This paper analyzes one potential source of misspecification of existing models of the short-term interest rate and introduces a new class of discrete-time econometric specifications that nests many existing interest rate models as special cases. In existing continuous-time or time-series...

This paper compares the empirical performance of a wide variety of well-known diffusion models - with particular emphasis on the Black, Derman, and Toy (1990) term structure model - in capturing the dynamic behavior of interest rate volatility. Many popular models are nested within a more...

I introduce two-factor discrete time stochastic volatility models of the short-term interest rate to compare the relative performance of existing and alternative empirical specifications. I develop a nonlinear asymmetric framework that allows for comparisons of non-nested models featuring...

Due to the near unit-root behavior of interest rates, the movements of individual interest-rate series are inherently difficult to forecast. In this paper, we propose an innovative way of applying dynamic term structure models to forecast interest-rate movements. Instead of directly forecasting...

Stocks with large increases in call implied volatilities over the previous month tend to have high future returns while stocks with large increases in put implied volatilities over the previous month tend to have low future returns. Sorting stocks ranked into decile portfolios by past call...

Drawing upon more than 12 million observations over the period from 1996 to 2020, we find that allowing for nonlinearities significantly increases the out-of-sample performance of option and stock characteristics in predicting future option returns. Besides statistical significance, the...

This paper provides a time-series and cross-sectional investigation of the conditional and unconditional capital asset pricing model (CAPM). The unconditional CAPM fails, but the conditional CAPM with dynamic conditional correlations (DCC) succeeds in generating a significantly positive...

This paper examines the intertemporal relation between expected return and risk for 30 stocks in the Dow Jones Industrial Average. The mean-reverting dynamic conditional correlation model of Engle (2002) is used to estimate a stock's conditional covariance with the market and test whether the...

We examine the relation between expected future volatility (options' implied volatility) and the cross-section of expected returns. A trading strategy buying stocks in the highest implied volatility quintile and shorting stocks in the lowest implied volatility quintile generates insignificant...
