Inflation and Greed

 Newshour is doing a program on corporate profits now.

There was a piece in the news today that mentioned the "rockets and feathers" effect, at least with respect to oil and gas. Crude oil prices can soar--the rocket effect--because the markets for crude are pricing the future.  Gas stations are slower to raise prices because of slack in the supply chain--current inventories were bought at lower prices.  

But while crude prices can fall quickly gas stations are likely to be slower to drop prices.

The wikipedia article also used crude/gas in the example.   I wonder about whether the effect applies much more widely.
