We analyze the effect of inflation on the average output of monopolistic firms facing a small fixed cost of changing nominal prices. Using Taylor expansions, we derive a general closed-form solution for the slope of the long-run Phillips curve. This very simple, unifying formula allows us to...

The conditions of the `new EMS' - an absence of exchange rate realignments and corresponding added credibility - have given rise to concern about the stabilization properties of the System. Nominal interest rate divergence may have been narrowed ahead of inflation divergence. Cross-country real...

Recent empirical tests of dynamic optimal seigniorage models focus on their `smoothing' and long-run implications. The models also imply that the optimal policies are forward looking; that is seigniorage revenues depend on expected future government expenditures. We report causality tests of...
