Refracted Continuous-State Branching Processes: Self-regulating populations

Probability 2016-12-01 v4

Abstract

We construct a modified continuous-state branching process whose Malthusian parameter is replaced by another when passing below a certain level. The construction is obtained via a Lamperti-like transform applied to a refracted L\'evy process. Infinitesimal generator, probability of vanishing at infinity, of explosion and some path properties are also provided.
