looking at your paper Ajit I am not surprised by the results. Whenever I have attempted to run such dynamic input output models, since my masters thesis in 1975 I have always found the instabilities your mention. Frequently they become so severe that the reproduction of the system fails because one of the industries in the basic sector closes down.

I think it is directly relevant to 90% of the debate on this list. We would welcome all critical as well as 'friendly' comments: The abstract is given below: In this paper we use insights from Sraffa's classic, PCMC, to argue that the classical notion of 'centre of gravitation' is not a sound concept. The market mechanics of labour allocation through price signals and quantity adjustments, given effectual demands, do not lead to a 'centre of gravitation'. We work out all such possible market mechanisms, including the specific classical case, and show that the 'centre of gravitation' is a non-attractive point in all the cases.
