  • Adriene: Hi I'm Adriene Hill.

  • 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

  • that really like them. Wink, wink.

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

  • that even mean?

  • 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?"

  • Mr. Clifford: No. No.

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

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

  • [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

  • like education and healthcare.

  • 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,

  • and who gets 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,

  • commerce, and trade.

  • 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

  • it.

  • 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

  • efficiently?

  • 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

  • do, because free markets won't.

  • 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

  • do they get the money? The households earn the money by selling the resources, like labor,

  • to businesses. Now, this is done in the resource market. The businesses use the money they

  • earn from selling products in the product market to pay for resources in the resource

  • market, and households use the money they earn in the resource market to buy products

  • in the product market.

  • But there's another key player in the economy: the government. The government also buys products

  • and resources. For example, they'll buy cars from businesses and hire government employees

  • like policemen to drive them. The government pays for public goods like roads and bridges

  • and public services like firefighters and teachers. They also provide transfer payments

  • to individuals in poverty and subsidies to businesses to produce things like fuel efficient

  • cars. But where does the government get the money?

  • Well, they get some of it from taxing households and businesses and they get some of it from

  • borrowing, but we'll talk about that later. So basically, that's it. That's the circular

  • flow of products, resources, and money, and the interactions between businesses, individuals,

  • and the government. Now, it gets more complex when you add in international trade and the

  • financial sector, but now, the simplified circular flow shows how the modern economy

  • works.

  • Adriene: Thanks, Thought Bubble. We've established that economies differ based on the amount

  • of government involvement, but it's important to keep in mind that economies can change.

  • Over time, Denmark and Canada have adopted more elements of a planned economy, like universal

  • healthcare. China, on the other hand, has added more free market elements to its economy

  • and now has less government ownership and control of production, so communist China

  • actually has a socialist market economy. But which type of economy is better and how much

  • should the government get involved?

  • It's hard to find support for command economies outside North Korea, and may some nostalgic

  • Cubans and Russians. Those who support socialism would point out Denmark's high standards of

  • living and low income inequality, but free market enthusiasts might point out China's

  • massive economic growth and growing middle class after backing away from central planning.

  • Ultimately, the optimal amount of government involvement depends on your personal values.

  • For example, what, if anything, do you think the government should do to help people in

  • poverty? Do you think it's up to each individual to provide for themselves, come what may,

  • or do you think the government should step in as a safety net and help pay for food and

  • healthcare? What if the person made choices that got them in financial trouble, like gambling

  • or made them sick, like smoking? Should society help then? Well, economists aren't really

  • good at answering these types of questions. Sorry.

  • It's not that they're heartless. It's just they don't operate in the realm of feelings.

  • In the words of economist Thomas Sowell, "There are no solutions, only trade-offs." Sure,

  • it would be great if we could end poverty or provide healthcare for everyone, but we're

  • gonna have to give something up in order to do it. Forcing car producers to meet emissions

  • and safety regulations will increase production costs and likely increase the price of cars,

  • but it also reduces pollution and fossil fuel consumption, which will hopefully improve

  • public health and save money in the long run. There is always an opportunity cost, and deciding

  • if it's worth it--well, that's up to you and your elected officials and a bunch of lobbyists.

  • Deng Xiaoping transformed China from a country with debilitating poverty and famine to the

  • economic powerhouse it is today. Regarding this debate, he said, "It doesn't matter whether

  • a cat is black or white, if it catches mice, it's a good cat." Which makes me think about

  • that green shirt, that was a good shirt. I'll be right back.

  • Mr. Clifford: So let's wrap this thing up. In practice, almost all countries are somewhere

  • between the extremes of a command economy and a completely free market economy. That's

  • because mixed economies seem best at handling the circular flow of goods, money, and resources.

  • But the debate over free markets and government control will never end.

  • Adriene: Well, actually, it will end, when humanity ends, because microscopic organisms

  • don't divide themselves into factions based on economic theory, but anyway, that's why

  • it's vital for you to be informed about the merits and the limits of economic systems

  • and be willing to support solutions that get the job done, as opposed to getting stuck

  • in one ideology. Economic theories and models can seem really great in the abstract, but

  • when they're kicked out into the real world and actually have to govern the affairs of

  • billions of people, it turns out that some flexibility is a very important thing.

  • Mr. Clifford: Thanks for watching; we'll see you next week.
