Our focus is to appraise the welfare of a country, which belongs to a monetary union and might suffer a speculative attack on its public debt. A default may...

We study the interplay between the central bank transparency, its credibility, and the inflation target level. Based on a model developed in the spirit of the global games literature, we argue that whenever a weak central bank adopts a high degree of transparency and a low target level, a bad...
