Tails of explosive birth processes and applications to non-linear P ólya urns
Thomas Gottfried, Stefan Grosskinsky
We derive a simple expression for the tail-asymptotics of an explosive birth process at a fixed observation time conditioned on non-explosion. Using the well-established exponentia…

Wages and Capital returns in a generalized Pólya urn
Thomas Gottfried, Stefan Grosskinsky
It is a widely observed phenomenon that wealth is distributed significantly more unequal than wages. In this paper we study this phenomenon using a new extension of Pólyas urn, mod…

Asymptotics of generalized Pólya urns with non-linear feedback
Thomas Gottfried, Stefan Grosskinsky
Generalized Pólya urns with non-linear feedback are an established probabilistic model to describe the dynamics of growth processes with reinforcement, a generic example being comp…
