Yesterday morning I attended an URPE session at ASSA in Chicago titled,, "Marx, Rawls, and Sraffa, and the Limits of Mainstream Economics." The Rawls person did not appear, but there was a paper on recent J.B. Clark award winners as reps of mainstream econ. Lots of attention on Daron Acemoglu, with people arguing about whether what he is doing is good or not. Wisecrack I heard was that "MIT economists are rediscovering insights of Marx, Kalecki, and Steindl, but not citing them." This paper was presented by Robert Chenomas of U. of Manitoba.
The main debates came from presntations by Robin Hahnel and Michael Perelman. The big whoop is that the archives of Piero Sraffa are now being made available. This is engendering a massive search into his long secret writings with various proposed reinterpretations going on. A big issue is his relationship with Marx, with Hahnel claiming an FST vs an FMT, a Fundamental Sraffa Theorem vs a Fundamental Marx Theorem. The argument is that in a proper input-output Sraffa type system any commodity can be the "source of value," with the Marx argument being that it must be labor. Well, all hell broke loose, and I shall not leak who was carrying on more than whom.
What is clear is that we are going to be hearing more about this now that those long held archives have been opened.
