		| The goal of this paper is to extend the model of Cecchetti and Ehrmann 2000 to study the case of developing countries that have a constraint in conducting their monetary policies. Contrary to Cecchetti and Ehrmann 2000 model, our model shows that the existence of such a constraint i.e. cost restriction allows the aggregate demand shock to affect the output-inflation variability. Our model also shows that adding a monetary policy cost restriction to the central bank loss function leads to either a steeper or flatter efficient frontier. This implies that the effect of monetary policy to offset aggregate demand and supply shocks is reduced. |
