Dans le cas univarié l'existence de la prime instantanée de liquidité est démontrée, ceci indépendamment de toute spécification du modéle ; ce taux donne une mesure quantitative de la stabilité du marché. Nous établissons une formule mathématique donnant la prime instantanée de liquidité en terms de termes de volatilités itérées, qui, pour les valeurs objets d'un nombre élevé de cotations, sont économétriquement mesurables.
In the univariate case we show mathematical existence, in real time and model free, of the instantaneous liquidity rate, which is a measure of the market stability. We give a mathematical formula expressing the instantaneous liquidity rate in terms of self cross volatilities, which, for frequently traded assets, are econometrically measurable.
