Abstract: The framework adopted in the paper is that of the Sraffian theory of the choice of techniques. Under the assumption that demand is price-independent, the uniqueness of cost-minimizing techniques is analyzed in terms of relations between square neighboring techniques. It is shown that, for certain types of economies, uniqueness is guaranteed if and only if all cost-minimizing techniques have the same 'color.' The color of a technique depends upon the rates of profits and growth, and the characteristics of the processes that constitute a technique. The result is extended to economies using natural resources. Copyright 1995 by Blackwell Publishers Ltd and The Victoria University of Manchester
