Description
Summary:We determine the properties of the core‐periphery model with three regions and compare our results with those of the standard 2‐region model. The conditions for the stability of dispersion and concentration are established. As in the 2‐region model, dispersion and concentration can be simultaneously stable. We show that the 3‐region (2‐region) model favours the concentration (dispersion) of economic activity. Furthermore, we provide some results for the n‐region model. We show that the stability of concentration of the 2‐region model implies that of any model with an even number of regions. Determinamos las propiedades de un modelo núcleo‐periferia de tres regiones y comparamos nuestros resultados con los del modelo estándar de dos regiones. Se establecen las condiciones para la estabilidad de la dispersión y la concentración. Al igual que en el modelo de dos regiones, la dispersión y la concentración pueden ser estables simultáneamente. Mostramos que el modelo de tres regiones (dos regiones) favorece la concentración (dispersión) de la actividad económica. Además, aportamos algunos resultados para un modelo n‐regional. Mostramos que la estabilidad de la concentración del modelo bi‐regional implica eso mismo de cualquier modelo con un número par de regiones.
