Competition and efficiency in a spatial setting

Article Abstract:

A spatial model of competing firms in a regional industry is developed and described. The firms studied are located in an area that gains exclusive access to a dispersed raw material input. The form of the industry long-run average cost curve was outlined. Results demonstrated that the industry long-run supply curve does not coincide with the industry long-run average cost curve. It was shown that the outcome in spatial models results from the separation of firms, with each firm having its own domain.

Equilibrium and disequilibrium perspectives on regional labor migration

Article Abstract:

Migration models have been categorised as either being in equilibrium or disequilibrium. A mathematical model has been designed to show migratory flows. There can be times when areas seen as having stationary equilibrium can also have large migration flows. Studying the dynamics of that population and the local conditions can result in a necessary review of migration and the remaining population.

A long-run interpretation of regional input-output analysis

Article Abstract:

The use of most regional input-output analysis (I-O) models are restricted to Keynesian short-run markets. However, an investment-endogenous I-O model was used to generate a long-run equilibrium similar to those extracted from short-run I-O models. Sensitivity analysis was used to determine the speed of adjustment in the new model and a neoclassical model tracking the same equilibrium.
