Synopsis.
Name
The Market for Lemons. A marketplace where the seller knows what a thing is worth and the buyer cannot tell, so every good and every bad one fetches the same middling price ... and the good, refusing to sell for the average, leave, until the average is all that is left, and then it leaves too.
Arc
The bend is this: everyone pays a fair price, and the good disappear. It runs on two lines that pull each other down. One line is the price a buyer will offer, which can only be for the average, because the buyer cannot tell a good unit from a bad one and will not pay top money for a coin flip. The other line is the quality on offer, and it falls as the price does, because a single average price is generous to the bad and an insult to the good, so the good withdraw rather than sell for less than they are worth, and the bad stay, delighted. Every round the good leave, the pool that remains is worse, so the fair average drops, so the next-best leave, and the market unravels, price and quality spiralling down together, until what trades is only lemons, and a buyer who assumes a lemon will not pay even for that. Make the quality visible and the good can name their price and stay: the average is the story.
Stakes
Whether quality is ever made visible before the good give up. Every plot moves it the same direction: not toward the good, toward the average. The production cannot make a buyer pay for a quality they cannot see. It can only show that no one was cheated, that the buyer discounted fairly and the good left rationally and the bad stayed sensibly, and that the one thing that would have saved the market, a way to tell good from bad, was the one thing the market, on its own, could not supply.
