A new model that generates Lotka's law
Journal of the American Society for Information Science and Technology, 2001AbstractIn this paper, we develop a new model for a process that generates Lotka's Law. We show that four relatively mild assumptions create a process that fits five different informetric distributions: rate of production, career duration, randomness, and Poisson distribution over time, as well as Lotka's Law.

The explanation of this phenomenon is that the conditions for an application of the basic success‐breeds‐success model are not fulfilled

Price's contention is treated here as a hypothesis and assessed against the evidence presented by both empirical and simulated author productivity distributions. The
