Stability of Totally Agglomerated Equilibrium in a Multiregional Core-Periphery Model

We study multiregional extension of Krugman's Core-Periphery model. Comprehensive characterization of agglomeration stability is obtained in terms of the basic parameters of model. In particular, conditions of uniqueness of the stable total agglomerated equilibrium were obtained. The main feature of this paper is that the considered model is asymmetric, i.e., uneven allocation of the immobile (agricultural) population across regions is allowed. Unlike the previously known results for asymmetric CP model, which were based on numerical simulations, this research is quite analytical.
