This paper is one of four in this Working Paper series, focusing on financial liberalisation, along with those by Miller and Weller, Driscoll, and Blundell-Wignall and Browne. It examines the historical volatilities of stock, bond and foreign currency markets over alternative periods differing roughly by the degree of financial innovation and globalisation.

Le présent document constitue l'une des quatre études de cette Série consacrée à la libéralisation financière avec celles de Miller et Weller, de Driscoll, et de Blundell-Wignall et Browne. Il examine le concept de volatilité historique observée sur les marchés d'actions, d'obligations et de change au cours de plusieurs périodes caractérisées par un état d'avancement différent du processus d'innovation et de globalisation financière. Il cherche à caractériser les tendances de la volatilité brute, l'ampleur et la forme des changements survenus dans la volatilité sur les marchés financiers, les conséquences sur l'économie réelle des périodes temporaires de volatilité excessives.
