Late one night time in 1989, economist Jeffrey Sachs discovered himself in a smoke-filled room of presidency officers in Warsaw, Poland. The nation had simply declared independence from the Soviet Union, which had exerted central management over costs of tens of hundreds of things, resulting in frequent shortages.
For tens of millions of Poles, that was a daunting proposition. Costs posted by the command-style authorities had been straightforward for peculiar folks to see and perceive, however the ideas of the free market had been an summary principle. It required religion to leap into the unknown world of provide and demand the place an unseen power referred to as “the invisible hand” would now regulate costs.
Sachs’ plan was put in movement the subsequent day, and newly unregulated costs of peculiar grocery objects instantly spiked, inflicting nervousness throughout the nation. The Polish finance minister, Leszek Balcerowicz, paced the streets, on the lookout for a glimmer of hope. He determined to focus on one factor: the value of eggs.
If the market was working, the upper value of eggs would create incentives for farmers to convey extra eggs to market, resulting in a fall in costs. Certain sufficient, in a number of days, egg costs started to drop. “That was an necessary day,” Balcerowicz recounted, a sign that the brand new free market was working its magic in allocating items and companies in essentially the most value efficient method.

However right here’s the unusual factor: the egg market will not be appearing in a method that financial textbooks would predict, and positively in a special route than Sachs’ assured prediction to the Polish folks.
There are two egg puzzles that go effectively past Econ 101 textbooks’ normal explanations of how corporations and shoppers work collectively. The solutions in the end give us a richer understanding of the complexities of people’ promoting and shopping for conduct.
What’s occurring right here? In puzzle #1, the scarcity of retail eggs and self-imposed retailer quotas point out extra demand. In puzzle #2, the elevated wholesale egg costs imply the next enter value for supplying retail eggs. Textbook economics predicts that in each circumstances, retail costs ought to be pushed increased.
Which means we ought to be paying no less than $8 a dozen, not $5, on common nationwide.
Some would possibly clarify that that is taking place as a result of eggs are a “loss chief,” that encourages prospects to purchase different worthwhile objects whereas they make their solution to the again of the shop, the place eggs and milk are usually offered.
There’s little proof this clarification is true for any size of time. The under determine charts the previous historical past of retail vs. wholesale egg costs. The orange line representing wholesale costs is nearly at all times under the retail costs in blue.
In reality, we see an attention-grabbing phenomenon: grocery shops solely lose cash on eggs when the wholesale costs spike up in a short time, as they briefly did in 2015, 2018, 2020 and 2023 as effectively. In any other case they’re making round an affordable 20-75 cents revenue per dozen, relying on the kind of eggs offered.
Determine 1. U.S. Egg Retail and Wholesale Costs, 2010-2023.
Since there was no value management on retail eggs a la the previous Soviet Union, we flip to the different clarification. A humble pack of a dozen eggs is probably going an emotional buy, no less than when the costs go excessive. We’re in contact with the costs of eggs as intimately because the Polish finance minister who wandered the streets, seeing them as a bellwether of the economic system as an entire.
Grocery shops have a tricky determination to make: they should weigh the price of their retail losses from egg gross sales versus the loss to their popularity if they’re seen as “villainous value gougers” in a time of quickly rising costs. It seems on this case no less than, grocery shops will take the short-term losses on the chin, as a result of they’ve hundreds of different objects the place the income can offset these losses.
Mockingly, shoppers could complain about sky-high egg costs in 2025, however they’re largely saved at nighttime about how protected they’re from the fact of far increased wholesale costs.
The quotas instituted by the grocery shops now make sense: the almost $3 loss per dozen eggs offered is sort of a retailer’s funding in retaining buyer’s goodwill, serving to restrict the injury from even increased priced eggs.
So it’s rational on the a part of the grocery retailer to distribute their eggs among the many largest potential buyer base by disallowing bulk purchases by particular person prospects. That method, they improve their popularity as a enterprise who cares for patrons and maintain their eggs out of only one buyer’s grocery basket.
The lesson: even in one thing so simple as an egg market, a fragile dance of emotion and popularity can intertwine with costs discovering equilibrium. In all circumstances, the extra competitors the higher, particularly underneath very long time frames. Shoppers stand a much better likelihood of being protected by corporations in these conditions than command economies or laws that create boundaries to entry for different rivals, corresponding to medical insurance markets.
That’s eggsactly what we must always want for. (I needed to get a nasty pun someplace).
