I guess one way it’s surprising is that, it takes a degree of coordination for this to happen. I mean you have some major international event that can trigger international economic consequences like some degree of inflation and then some genius thinks that since the public have been forced to swallow price rises across the board because of this, what if we just raise our prices some more and it will be assumed it’s for the same unavoidable cause. Okay, I get the scam, great. But, whether consumers believe the pretense or not and have sympathy or not, wouldn’t stop them going elsewhere if someone else didn’t come up with the same clever scheme or hasn’t launched it yet, and still has higher, but not extra high prices. Or maybe they do all see a great caper and jack up the prices at the same time, eventually, for the same greedy reasons, those businesses would want to take the other’s lunch if they could and would see the benefit of being at least just a little bit cheaper which is supposed to create a cycle that is the way capitalism supposedly works.

This doesn’t happen when you see monopolies or near monopolies. Supermarkets in Australia are in particular being talked about for price gouging and there’s an associated near duopoly between 2 dominant chains. In that context it’s definitely not very surprising. I’d bet that this particularly recent example of price spikes without adequate explanation are associated particularly with sectors where there is very little competition. The article was pay walled so I can’t tell if they’re referring specifically to prices for groceries or economy wide problems.
