          Abstract

          As reputation and credibility are important elements for monetary policy effectiveness, the paper aims at exploring the concepts of both and its importance in a context where central banks policies are not neutral, that is, monetary policy affects real and nominal variables. The paper seeks to contribute with a new analysis of how the sort of reputation developed by the monetary authority affects the state of expectations, and then the economic performance, enabling a particular situation that we call "credibility trap" - which makes monetary policy ineffective to affect real activity when necessary. Although the paper presents some similarities to the orthodox approach regarding both reputation and credibility's importance for central banks and its policies, it is different from the orthodox approach speaking of distinct forms of monetary policy recommendations and the sort of reputation that it recommends to be developed.

          Translated abstract

          Como reputação e credibilidade são importantes elementos para a eficácia da política monetária, o trabalho explora os conceitos de ambos e suas importâncias em um contexto em que as políticas dos bancos centrais não são neutras, sendo capazes de afetar variáveis reais e nominais. O trabalho busca contribuir com uma nova análise de como o tipo de reputação desenvolvido pela autoridade monetária afeta o estado de expectativas e, assim, o desempenho econômico, possibilitando um caso particular que chamaremos de "armadilha de credibilidade" - a qual torna a política monetária ineficaz em afetar a atividade econômica real quando necessário. Embora a abordagem proposta pelo trabalho apresente algumas similaridades com a abordagem ortodoxa acerca da importância da reputação e da credibilidade para os bancos centrais e suas políticas, a abordagem distingue-se da ortodoxa em termos de recomendações de política monetária e do tipo de reputação que deve ser desenvolvida.
