IS-LM model of aggregate demand There is another major model that is useful for explaining the nature of the aggregate demand curve. This model is called the IS-LM model after the two curves that are involved in the model. The IS curve describes equilibrium in the market for goods and services where Y = C(Y - T) + I(r) + G and the LM curve describes equilibrium in the money market where M/P = L(r,Y). The IS-LM model exists in a plane with r, the interest rate, on the vertical axis and Y, being both income and output, on the horizontal axis. The IS-LM model has the same horizontal axis as the aggregate demand curve, but a different vertical axis. Figure %: Graph of the IS-LM curves. The IS curve describes equilibrium in the market for goods and services in terms of r and Y. The IS curve is downward sloping because as the interest rate falls, investment increases, thus increasing output. The LM curve describes equilibrium in the market for money. The LM curve

The intersection of the IS curve with the LM curve shows the equilibrium interest rate and price level. The IS curve and the LM curve shift in response to economic activities. The IS curve shifts outward as a result of increased government purchases, exogenous increases in investment, decreases in taxes, and exogenous increases in consumption. The IS curve shifts inward as a result of decreases in government purchases, exogenous decreases in investment, increases in taxes, and exogenous decreases in consumption. The LM curve shifts outward as a result of increases in the money supply and decreases in the price level.
