That’s not correct

If a consumer is permanently removed from demand after ANY consumption, it changes your assumptions about the curve

You’re imagining a scenario in which there is indefinite demand in the long term

But if someone receives a vaccine tomorrow, they’re no longer generating demand, forever

You can’t compare it to other drugs, you can’t compare it to food, you can’t compare it to laser guns

You have to live in reality sometimes

Normally you’d talk about this as extremely inelastic demand

BUT

Because someone is REMOVED FROM THE DEMAND CURVE when they consume

The demand curve jumps to the left every time there’s consumption

So what actually happens is that without price controls, you’re only fulfilling part of the NEED even if you’re fulfilling equilibrium demand

But with price controls, you fulfill 100% of need

I don’t know how to say this without sounding condescending, so I’ll just say it

Sincerely; if you don’t understand, please go ask an economics professor

You’re still in school right? Just go ask one about the demand curve of vaccines

Of truly single use consumption goods

With low variable cost

Particularly when they have high front-loaded fixed costs

You can think of it as the inverse of a monopolistic pricing model actually- production will go till supply equals demand, non marginal

But that’s just a quirk

It doesn’t matter if it’s a “one time good”. It’s consumed over years, not at once. So demand curve is not effectively shifting but it is on equilibrium. This means a price cap will still cause shortages.

The equilibrium price is where shortages doesn’t occur, that means need is filled

@Sophie this is introductionary economics...

Except that it’s consumed at once, not over years.

Obviously yes it matters if it’s a one time use good.

Yes it’s introductory economics. If you had gotten further in economics the actual nuances of s/d would be explained to you

Sincerely, ask a professor.

I know you haven’t finished your degree

Everyone doesn’t buy the vaccine in one day. It’s over years and by different individuals and institutions.

First of all, no.

We’re talking about weeks, not years

Secondly, it doesn’t matter.

Standard s/d curves assume a RATE of market consumption

Here we have the rate changing as people drop out of demand after consumption

Vaccines won’t be finished in weeks, it’s buying time is over years

Like, just ground yourself in reality for a second

Right, the vaccine will be finished in about 18 months

Then the buying time is weeks

No, it isn’t bought out in weeks

Just like polio

It takes years
