Recent developments allow a nonparametric separation of the continuous sample path component and the jump component of realized volatility. The jump component has very different time series properties than the continuous component, and accounting for this allows improved forecasting of future...

This paper provides empirical evidence that volatility markets are integrated through the time-varying term structure of variance risk premia. These risk premia predict the returns from selling volatility for different horizons, maturities, and products, including variance swaps, straddles, and...

Treasury stock and firm market value using a modified Tobin's q are modeled by using a firm utility preference function and a quadratic constraint function. The choice of the quadratic form is based on an econometric analysis of the relationship of q to T, the amount of treasury stock held by...
