Abstract: By considering hypothetically the Bradford distribution, as a dynamic system developing in time on the principle formally equivalent to that proposed by Simon, it was shown that though the Simon generating mechanism gives rise to certain qualitative features ascribed to data, the resulting distribution function, derived as a steady‐state solution of the proposed stochastic process, is too restricted to cope with the variation produced in time. The empirical evidence, combined with the results of goodness‐of‐fit test, strongly support this fact, showing explicitly that the changes in the shape of the distribution that appear in the course of time, particularly the changes in the low producing tail, reduce excessively the scope of the model marking the limits of its applicability. © 1998 John Wiley & Sons, Inc.
