# IS/LM diagram

1. Draw an IS/LM diagram which shows a macro equilibrium (use the â??intermediate range for the LM curve --- assuming the absolute value of lâ?? is less than infinity and greater than 0). Indicate the equilibrium interest rate by ro, and the equilibrium level of income by yo.

2 . Now suppose there is an increase in government spending financed by the Treasury selling bonds to the public (a pure fiscal policy).

a) Show the appropriate shifts in the IS and/or LM curve in the above diagram.

b) Indicate the new equilibrium income and interest rate by y1 and r1.

c) State what has happened to equilibrium income and interest rates.

d) Is the level of investment spending higher or lower than at ro,yo?

e) Has money demand changed? If so, how?

f) If the LM curve had been totally inelastic (lâ??=0) with respect to interest rates (vertical) would your answers to b) and e) change? If so, how and why.

1. Draw an IS/LM diagram which shows a macro equilibrium (use the â??intermediate range for the LM curve --- assuming the absolute value of lâ?? is less than infinity and greater than 0). Indicate the equilibrium interest rate by ro, and the equilibrium level of income by yo.

Please see figure 1 in the attachment.

2 . Now suppose there is an increase in government spending financed by the Treasury selling bonds to the public (a pure fiscal policy).

a) Show the appropriate shifts in the IS and/or LM curve in the above diagram.

A pure fiscal policy means that the government is increasing the national deficit. This shifts the IS curve to the right. (Please see figure 2 in the attachment. The reason for this shift is that ...
