This paper shows that if the cost of importing foreign inflation and real exchange rate shocks are not too high, then the equilibrium nominal exchange rate regime for a country with a credibility problem is a peg, under which credibility is higher and inflation is lower than under a float. This holds true although devaluations of the pegged rate are assumed to be costless. The reason is that as realized inflation is not perfectly controllable, planned inflation under a float is private information. In contrast, since the exchange rate can be perfectly controlled, pegging resolves the private information problem, is more transparent, and makes reputation more effective.
