So here we're given a very interesting looking aggregate demand, aggregate supply model, right? that's a story about output and prices.
00:09
And we're given an aggregate supply curve that looks like this, right? something very squarish.
00:16
Then our aggregate demand curve looks something like this.
00:19
So the shock that we're considering here is a monetary shock, right? we're going to have tighter money.
00:29
And remember that tighter money affects the ad curve, right? the ad curve is c plus i plus g plus nx, and that's what money supply is targeting, right? egret supply is firm prices.
00:45
Money is not directly targeting that.
00:46
It's money is targeting demand, right? so ad is going to go in, and if i sketch that, we can easily see what's going to happen, right? the new equilibrium was here and the old equilibrium was here.
01:03
So we have a pretty small change in prices, right? only a tiny change in prices relative to a pretty big change in output, right? this is my change in output going this way.
01:19
This is my change in prices...
