Many economic and financial time series have been found to exhibit dynamics in variance; that is, the second moment of the time series innovations varies over time. Many possible model specifications are available to capture this phenomena, but to date, the class of models most widely used are...

The volatility forecast evaluations most meaningful to forecast users are those conducted under economically relevant loss functions. Although several such loss functions are proposed in the literature, their implied economic costs are of interest only to specific types of volatility forecast...

We estimate two-factor equilibrium models on different parts of the yield curve. In this exploration of the term structure of interest rates, we use two-factor affine yield models as our diagnostic tool. The exercise provides insights on how to reconcile the time-series dynamics of interest...

We estimate and test a model of the U.S. term structure that fits both the time series of interest rates and the cross-sectional shapes of the yield and volatility curves. In the model, three unobserved factors drive a stochastic discount process that prices assets so as to rule out arbitrage...
