I don't think we can put a number on it, but what we can say with some confidence is that when inflation was low and stable.... We have had big shocks to input prices and we've had big fluctuations in energy prices in the last 25 years, and what we saw when those things happened was that businesses were pretty cautious about passing on the higher energy price into the prices they charged, not for gasoline, but for other goods and services. When we would ask them about that, they'd say “Oh, yeah, we can't just pass these on or we're going to lose customers, and we don't want to lose customers.”
When inflation went way up lately, though, what we started to hear from businesses was, “Oh, it's much easier to pass on these price increases.” That's exactly what you see in the data. When input prices went up—the cost of energy, for example—those increases were passed through much more quickly into the final prices of goods. Households are bearing the full inflationary impact much more quickly. That's what we can see pretty clearly in the data.
