So in economics, taxes on things like alcohol and cigarettes are referred to as sin taxes, and they are often used to raise revenue.
00:06
And we have to talk about the elasticity of demand.
00:10
So here i've drawn a very elastic demand, and here i've drawn a very, going to draw a very inelastic demand, right? capturing different types of consumers.
00:24
If you have an elastic demand, it means that people will respond a lot relative to the price.
00:29
And an inelastic demand means that they won't.
00:32
They'll just suck up the higher price and stick with the same quantity.
00:36
So now we're going to impose a tax.
00:38
The tax increases the supply curve, reflecting the increased cost.
00:44
And you can see in the demand, when it is quite elastic, we get a big change in q, right? because the tax generates a big behavioral shift.
00:56
But the big change in q means less revenue.
01:02
Because when the demand is elastic, it means that we don't get as many units sold.
01:09
And so the revenue is maybe not as big as the state would like...
