"Your interest has much in common with my research field. I am a Sraffian and works in the field of international trade theory.I have not had a chance to read this paper. Based on the claims in the introduction, it does sound quite intriguing.
You have cited several times Steedman and Metcalfe. They have worked on the open small country case. As a trade theory, this is not general enough. It cannot analyse the South-North problem, to cite an obvious example. The Ricardian trade theory should be extended to the many country case with the traded commodities across countries. As Sraffa named his major work Productions of commodities by means of commodities, the production is circular in its character and cannot be arranged linearly as it is assumed in the Austrian tradition. Heckscher-Ohlin theory also assumes this linearity, starting with the endowed production factors, then sometimes intermediates goods and final goods. This is completely inadequate as production structure. But the task to develop a trade theory with this circular structure is quite hard. Steedman and Metcalfe did not succeed in this attempt. I recently found the method how to overcome this difficulty. Please look into my paper: A New Construction of Ricardian Trade Theory—A Many-country, Many-commodity Case with Intermediate Goods and Choice of Production Techniques" -- Yoyo_the_economist
