Spatial Discounting, Fourier, and Racetrack Economy: A Recipe for the Analysis of Spatial Agglomeration Models
TL;DR: In this paper, an analytical approach that facilitates understanding the bifurcation mechanism of a wide class of economic models involving spatial agglomeration of economic activities is presented. But the proposed method is limited to the multi-regional core-periphery (CP) model.
