Based on criteria of mathematical simplicity and consistency with empirical market data, a stochastic volatility model is constructed, the volatility process being driven by fractional noise. Price return statistics and asymptotic behavior are derived from the model and compared with data....

In this paper, we reexamine and extend the stochastic volatility model of Stein and Stein (1991) where volatility follows a mean-reversion Ornstein-Uhlenbeck process. Using Fourier inversion techniques we are able to allow for correlation between instan-taneous volatilities and the underlying...

There is much discussion about derivatives at central banks. The main focus is on questions about the impact of the growing use of derivative instruments on the stability of the financial markets and the effectiveness ofmonetary policy measures. Irrespective ofthe answers, the information...
