• Time-Varying Crash Risk: The Role of Stock Market Liquidity

  Staff Working Paper 2016-35 Peter Christoffersen, Bruno Feunou, Yoontae Jeon, Chayawat Ornthanalai

  We estimate a continuous-time model with stochastic volatility and dynamic crash probability for the S&P 500 index and find that market illiquidity dominates other factors in explaining the stock market crash risk. While the crash probability is time-varying, its dynamic depends only weakly on return variance once we include market illiquidity as an economic variable in the model.

• Option Valuation with Observable Volatility and Jump Dynamics

  Staff Working Paper 2015-39 Peter Christoffersen, Bruno Feunou, Yoontae Jeon

  Under very general conditions, the total quadratic variation of a jump-diffusion process can be decomposed into diffusive volatility and squared jump variation. We use this result to develop a new option valuation model in which the underlying asset price exhibits volatility and jump intensity dynamics.

• The Economic Value of Realized Volatility: Using High-Frequency Returns for Option Valuation

  Staff Working Paper 2012-34 Peter Christoffersen, Bruno Feunou, Kris Jacobs, Nour Meddahi

  Many studies have documented that daily realized volatility estimates based on intraday returns provide volatility forecasts that are superior to forecasts constructed from daily returns only. We investigate whether these forecasting improvements translate into economic value added.
