So here we're talking public finance and we have information about year, government spending, which i'll call g, tax revenues, which i'll call t, and gdp, which i'll call y, right? and we are thinking about a whole bunch of information.
00:18
So here's one, two, three, four, five, six.
00:22
We have 450, 500, 600, 640, 680, 600.
00:34
We have 425, 450, 500, 620, 580, and 620.
00:47
And we have, i'm just going to put it in thousands, 3, 4, 5, 4 .8, and 5.
00:54
So now i want to calculate two columns, right? the first thing is the deficit.
00:59
And the deficit is the difference between taxes and government spending, right? or the surplus in some cases.
01:06
So here, right, if i subtract these, or i guess i should say the deficit is, sorry, g minus t.
01:20
If i subtract these, you see that the government is running a deficit of 25.
01:25
And here it's running a deficit of 50.
01:27
And here it's running a deficit of 100.
01:28
And here 20, and here 100, and here minus 20.
01:33
So we can now calculate the debt.
01:37
And the debt, we assume starts at zero, because the nation came into existence at the beginning of year one.
01:44
So here the debt is 25.
01:46
Now we add 50 to our debt.
01:48
So it goes to 75.
01:49
Now our debt goes to 175.
01:52
Now it goes to, sorry, 195...
