Modeling the interdependence of volatility and inter-transaction duration processes

Grammig, Joachim; Wellner, Marc - 1999

simultaneous estimation of the interdependent duration-volatility model. In an empirical application we utilize the model for an … indirect test of the hypothesis that volatility is caused by private information that affects prices when informed investors … trade. The result that volatility shocks significantly increase expected inter-transaction durations supports this …

Financial price fluctuations in a stock market model with many interacting agents

Horst, Ulrich - 2001

We consider a financial market model with a large number of interacting agents. Investors are heterogeneous in their expectations about the future evolution of an asset price process. Their current expectation is based on the previous states of their "neighbors" and on a random signal about the...

Modelling exchange rates volatility with multivariate long-memory ARCH processes

Teyssière, Gilles - 1999 - Rev.

We consider two multivariate long-memory ARCH models, which extend the univariate long-memory ARCH models, we first consider a long-memory extension of the restricted constant conditional correlations (CCC) model introduced by Bollerslev (1990), and we propose a new unrestricted conditional...

Malliavin's calculus in insider models : additional utility and free lunches

Imkeller, Peter - 2002

We consider simple models of financial markets with regular traders and insiders possessing some extra information hidden in a random variable which is accessible to the regular trader only at the end of the trading interval. The problems we focus on are the calculation of the additional utility...
