Regional Economies of Scale in Transportation and Regional Welfare
AbstractA discriminatory tariff can be welfare superior to free trade in the presence of regional economies of scale. This is because a tariff on non-regional trade concentrates trade within a region, lowering the cost of transportation, so that the gains from economies of scale can theoretically offset the losses from the tariff. To complement the theoretical point I estimate the relation between transportation cost and regional volume of trade. The estimates suggest that a 10% increase in the volume of trade brings about 2.5% reduction in transportation cost in the long run.
