Exchange Rate Regimes and Inflation : Only Hard Pegs Make a Difference

Using data from a large sample of developing countries from 1985 to 2001, we confirm that hard pegs (currency boards or a shared currency) reduce inflation and money growth. There is no evidence that soft pegs confer any monetary discipline, after other factors are controlled for. Inflation triggers regime switches. Under hard pegs, monetary growth is unaffected by fiscal deficits or by inflation shocks. Under soft pegs, as under floats, increased fiscal deficits and positive inflation shocks are associated with higher monetary growth. The apparently slower per capita output growth under hard pegs is explained by their geographical distribution
