Asymptotic stability of equilibrium is often difficult to know when the number of variables exceeds four, since all eigenvalues of the Jacobian matrix are not analytically solvable. However, we obtain stability conditions for a general class of migration dynamics without computing eigenvalues....

This paper analyzes a two-region model including multiple industries with different transport costs. Two results are derived. First, dispersion occurs for small transport costs, but the specific dispersion patterns depend on the level of urban costs. This results from an interaction of the...
