The regional specialization via differences in transport costs are observed in Japanese manufacturing industries. Concretely, industries with high transport costs for their products, such as iron and steel, petroleum and coal products, remained close to the core region while industries with low...

This paper examines a new economic geography model with multiple (three) industries and urban costs. The industries are asymmetric in their transport costs. The following results were obtained. First, if transport costs sufficiently decrease whereas commuting costs are constant, we have three...

In the literature of new trade theory, most papers study the industrial location by imposing the assumption of free transportation in the agricultural sector. This paper explicitly incorporates arbitrary transport costs in both the manufacturing and the agricultural sectors into the...
