Basically when inflation hits and input costs rise, prices rise, but by a higher amount. It's pretty intuitive. If you're going to change the price due to an increase in costs, why not increase it a bit more and then just blame it on inflation? Or, if costs come down later, why reduce prices unless you have to? This is why inflation is can be so stubborn, increase costs in a single input can ripple though the system, then cycle back and increase costs even further (say cost of labor).
