Let's use this diagram of the business cycle to answer the following questions about how fiscal policy changes automatically when output and employment fluctuate.
00:09
So the first question is explain why tax revenue changes when the economy goes into a recession.
00:16
So first let's look at just this basic graph we have over here.
00:20
So we have gdp on the y -axis and time on the x.
00:23
So this vertical line or sorry, this linear line right here represents potential gdp as a we increase in time, right? but this represents the business cycle.
00:34
So these are times of economic growth.
00:37
Here i'll draw a blue dot up here.
00:39
So this is economic growth.
00:41
And then this red dot down here would be when actual gdp is below potential.
00:46
So this is our recession down here.
00:48
All right.
00:49
So when we have a recession, we have gdp lower than usual, right? so actual gdp is less than potential.
01:02
Right.
01:02
So what this means is that, so employment, employment is going to be less than potential as well, right? because if we're not making as much product as we could, that means we're not employing as many people as we could to make that extra product that we're lacking.
01:19
Right.
01:19
So if employment is less than potential, that means, and we have steady income tax rate, right? that means that, so less, more people have less income, right? so if we have less income overall, let's say, we have less income overall, let's say, we have.
01:32
Income overall.
01:33
That means we'll have less income tax.
01:36
Income tax revenue...
