So here we're talking about price controls and we have a market and i'm going to replicate that market.
00:05
I'll even match the colors, right? demand curve slopes down, supply curve slopes up.
00:11
In the absence of price controls, we would have a free market equilibrium at 20 and 24, right? but the government is interested in the price being 25.
00:22
So in the first case a, the price is equal to a of 25, right? and so the price would like to be lower, but it can't actually be lower, right? so the market gets hung up right here.
00:36
The price would like to fall down to the 20 equilibrium, but it can't.
00:41
So if you look at this 25 price, you have to squint a little bit on the diagram, but it looks like the quantity is 12 and it looks like this point here is 15.
00:51
And we need that because the deadweight loss is going to be this triangle here, right? the deadweight loss is the difference between demand and supply over the units that don't get produced, right? so the deadweight loss here is a triangle and the formula for the area of the triangle is a half a base times a height.
01:10
The base of the triangle is 12...
