Adriene: Welcome to Crash Course Economics.
My name is Adriene Hill
Jacob: And I’m Jacob Clifford, and today
we’re going to talk about good intentions,
and how they can go wrong. Price controls
can derail markets. And subsidies can distort them.
Adriene: And “deadweight” isn’t just
a good description of your ex.
[Theme Music]
Jacob: Let’s say Craig becomes president
and he caps the prices of all consumer goods.
He argues that the lower price will help everyone
-- the poor, the middle class, small businesses,
everyone. Maybe a few people might fall for
this policy, but not you.
You watch Crash Course Economics, which means
you're funny and smart and attractive, and
you understand why this is a horrible idea.
This example seems far fetched, but it actually
happened...not the part of Craig being president.
Instead it was President Richard Nixon.
In the early 1970s, Nixon established a 90
day price and wage freeze designed to fight
inflation. The general public supported the
idea, but economists were skeptical. In fact,
Milton Friedman called the freeze “one of
those ‘very plausible schemes…with very
pleasing commencements, [that] have often
shameful and lamentable conclusions’.”
Economists call this idea of the government
setting prices, price controls. Now, there's
two types and we're gonna look at both of
them in the Thought Bubble.
Adriene: When the government sets a maximum
price for a specific good or service, that’s
a price ceiling. Let's say the government
forced gas stations to charge a dollar per
gallon for gas. This might seem like a good
idea, right? Mandated lower gas prices mean
we all benefit. Not really. Society is actually
made worse off. When the gas prices fall consumers
will want to buy more, but producers will
no longer find it profitable to sell gas.
The lower price will decrease the amount of
gasoline produced, and we've got a shortage.
A price floor is a law that sets a minimum
price in a specific market. The idea is to
help by keeping the price artificially high
and not allowing the price to fall down to
equilibrium. Let’s make up an example using
corn. Assume the government set a price floor
for a bushel of corn at $7 when the actual
equilibrium price is $4. The higher price
would give farmers an incentive to produce
more, but, at that high price, consumers would
go buy substitutes -- things like wheat or
rice. Instead of cornflakes they'd buy rice
krispies. The point is, the farmers wouldn’t
necessarily be better off. They could sell
corn at the higher price, but they wouldn’t
have as many customers.
In terms of actually helping consumers and
producers, the vast majority of economists
consider price controls counter-productive.
But there is one notable exception: minimum
wage. The minimum wage is a really complex
issue that we’re going to address in a future video.
Jacob: Thanks Thought Bubble. Let’s look
at both these policies again using the supply
and demand graph. Assume the equilibrium price
for gas is $3 and the government sets a price
ceiling here, at only $1. At that low price,
consumers would want to buy more, so the quantity
demanded is gonna be here. The producers have
less incentive to produce gas so they're going
to make less, so the quantity supplied is
right here. The end result is that the quantity
bought and sold is going to fall resulting
in a shortage. The amount of gas society wants
is where supply meets demand. Producing any
quantity less than that will result in something
that economists call deadweight loss. So the
quantity produced at the price ceiling is
not allocatively efficient. We're not producing
enough. The lower the price ceiling, the more
the deadweight loss and inefficiency. Keep
in mind that the price ceiling only has an
effect on the market when it's below the equilibrium
price.
Adriene: Many countries still use price ceilings:
take Venezuela. In recent years they have
been experiencing high inflation, so the government
decided to impose price controls on consumer
products like basic foods, medicine, and toilet
paper. But, the new price is so low relative
to the cost of production that farmers and
factories can't make money. As a result,
they've reduced or halted production of many goods,
causing long lines, shortages, and empty shelves.
Rent control is another type of price ceiling.
Many cities, including New York and San Francisco,
put a cap on monthly rent for some apartments.
Again, the idea is to increase affordability
for tenants, which enables long-term tenants
to stay in their homes when real estate prices
rise. Meanwhile, the lower rent discourages
renovation and new construction, reducing
the quantity supplied. The result is a shortage
of apartments with landlords that have few
incentives to maintain their buildings or
be responsive to their tenant’s needs.
Economists are not at all split on rent control.
Pretty much all of them think that price ceilings
on rent reduce the quantity and quality of
the housing that's available.
Jacob: Now, how about a price floor? Well,
look at corn with an equilibrium price of
$4 per bushel and a price floor at $7. The
higher price will give farmers an incentive
to increase the quantity supplied. But, consumers
don’t want to pay those higher prices so
the quantity demanded's gonna fall. The result is
a surplus and deadweight loss, so society's worse off.
Now one argument for a price floor on corn
is that if farmers can’t get a high enough
price, they'll stop producing. Then we will
run out of food and die. Economists (except
for Malthus) are not fans of starvation so
they recognize that the government needs to
get involved sometimes to preserve our food
supply. But they don't use price floors.
Let’s talk about agricultural subsidies.
Adriene: A subsidy is a government payment
given to individuals or businesses. And they're
often designed to offset costs to advance
a specific public goal.
Let's say the government subsidizes farmers
that produce strawberries. This encourages
them to increase supply and the result is
more strawberries and a lower price. At first
glance, this sounds like a great idea. Prices
for consumers fall, farmers get more money,
and the market remains at equilibrium. There
is no shortage or surplus. Proponents of farm
subsidies say they can help provide a stable
living to farmers, limit food price inflation,
and make sure we grow enough food to feed
everyone.
But before you go out and become a lobbyist
for farm subsidies, keep in mind that economists
don't like them. For one, many farmers these
days are not poor. By some estimates they
make more than non-farm families. Farmers,
economists argue, have the income they need
to handle price shocks. Economists also think
that subsidies might discourage farmers from
innovating and rethinking how they farm because
they have guaranteed income from the government.
A survey of economists found that 85% think the
United States should eliminate agricultural subsidies.
But what do economists have against farmers?
Jacob: Economists don’t have it in for anybody.
Except maybe physicists, because they have
unbreakable laws and perfectly controlled
experiments. Man I wish economics was a science!
Economists recognize that market prices are
set for a reason. If corn prices are down
because demand has fallen, then it's inefficient
and wasteful to spend money on subsidies.
That said, if there is a drought or other
natural disaster affecting farmers then some
sort of short-term aid might be needed to
keep farmers on their feet. But today, farm
subsidies in the US were not about giving a little money
to help ma and pa make it through a tough season.
Adriene: In the US, agricultural subsidies
have been around since the Great Depression.
They were meant to help prop up farm prices
and farmers. The Agricultural Adjustment Act
of 1933 paid farmers not to grow crops on
some of their land. The government also bought
up excess crops. For decades after, farmers
of crops like corn, wheat, cotton, and soybeans
received government help. In the late 1990s
Congress added new farm programs, including
what are called direct payments. Basically,
the government handed out checks to farmers
based on land ownership and historical production
levels. Farmers got them regardless of the
market price for crops or how much they produced.
According to The Washington Post, “In 2005
alone, when pretax farm profits were at a
near-record $72 billion, the federal government
handed out more than $25 billion in aid…”
That was almost 50% more than it paid to families
on welfare. The Washington Post also found
the government gave over 1.3 billion dollars
to people that didn't farm at all.
In 2014, the government eliminated this system
of direct payment subsidies. Farm subsidies
still cost the government $20 billion dollars
a year, but a large portion goes to helping
farmers pay for crop insurance.
But economists don't like this much either.
Some argue that any form of government assistance
distorts the market, resulting in unintended
consequences. For one, it guarantees farmers
an income, and perhaps encourages them to
take more risks, like planting on less fertile land.
Jacob: So is it ever appropriate for the government
to give a subsidy? Well, let’s look at the
supply and demand graph again. A market's
going to produce the equilibrium quantity
and, in most cases, that is exactly the amount
society wants. But what if the amount society
actually wants is much greater? What if there
is something special about this product that
buyers and sellers aren’t factoring in?
In this case, the amount being produced is
less than the amount society wants. The result
would be deadweight loss. The inefficiency caused
by the underproduction of this product. A subsidy
would make society better off and improve efficiency.
Adriene: Let’s look at renewable energy technology.
Some economists like government subsidies
for research and development in energy. They argue
that things like solar panels would be underdeveloped
and underproduced without government action
and that subsidies reduce deadweight loss.
Other economists point out that businesses
already have an incentive to innovate, and
that subsidies create false demand. In essence,
they argue that there is no deadweight loss,
and even if there is, markets will adjust.
The takeaway from this debate is that subsidies
aren't inherently good or bad, it just depends
on the values of society and markets in question.
Just think, because of NASA, we have things like
scratch-resistant lenses, memory foam, Moonbase Alpha.
Jacob: So we stand by our claim, markets work.
They help us to determine the quantity we
should produce and help us to use our resources
efficiently. Now, government policies like
price ceilings and floors often fail to make
all of us better off.
Adriene: Sometimes, markets fail. And that's
when the government needs to step in.
