But it's come at a cost. For the Freakonomics radio network, this is the economics of everyday things. I'm Zachary Crockett. Today, cashmere. If you are a goat in Central Asia, every winter you grow a second coat of hair underneath your outer coat. It's soft, it's fluffy, and it's around six times finer than human hair. This wool is called cashmere.

Carolyn Yim (3:24)

The softness is on the belly and the little areas under the arms and the chin.

Zachary Crockett (3:30)

Carolyn Yim runs Plyknits, a boutique knitwear company based in New York and Hong Kong. Her family has been in the textile business for three generations.

Carolyn Yim (3:41)

I think the reason it's so prized is because it's beyond a functional product. It is a good that is associated with luxury and an elevated sense of style.

Zachary Crockett (3:53)

That association, she says, started back in the 1960s.

Carolyn Yim (4:02)

How it came to be, well, I would say a lot of the association this with old money. Cashmere, like the cashmere, is worn at Ivy Leagues and the cashmere sweaters with like cigarette burns into it. And then in the 2000s, there was a lot more democratized cashmere. That started to happen. And that's when we really started to see that everyone wanted a cashmere sweater.

Zachary Crockett (4:29)

These days, around 30 to 40 million pounds of raw cashmere are harvested each year all over the world. In Afghanistan, Tibet, Iran, Australia, New Zealand. But 90% of the world's supply is comes from China and Mongolia. In Mongolia, where Miga lives, herding was once a collectivist enterprise. But when the country's communist system was replaced by a democracy in 1990, the goat herds were privatized and families flooded into the herding business. Today, tending to Kashmir goats is Mongolia's largest profession.

Miyagmarjav Miga (5:12)

We have over 3 million population and 1 third of the population I heard of.

Zachary Crockett (5:18)

Miga manages the Mongolian sustainable Cashmere platform for the United Nations. In short, she spends a lot of time working with herders. While goats in neighboring China are raised on farms, Miga says Mongolian herders are nomadic. They migrate across vast distances, sometimes hundreds of miles, in search of food for their goats.

Miyagmarjav Miga (5:43)

They are land connected people. They love their animal and livestock. They also love their nature. Early in the morning, they herd the animals and take them out to the pasture. They move a lot. They always go seeking for better pasture for their animals.

Zachary Crockett (6:01)

The cashmere is harvested with metal combs every spring and weighed out in grams. That's the standard used for international trade. On average, a goat might produce 250 grams of raw cashmere each year. The price that it fetches is governed by its color and its quality. But in general, Miga says that one goat might yield around $10 worth of cashmere. That means that it takes a herd of 500 goats to earn Mongolia's median household income of $5,000. Most herders breed new Goats to ensure they have a sustainable cashmere business.

Miyagmarjav Miga (6:38)

Each season, springtime, they collect the cashmere. Then when it comes to slaughter season in November or early December, they slaughter the animal and sell the meat to the market.

Zachary Crockett (6:54)

Mongolia has seen tremendous inflation over the past 30 years. An item that cost the equivalent of a dollar in 1993 costs around $95 today. So even with supplemental income, it's hard to make ends meet.

Miyagmarjav Miga (7:10)

Economic return is not sufficient enough to cover their financial demands. Herder family, for instance, have five children, four of them gone to this school. And the herders have to pay all that expenses in the capital city, which is now very expensive.

Zachary Crockett (7:28)

In theory, herders could make more money if they sold their cashmere directly to processing mills. But their options are limited by Mongolia's geography.

Miyagmarjav Miga (7:38)

It's a vast country. You can imagine how much effort needs to be to collect all the raw material.

Zachary Crockett (7:45)

Traders from China travel through the far reaches of Mongolia on motorbikes, collecting bags of cashmere from herders. These middlemen clean the cashmere and sell it to mills for around $100 per kilogram, more than twice what they paid for it. A portion of this raw cashmere stays in Mongolia, where it's knitted into goods by local companies. But 80% of it ends up in China. Mega wishes Mongolians could do more of that work themselves.

Miyagmarjav Miga (8:15)

Mongolia don't fully benefit from the Kashmir industry because of this insufficient processing capacity in the country.

Zachary Crockett (8:24)

So how does all this cashmere get turned into sweaters, scarves, mittens and even underwear? That's coming up.

Once cashmere is collected from herders, it makes its way all over the world. Some higher end brands like Loro Piana, export the material to Italy, where it's knitted in local factories. But most Mongolian cashmere ends up in China, where full scale milling operations turn it into yarn. It goes through a process called carding, which draws the fibers out into strands.

Carolyn Yim (10:14)

It is like a really, really long Santa's beard. It's really nice and fluffy.

Zachary Crockett (10:19)

Carolyn Yim, the third generation knitter, has visited the factories in China many times.

Carolyn Yim (10:25)

This then is taken into the spinning machine where the hair is twisted in two ways. Kind of like a DNA structure that becomes twisted and twisted until it becomes a really long and that is finally then put onto the cone and becomes usable for knitting.

Zachary Crockett (10:47)

By the end of this process, the cashmere is about 50% smaller. So it can take a lot of goats to make a single article of clothing.

Carolyn Yim (10:56)

At the end of the production cycle, each sweater takes about one pound of yarn. If you're just measuring grams, it's about five or six goats for one sweater.

Zachary Crockett (11:12)

Yim's company, Plyknits, uses this yarn to produce all kinds of cashmere goods. Cardigans, leggings, shirts, most of which cost a few hundred dollars apiece. But not all cashmere is created equal. The gold standard is pure white, with strands that are 14 microns wide and 36 millimeters long. And buyers like Yim have to develop a sixth sense for sniffing it out.

Carolyn Yim (11:38)

I think over time, my sensitivity with my hands has really grown. It's sort of like being a perfumer with a nose. A really good cashmere sweater will feel peachy or creamy plush, whereas a bad cashmere sweater is dry, cardboardy, papery thin.

Zachary Crockett (11:59)

Cashmere goods were once a luxury, produced in small batches and priced out of reach for most consumers. But in recent years, cashmere has entered an era of mass production. A new crop of Companies sells 100% cashmere sweaters for well below $100, supposedly by buying the material directly from herders and cutting out the middleman. But Yim says some brands keep prices down by using less material or by making their sweaters from lower quality fibers.

Carolyn Yim (12:31)

You're taking not just the hair from the belly, you're taking areas that you wouldn't have before to make up for that demand, and then using Methodology afterwards, such as different ways of bleaching. I think this is happening a lot now. Even with high end brands. The luxury cashmere sweater today is not the same as what it was 20 years ago.

Zachary Crockett (12:59)

Mongolia has responded to this boom in demand by cranking up cashmere production. Since 1990, the country's goat population has exploded from 5 million to 27 million. That's had an impact on the landscape. Goats consume up to 11% of their body weight in grass, shrubs and weeds every day. They eat close to the roots, preventing plants from regrowing. Their sharp hooves damage topsoil. Scientists have found that overgrazing has contributed to the degradation of 70% of Mongolia's grasslands. Migus says Mongolian officials have attempted a number of things to combat these issues, including livestock taxes to fund revegetation.

Miyagmarjav Miga (13:46)

They know that the land is foundation for everything, their livelihood and their animals. They're not stupid. They are willing to pay that money and they realize the issues.

Zachary Crockett (14:00)

In northern China, measures have been more drastic. Most herding operations have been confined to.

Carolyn Yim (14:06)

Farms in recent years. The Chinese government has a very particular approach to how the flocks can live. The goats are in corrals so that they are not roaming around free.

Zachary Crockett (14:28)

And the region faces an even graver climate change. Most of Mongolia's landscape is made up of dry lands that are prone to becoming deserts. Temperatures are up, rainfall is down, and factories that produce cashmere garments are under pressure to adapt new sustainability standards. Environmental permits can cost hundreds of thousands of dollars. Yim says that in some major production hubs in China, these costs have put up to 50% of small to medium sized knitwear manufacturers out of business in the last five years. Even the most diligent operations are struggling to comply.

Carolyn Yim (15:11)

I do not have the hubris to claim I have 100% sustainability because it's completely impossible.

Zachary Crockett (15:20)

Together, increased demand, overgrazing and climate change mean that Kashmir is getting worse.

Carolyn Yim (15:28)

I'm unable to find the quality that we had 20 years ago. In Inner Mongolia, the cashmere fiber width has been steadily increasing. And that's not a good thing. You can't just increase yield of goat hair so quickly to meet up with demand.

Zachary Crockett (15:49)

These are prickly issues for something as soft as a baby's butt. But Mongolians like Mika are invested in creating a sustainable future for the trade because cashmere is more than a material used to make really soft sweaters. It's a part of the country's identity.

Miyagmarjav Miga (16:13)

This nomadic way of herding practice has been in the country hundreds, hundreds of years. The international demand is going up. The country has to control in terms of impact, environmental impact, social impact, and also economic impact for that commodity. That's a lot of challenges.

In Mongolia, they wash it with just shampoo or with detergent. And it's just everybody wears it.
