What happens when government spending is increased?
The relative lengths of the

blue arrows is governed by the spending multiplier.

Слайд 6

But the actual change in

income is affected by the “crowding out” of investment.

rightward, lowering interest rates.

Слайд 12

The LM curve shifts

rightward, lowering interest rates.

Note that the multiplier applies to the interest-induced change in investment.

Because of the inelasticity of investment demand, monetary policy is relatively ineffective.

ISLM analysis builds upon the simple Keynesian Income-Expenditure relationships by adding

interest-rate considerations.
Using this analysis, we see that the multiplier effect is sometimes not as great as the simple multipliers imply, owing to a change in the rate of interest and hence a movement along the demand for investment funds.
In a number of applications, however, the simple multipliers do apply.
That is, ΔY = [1/(1 - b)] ΔI
ΔY = [1/(1 - b)] ΔG
or ΔY = [1/(1 - b)] ΔENET
where ΔENET is the net change (ΔG - ΔI) in autonomous expenditures.

Слайд 57

Examples of conditions or instances in which the simple Keynesian spending

multiplier applies include:

An economy mired in the liquidity trap, in which case the interest rate does not change.
An economy with a perfectly inelastic demand for investment funds, in which case the changing interest rate has no effect on investment.
An instance where fiscal policy is fully accommodated by monetary policy, in which case any movement in the rate of interest is arrested by a suitable adjustment in the supply of money.

Слайд 58

Examples of conditions or instances in which the simple Keynesian spending

multiplier applies include:

An instance where the initial round of spending is pre-adjusted for the expected "crowding out" of investment. This is the application, mentioned above, where the simple multiplier is applied to the net change in autonomous expenditures.
An instances where the issue is the extent of the shift of the IS curve in response to a given shift in investment demand or increase in government spending. Of course, the increase in income, ΔY, may not be as great as the actual shift in IS, owing the interest-rate effect on investment.
An instance where an increase in the money supply lowers the interest rate and stimulates investment. Here, the ΔY (associated with a movement along the unshifted IS curve) is related to the ΔI (associated with a movement along the unshifted investment demand curve) by the simple Keynesian spending multiplier.

Слайд 59

The question "Can I use the simple Keynesian multiplier to calculate

the effect of X on income" resolves itself into a sequence of subsidiary questions:
Does X affect the interest rate? If no, then use the simple Keynesian multiplier. If yes, then go on to question 2.
2. Does the change in the interest rate affect investment? If no, then use the simple Keynesian multiplier. If yes, then go on to question 3.
3. Is the interest-rate-induced change in investment taken into account? If yes, then use the simple Keynesian multiplier.
