Further, it could be argued that if one uses Kantorovichs method one can
extract marginal returns for each input which are not the same as the average returns his ODVs.
But the underlying model remains linear and tractable.

Hi Michael W:
Yes, but don't most Marxian models also assume constant returns to scale?
I suppose this would be legitimate in a static model, but surely any
truly dynamic model of growth and capital accumulation must not assume
this. This must be the case since technological change in means
of production and the processes of the centralization and concentration
of capital require (and, indeed, express) economies of scale.
In solidarity, Jerry
