So here we have an is -lm model, and we've got an is -lm model where both the is and the lm curves are shifting.
00:06
So we have a fairly complicated situation.
00:09
Again, interest rate and output.
00:11
The lm curve is shifting up, it looks like.
00:14
So we have lm0, and i'll use color for this, lm1.
00:19
The is curve, however, is also shifting out.
00:24
Okay, so is0, and here's my original a equilibrium.
00:29
And then we have is one okay then we have over here of course that with the higher interest rate we have a change in the exchange rate right so when the interest rate goes up the exchange rate is going up as well gotcha okay so this is increasing by government spending that's government spending and if if government spending increases without increasing the interest rate.
01:11
Okay.
01:12
A is wrong.
01:15
A is wrong.
01:17
With no interest rate change, investment should be unchanged, right? investment is determined by the interest rate, right? investment is determined by the interest rate.
01:30
The interest rate is not changed.
01:32
Oh, sorry.
01:33
The interest rate is going up.
01:34
Never mind...
