This paper studies a classical extension of the Black and Scholes model of option pricing, often known as the Hull and White model. Our specificity is that the volatility process is assumed not only to be stochastic, but also to have long memory features and properties. We study here the...

This paper, prepared for the Invited Symposium "Financial Econometrics" at the 7th WCES, Tokyo, August 1995, surveys the subject of Econometrics of option pricing, and more precisely try to offer versatile tools to model the source of the prediction errors in option pricing.

We consider a nonparametric random design regression model in which the response variable is possibly right censored. The aim of this paper is to estimate the conditional destribution function and the conditional x-quantile of the response variable. We restrict attention to the case where the...

The infinite source Poisson model is a fluid queue approximation of network data transmission that assumes that sources begin constant rate transmissions of data at Poisson time points for random lengths of time. This model has been a popular one as analysts attempt to provide explantations for...

We introduce non-nested hypothesis tests using indirect simulation-based estimation procedures.

We consider truncated processes, both in discrete and continuous time, and study their dynamic properties. When the underlying process is a diffusion process, we derive the infinitesimal generator of its truncated counterpart. This result is the basis for the estimation of the drift and...

We analyse high-frequency data by means of the duration between successive ticks and volume of capital durations. It allows to introduce trading activity and coactivity measures, which may or may not also be volume weighted. Some applications on particular stocks of the PAris Bourse are provided.
