But why are the prices of food rising faster than the costs paid by companies (this is inclusive of all costs)? The naive assumption is that if all costs were originally x and prices were 1.1x, then as costs become 1.3x, prices become 1.1*1.3x. However, their profit margins as a percentage rose. So instead of 1.1 we now have 1.4.

Obviously the numbers used are fake, but this is why people are angry and it’s not something I’ve seen explained using economic principles that don’t involve terms like market consolidation at best or collusion at worst on any article. Rage sells so telling people their groceries cost more because there aren’t enough grocers or the grocers are collaborating is good business for newspapers as long as they can find an expert or group to make the allegations for them.

Can you use changes in monetary policy to explain why grocery store profits are higher than before? I would think that in the event of inflation stores would stabilize to profits that are roughly the same (percentage wise) as they were prior to the inflation occurring. To the best of my knowledge, this has not happened.

This is the first article I found, and in it they don’t mention any economic policy as a major cause.
