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.
