The Hidden Pattern in Gas Prices (And How to Beat It) | Diving In

Oil prices spike and pump signs change almost instantly. But when crude falls, the savings trickle in slowly — if they arrive at all. This pattern, known as "rockets and feathers," is real and measurable across decades of data. But does it prove oil companies are gouging you, or is something else entirely responsible?

In this episode, Justin Wolfers breaks down what the data actually reveal about gas price asymmetry, explores three plausible mechanisms that could create it — from consumer search behavior to tacit strategic interaction to supply chain dynamics — and explains why proving wrongdoing is much harder than spotting the pattern. Most importantly, he shows you when information actually matters: not on the way up (bad news travels fast), but on the way down, where checking a gas-price app or comparing nearby stations can help you find relief faster than waiting for the market to deliver it.
