Assessments of the trade-off theory have typically compared the present value of tax benefits to the present value of bankruptcy costs. We verify that this comparison overwhelmingly favors tax benefits, suggesting that firms are under-leveraged. However, when we allow firms to experience even...

This paper presents a new model for the valuation of European options, in which the volatility of returns consists of two components. One is a long-run component and can be modeled as fully persistent. The other is short-run and has a zero mean. Our model can be viewed as an affine version of...

We build a new class of discrete-time models that are relatively easy to estimate using returns and/or options. The distribution of returns is driven by two factors: dynamic volatility and dynamic jump intensity. Each factor has its own risk premium. The models significantly outperform standard...

The cross section of stock returns has substantial exposure to risk captured by higher moments of market returns. We estimate these moments from daily Standard & Poor's 500 index option data. The resulting time series of factors are genuinely conditional and forward-looking. Stocks with high...

We study the ability of three-factor affine term-structure models to extract conditional volatility using interest rate swap yields for 1991-2005 and Treasury yields for 1970-2003. For the Treasury sample, the correlation between model-implied and EGARCH volatility is between 60% and 75%. For...
