Stock, Crave and Even

Stock spoke first, because a market begins with the simple question: how much is there?

Stock's whole nature was supply — how much of a thing got made and brought to be sold. And Stock knew that the amount was never an accident; it came from the choices of everyone who produced. "This morning the farmers had a choice," Stock said, gesturing at the red crates. "Berries were selling well last week, so more of them planted, picked, and hauled berries in today. When something's worth bringing, more of it shows up." Stock pointed to a lonely half-crate of winter squash. "And squash sold badly, so barely anyone bothered. That's supply — not a fixed thing, but a living answer to the question 'is it worth bringing?' Today, the answer for berries was a great big yes. Look at them all."

Then Crave moved through the buyers, because a pile of goods means nothing until you know: how much do people want it?

Crave's whole nature was demand — the pull of what people wanted, and how much they'd give up to get it. And Crave could feel it like weather. "The berries — everyone wants these. Sweet, in season, kids tugging sleeves. Strong want." But Crave also felt the edges of the wanting. "Though — watch. If the price climbs too high, some of these buyers will sigh and walk away. They want berries, but not at any price. And squash?" Crave drifted past the lonely crate. "Barely a flicker. A few people need it, most walk right by." Crave turned back. "Wanting isn't all-or-nothing. It bends with the price. The higher the cost, the fewer who'll pay — the lower the cost, the more who'll reach for it. That bending is the whole shape of demand."

And now the two great forces faced each other — a big supply of berries, a strong-but-bendable want for them — and Even stepped into the middle to do the one thing neither side could do alone: find where they agree.

"Neither Stock nor Crave sets the price," Even said, chalk moving. "I don't even set it. It settles — right at the spot where the amount for sale matches the amount people will buy." Even worked it out on the little board. "Price the berries too high, and Stock's crates sit full while buyers walk off — too much supply, not enough takers. Price them too low, and every berry's snatched in a minute while latecomers find empty crates — too much want, not enough berries." Even landed on the middle number. "But here — right here — the berries for sale and the berries wanted finally match. Crates empty out just as the last willing buyer pays. That's the meeting point. Not one side winning. Both sides agreeing." And because berries were plentiful today, that meeting point sat low and friendly — lots of supply, so a gentle price.
