1Some versions of this model use the price level instead of the inflation rate to make the model more consistent with its microeconomics counterpart Using the inflation rate as is done here produces results that are a little more realistic Figure 2 1 CHAPTER 2 THE AGGREGATE SUPPLY AGGREGATE DEMAND MODEL
Unlike the aggregate demand curve the aggregate supply curve does not usually shift independently This is because the equation for the aggregate supply curve contains no terms that are indirectly related to either the price level or output Instead the equation for aggregate supply contains only terms derived from the nbsp
