Assume the following IS-LM model: expenditure sector: money sector: &n

Assume the following IS-LM model:

expenditure sector: money sector:

AD = C + I + G + NX M_s = 500

C = 110 + (2/3)YD P = 1

YD = Y - TA + TR m_d = (1/2)Y + 400 - 20i

TA = (1/4)Y + 20

TR = 80

I = 250 - 5i

G = 130

NX = -30

Calculate the equilibrium values of private domestic investment (I), tax revenues (TA), and real money demand (m_d).

How much of private domestic investment (I) will be crowded out if government purchases are increased by DG = 100?

Expert Solution

Solution:

a.)

From Y=AD ==>

IS-curve

From

From IS = LM

b)

If government purchases are increased by , the IS-curve will shift by

,

and the new IS-curve is of the form Y=1200-10i

Therefore, fro IS1=LM

Check: I1 = 250-5*20=150

** I hope you understand the solution. If yes then please rate me up. If not then please comment for solving doubt. And don’t forget to Rate.

In an IS-LM model, if we assume that money demand is completely insensitive to changes in the interest rate A.) interest rates cannot be lowered by fiscal policy B.) fiscal policy can neither change the level of output nor the composition of GDP C.) monetary policy can change income D.) monetary policy is totally ineffective in changing the rate of interest E.) the economy cannot be stimulated by fiscal or monetary policy

Assume the Fed decided to decrease money supply. Using the IS/LM model along with the aggregate demand, aggregate supply, verbally explain what will happen to the Price level, Output, Consumption, Unemployment and interest rate in both the short run and long run. Verbally state the movements and shifts in the curves. Make sure to explain how the economy transitions form the short run to the long run.

2 LM model: thought experiment: Use money market equilibrium to graphically show how LM curve shift in following cases: (1) the Fed decide to sell government bonds this year; (2) the public’s inflation expection rises because one of the Fed officials told the media that the Fed will increase the money supply significantly next year in 2019. (3) real GDP increases because technology improves.

Assume that the IS-LM-BP model is an accurate abstraction of a real economy, and use the model to describe how the macroeconomic effects of a tightening of monetary policy differ between a closed economy and an open economy. Hint: be sure to first describe the IS-LM-BP model, and then show how fiscal policy shifts the curves and the economy reached a new equilibrium.
