Sudden and protracted oil-price increases are generally accompanied by economic contractions and high inflation. How should monetary policy react to oil-price shocks in order to minimize such adverse macroeconomic effects? We build a DSGE model characterized by two oil-importing countries and...

Monetary policy is sometimes formulated in terms of a target level of inflation, a fixed time horizon and a constant interest rate that is anticipated to achieve the target at the specified horizon. These requirements lead to constant interest rate (CIR) instrument rules. Using the standard New...

Recently, several countries have been considered the relative merits of "dollarization", that is, adopting the currency of an anchor country. One of the main potential costs of dollarization is that macroeconomic stability may be reduced by the loss of monetary policy autonomy. In this paper, we...

Contract structures typically embedded in a recent generation of models with nominal inertia have been criticized for a failure to generate persistent responses of output and inflation to nominal shocks. In this paper, we argue that this failure does not reflect an inherent limitation of the...

This paper aims at suggesting a simple prototype model that describes the complex dynamics of a sophisticated monetary economy. The interaction between the current and intertemporal financial constraints of economic units brings about irregular fluctuations at the micro and macro levels. By...

We study optimal monetary policy in a two-sector model. The conventional wisdom in the literature is that the monetary authority should optimally stabilize inflation in the sticky-price sector. We reassess this issue in a two sector economy with capital accumulation subject to adjustment costs....

We evaluate the case for perfect price (inflation) stabilization in a New Keynesian (NNS) model that includes capital accumulation, a variety of shocks, a monetary and an imperfect competition distortion. In such a model, price rigidity may provide the monetary authorities with an opportunity to...

The natural rate of interest -- the real interest rate consistent with output equaling potential -- plays an important role in both economic forecasting and monetary policy. Much of the literature has assumed that the natural rate of interest is constant. For example, the Taylor rule includes a...
