Demand, Supply, and Market Equilibrium

An oil shock in the seventies cut supply by only about a tenth—yet prices almost quadrupled. In this episode, we drop you into that moment. Why did a “small” change unleash such chaos, and why does the same hidden force shape your rent, your groceries, even your used car?

Step away from oil for a second and look at something closer to your daily routine: that streaming subscription you almost canceled last month, the rent that jumped just as your lease renewed, or the used car that somehow costs more than a new one. None of these prices are random, and they aren’t set by “greedy companies” alone. They emerge from millions of decisions—who’s willing to pay what, and who’s willing to sell or produce at what cost.

Now layer in shocks: a new city regulation on short‑term rentals, a sudden boom in remote work, or a missing chip in a global supply chain. Each one nudges people to change their plans—move, delay a purchase, switch products—and those tiny adjustments ripple through markets.
