I am convinced that Prof. PASINETTI is on the road to important and Interesting results; on the other hand I agree with Prof. DorRFMAN ‘hat his attack on earlier theories and his survey of historical nature is not only unnecessary in this connection but also partially unjust. But I do not want to go into that because I would need an hour to explain my argument. You want to construct your model independent from the allo- cation problem, But growth and allocation belong together; they are inter-dependent things and I have an uneasv feeling that you overlook this interdependence PASINETTI Professor SCHNEIDER is right, of course, in saying that optimum allocation of resources and economic growth may not be independent of each other. I do not think, however, that they are necessarily dependent on each other. For example, I can well conceive of an economic system where allocation of resources is optimum, and yet there is absolutely no economic growth whatever. At the same time, I can well imagine an economic system where economic growth is very fast and yet there is misallocation of existing resources. For myself, T have chosen to investigate economic growth first of all. AILAIS I have not had the time to study the paper sufficiently carefully and I have only one question to ask, though there is some discus- sion of the point on page 47.
