling has no effect on the asymmetry and persistence in volatility obtained. These results are different from those of previous studies, which demonstrate the existence of both effects.     

Sovereign Credit Risk,Banks' Government Support,and Bank Stock Returns around the World

We explore the joint effect of expected government support to banks and changes in sovereign credit ratings on bank stock returns using data for banks in 37 countries between 1995 and 2011. We find that sovereign credit rating downgrades have a large negative effect on bank stock returns for those banks that are expected to receive stronger support from their governments. This result is stronger for banks in advanced economies where governments are better positioned to provide that support. Our results suggest that stock market investors perceive sovereigns and domestic banks as markedly interconnected, partly through government guarantees.     

场外交易市场法律监管制度设计的博弈分析

利用博弈论分析方法,对影响场外交易市场建设的监管制度、交易制度、信息披露、市场准入等进行分析,认为我国场外交易市场法律监管制度设计应从提高场外交易市场的法律地位着手,合理界定市场主体准入与退出标准,制定与场外交易市场特点相适应的信息披露制度,审慎引入做市商制度,建立顺畅的转板机制,采用灵活性、动态化的监管方式。

论多元文化主义的实践性特征

多元文化主义是为解决因文化多样性和弱势群体而引发的社会问题而首先由加拿大政府在一份政策性报告里提出来的。无论它的理论背景、理论界定、还是它的理论实施都显示出了多元文化主义的实践性特征。多元文化主义与其说具有理论的特征,不如说它更具有实践的特征。本文将试图对多元文化主义的这一特征进行论述。     

Houses as ATMs: Mortgage Refinancing and Macroeconomic Uncertainty

Mortgage refinancing activity associated with extraction of home equity contains a strongly countercyclical component consistent with household demand for liquidity. We estimate a structural model of liquidity management featuring countercyclical idiosyncratic labor income uncertainty, long- and short-term mortgages, and realistic borrowing constraints. We empirically evaluate its predictions for households' choices of leverage, liquid assets, and mortgage refinancing using microlevel data. Taking the observed historical paths of house prices, aggregate income, and interest rates as given, the model accounts for many salient features in the evolution of balance sheets and consumption in the cross-section of households over 2001 to 2012.     

信贷配给及信息甄别博弈理论的文献分析及评述

自从Stiglitz＆Weiss和Jaffee＆Russell这两篇经典文献从信息不对称角度解释信贷配给现象之后,涌现出众多的理论文献对信贷市场的信贷配给现象和信息甄别问题进行了研究。现有的信贷市场基本理论研究在以下几方面取得成果：一是信贷配给的信息不对称成因;二是抵押物可以成为银行的风险分类工具：三是贷款额度可以成为银行的风险分类工具。同时其理论研究框架在银行类型假定、借款人类型假定、以及描述借款人行为的效用函数等方面存在局限性,有待进一步深入研究。     

社保基金持股与企业盈余质量:A股上市公司的证据

本文利用中国A股上市公司2006-2015年的数据,研究社保基金持股对上市公司盈余质量的影响。我们用上市公司财务重述作为测度盈余质量的指标,发现社保基金持股能够显著降低企业发布财务重述的概率,这表明社保基金对上市公司盈余质量的提高具有促进作用。并且,社保基金的这一治理作用在国有企业、内部治理水平较差以及市场化程度较低地区的上市公司中更加显著。通过双重差分模型和安慰剂检验等方法弱化了内生性问题之后,以上结论依然成立,说明社保基金持股和盈余质量提升之间存在因果关系,我们称之为社保基金的公司治理作用。进一步研究发现,社保基金可以通过抑制控股股东资金占用、增加机构调研次数等途径提升被持股公司的盈余质量。本文有助于认识和评估社保基金持股对于上市公司的监督与治理作用。     

Accruals and the Conditional Equity Premium

Accruals correlate closely with the determinants of the conditional equity premium at both the firm and the aggregate levels. The common component of firm‐level accruals, which cannot be diversified away by aggregation, explains the positive relation between aggregate accruals and future stock market returns. The residual component, which accounts for most variation in firm‐level accruals, is responsible for the negative cross‐sectional relation between firm‐level accruals and future stock returns. Consistent with the risk‐based explanation, aggregate accruals, as a proxy for the conditional equity premium, forecast changes in aggregate economic activity. Moreover, we document a similar comovement of earnings with the conditional equity premium at both the firm and the aggregate levels, which helps explain the negative relation between changes in aggregate earnings and contemporaneous market returns.     

开放条件下知识产权保护和社会福利效应

开放条件下知识产权保护和社会福利效应的规范研究显示,发达国家从创新主体利益角度,要求发展中国家加强知识产权保护,但这并不能保证发达国家及世界福利水平的提高;技术创新和技术扩散是知识产权保护影响福利水平的两个最重要传导机制,其对南方国家知识产权保护的反应也存在不确定性。一些实证研究显示,知识产权保护对经济增长、国际贸易、FDI和技术转让均有影响。从减少贫困和失业以及产业结构变迁等发展经济学视角展开研究,是对现有文献的一个重要拓展方向。
