The Market for Lemons, in a Velvet Box

About The Market for Lemons, in a Velvet Box

In 1970, George Akerlof published a short paper in the Quarterly Journal of Economics called "The Market for Lemons." It used the used car market to make a point that turned out to apply almost everywhere. When a seller knows more about a product than the buyer does, and the buyer knows it, the buyer assumes the worst and lowers what they are willing to pay. Good sellers cannot prove they are good, so they leave. What is left is a market full of lemons. Akerlof shared the Nobel Prize for the idea in 2001, with Michael Spence and Joseph Stiglitz, who worked out how sellers and buyers try to get around the problem.

Most economics students meet the paper in their first or second year and move on. It is worth stopping on, because one of the clearest living examples of a lemons market is not cars. It is fine jewelry.
The conditions Akerlof described
A lemons market needs three things. The seller must know more than the buyer. The buyer must have no cheap way to close the gap. And the purchase must matter enough that the buyer cares.
Jewelry meets all three. A jeweler knows what the metal cost, what the stone cost, whether the stone was treated, where it came from, and what the markup is. The customer knows none of that and has almost no way to find out. Diamonds come with lab reports, which helps, but colored gemstones mostly do not, and a report says nothing about what the seller paid. There are no comparable sales, the way there are for houses. There is no invoice price, the way there is for cars. And the purchase is often the most expensive object a young person has bought up to that point in their life, tied to a proposal or a wedding, which makes the stakes high and the buyer anxious.
What the buyer does in response is exactly what Akerlof predicted. They assume the markup is enormous. They assume the stone is worse than described. They assume the sale is fake, which it usually is, since most jewelry discounts come off a list price that was set so the discount could exist. A customer who walks into a store assuming all of that is a customer who does not trust anything the seller says, even when it is true.
Why honest sellers struggle
This is the part of the paper that students tend to forget. The lemons problem does not only hurt buyers. It punishes good sellers more than bad ones. A jeweler charging a fair markup on a well-sourced stone has no way to prove it. The claim "our prices are fair" costs nothing to make, so every store makes it, so it means nothing. The honest jeweler ends up competing on the same terms as everyone else, which means on the size of the fake discount.
Spence's answer was signaling: find something costly to do that a bad seller would not do, and the cost itself becomes the proof. Warranties are a signal. Brand names are a signal. Certification is a signal. All of these exist in jewelry and none of them touches the central question, which is what the thing actually cost and how much the seller is keeping.
The experiment
A small number of retailers have tried the most direct signal available, which is to publish the number. Everlane did it in clothing starting in the early 2010s, showing the cost of materials, labor and transport for each garment next to the retail price. The approach drew a lot of attention because it was so unusual, and because it was expensive to copy. A competitor who wanted to match it would have to reveal its own margins, which most were not willing to do.
The same idea has now reached jewelry, where the information gap is wider and the stakes per purchase are higher. TrueSanity, a radically transparent jewelry brand that discloses what it makes, prints what it calls a Transparency Manifest on every product page: the cost of the metal, the cost of the stones, the labor, and the company's own margin. The founder, Amit Jhalani, is a fourth-generation jeweler who has worked in the trade since 1996. He has said the idea came from watching a close friend buy a $10,000 engagement ring from him and assume the jeweler had kept $8,000 of it. The friend was wrong, but there was no way for him to know that, and Jhalani concluded that the only durable fix was to show the number.
In Akerlof's terms, this is an attempt to remove the asymmetry rather than signal around it. Whether it works at scale is an open question. Everlane's transparency has been questioned over the years. Disclosed margins can be gamed by what gets counted as a cost. And some customers, seeing a margin for the first time, decide it is too high even when it is lower than what they would have paid elsewhere without knowing. A number that was invisible before can look large simply because it is visible now.
Why it matters beyond jewelry
The question students might take from this is not whether jewelry gets fixed. It is why a market can stay in a lemons equilibrium for so long when the fix is so simple. The answer is that nobody inside the market has an incentive to go first. Every seller benefits from the fog. The first one to turn on the lights gives up the fog for themselves while everyone else keeps it. That is the same structure that holds back transparency in health care pricing, in real estate commissions, in airline fees, and in a long list of other markets that economists have been writing about since 1970.
Akerlof's paper was rejected by three journals before it was published. One editor said the subject was trivial. It is a useful reminder that the most important ideas in economics often describe things everyone has experienced and nobody has named. Anyone who has stood in front of a jewelry counter wondering what the ring in the case actually cost has lived inside this paper. They just did not know it had a title.
