In this paper, we model a manufacturing and transport sector use export volumes to determine the demand for services. If trade exceeds particular level, service suppliers maximise profit by investing in an advanced technology, which lowers their marginal costs reduces equilibrium prices. Transport thus vary according two characteristics: distance between locations endogenous firm decision inves...

H transport costs pose a significant barrier to development in africa. Causing friction in the movement of labour and goods, transport costs effectively reduce the markets for labour and goods, and for the transmission of knowledge and technologies. Reducing transport costs in contemporary Africa has become even more of a priority, with many countries having reduced tariffs on their internation...

Innovations that reduce costs of transport from rural locations may also reduce transport costs to rural areas. As transport costs fall, producers can afford to concentrate and achieve economies of scale. This paper explains an initially negative, but ultimately positive, relationship between reductions in transport costs and rural development. A two-region general equilibrium model with firm a...

Sedimentation is one of the most important problems in harbors that results in considerable economic costs. Harbor planforms affects the flow pattern in the harbor basin and consequently, plays an important role in sediment transport and sedimentation. In the present study, a two dimensional depth-averaged hydrodynamic and sediment transport model has been developed to investigate the effect of...

Transportation costs are of central importance in the New Economic Geography literature, though assumptions about transportation costs continue to be simplistic. This paper begins to address these simplifications by assuming that transportation costs for manufactured goods are heterogeneous. Basic results are consistent with standard models showing dispersion of economic activity for high trans...

The real costs of trade – the transport and other costs of doing business internationally – are important determinants of a country's ability to participate fully in the world economy. Remoteness and poor transport and communications infrastructure isolate countries, inhibiting their participation in global production networks. Recent liberalizations have reduced artificial trade barriers, and ...
