Roberts is "Marxist economist," whose background I think is in Trotskyism of some type. I generally find his "economic" proposals to be way too Keynesian for my taste, or what I consider to be "Marxist"-- see for example his stuff on Cyprus and Greece-- replete with "People's Banks" or some equivalent thereof.

So I said on the OCC thread that I would put considerations on the Kliman et al response and Heinrich's MR paper on here, where it belongs.
First, in relation to Heinrich's MR paper, I find that his specific counter-argument (the (s/v)/(c+v) stuff) to the LTRPF section is faulty. Including for some of the reasons Kliman points out (and arguably Marx did as well), i.e. that s/v is not a fraction of two independent variables, but a ratio that can be at most 100% of a limited variable - hours worked in a production period (day/whatever). However, the tangled mess that Heinrich gets himself into in the last two paras of that section (beginning: "However, this conclusion is only correct if the capital (c + v) necessary to employ the two workers is of an amount at least as great as that required to employ twenty-four workers before.") actually could be made to make sense IF you drop the assumption of the OCC, i.e. that VCC in socially-aggregate constant capital is increasing. Kliman's argument that Heinrich's account presupposes the "dis-accumulation of capital" is based precisely on this micro-level OCC technical/value slippage, and on the macro-level "physicalist" error that capital can only be accumulated in the form of fixed and constant production capital, and not the financial and commodity moments of the full value-in-process cycle delineated in Vol II.*
Which really brings us on the meat of the disagreement between Heinrich and Kliman et al (and the whole neo-orthodox position as a whole, I submit) - that is on the question of whether Vol III actually contains a completed theorisation of credit - i.e. whether Marx's capital is "complete" or not. And here I side very much with Heinrich. For e.g. this appears to me to be broadly correct:
The Kliman et al paper responds with a true confessio de fide in its Section IV "The Theoretical Completeness of Marx’s Crisis Theory" (even the title asserts it).
So there we have it - the "Complete Marx", nothing important left unfinished in the book on Capital. A complete theory of credit must either therefore be found within it, or be irrelevant.
And that, for me is the real dividing line. Any project for going beyond the incompleteness of Marx, for a real and useful theorisation of interest-bearing credit and financialisation (as something other than a evidence of decay) is prohibited from the outset, by the insistence on the completeness of Capital as a total, "scientific" theoretical deconstruction of capitalist dynamics. And in this day and age, that for me, is fatal.
* I'm tempted to call the considerations of the fuller composition of capital at a macro level, the "inorganic composition of capital", precisely to get away from this physicalist limitation.
