On a relatively recent thread, probably several different ones, it was mooted that the pandemic was likely to drive prices of pens down. Lots of complicated reasons for it, such as retailers suffering cash flow issues and so on. That said, I've not really noticed this happening, and it seems that at the higher end prices may even be going up - perhaps for the same reason?

There's also something else I don't really understand. In a competitive market pen sellers are going to be price takers, their prices are going to reflect what the market dictates, but on eBay (as an example) there are sellers who act as though they are price makers , even though they are not a monopoly and are still in a competitive market. I feel that I am missing some important analytic point here; if someone would like to illuminate that would be great.
