AnalysisMediumIS Curve Derivation

Explain step by step how to graphically derive the IS curve using the goods market equilibrium (Keynesian cross / aggregate demand diagram). Describe the changes in output that result from a change in the interest rate and how these points translate into the IS space.

Why

Write your answer, then tap Show model answer. The model answer and marking points will appear here.

Compare with your answer.

Model answer. 1. Start with the goods market diagram (aggregate demand Z against output Y with the 45-degree line Y = Z). For an initial interest rate i, aggregate demand intersects the 45-degree line at point A, corresponding to output Y.
2. In a panel directly below, plot the interest rate i on the vertical axis and output Y on the horizontal axis. Plot point A at coordinates (Y, i).
3. Suppose the interest rate increases from i to i'. Because investment depends negatively on the interest rate, higher borrowing costs reduce investment spending, shifting the aggregate demand curve downward from Z to Z'.
4. The new equilibrium in the goods market occurs at point A', where output falls to Y' due to the multiplier effect.
5. Project this new equilibrium down to the lower diagram to plot point A' at coordinates (Y', i').
6. Connecting points A and A' yields the downward-sloping IS curve, showing that higher interest rates are associated with lower equilibrium levels of output in the goods market.

Identifies the initial goods market equilibrium where aggregate demand intersects the 45-degree line at interest rate i and output Y.
Explains that an increase in the interest rate reduces investment demand, shifting the aggregate demand curve downward.
Identifies the resulting lower equilibrium output level Y' via the multiplier process.
Explains how plotting these pairs (Y, i) and (Y', i') in interest rate-output space traces out a downward-sloping IS curve.

AnalysisHardIS-LM Model

Suppose investment spending depends on output but is completely insensitive to changes in the interest rate. In the IS-LM framework, a reduction in government spending will lead to which of the following outcomes?

Why

Tap an answer. The explanation will appear here, including why each wrong option is wrong.

Not quite. A is correct.

Because investment does not depend on the interest rate, the IS curve is vertical. A cut in government spending reduces aggregate demand and output, which in turn reduces output-dependent investment spending.

A: why it's wrongWith investment insensitive to the interest rate, the IS curve is vertical. A reduction in government spending shifts the IS curve left, causing equilibrium output to decline. Because investment depends positively on output, lower output leads directly to lower investment.

Tap any option to see why it's right or wrong.

Not quite. A is correct.

B: why it's wrongThis incorrectly assumes that fiscal policy has no impact on output when investment is interest-insensitive, whereas goods market equilibrium output falls directly when autonomous spending falls.

Tap any option to see why it's right or wrong.

Not quite. A is correct.

C: why it's wrongThis overlooks the money market response; as output falls, the transaction demand for money decreases, driving down the equilibrium interest rate along the LM curve.

Tap any option to see why it's right or wrong.

Not quite. A is correct.

D: why it's wrongThis confuses fiscal contraction with an effect that promotes private investment through crowding-in, but since investment does not respond to lower interest rates and output falls, investment must fall.
