We study optimal monetary policy for a small open economy in a model where both domestic prices and wages are sticky due to staggered contracts. The simultaneous presence of the two forms of nominal rigidities introduces an additional trade-off between domestic inflation and the output gap. We derive a second-order approximation to the average welfare losses that can be expressed in terms of th...

Introduction Nowadays, interventional cardiology brought a great success to the treatment of many cardiovascular disorders. Despite these great beneficial effects, it has side effects related to the applied techniques. Among them, inflation pressure and pattern of inflation play fundamental role in this regard. By low and very high inflation pressures, the rate of stent thrombosis and in-stent ...

Oil price shocks are the main source of macroeconomic fluctuations in oil exporting countries. It is believed that appropriate monetary policy can help to stabilize these unwanted variations toward optimal allocations. A stochastic dynamic general equilibrium model featuring the properties of both cost push and wealth effect transmission channels is developed for the Iranian economy. In thi...

The EMU accession countries are obliged to fulfill the Maastricht convergence criteria prior to entering the EMU. What should be the optimal monetary policy satisfying these criteria? To answer this question, the paper proposes a DSGE model of a two-sector small open economy. First, I derive the micro founded loss function that represents the objective function of the optimal monetary policy no...

The paper examines optimal monetary policy delegation in an economy where wages are set strategically by a single economy-wide union whose objectives relate to employment and the real wage. Crucially, the central bank exerts imprecise control over inflation, giving rise to a positive relationship between the mean value of inflation and its variance. In this context, union concerns with regard t...

I develop an extension of the standard New Keynesian model to monetary policy regime switching to study the impact of uncertainty around the future inflation target. First, I fully characterize how the responses of current inflation and output to inflation target uncertainty depend on the monetary policy rule. If monetary policy is passive, inflation may increase far beyond the anticipated incr...

We characterize the Ramsey optimal rate of inflation in a model with a foreign demand for domestic currency. In the absence of such demand, the model implies that the Friedman rule—deflation at the real rate of interest— is optimal. We show analytically that in the presence of a foreign demand for domestic currency, this result breaks down. Calibrated versions of the model deliver optimal annua...

How do financial frictions affect the optimal inflation rate? Can financial frictions alone annul the long-run super-neutrality of money? Should the inflation rate be higher in emerging market economies with less developed financial markets than in advanced economies, as is currently observed? To answer these questions we set up an incomplete markets model in which households choose portfolios ...
