dc.description.abstractEste artigo apresenta um modelo que analisa o grau de autonomia de um Banco central independente, mas comprometidos com determinados objectivos, numa união monetária. Neste modelo, os resultados nominais e reais são determinados pelas interacções entre os diversos agentes, as autoridades políticas supranacionais e o Banco central da união. A informação imperfeita sobre os choques que afectam a oferta, os canais de transmissão e as expectativas de médio prazo podem levar o Banco central a desviar-se dos objectivos propostos. Essa possibilidade de desvio aplica-se a bancos centrais sem condicionantes inflacionárias e empenhados exclusivamente em cumprir um objectivo nominal. Mostra-se que, em determinadas condições, os desvios nominais relativamente aos objectivos propostos não são observáveis pelos agentes nem pela autoridade supranacional que periodicamente selecciona a constituição do Conselho para a Política Monetária do Banco central. Esses desvios aumentam a variação dos valores nominais, mas diminuem as flutuações do rendimento real. Os resultados confirmam obtidos confirmam a posição defendida por Cukierman e Metzler sobre a eficiência de um comportamento ambíguo de um Banco central, neste caso numa união monetária.por
dc.description.abstractCet article présente un modèle qui analyse le degré d'autonomie, dans une union monétaire, d'une Banque centrale indépendante mais engagée. Dans ce modèle, les résultats nominaux et réels sont déterminés par les interactions des différents agents, les autorités politiques supranationales et la Banque centrale. L'imperfection de l'information sur les chocs qui affectent l'offre, les voies de transmission et les anticipations à court terme peuvent mener la Banque à s'écarter des objectifs annoncés. C'est surtout les banques centrales sans contraintes inflationnistes et exclusivement engagées dans la réalisation d'un objectif nominal qui sont susceptibles de présenter cet écart. On montre que dans certaines conditions les écarts nominaux par rapport aux objectifs proposés ne sont pas observables par les agents ni par l'autorité supranationale qui périodiquement sélectionne la composition du Conseil pour la politique monétaire de la Banque centrale. Ces écarts augmentent la variation des valeurs nominales, mais diminuent les fluctuations du revenu réel. Les résultats confirment la position défendue par Cukierman et Metzler sur l'efficience d'un comportement ambigu d'une banque centrale, dans ce cas dans une union monétaire.fra
dc.description.abstractThe paper presents a model analyzing the degrees of freedom of an independent but committed Central Bank within a monetary union. In the model, interactions between Agents, Supranational Political Authorities and the Central Bank of the Union determine the current nominal and real outcomes. Imperfectly distributed information on shocks affecting supply, transmission channels and short-term expectations create opportunities for a Central Bank to deviate from its announced objective. This opportunity to deviate especially applies to Central Banks free from any kind of inflationary bias and committed to a strictly nominal target. Under certain conditions we show that nominal deviations from stated targets are not observable either by Agents or the Supranational Political Authority that periodically selects the membership of the Council of Monetary Policy of the Bank. Those deviations increase the variance of nominal values but dampen fluctuations of real income. Our results confirm, within a monetary union, the position defended by Cukierman and Metzler concerning the efficiency of a Central Bank’s ambiguous behaviour.eng
