The paper examines how rules and institutions as well as the monetary-fiscal coordination setup impact welfare outcomes of a reform during uncertainty shocks. We define uncertainty shocks as sudden events that create ambiguity about future course of economic policies chosen by policy makers as...

We present determinacy bounds on monetary policy in the sticky information model. We find that these bounds are more conservative here when the long run Phillips curve is vertical than in the standard Calvo sticky price New Keynesian model. Specifically, the Taylor principle is now necessary...

The monetary integration of the acceding countries will proceed in several distinct steps, starting with membership in the European Union (EU), followed by participation in the so-called Exchange Rate Mechanism (ERM) II and ultimately entry into the euro area. This paper addresses the question...

This paper assesses the role of sovereign risk in explaining macroeconomic fluctuations in Turkey. We estimate two versions of a simple New Keynesian small open economy model on quarterly data for the period 1994Q3-2008Q2: A basic version and a version augmented by a default premium on...

Does fiscal policy have qualitatively different effects on the economy in a liquidity trap? We analyze a nonlinear stochastic New Keynesian model and compare the true and loglinearized equilibria. Using the loglinearized equilibrium conditions, the answer to the above question is yes. However,...

Recent macro developments in the euro area have highlighted the interactions between fiscal policy, sovereign debt, and financial fragility. We take a structural macroeconomic model with frictions in the financial intermediation process, in line with recent research, but introduce asset choice...

In this paper we study fiscal policy effects and fiscal space for countries in a monetary union with different levels of public debt. We develop a dynamic stochastic general equilibrium (DSGE) model of a two-country monetary union, calibrated to match the characteristics of Spain and Germany, in...
