It clarifies the relationship between uncertainty of inflation persistence and optimal monetary policy and discusses the consequences of the recent Blanchard proposal to implement a higher inflation target in the light of parameter uncertainty. Furthermore, it provides insights of general interest on the methodological level by analyzing the interrelations between normalization of variables and their independence properties and by extending standard solution methods of dynamic programming problems to non-orthogonal parameter uncertainty.
