So here we are talking about aggregate demand.
00:05
I'm going to be drawing a number of these graphs.
00:09
We are always working between output and prices.
00:15
We have long run aggregate supply, short run aggregate supply, and aggregate demand.
00:22
So in a, we have expansionary demand, right? so in response to expansionary, expansionary means more y, right? so aggregate demand is shifting in the direction of more y, right? and that is going to yield a new short -run equilibrium right there.
00:47
Now in b, we have a supply shock that's leading to stagflation, right? so if i redraw this, output, prices, long run aggregate supply, short run aggregate supply, and aggregate demand.
01:09
So here we want b, stagflation, and of course the question says via supply.
01:17
Now what does stagflation mean? stagflation means high price and low y, right? as if we're in a recession.
01:25
So we are going up this way, right? to a higher price and to a lower level of output...
