o The authors wish to express their gratitude to Octavio Rodríguez for his support in the preparation of this study, and to Oscar Burgueño for his collaboration in various discussions on this subject. Both these academics are researchers in the Institute of Economics of the Faculty of Economic and Management Sciences of the University of the Oriental Republic of Uruguay. It goes without saying, however, that the views expressed here are entirely the responsibility of the authors. 1 The term "model" is used here in a similar sense to that given to it by Schumpeter and therefore includes analytical formulations in any language: not just that of mathematics (see, in this respect, Vercelli, 1991, p. 15).
