Le premier, que I'identification de la monnaie avec I'or emp6che Ricardo de saisir le sens du papier-monnaie et, par consequent de comprendre pleinement ses propri6t6s. Le deuxieme, que Ricardo est le champion de la th6orie quantitative de la monnaie et qu'il refuse de voir les effets reels des variations dans les variables nominales. Le troisieme, que Ricardo porte une attention exclusive aux p,hnomenes permanents au d6triment de I'analyse des phenomenes a court terme. Notre analyse affronte ces reproches et propose une interpr6tation alternative de la theorie mon6taire de Ricardo.
MISUNDERSTANDINGS According to Hicks [1967], classical monetary theory has two main strands, one represented by Ricardo and the Currency School, who believed in relying at all costs (including deflation and unemployment) on automatic regulation of the quantity of money, the other stream by Thornton and Tooke, who favoured a permissive monetary policy and were prepared to accept a little monetary instability as the price of sustaining the level of economic activity and insulating the domestic economy from fluctuations in the balance of payments.Clearly this interpretation reflects the general acceptance of the Keynesian approach to monetary theory in those years, when Ricardo "was that able but wrong-headed man" who "shunted the car" of monetary theory on to a wrong line. On the contrary, Thomton is the economist who understood that "money matters": a monetary economy is governed by uncertainty; in monetary affairs discretion is preferable to rules, since the economy is hardly ever in full equilibrium and the equilibrating forces of market mechanisms are slow or ineffective .
