So here we have a very topical discussion about carbon tax.
00:03
Again, just to lay out some ground rules, the carbon tax revenue that each person will have to pay will be proportional to some tax rate t times the number of units of carbon they are responsible for, whether those are from driving, from traveling via plane, from heating a house, etc., etc.
00:25
Etc.
00:26
But in general, we think that most things we do involve carbon, right? our transportation, our food, our housing, that's a lot of what we spend our money on.
00:35
So we can imagine that the carbon tax should be roughly proportional to our consumption expenditure, right? if most things involve carbon, then our total consumption spending is going to be a rough proxy for how much of our spending is subject to the carbon tax, right? so if you're rich, right, tc will be large.
01:06
So more will be paid, right? absolutely.
01:10
Rich people are going to be on the hook for larger dollars of the carbon tax.
01:17
They consume a lot more, right? rich people have larger budgets.
01:20
They consume a lot more.
01:22
Their total carbon tax payouts will be much larger.
01:26
The key counter example here, right, is that if poor, t over our carbon tax payments relative to our income will be smaller, right? this is carbon tax as percent of income.
01:48
And this is because poor people tend to spend a much larger fraction of their income on consumption, right? if i'm poor, i do not have the opportunity to save a lot of money, right? poor people tend to have very low savings rates...
