This paper studies the effect on monetary policy of a non-homogeneous degree of competition across the (two) members of a monetary union. In particular, we assess the welfare loss brought about by the use of a simple interest rate rule that does not take into account such structural differences....

A two-country sticky-price model is used to analyse the interactions between fiscal and monetary policy. The role of an u0091activistu0092 fiscal policy as a stabilisation tool is considered and a measure of the welfare gains from international fiscal policy cooperation is derived. It is found...

We use a version of the New Area-Wide Model (NAWM) developed at the ECB in order to quantify the gains from monetary policy cooperation. The model is calibrated in order to match a set of empirical moments. We then derive the cooperative and (open-loop) Nash monetary policies, assuming that the...

We examine global economic dynamics under learning in a New Keynesian model in which the interest-rate rule is subject to the zero lower bound. Under normal monetary and fiscal policy, the intended steady state is locally but not globally stable. Large pessimistic shocks to expectations can lead...

A growing number of papers have studied positive and normative implications of financial frictions in DSGE models. We contribute to this literature by studying the welfare-based monetary policy in a two-country model characterized by financial frictions, alongside a number of key features, like...

We show that the composition of imports has important implications for the optimal volatility of the exchange rate. Using input-output data for 25 countries we document substantial differences in the import and non-tradable content of final demand components, and in the role played by imported...

We study how the use of judgement or add-factorsʺ in macroeconomic forecasting may disturb the set of equilibrium outcomes when agents learn using recursive methods. We isolate conditions under which new phenomena, which we call exuberance equilibria, can exist in standard macroeconomic...

This paper studies the implication, in terms of welfare and monetary policy, of unequal degrees of competition across members of a currency area. We look at two ways in which the degree of competition in the market for goods can affect welfare in a currency area. One is through different average...
