I agree that the "capital side" (i.e. the composition of capital) is an important determinant of the rate of profit. (I prefer to discuss this in terms of Marx's concept of the composition of capital, rather than the mainstream concept of the "productivity of capital" which I think is misleading.) The increase in the composition of capital in the early postwar period was an important cause of the decline of the rate of profit in that period, and the decrease in the composition of capital in recent decades has been the main cause of the partial recovery of the rate of profit. So clearly, theory and analysis of the rate of profit should include the composition of capital. I also agree that this is an important distinguishing feature of Marx's theory, in contrast to Ricardo's theory and Sraffa's theory and all other economic theories, which if they consider the rate of profit at all, generally consider only the share of profit and ignore the composition of capital. > >............... > >6.

But I would add another important "recovery mechanism" which reduces the composition of capital and hence raises the rate of profit - bankruptcies of capitalist firms, whose productive assets are sold off to surviving firms at bargain prices, thereby resulting in the "devaluation of capital". Marx emphasiazed this as the most important mechansim to restore the rate of profit, since he regarded the increase in the composition of capital as the main cause of the decline of the rate of profit. But of course, in the short run, more bankruptices mean a deeper recession and perhaps a depression. So far, bankruptcies have not happened on a significant enough scale to fully restore the rate of profit. But Marx's theory suggests that that is what is required. > 2.

The increase in the profit share has bee quite modest since the 1970s, in spite of the wage-cuts, speed-up, etc. I don't think the "profit squeeze" theory provides an explanation of this surprising phenomenon. On the other hand, as I have argued, Marx's theory does provide an explanation - the continuing relative increase of unproductive labor. How do Dumenil and Levy explain the uptick in the "productivity of capital"? > 3.

Yes, as I have emphasized, these two points are entirely compatible. They are the two main causes of the decline of the conventionally defined rate of profit - an increase in the composition of capital and an increase in the ratio of unproductive labor to productive labor. > And if we do face such a period, it would not put capitalism "out > of the woods" politically.

I would also add another important element in the current situation, which I and Jim D. have emphasized in the past - the unprecedented levels of debt of all kinds (business debt, household debt, foreign debt) - which makes another period of sustained growth very unlikely. Indeed, this factor makes it more likely that this house-of-cards of debt will come crashing down in the not-too-distant future. Comradely, Fred
