This paper reexamines Simons model which formulates the stochastic processes yielding the Yule city size distribution. First, in conjunction with the empirical fact that the form of city size distributions is stable over time, the concept of the “steady state” stated by Simon is clarified. Second, Simons assumptions and the “steady state” are shown to be contradictory. Third, however, it is shown that this contradiction is disolved in the context of the “asymptotic steady state”. Based on these reconsiderations, fourth, Simons model is reformulated. Last, in the context of this reformulated Simons model, the “steady state” is reconsidered.
