Document Summary

Is curve shifts right by [1/(1-mpc)]* g causing output & income to rise: this raises money demand, causing the interest rate to rise , which reduces investment, so the final increase in y is smaller than [1/(1-mpc)]* g. A tax cut: consumers save (1-mpc) of the tax cut, so the initial boost in spending is smaller for t than for an equal g and the is curve shifts by: So the effects on r and y are smaller for t and for an equal g. Monetary policy: an increase in m: m > 0 shifts the lm curve down (or to the right) Which increases investment, causing output & income to rise. Is shifts left, causing r and y to fall: c falls due to lower wealth and lower income, u rises because y is lower (okun"s law) Intuition for slope of ad curve: (cid:313)p (cid:314) (cid:315)(m/p) (cid:314) lm shifts left.

Consider the Following Economy:

Y = (C + I + G + NX) <-Income Identity

C = 300*0.8YD<-Consumption

I = 200-1500r <-investment

NX = 100-0.04Y-500r <-net exports

M^d = (0.5Y-2000r) <-Money Demand

G = 1200

t (tax rate) = 0.2

Money Supply (M^s) = $550

P = $1

a. What is the IS Curve?

b. What is the LM Curve?

c. What are the values of Y (income) and interest rate (r) when the IS-LM model is in equilibrium?

Y = (C + I + G + NX) <-Income Identity

C = 300*0.8YD<-Consumption

I = 200-1500r <-investment

NX = 100-0.04Y-500r <-net exports

M^d = (0.5Y-2000r) <-Money Demand

G = 1200

t (tax rate) = 0.2

Money Supply (M^s) = $500

P = $1

Note that C is given as C = 300 + 0.8YD â 1,000r. This consumption will be used to find the following:

a. What is the IS Curve under these assumptions?

b.What are the values of income (Y) and the interest rate (r) when the IS-LM model is in equilibrium?
