no macro economics Allah shmoop price ceilings and price floors
- 00:09
Yeah here's a price ceiling No more than a dollar
- 00:12
a square foot in rent And yes it's called rent
- 00:15
control And here's a price floor You can't sell arsenic
- 00:20
for less than 100 bucks a gallon because well probably

- 00:24
too many people would die if they drank it Yeah
- 00:26
it's a poison all right so yeah when the government
- 00:29
said some maximum price for something that's called a price
- 00:32
ceiling the rent control measures in New York City establish
- 00:35
a price ceiling for the rental rates of certain buildings
- 00:38
built in certain times With certain end it's The process
- 00:42
is rife with corruption like many wealthy people live in
- 00:47
these rent controlled buildings and take advantage of the system
- 00:50
But for our purposes just know that they set a
- 00:53
max rental rate and that's a price ceiling Like you
- 00:57
know you can rent it for more than whatever per
- 00:59
foot per month Yeah alright The intention behind setting a
- 01:03
price ceiling is arguably good One a certain good or
- 01:06
service has become so expensive that it's nearly impossible for
- 01:10
many normal people to afford So you know the government
- 01:15
wants to make it more affordable Well how many times
- 01:18
have we said to ourselves I wish this thing that
- 01:21
I need was cheaper fry ceilings or the government's way
- 01:24
of trying to make that wish come true But like
- 01:27
all things literary there's a price to pay for trying
- 01:30
to defy gravity Of course setting a price cap can
- 01:34
deliver unintended consequences if a price ceiling is set below
- 01:38
the equilibrium price for that good or service a shortage
- 01:42
of results Alright so what's an equilibrium point In economic
- 01:46
terms it's worth supply and demand meet Check out this
- 01:49
graph again it It shows how supply changes as prices
- 01:52
change That's the supply curve It's on very Kirby here
- 01:57
Just supply line If there's a lot of demand for
- 02:00
given product at a given price well if it makes
- 02:02
sense to produce more thin producers will produce more Yeah
- 02:07
duh Like who doesn't want to make money Now check
- 02:10
out this graph Well It shows how demand changes as
- 02:14
prices change That's the demand curve where the two curves
- 02:18
intersect While that's the equilibrium point right where if supply
- 02:21
equals demand it's where the market reaches a balance between
- 02:25
supply and demand And that is it's where the prices
- 02:28
are such that sellers and buyers are both equally happy
- 02:32
and unhappy with the price they're paying for a given
- 02:35
number of transactions You know kind of like Mama Thanksgiving
- 02:39
equally happy and unhappy But what happens if the government
- 02:44
mandates the setting of an artificial price That is they
- 02:48
don't let the market reach its equilibrium point You know
- 02:51
you got problems all right In the case of Rent
- 02:54
Control you've got a price below the equilibrium point Living
- 02:57
right down here somewhere you end up with too much
- 03:00
demand for too little supply Like who wouldn't want to
- 03:04
pay 400 bucks a month for this beautiful four bedroom
- 03:07
apartment overlooking Central Park Its market price is probably like
- 03:05
20 grand a month Another example Immediately after a snowstorm
- 03:16
people run to the store to get road salt and
- 03:19
if you live in California or Arizona or anywhere else
- 03:23
where changes in weather don't exist people put salt on
- 03:27
roads so the ice on the roads melts off because
- 03:31
you know science In order to make driving and walking
- 03:34
conditions safe the government caps the price of rock salt
- 03:38
so that everyone can afford it And this kind of
- 03:41
makes sense right Because it would be bad for a
- 03:43
whole lot of innocent streetwalkers are rather you know people
- 03:46
walking on the street to have a bunch of road
- 03:49
unsalted and icy and you know driver's running into them
- 03:54
You know it's not good in essence forcing rock salt
- 03:57
prices to be low The government is protecting a bunch
- 04:00
of innocent potential victims but there's a price to pay
- 04:03
for this protection The low prices mean people bum rush
- 04:07
stores and clear amount of supply The shortage of rock
- 04:11
salt comes about because stores simply can't meet consumers The
- 04:14
man All right well let's see what this looks like
- 04:17
on a graph Let's say we live in a city
- 04:19
where the equilibrium price for a one bedroom apartments 1200
- 04:22
bucks and the government institutes a price ceiling of a
- 04:24
grand Well the price cap messes with the market impacting
- 04:28
both supply and demand Demand has increased because well now
- 04:31
there are more people who can afford the apartment who
- 04:34
couldn't come up with the cash when it was $200
- 04:37
Mohr expensive That's the government school toe Let people afford
- 04:40
these nicer apartments who weatherize couldn't But the policy also
- 04:45
effects supply a government Price control obviously doesn't instantly destroy
- 04:51
a bunch of apartments but it changes the incentive structure
- 04:54
making it less profitable for the landlords and the shareholders
- 04:58
of the buildings To rent out those apartments well owners
- 05:02
will start looking for places to put their resource is
- 05:04
other places like not in improvements in the buildings They
- 05:08
may turn the apartments into condos They might sell the
- 05:12
whole building's altogether or try to turn the whole thing
- 05:15
into retail space over the long run Fewer new apartments
- 05:19
of this type will then be built because investors aren't
- 05:22
incentivized to do so The current price structure makes no
- 05:26
sense for him so well that's kind of bad Well
- 05:29
are the opposite of a price Ceiling is a price
- 05:32
floor which is a government imposed limits on how low
- 05:35
the price of a good or service can go Example
- 05:39
Well after the Great Depression the U S Government instituted
- 05:41
several price floors an agricultural markets in an effort to
- 05:45
protect farmers from the horrible economy Well this was all
- 05:48
part of the New Deal you know that thing Frankie
- 05:50
D came up with to give victims of the Depression
- 05:53
about a financial relief Okay so let's bring things forward
- 05:56
In the time of it pretend the government decided to
- 05:59
set a price for five bucks for the newest iPhone
- 06:02
That means no one could charge less than $5 for
- 06:05
the new iPhone Well since new iPhones clearly cost the
- 06:08
manufacturer and mostly apple more than five bucks well like
- 06:13
a a bunch more than five bucks we can say
- 06:15
with confidence that the equilibrium price for an iPhone is
- 06:18
higher than the price floor Well in this situation the
- 06:21
price for has pretty much no effect on well anything
- 06:24
right because Apple has no incentive to make any more
- 06:26
iPhones if they cost them say $200 each and the
- 06:30
government is telling them they must sell them for more
- 06:32
than $5 each So of course they will sell them
- 06:35
for more than $5 each Ida But let's say that
- 06:39
price floor was changed from $5 toe $500 Well now
- 06:45
no one Khun settle an iPhone for under 500 bucks
- 06:48
Well that changes things a bit doesn't it First of
- 06:50
all most of us are probably not going to run
- 06:52
right out and buy a new iPhone for $500 in
- 06:55
second Anyone who does pay 500 bucks for their phone
- 06:58
is now paying a price that is higher than the
- 07:00
equilibrium price Well Third given the dramatic drop in demand
- 07:04
Apple's going to end up with a major surplus of
- 07:07
iPhones If they don't do anything about supply like they'd
- 07:10
better cut back on building more iPhones Because now this
- 07:14
ultra expensive iPhone is going to have less volume demand
- 07:17
then would it If it's sold for say 300 bucks
- 07:20
All right let's look at this on a graph Assuming
- 07:22
the equilibrium price for an iPhone is a $250 Apple
- 07:26
is selling iPhones at an artificially high price That is
- 07:29
above the equilibrium point up here Will you Khun see
- 07:32
the place where the price floor hits the supply curve
- 07:35
You can also see where the price for hits the
- 07:37
demand curve Right here There's a big gap between the
- 07:41
two Well at 500 bucks Apple wants to make a
- 07:43
lot of iPhones but unfortunately for them not many people
- 07:47
want to buy a lot of iPhones at 500 bucks
- 07:50
in thank you very much All right There are benefits
- 07:52
and drawbacks to price controls They can protect consumers by
- 07:55
making sure they can afford what they need And they
- 07:58
can protect companies by making sure they won't go broke
- 08:01
producing their goods and services that they might not otherwise
- 08:04
make But they can also lead to economic disequilibrium where
- 08:07
supply and demand are artificially controlled and lead to shortages
- 08:11
and surpluses And over the long run you want to
- 08:13
kind of let the market do your boss right It's
- 08:16
kind of like finding an affordable apartment in the Windy
- 08:18
City Instituting price controls well it involves making some major 00:08:22.249 --> [endTime] trade offs
