Mr. Clifford: And I'm Mr. Clifford and welcome to Crash Course Economics.

Adriene: Today we're going to focus on macroeconomics and talk about economic systems and the nations

Mr. Clifford: "Economic systems and the nations that really like them. Wink, wink." What does

Adriene: I'm trying to come up with a spicy title for today's show. OK, try this one on.

how about "economic systems and the nations that are 'attracted' to them?"

Adriene: Or when economic systems and nations "hook up."

Mr. Clifford: I don't even know what to say. Stan, roll the intro.

Adriene: So to pick up where we left off, we all have wants. Food, cell phones, a good

education, a $10,000 gold Apple watch, but like the Rolling Stones tell us, you can't

always get what you want. We don't have an infinite amount of resources like raw materials,

workers, and time, so we have to make choices. Speaking of, eugh, who likes this? I'm gonna

go change shirts. I'm gonna make another choice.

So this shirt, it's way better, right? Anyway, we as a social order have to figure out three

things. Number one: what to produce, number two: how to produce it, and number three:

who gets it. Answer these three questions and you've got an economic system!

There's a ton of backstory here about the history and evolution of economic thought;

we'll get to that in a future video. In today's video, we're gonna chat about the world today.

Let's take a look at two different economic systems: market economies and planned economies.

Mr. Clifford: It all comes down to who owns and controls the factors of production. These

are the major inputs required to produce stuff and Karl Marx classified them as land, labor,

and capital. He even wrote a book about it, Das Kapital.

In a planned economy, the government controls the factors of production, and it's easy to

assume that's the same thing as communism or socialism but that's not quite right. According

to Karl Marx, "The theory of communism may be summed up in the single sentence: abolition

of private property." So true Communism is a classless society.

When I say classless, I'm talking about a social order where everyone owns the factors

of production, and output is distributed equally. Kind of like China, and Cuba and the former

Soviet Union, except not at all. In practice, no country has ever been truly communist.

There's a lot of countries that are socialist.

Often, socialism has both private property and some public ownership and control of industry.

The goal is to meet specific collective objectives and to provide free and easy access to things

In both communism and socialism, there is economic planning, and the government, usually

in the form of some bureaucratic agency, helps decide what to produce, how to produce it,

Now if an economy is completely controlled by the government, down to the number of shoes

that should be produced, that's called a command economy.

Adriene: On the other side of the spectrum, we have free market economies. In free market

or capitalist economies, individuals own the factors of production, and the government

keeps its nose out of the stuff and adopts a laissez faire or hands-off approach to production,

In free market economies, businesses make things like cars, not to do good for mankind

but because they want to make a profit. Since consumers, that's me and you, get to choose

which car we want, car producers need to make a car with the right features at the right

price. Economists call this the invisible hand. Oooooohhhh.

If consumers prefer one company's car, that business will make more profit and have an

incentive to produce more cars. Car companies that don't offer the cars people want will

disappear. Maybe you've heard of the DeLorean? It was a cool looking car, but not a car that

many people wanted to buy. Apparently it was expensive, underpowered, and poorly-made.

And it didn't actually travel through time.

Anyway, this concept applies to all other markets, like cell phones or shoes. Scarce

resources will go to the most desired use, and they'll be used efficiently, more or less.

After all, if a business is wasteful and inefficient or makes something that no one wants to buy,

then some other business will make a similar product that's either better or cheaper or

both. If there's no consumer demand for a product, resources won't be wasted producing

We often take markets for granted, but look at the alternative. Assume instead that a

government agency was in charge of deciding exactly which types of cars and cell phones

and shoes to make. Do you think they could quickly respond to changes in tastes and preferences?

If there was only one government monopoly producing cars, do you think they'd be produced

Mr. Clifford: So the invisible hand of the free market is the idea that individuals and

businesses meet society's needs when they seek their own self-interest. Competitive

markets with profit-seeking businesses will have an incentive to produce high-quality

products as efficiently as possible. In the words of Adam Smith, "It's not from the benevolence

of the butcher, the brewer, or the baker that we expect our dinner, but from their regard

to their own interest." Now, it looks like the free market's perfect and we don't even

need a government, but that's not quite right. There's a bunch of things the government must

First, is maintain the rule of law. We need laws and police and contracts and courts to

keep everything orderly. Second, we need public goods and services, like roads and bridges

and education and defense, because goods can't get to consumers if bridges are falling down,

and consumers can't make good choices if they're not educated, and no one really cares about

buying the new iPhone if there's a bomb dropping on your head. Third, the government sometimes

needs to step in when markets get things wrong, but what does that even mean?

Adriene: Well, let's go back to producing cars. The free market produces what we consumers

want to buy, and when we buy, we're thinking about what a car looks like. If it's the color

we want, maybe if it's safe, what it costs. Most of us aren't worried about air pollution.

We don't think much about who made our car, what they were paid, what the conditions at

the factory were like; that's when government steps in to regulate production. In a free

market economy like the United States, you might think that the government doesn't tell

car producers what types of cars to produce and how to produce them, except that it does.

Cars need to meet strict emissions and safety standards, and there are laws dictating how

much manufacturers can pollute and how workers should be treated, and here's the big takeaway:

modern economies are neither completely free market nor planned. There's a spectrum of

government involvement. For example, on one end we have North Korea. They have a command

economy where production is entirely controlled by the government. On the other end, we have

countries like New Zealand; they have private property, few taxes, and few regulations.

In the middle, we have the rest of the world. So most modern economies are actually mixed

economies with both free markets and government intervention.

Mr. Clifford: And a great way to explain a mixed economy is by looking at something called

"the circular flow model." Let's go to the Thought Bubble. A modern economy is made up

of households, which are individuals like you and me, and businesses. Businesses sell

goods and services to households in the product market -- that's anywhere goods and services

are bought and sold. The households need to pay for those goods and services, but where
