The Economics of Everyday Things, Episode 11: Cashmere

Host: Zachary Crockett (Freakonomics Network)
Date: February 5, 2026

Overview

This episode dives into the hidden world of cashmere—a luxury material most closely associated with high-end sweaters, but deeply entwined with the economies, landscapes, and cultures of Mongolia and China. Host Zachary Crockett explores the journey of cashmere from nomadic herders in the Mongolian steppe to boutiques in New York, illuminating the surprising economics, environmental costs, and changing standards of this now-commoditized good.

Key Discussion Points and Insights

The Mongolian Origin of Cashmere

• Mongolia’s Goat Population and Economic Role

  • Mongolia is home to 27 million goats—eight times the number of people—whose cashmere undercoat has become a mainstay of the country’s economy.
  • Cashmere is collected once per year in spring; an average goat yields about 250 grams annually, worth around $10.
  • Quote: “Cashmere is a primary income source for herders, but also an important pillar of the country's economy.” – Miyagmarjav Miga, [02:42]

• Nomadic Herding Lifestyle

  • Mongolian herders are nomads, moving hundreds of miles in search of pasture.
  • Herding includes collecting cashmere in spring; goats are often slaughtered for meat in late fall.
  • Quote: “They are land connected people... They always go seeking for better pasture for their animals.” – Miyagmarjav Miga, [05:43]

• Post-1990 Economic Shift

  • After Mongolia’s transition from communism to democracy in 1990, goat herding became privatized, and the population of goats exploded.

Cashmere’s Luxury Status and Global Expansion

• Luxury to Mass Market

  • Cashmere has shifted from an exclusive good (think $2,000 Loro Piana turtlenecks) to everyday wardrobe staple (with brands like Quince and Everlane offering sweaters for $60).
  • Quote: “In the 2000s, there was a lot more democratized cashmere... that's when we really started to see that everyone wanted a cashmere sweater.” – Carolyn Yim, [04:02]

• Cashmere Production & Quality

  • Most raw cashmere flows from Mongolian herders to Chinese traders, who sell it to mills—often at a significant markup.
  • Only 20% of Mongolian cashmere is processed locally; the majority is exported, which Miga laments as a missed opportunity for local economic benefit.
  • Quote: “Mongolia doesn't fully benefit from the Kashmir industry because of this insufficient processing capacity in the country.” – Miyagmarjav Miga, [08:15]

The Making of a Cashmere Sweater

• Processing Techniques and Yield

  • After combing, raw cashmere is carded and spun into yarn; the final product is about half the mass of the starting fiber.
  • It takes the undercoat of 5–6 goats to make one sweater.
  • Quote: “At the end of the production cycle, each sweater takes about one pound of yarn... about five or six goats for one sweater.” – Carolyn Yim, [10:56]

• Assessing Quality

  • High-end cashmere is prized for its softness and fiber length/width (gold standard: pure white, 14 microns wide, 36mm long).
  • Quote: “A really good cashmere sweater will feel peachy or creamy plush, whereas a bad cashmere sweater is dry, cardboardy, papery thin.” – Carolyn Yim, [11:38]

• Mass Production & Corner Cutting

  • Lower-price brands keep costs down with inferior blends, using coarser body hair or chemical bleaching.
  • “The luxury cashmere sweater today is not the same as what it was 20 years ago.” – Carolyn Yim, [12:31]

Environmental Consequences and Sustainability Challenges

• Overgrazing & Land Degradation

  • To meet global demand, Mongolia’s goat population jumped from 5 million to 27 million, intensifying overgrazing and damaging 70% of grasslands.
  • Goats’ eating habits and hooves exacerbate soil erosion and prevent plant regrowth.

• Response Measures

  • Mongolia has implemented livestock taxes to fund revegetation, but infrastructure and processing limitations persist.
  • Chinese government confines herding to corrals to limit roaming and degradation.

• Climate Change Pressure

  • Mongolia faces desertification, rising temperatures, and reduced rainfall—worsening the sustainability crisis.

• Factory Sustainability Costs

  • Modern environmental regulations are pricing small and medium Chinese knitwear makers out of the market.
  • Quote: “I do not have the hubris to claim I have 100% sustainability because it's completely impossible.” – Carolyn Yim, [15:11]

The Future of Cashmere

• Declining Quality & Ongoing Challenges

  • Median cashmere fiber width is increasing—a sign of lower quality due to breeding for volume.
  • Quote: “I'm unable to find the quality that we had 20 years ago... You can't just increase yield of goat hair so quickly to meet up with demand.” – Carolyn Yim, [15:28]

• Cultural Importance and Hopes

  • Amidst environmental and economic turmoil, cashmere production remains central to Mongolian identity.
  • Quote: “This nomadic way of herding practice has been in the country hundreds, hundreds of years... 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.” – Miyagmarjav Miga, [16:13]
