----------------- HES POSTING ----------------- I would like to add to Jan Pieter Schulz's question. I have for some time been putting a similar question to historians of economic thought. Specifically, I ask: I have had a long standing problem with Cambridge economists (for me, starting with Joan R.) who criticize neoclassical economics by asserting that neoclassical theory has an essential assumption of perfect knowledge or perfect information. Since Alfred Marshall explicitly denied such an assumption in his Book 6, do you have any idea, as an historian of economic thought, where any (or the first) proponent of neoclassical economics actually made such an assumption? My suspicion is that this is a can that has been tied to the tail of neoclassical economics by the critics. Lawrence A.
