Mr. Clifford: Hi, I'm Jacob Clifford and I'm
the host of Crash Course economics. Stan!
Adriene: Hi, I'm Adriene Hill and I'm the
host of Crash Course economics. Stan! Stan: You're a team! You're co-hosts. Adriene: All right, awesome.
Mr. Clifford: Yeah, whooo! Adriene: Well anyways, we're making our Crash
Course Economics series at the YouTube space in lovely Los Angeles California because Mr.
Clifford and I are both from Southern California. Mr. Clifford: Yeah. Statler: Who are these no-names!? Waldorf: Where are the Green brothers? If
there aren't any Greens, I'm unsubscribing. Statler: Wh– how can you unsubscribe? What
is this, some kind of a moving newspaper? Mr.
Clifford: Did we just get heckled by the
muppets? Adriene: It sounds like it. Kermit: Hey guys, hey guys listen, don't feel
bad about not being green, OK? Adriene: It's Kermit! Mr. Clifford: That's crazy! Kermit: Hi guys, uh listen, being green is
great and everything but being Adriene and Mr. Clifford well, that's great, too! In fact,
you know guys, it's not easy being green. I think I could sing a song about that. Adriene: Can I sing with you?
Kermit: Oh course, yeah.
Adriene: This is a dream. This is a dream. Mr. Clifford: No, no, no, we can't afford the licensing
agreement for that song guys, economics. Sorry. Kermit: Oh. Oh. Well, in that case, why don't
you guys just introduce yourselves? Mr.
Clifford: OK. I'm Mr. Clifford, and I'm
a high school economics teacher and YouTuber, and I'm going to focus on teaching you the theories
and graphs of economics. You know, the textbook stuff. Adriene: And I'm Adriene Hill; I'm a senior
reporter for the public radio show Marketplace, and I'm gonna focus on showing you the real
world applications of economics. You know, the good stuff. The really fun stuff. Mr. Clifford: Hey! We're both fun! We're definitely
not gonna teach economics like this: Prof. Bunsen Honeydew: Welcome to CrashCourse
Economics (Beaker yawns) I am thrilled to be teaching you this fascinating subject.
(Beaker moans) Mr. Clifford: I'm sorry Professor Honeydew, but that's
why people hate economics in high school and college. Adriene: Anyway, Statler and Waldorf have
a point, the most important question in economics is "Where's John Green?" I mean everyone knows
he won a bronze medal in economics at the Alabama State Academic Decathlon. Well, John Green
isn't hosting because economics. We'll explain later. [Theme Music] Mr. Clifford: So let's start with the basics.
What is economics? Well it might be easier to term it what economics isn't.
is not the study of money or getting rich, although understanding economics can help
with that. Economics is not the study of the stock market. It's just not. And economics
is not primarily about men in bow-ties forecasting what will happen in a given market or the
overall economy. Actually, a few economists do that, but that's not the main focus of
economics. Economics is the study of people and choices.
The famous economist Alfred Marsh defined economics as "A study of man (Adriene: And
woman!) in the ordinary business of life. It inquires how he gets his income and how
he uses it. Thus, it is on the one side the study of wealth and on the other and more
important side a study of man (Adriene: And woman)." Adriene: So let's talk a minute about what
else econ is.
Economics is an 18 year old deciding whether to work or go to college and
how that affects her future income. Economics is a company deciding whether to produce smartphones
or tablets and how that's influenced by what we consumers want to buy. Economics is the
government deciding whether to increase its spending when it's a recession and if it's
worth going into debt. So despite what you might think, economics
is not boring and dull. OK, some of it is, but it's not all like that I promise! It's
awesome. Understanding econ can forever change the way you think and problem-solve. Our job
over the next 40 weeks is to teach you concepts that will help you understand the world, and
hopefully make it a better place.
No matter who you are, you will be using economics.
In fact, pewww! You are using econ right now, you made a choice to watch this video, that
means you must feel that the benefit outweighs the cost. You might be thinking "This is YouTube,
there's no cost," but sure there is. You could be watching videos of kittens or skaters falling
on their face or charlie biting fingers. Ow! The cost of watching this video is the video you're
not watching, the value of the next best alternative. Economists call this your opportunity cost.
If you're still watching this video it means that you believe it's the best use of your
time, or you wouldn't be watching it. "But what if I'm watching this at school?" you
ask, "What if I'm forced to watch this?" Well, you weren't forced to go to school, you could
ditch, you could drop out, you could move to a country that doesn't have compulsory
But the cost would outweigh the benefit. Even if you are at school, you're
not forced to watch the video, you could close your eyes or put your head down. No one's
gonna pry your eyes open, that'd be creepy! Now let's talk about why John Green isn't
here teaching this course. John is an entrepreneur, he writes books, runs DFTBA, Vlogbrothers,
and Mental_Floss and creates movies, but he can't do everything he wants to do. He looked at the benefits
and costs of his choices, and in the end decided to spend more time writing books, so Mr. Clifford
and I are jumping in to teach you economics. Mr. Clifford: And believe it or not, we just
covered the two most important assumptions in all of economics. First, the idea of scarcity.
People have unlimited wants but limited resources, and second, everything and I mean everything
has a cost. And if these assumptions are true, then we need a way to analyze our choices
and get the most from our limited resources.
And that's economics. Adriene: Wait, but let's go back to the idea
of benefits and costs. About 30,000 people a year die in car accidents in the US. Is
there a way to ensure there will never be another traffic fatality? Yes! We can crush
all the cars, close all the roads, and force everyone to walk. That would solve the car
crash problem. Do you want to decrease the number of people convicted of murder? You
could decriminalize murder. You want to end the unethical treatment of elephants? You could
kill off all the elephants, in an ethical way of course. But before you decide to tenderly euthanize
herds of beautiful elephants, think about it for a second.
Each of these solutions is
absurd because the cost clearly outweighs the benefit. Traffic fatalities are tragic,
but we don't prevent them at all costs. You know that driving has risks, that you might
get in a car accident, but you still drive. Why? Well first, who's gonna walk to the gym?
And walking home with groceries in the rain is way worse than the teeny-tiny chance of
dying in a car crash. The point is, individuals, businesses, and countries can't have everything,
so they're forced to weigh the benefits and costs of their decisions and make choices. Let's look at another example. Military spending
in the United States is over 600 billion dollars per year, that's close to what the next top
ten countries spend combined. There are a total of about 20 active aircraft carriers
in the world, and the US has half of them, and it's building more.
The opportunity cost
of those aircraft carriers could be hospitals, schools, and roads. So, is the US spending
too much on the military? Should the US focus on making guns or butter? That is, weapons
or consumer goods? Mr. Clifford: And notice the key word here
is "or," we can't produce an infinite amount of weapons AND consumer goods because we don't
have an infinite amount of workers and farms and factories and raw materials. Scarcity
means we must make a choice. The American president Dwight D. Eisenhower explained this best
in 1953 in a speech about Cold War military buildup. "Every gun that is made, every warship launched,
every rocket fired signifies, in the final sense, a theft from those who hunger and are
not fed, those who are cold and are not clothed. This world in arms is not spending money alone.
It is spending the sweat of its laborers, the genius of its scientists, the hopes of
its children." And this is a good time to mention the role
of politics in economics; we're not pushing some liberal anti-military policy here.
just pointing out that military spending has an opportunity cost: The resources not being
used for social services like feeding the hungry. We're gonna try not to push a political agenda
on you. We're gonna show you both sides and let you decide which one's best. So please
don't say "Mr. Clifford loves capitalism, so he's just a pro-business conservative,"
or "Adriene's talking about environmental regulations, so she's an anti-business liberal." Yeah, we are pro-business and you are too.
I mean, where do you think your computer came from? That computer was brought to you by
capitalism and the private sector. But that being said, the security and laws, roads,
and that traffic ticket you got the other day came from the government.
Conservatives and liberals fight over the
details, but the free market alone can't solve all of our problems. And the government can't
solve all of them either. Government officials use economic theory to guide public policy;
their effects are widespread and affect millions of people. Sometimes a theory is flawed, but
many times a policy is flawed. Economists adjust theories supported by data and understanding
of incentives. Having the right incentive is key. Adriene: But the right incentives can be hard
to figure out. Take for example public colleges and universities. Many of them used to get
state money for each student they enrolled. That meant universities had financial incentives
to focus on recruiting as many students as possible, but not actually helping them succeed
once they were in class. So states have started changing the incentives.
Now, more and more states reward schools for the number of students that complete courses
or earn degrees.
And in some places this has worked; it's helped schools increase their graduation
rates by shifting money from marketing budgets to programs to help students do better, but those
incentives can also backfire if they're poorly designed. A university that gets money for graduates
could push students through the program without giving them a good education. It might want
to only admit students who come in with super high test scores, instead of considering other
factors that might make them good candidates. It might push students into less-rigorous
majors. But incentives can help solve problems without
adding more resources. You just have to get the incentives right. Many non-economists
assume that the way to improve things like healthcare is to spend more money. Economists would point out that the US already
spends almost twice as much per person as other rich countries, and in many cases they
get worse health outcomes. Economists would also say that rather than spending more money,
we need to make sure that insurers, doctors, hospitals, and patients have incentives to
produce the most effective care possible at the lowest cost possible.
The point is, if you
mess up the incentives, the policy's not gonna work. When Vietnam was under French colonial rule,
the regime issued a bounty on rats to exterminate them, giving money to people for handing in
rat tails. I guess because piles off rat bodies were too gross. The plan backfired. To make
as much money as possible, the rat-catchers cut the tails off the rats and released them,
allowing them to make baby rats.
The policy actually increased the rat population. It
made things worse. Eek! We'll talk more about this idea of perverse
incentives in another video, when we talk about the 2008 financial crisis. Eek again.
For now, let's go to the Thought Bubble. Mr. Clifford: Speaking of 2008, people sometimes
criticize economists asking "Why didn't they predict the 2008 financial crisis?" or, "why
can't they agree on what the government should do or shouldn't do when there's a recession?"
These criticisms fail to distinguish between macroeconomics and microeconomics. Specifically, all these complaints are about
macroeconomics. Macro studies the economy as a whole; it looks at the whole nation's
output, unemployment, interest rates, government spending, and growth. Macro answers questions
like "Will unemployment rise if there's an increase in taxes?" "Will and increase in
the money supply boost output or just increase inflation?" "Will a slump in European economies
cause the US economy to slow down?" Macroeconomists get more airtime because they
predict the direction of the overall economy, and work with the media and businesses and
congress and the Federal Reserve, but less than half of all economists are macro economists;
there's a whole other side of economics that look at different questions.
"How many workers
should we hire to maximize profit?" "If our main competitor releases their product in
May, when is the best time to release our product?" and "which is better for fighting
climate change, a gas tax, or increase in fuel efficiency?" These are all microeconomic
questions. They're not about predicting GDP, or measuring unemployment, but they are crucial
questions that economists must answer. Also, if you don't know what GDP is or what a high or low
unemployment rate is don't worry, we'll get there.
So macro and micro-economists are two different
groups asking different questions under one academic umbrella. If economics was biology,
macroeconomics would be ecology while microeconomics would be cell biology. If economics was physics,
macro would be cosmology and relativity while microeconomics would be Newtonian mechanics. Thanks Thought Bubble! Stan, I've always wanted
to say that. Now I can cross it off my bucket list. Now I have "ring the opening bell at
the New York Stock Exchange," "arm wrestle Ben Bernanke," and "swim in a giant pool of
money like Uncle Scrooge." Adriene: Obviously we're glossing over the
details, but we promise to cover everything in the next 40 weeks from supply and demand
to monetary policy, we'll cover it all. Except for maybe the giant pools of money. We can't
promise you that learning economics will make you wealthy, but we can promise that learning
economics will enlighten your mind and make you a more informed decision maker. And that
makes us all better off.
Thanks so much for joining us. We'll see you next week. Mr. Clifford: Thanks for watching Crash Course
Economics. It was made with the help of all of these nice people. They work on the show
because there's financial and implicit benefits that cover their opportunity costs. Now, if
