Hello Paulo, YOur question is, I think, an old one -- and a good one! My answer -- in order to give *both* the New Classical *and* the New Critical positions some space to work with -- is that a demand increase causes P to rise, even though income is short of full-capacity utilization, due to: bottlenecks, speculative behavior, whatever. (I can't use pressure from the side of the labor market in the context of the New Critical Dobb Effect arguemnt.) It might be possible to imagine that more intensive use of a given stock of physical capital causes diminishing returns and upward cost pressure on prices. Productivity in the sense of output per worker thus falls, a change in productivity that occurs even though we are in a period in which technical change is not being implemented. Again, I am assuming no more and no less than the models of the standard macro texts. The AD shift pulls prices up along a rising short-run AS curve. The question then is, which way does this curve shift? All I am suggesting is that by bringing into the picture the effect of the price increase on the "entire position" (Dobb) of the workers, we find AS shifting to the right -- a huge de-centering of the standard dogma that Y tends to Y* and P alone is driven by AD. The door is now open for consideration of a range of *political-economic" effects of policy, i.e., a move in the direction of a political economy of government policy (cf the superficiality of the mainstream view), and therefore toward a Marxist analysis of the capitalist conjuncture, or short run. I do not propose that my intervention in macro theory is a *substitutte* for that actual Marxist analysis! But it may help us to think about what that analysis may contain.
