Hi Rakesh I have responded to Ajit because it is normally more productive to discuss ideas with someone who disagrees with you. Hence less messages on your posts. >I think we may be the only two people on this list who worry that the >Sraffian view may depend on metaphysics-the false attribution of >timelessly physical or material existence to evanescent >technical conditions of production.

I think it's important to abstract and even freeze in order to analyse special-cases. So I have no problem in principle with formal models. On the contrary, I think they are essential. But always incomplete. Introducing change I think is essential to understand the theory of value. Best, -Ian.
