We estimate the macroeconomic benefits and international spillovers of an increase in competition using a general-equilibrium simulation model with nominal rigidities and monopolistic competition in product and labor markets. We draw three conclusions after calibrating the model to the euro area...

This paper provides an introduction to the recent literature on macroeconomic stabilization in closed and open economies. We present a stylized theoretical framework, illustrating its main properties with the help of an intuitive graphical apparatus. Among the issues we discuss are optimal...

The paper considers the macroeconomic transmission of demand and supply shocks in an open economy under alternative assumptions about whether the zero interest rate floor (ZIF) is binding. It uses a two-country general-equilibrium simulation model calibrated to the Japanese economy relative to...

The financial crisis has prompted macroeconomists to think of new policy instruments that could help ensure financial stability. Policymakers are interested in understanding how these should be set in conjunction with monetary policy. We contribute to this debate by analyzing how monetary and...

Emerging market economies often face sudden stops in capital inflows or reduced access to the international capital market. This paper analyzes what monetary policy should accomplish in such an event. Optimal monetary policy induces higher interest rates and exchange rate depreciation. The...
