In this paper, we modify Duan’s (1995) local risk-neutral valuation relationship (mLRNVR) for the GARCH option-pricing models. In our mLRNVR, the conditional variances under two measures are designed to be different and the variance process is more persistent in the risk-neutral measure than...

In this paper, we investigate a two-factor VIX model with infinite-activity jumps, which is a more realistic way to reduce errors in pricing VIX derivatives, compared with Mencía and Sentana (2013). Our two-factor model features central tendency, stochastic volatility and infinite-activity pure...

This paper investigates spatial linkages in returns, idiosyncratic risks, and volatilities across nineteen U.S. regional housing markets. Using Case & Shiller housing price indices from 1995 through 2009, we find that interconnections across markets can be “wider” and “stronger” than...

This paper models the correlated shocks across regional housing markets and the spillover effects in time-varying housing price volatilities. We explore two kinds of diffusion channels: geographic closeness and economic similarity. Our empirical investigation is based on the Case-Shiller housing...
