Population Dynamics in a Microfounded Predator-Prey Model
This paper analyzes the dynamics of a two-dimensional microfounded predator-prey model. It is shown that the dynamics closely resemble those of a model commonly used in mathematical biology if parameters of the latter are suitably restricted. The positive equilibrium of the microfounded model is globally asymptotically stable for positive initial values largely irrespective of the parameter values chosen. If a version of Allee’s Law is included, however, species extinction becomes possible.
