  • 详情 再融资政策、上市公司增长冲动与业绩分布
    中国上市公司存在着强烈的增长冲动。公司可以利用盈利水平来发送自身质量的信号,以获得更多的再融资支持未来的增长,但这要以牺牲现期增长水平为代价。当证监会决定未达到强制性业绩标准的公司不允许再融资时,一些低质量公司为获得再融资不得不牺牲现期的增长水平以追求达到再融资标准的盈利水平,这是“10%”、“6%”现象产生的原因。如果考虑到公司可能操纵业绩,公司将比较作假成本、牺牲增长水平的成本和获得再融资的收益以决定是否和怎样达到再融资标准,“10%”、“6%”现象依然存在;此时,一些质量很低和很高的公司将会达到再融资标准,而质量处于中间层的公司将不会达到再融资标准。

  • 详情 Modeling the Dynamics of Credit Spreads with Stochastic Volatility
    This paper investigates a two-factor affine model for the credit spreads on corporate bonds. The Þrst factor can be interpreted as the level of the spread, and the second factor is the volatility of the spread. The riskless interest rate is modeled using a standard two-factor affine model, thus leading to a four-factor model for corporate yields. This approach allows us to model the volatility of corporate credit spreads as stochastic, and also allows us to capture higher moments of credit spreads. We use an extended Kalman Þlter approach to estimate our model on corporate bond prices for 108 Þrms. The model is found to be successful at Þtting actual corporate bond credit spreads, resulting in a signiÞcantly lower root mean square error (RMSE) than a standard alternative model in both in-sample and out-of-sample analyses. In addition,key properties of actual credit spreads are better captured by the model.

  • 详情 比较制度分析框架下的银监会体制效率:约束与松弛――兼论比较制度分析的方法论修正
    运用严格的比较制度分析方法,在非正式制度贡献份额较重的中国公共事务协调文化中,评价中国金融监管体制转换效率,我们发现,银监分立将带来巨大的制度转换成本和协调成本。在现行中国银监会监管格局下,提高中国金融监管效率的优选策略是,通过提高监管独立性和权威性,通过松弛外部约束条件,以及通过赋予央行“紧急磋商”权力等措施,实现制度运行成本最小化。

  • 详情 Decomposing the Default Risk and Liquidity
    This paper develops a reduced form model of interest rate swap spreads. The model accommodates both the default risk inherent in swap contracts and the liquidity difference between the swap and Treasury markets. We use an extended Kalman Þlter approach to estimate the model parameters. The model Þts the swap rates well. We then solve for the implied general collateral repo rates and use them to decompose the swap spreads into their default risk and liquidity components. This exercise shows that the default risk and liquidity components of swap spreads behave very differently: although default risk accounts for the largest share of the levels of swap spreads, the liquidity component is much more volatile. In addition, while the default risk component has been historically positive, the liquidity component was negative for much of the 1990s and has become positive since the Þnancial market turmoils in 1998.
