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

Adriene: So far we talked about GDP and how the overall economy, but we haven't really

talked about why some countries have a high GDP and others have low GDP. So, why are some

Mr. Clifford: Look, a clue! Productivity!

Mr. Clifford: So, if we're gonna figure out why some countries are rich and some are poor,

we have to first define what it means to be rich.

Economists measure economic output by looking at Gross Domestic Product or GDP. As you remember

from the last video, GDP is the market value of all goods and services newly produced in

India's GDP is over six times larger than the GDP of Singapore, but that doesn't mean

the average Indian is richer than the average Singaporean. That's because India has 240

So, economists look at something called GDP per capita, to determine how wealthy a country

is. GDP per capita is the GDP of the country divided by its population. It represents output

per person, and a country with a high GDP per capita is considered rich.

Of course, some of you may say being rich has nothing to do with GDP or money. It has

to do with whether or not you're happy. Fine, money may not buy happiness, but it can prevent

a lot of misery. The United Nations' Human Development Index, or HDI, measures life expectancy,

literacy, education, quality of life, and it ranks countries according to their findings.

The data shows the country that have a high GDP per capita have far less infant mortality,

So, economists often used GDP per capita to measure a country's standard of living. Countries

with the lowest standard of living are the ones that are conventionally considered poor.

Adriene: If you ask someone on the street, they might say the difference is due to lack

of natural resources or inept governments, that is if the person doesn't subscribe to

some antiquated racial or social Darwinist stereotypes -- but we should talk about those

ideas. Well, let's skip the racial and social Darwinists stereotypes, but resources and

First, resources. Look at Singapore: third on GDP per capita and ninth on the Human Development

Index. Or Switzerland, ninth in GDP per capita and third on the HDI. Singapore is a teeny

tiny island, and Switzerland's main natural resources is cows. And cows are great! I love

cows, love love, but they aren't really natural resources.

Zimbabwe, on the other hand, has tons of natural resources, like fertile soil, coal and rare

minerals, but their economy? It's a wreck. It's a hundred and sixty first (161st) in

GPD per capita and a hundred and fifty sixth (156th) on the HDI. Their incompetent and

For comparison sake, the GDP per capita in the US is 18 times higher than in Bangladesh,

and we're not just trouncing Bangladesh. GDP per capita wise, we're also crushing the GDP

numbers of our great-grandparents. Take that, Aloysius!

The GDP per capita in the US today is about 8 times higher than a hundred years ago. That's

pretty impressive. Maybe the Thought Bubble can produce an explanation.

Mr. Clifford: Let's say John runs a bakery. Each worker to produce a dozen donuts per

hour, and each donut sells for $1. If John wants to stay in business, he can't pay his

Obviously, he needs to pay for the ingredients and the oven, but even if you wanted to be

generous, he couldn't pay them $20 an hour. They just don't produce enough for us to cover

the cost. But if John can find a way for each worker to produce four dozen donuts per hour,

he can pay them $20 per hour. Simply put, the more that each worker can produce, the

Economists argue that the main reason some countries are rich is because of their productivity.

Their ability to produce more output, per worker, per hour. US workers, altogether,

earn 18 times more per hour than Bangladeshi workers, because they're able to produce 18

times more output per hour. US workers today earn 8 times more per hour than US workers

a hundred years ago, because they produce 8 times more output per hour. But not only

is US producing more stuff, it's also producing higher value products, like Avengers movies

So going back to our bakery example, it's like a worker from a hundred years ago be

able to produce six plain donuts per hour, while workers today is able to produce 60

salted caramel designer cupcakes per hour.

Adriene: Thanks, Thought Bubble. Before we go further, we need to point out the limitations

of this bakery example. It's true, productivity is key. A country that is more productive

can create more stuff and can generate higher incomes, but in real life, it doesn't always

For example, in the US, the GDP per capita has been steadily increasing for decades,

but median family incomes haven't changed much at all. This gets to issues of income

inequality, and we're gonna devote an entire episode to it.

Limitations aside, low productivity remains a fundamental reason why some countries are

poor. Higher productivity not only helps explain why we have more money to buy stuff, but also

why we have more stuff to buy. And speaking of stuff to buy, because it is socially unacceptable

somehow for me to appear in the same clothes over and over, I need 40 blouses to make this

series. That is a lot of blouses. That strains resources, pollutes the planet, and at high

levels like 40 is completely unsustainable. Don't worry though, some of these are from

So what about people in poor countries? What do they need? Well, they need food, clothing

and housing, they need clean water and plumbing and sewers, they need hospitals and medicine,

but all those things have to be produced, so a country that produces more of these things

with fewer resources is gonna be wealthier and healthier, and perhaps even happier than

a country that can't. But making a million cell phones isn't very impressive if your

country has a hundred million people, so we need to look at how much stuff we produce

Mr. Clifford: So if everything all boils down to productivity, what makes some countries

more productive than others? Well, let's go back and look at the main ingredients that

we need to produce things, what economists call the factors of production.

First, you need land, which includes all natural resources, and then you need workers which

is labor, and then you need capital which includes machines and factories and infrastructure,

things you need to produce other things. One special type of capital is the workers' education,

knowledge and skills required to produce things. Economists call this human capital. So school's

not just about torturing you, except for PE, it's about helping your human capital.

The quantity and quality of these resources is the first step to being more productive,

but perhaps even more important is how you use them. Increasing the amount of capital

has a cost, but finding new ways to organize production is virtually free. Economists call

the organizational effectiveness "technology." Think of it as the good ideas about how to

combine labor and capital that you already have.

US workers produce so much more than Bangladeshi workers because the US has more factories,
