Topic 1: The Open Economy (IS-LM-BP) (Melvin & Norrbin Ch. • Comparative statics: – Changes in autonomous spending. A given price level P ﬁxes the real money supply M / P, which sets the LM curve.

The real money supply gradually declines to the original value. It is worth noting that in the IS-LM model increase in national income by Y 1 Y 2 in Fig. – As interest rates rise, output falls. Macroeconomics Keynesian IS-LM Model Aggregate Demand Curve The aggregate demand curve is a construction derived from the IS-LM model. The national income and product determined by the IS-LM intersection can then be seen as a decreasing function of P.If P An … IS-LM model takes into account the fall in private investment due to the rise in interest rate that takes place with the increase in Government expenditure. Therefore, the real money supply is unchanged. Dr. Nick Zammit (Warwick) Topic 1 July 25, 2016 2 / 53 Notes Notes The assumption can be dropped anytime by adding an aggregate supply curve to the IS-LM model which distributes changes in aggregate demand between changes in the price level P and changes in output Y (IS-LM-AS model).
