Tiivistelmä: | This paper extends the class of stochastic volatility diffusions for asset returns to encompass Poisson jumps of time-varying intensity. The authors find that any reasonably descriptive continous-time model for equity-index returns must allow for discrete jumps as well as stochastic volatility with a pronounced negative relationship between return and volatility innovations. |
