Explain how you can use the IS-LM and AD-AS models to predict the future and explain the past.

Expert Solution

The ISLM model is related to the AD-AS set up in that the ISLM equilibriums form the locus of points on the AD curve. The IS curve shifts due to changes in monetary and fiscal policy which in turn causes the AD curve to shift. So for instance if the government uses an expansionery monetary policy through a cut back in interest rates then this allows us to predict in the future that the LM curve will shift rightwards causing a fall in the interest rates and a rise in the output level. Thus the shifts in the LM curve allow a prediction of which way the output level and interest rates will move. Similarly a cut back in taxes through an expansionery fiscal policy will allow a prediction that through an increase in disposable income there will be an increase in output and the interest rates. Thus monetary and fiscal policies will show how IS and LM curves will shift and so help determine the future through changes in the aggregate demand.

Predict, with the aid of the IS-LM and the SAS-AD models, the short-run and long-run results when consumer optimism increases. Assume the economy is initially in long-run equilibrium at the natural real GDP. To receive full credit make sure to do the following: (i) Explain why each curve shifts. (ii) Clearly label the starting equilibrium. (iii) Clearly label at least 2 short-run equilibrium points. (iv) Clearly label the final long-run equilibrium. (v) What happens to the interest rate, output, price...

For the following policy shocks in the US, use the IS-LM models to predict if the situation will cause the interest rate (r) and income (Y) to increase or decrease. 1. Central bank sells large amount of mortgage securities. 2. Government hires more workers, but raises taxes so budget deficit doesn't change. 3. Central bank lowers reserve requirements for commercial banks. 4. Government offers young firms special tax benefits.

Consider a closed economy. Using the IS-LM and AD-AS models, show graphically how a simultaneous increase in taxes and a decline in government spending would affect equilibrium output, interest rates, unemployment rate, and the price level both in the short-run and medium-run. Next, explain the effects (if any) using a time-series graph on the consumption and investment both in the short-run and medium-run. Suppose that the economy starts at the natural level of output. Please label the initial equilibrium with...

Using the IS-LM model and the AD-AS diagram, explain how fluctuations in investors' "animal spirits" may cause business cycles. How would you expect prices and interest rates to behave over the business cycle in this case? (Hint: what would happen to investment demand if investors expected high returns?
