- 00:08
All right people while the invisible hand does a lot
- 00:11
of good bringing consumer demand to producer supply at equilibrium
- 00:16
But sometimes the invisible hand can't work its magic For
- 00:19
instance in cases of monopoly on Olonga pally firms are

incentivized to produce less quantity at higher prices you know
- 00:27
than they would if they had some competition Well in
- 00:30
cases like these the government can step in to try
- 00:33
to correct the market making it more efficient by setting
- 00:36
price and quantity controls In other cases the government may
- 00:39
set price and quantity controls in response to social issues
- 00:43
and actually creating market distortion rather than a correcting one
- 00:48
So how do price and quantity controls work If you
- 00:52
look at your typical supply and demand graph like this
- 00:54
take a look at the axes on the X axis
- 00:56
We've got quantity on the Y axis We've got price
- 00:59
Since the X axis and a Y axis are price
- 01:01
and quantity on the graph well those are the two
- 01:04
things the government has to play with to affect the
- 01:06
markets No excess demand or supply means we're at equilibrium
- 01:11
where supply and demand cross like right there This means
- 01:13
the supply a good or service is sold at matches
- 01:17
the same supply demand it all for an agreed upon
- 01:20
price by buyers and sellers What market inefficiencies produce what's
- 01:24
called a dead weight loss which we can see on
- 01:27
the graph right there representing the cost of inefficiency When
- 01:31
there's either excess supply or excess demand while we Khun
- 01:33
see dead weight loss the larger the deadweight loss triangle
- 01:37
on the graph while the farther away from equilibrium The
- 01:40
market is when there's excess demand That means there's a
- 01:43
shortage of supply when lots of people want a limited
- 01:46
quantity of stuff while prices skyrocket On the flip side
- 01:50
when there's excess supply demand shrinks When there's an abundance
- 01:53
of something compared to you know how much of it
- 01:56
people want Well prices fall sometimes Government price in quantity
- 02:00
controls are designed to reduce deadweight loss and other times
- 02:02
these controls create deadweight loss First up price controls A
- 02:07
government can set a price control basically setting price limitations
- 02:12
on firms in a certain market Well there's two main
- 02:15
types of price controls Price ceilings and price floors Well
- 02:18
price ceilings mean there's an upper limit on how much
- 02:21
affirm Khun Selig odor service for For instance a government
- 02:24
might set a price ceiling on something that everyone needs
- 02:27
to keep you know affordable like food for natural monopolies
- 02:30
that affect a lot of society like utilities Internet service
- 02:34
providers and buses that buses Will governments oftentimes set a
- 02:38
price ceiling Will these air all natural monopolies since their
- 02:42
monopolies that happened spontaneously from very high fixed startup costs
- 02:46
Price ceilings on natural monopolies like these insure businesses aren't
- 02:51
taking too much advantage of their monopoly status and overcharging
- 02:55
consumers on those evil business is rent controlled areas are
- 02:58
another example of price ceilings However rent controlled areas are
- 03:02
more likely creating a dead weight loss Ten Getting rid
- 03:05
of one but artificially lowering the cost of housing that
- 03:08
creates excess demand Rent control Lower supply to since that
- 03:14
means landlords and rent controlled areas will be feeling the
- 03:17
squeeze of the price ceiling Why be a landlord in
- 03:20
an area where prices are kept artificially low Hello rent
- 03:24
control when you could be a landlord in an unregulated
- 03:27
red state area with much higher rent prices in therefore
- 03:31
profits These landlords and rent controlled areas who are making
- 03:34
less money because of government intervention are then incentivized to
- 03:37
provide housing with you know worst quality Another reason government
- 03:41
might set a price ceiling is to prevent hyper inflation
- 03:45
which history has told us happens often during war time
- 03:48
Right Well price floors are the opposite you know when
- 03:51
a government sets a lower bound on price for firms
- 03:54
While price ceilings often help consumers price floors often help
- 03:58
producers For instance governments sometimes help farmers out by setting
- 04:03
price floors on things like milk By setting the price
- 04:06
artificially high though this can create reduced a man and
- 04:10
excess supply usually does well In the case of farmers
- 04:12
governments usually set price floors along with the promise of
- 04:16
buying up any excess supply from farmers Well why does
- 04:19
the government bother helping out these farmers and keeping him
- 04:21
around Technology made farming go from meeting a ton of
- 04:25
people needing very few people for the same output of
- 04:28
food producing on mass farming equipment fancy fertilizers and pesticides
- 04:32
Ball radically transformed the farming industry Some governments have used
- 04:35
price floor simply to reduce consumer demand for a good
- 04:39
for instance making alcohol or tobacco more expensive would ideally
- 04:43
drive demand for alcohol and tobacco down well in the
- 04:46
labor market Minimum wages a price floor Here the suppliers
- 04:49
are workers not the firms Firms are demanding labor and
- 04:53
workers are supplying it to remember when the price of
- 04:56
something rises It's usually followed by a drop in demand
- 05:00
Okay so what about quantity controls Well a quantity control
- 05:04
is usually referred to as a quota and it limits
- 05:07
the quantity of a good quotas work well in cases
- 05:10
when controlling the quantity is easier or more important than
- 05:14
controlling the cost For instance a government may set a
- 05:17
quota for nuclear power plants since there's a potentially high
- 05:20
social cost If you know something went awry and the
- 05:24
international markets it's common for countries to set import quotas
- 05:28
So this quota restricts a supply of a certain good
- 05:30
from international markets so that gives the domestic country a
- 05:34
leg up against them Foreign competitors like another example of
- 05:37
quota on imported steel would mean that domestic steel firms
- 05:41
would get an advantage over imported steel while international quotas
- 05:45
benefits some domestic firms This comes at the cost of
- 05:48
everyone buying the goods meaning a steel quota in the
- 05:51
US would mean higher steel prices from domestic steel producers
- 05:54
then from cheaper foreign producers in an unregulated market A
- 05:58
limited number of hunting and fishing licenses and tags are
- 06:01
another example of quotas in order to keep hunting and
- 06:04
fishing populations you know in existence the young ones have
- 06:07
to be given time to be born grow up and
- 06:09
reproduce right Well oftentimes A combination of quotas and price
- 06:13
floors in the form of high price licenses and tags
- 06:16
are used to keep hunted and fished populations at sustainable
- 06:19
levels Setting a quota a quantity limit has similar effects
- 06:23
as a price floor Artificially restricting quantity sold means higher
- 06:26
prices and lower demand compared to free market equilibrium Well
- 06:30
if you were wondering it's not too common when a
- 06:33
capitalistic government sets a quantity minimum or floor But if
- 06:36
they did in theory it'd create a surplus of supply
- 06:38
compared to equilibrium levels and potentially would need to be
- 06:41
supported by the government like price floors on agriculture to
- 06:45
make up for the lack of demand Well for instance
- 06:47
let's say in the future the government created an enforceable
- 06:49
law on the labor market making firms hire a minimum
- 06:52
number of people in response to shrinking jobs Yes Hello
- 06:56
Robots They're coming for our jobs Firms would then be
- 06:58
forced to hire people when they wouldn't want or need
- 07:01
thio creating forced oversupply of workers on two firms Well
- 07:06
all this government regulation can breathe rebellion rebellion in the
- 07:09
form of the underground economy the market free of any
- 07:12
government regulations And yes black market milk is a thing 00:07:15.992 --> [endTime] just like black market booze Hey
