This paper explores the implications of a new theory of price determination (due to Leeper, Woodford and Sims) for the maintenance of various exchange rate systems – crawling pegs, fixed pegs, and common currency areas. It shows that deeper monetary integration requires more fiscal discipline,...

Using a general-equilibrium simulation model featuring nominal rigidities and monopolistic competition in product and labour markets, this Paper estimates the macroeconomic benefits and international spillovers of an increase in competition. After calibrating the model to the euro area vs. the...

Extending recent theoretical contributions on sources of inflation inertia, we argue that monetary policy uncertainty helps determine the sluggish adjustment of expectations to nominal disturbances. Estimating a model in which rational individuals learn over time about shifts in US monetary...

This Paper proposes a markedly different transmission from monetary policy to the macroeconomy, focusing on how policy changes nominal inertia in the Phillips curve. Using recent theoretical developments, we examine the properties of a small, estimated US monetary model distinguishing four...

While overall inflation has fallen dramatically in countries like Italy and Spain, inflation in the home good sector remains stubbornly higher than inflation in the traded good sector. If nominal exchange rates are fixed, these real appreciations imply an inflation differential with countries...

A new theory of price determination suggests that if primary surpluses are independent of the level of debt, the price level has to ‘jump’ to assure fiscal solvency. In this regime (which we call fiscal dominant), monetary policy has to work through seignorage to control the price level. If,...
