Approximation of a Continuous Core-periphery Model by Core-periphery Models with a Large Number of Small Regions

Abstract For a continuous core-periphery model, we construct model with n regions for each $$n\ge 2$$ n ≥ 2 . Assuming that the known functions of and diameters converge to 0 respectively as number tends infinity, this paper proves approximate relations between models large small when are in short-run equilibrium.
