Perhaps. But, nonetheless, isn't it the case that all the significant
theorizing about monopoly and oligopoly pricing (even Sweezy's "kinked
demand curve") has taken place on an entirely Marshallian basis? And
where is Marx's theory of secular change (inflation/deflation) in the
price level? Isn't it rather the case that Marx's deep interest was
not in prices at all, but rather in the laws of motion of the
capitalist mode of production and most especially in the "Law of the
Falling Tendency of the Rate of Profit" and its effects?"
^^^^^ CB: I respect your extensive investigation of these issues to a thesis level, but if Marx was so especially interested in "the law of falling tendency of the rate of profit" it would seem he would have gotten it into the Volume One of Capital that he published and /or would have finished at least that part of Volume III before dying. It seems likely that he would have gotten all the issues he considered most fundamental and important to understand the laws of motion of capitalism into what he published; not left them in notes for Engels to publish.

Of course we should--within the context of those laws of motion and their concrete *present* manifestations.
