Abstract
In this paper, we analyze the e¤ectiveness of the direct central bank interventions using a new effectiveness criterion. To this aim, we investigate the e¤ects of central bank interventions (CBI) in a noise trading model with chartists and fundamentalists. We ?rst estimate a model in which chartists extrapolate past returns and fundamentalists forecast a mean reverting dynamics of the exchange rate towards a fundamental value. Then, we investigate the role of central bank interventions for explaining the switching properties between the two types of agents. We ?nd evidence that in the medium run, interventions increase the proportion of fundamentalists and therefore exert some stabilizing in?uence on the exchange rate.
