Effect of Monetary Intervention in the Frame of IS-LM Model with Dynamic Price Adjustment and Adaptive Expectations

An assumption that a central bank can influence the real interest rates is the object of our interest. In the paper we form and solve a model which corresponds to Romer´s (2000) assumptions. Our model is IS-LM augmented by a conception of price-adjusting after monetary intervention and inflation expectations. A monetary policy rule is derived from the model. Moreover, it offers a demonstration of economic behaviour by different economic assumptions of different economic schools, similar to one in the book of Heijdra (2002).
