Then, in line with the discussion above, to avoid rising unemployment, the demand curves need to be shifted out, raising MRs. This, BTW, is a simple case of wage-push inflation, of the sort that Sydney Weintraub used to write about. A quick tour though Henwood's Wall Street should convince you that modern corporate management will raise profits in any and every way it can short of actions so blatantly illegal that the cops will turn up before the loot has been banked. Pricing decisions are not made at a sectoral level, by the way. They are made at the individual firm and market level.
Aggregate prices are simply averages of the effects of micro-decisions.
I thought that Henwood showed that capitalists sought profit uber alles. If structural unemployment could be solved via training programs, for example, then the inflation barrier could be moved to lower unemployment rates.
