So the phillips curve is a relationship between output or or sorry, output or unemployment and inflation, right? so normally you would probably draw in output inflation space and you would look something like this.
00:24
And the inflation augmented one says that there's this point of equilibrium, right, this long -term equilibrium point is going to be at two things.
00:35
One, it'll be a potential output.
00:38
And two, it'll be at expected inflation, right? so equilibrium requires that inflation is equal to expected inflation and that output is equal to potential output, right? the economy here is balanced.
00:55
If output is low, that is unemployment is high, right? you get changes in the economy, right? the low output where the recession is going to affect.
01:08
So when inflation is at expected value and unemployment is at its natural rate or equivalently output is at potential, that's your long -term equilibrium, right? so this is a.
01:21
That is the correct answer.
01:23
But let me try to explain why the rest are wrong.
01:30
So b is wrong.
01:32
Because imagine that we're below inflation, right? if expected inflation is below inflation, right? that is inflation is greater than expected inflation.
01:44
That means you would be at something like point one...
