Rail and multi-modal transport

This paper elaborates on the definitions of inter and multi-modal transport, as well as their differences in terms of performance. A survey of the barriers, both internal and external, to an efficient intermodal transport is included followed by an analysis of the advantages and disadvantages of combining rail transport with the other transport modes. Transhipment technologies for efficient freight service and some examples of freight rail corridors between sea and inland terminals are presented. The integration between air and rail transport is discussed and the potential synergies between air and high-speed rail services are emphasised. The paper concludes with a discussion on energy use for sustainable rail performance.     

A transaction cost analysis of Finnish, Swedish and Norwegian shipping

The purpose of the article is to analyse the operation of shipping companies in Finland, Sweden and Norway cross-sectionwise in 1989-1991. These represent three different types of shipping operations in three neighbouring countries in Northern Europe. In the analysis, an apllication of the transaction cosr approach (TCA) is employed. It is shown that finnish shipping is usually very concentrated both in terms of geographical coverage, cargo composition and ownership. In cargo shipping, Finnish shipping firms mainly operate on the 'domestic' routes connecting Finland to the main European markets. Few Finnish firms are operating in highly competitive operations such as cruise shipping and liquid and dry bulk trades. Ownership in shipping is also often institutionalized rather than being in private, independent hands. In Sweden, the hierarchial governance of shipping is less than it is Finland. In certain worldwide trades, such as reefer and car carrier trades, the governance structure could be defined as hierarchial due to high asset specificity and high degree of specialization. In Norway, the shipping industry seems to be strongly market-oriented. The industry is composed of shipping companies, whose existence depends on their cost competitiveness on the shipping market, and is usually not backed up by exclusive hierarchial arrangements. Notable exceptions are the LNG/LPG and car carrier trades. The classification presented principle can easily be extended to other shipping countries, or companywise comparisions, as well.     

Financing and charging for seaport and airport infrastructures in France

This paper questions responsibilities for the financing of infrastructure for sea and air transport in France. It is stressed that the State accords differential treatment in aid and subsidies to these means of transport and distinguishes between types of infrastructures and superstructure. Some principles concerning charging practices are discussed. Finally, the power of decision in financing infrastructure is examined and, in conclusion it is found that, while some public financing is necessary, this should follow a strict policy.

Ports and shipping in Mozambique: current concerns and policy options

This paper explores the current state of ports and shipping in Mozambique, and reviews it in the context of a past history of civil war followed by radical macro-economic adjustment, and more recent concerns and debates around the deregulation and privatization of the transport industry. More specifically, it addresses the key issue of the relationship between shipping and both broader and local economic development, taking account of the needs of major industry and the need to sustain local livelihoods. It reveals that the situation in Mozambique is a product of both local and global pressures, moulded by economic and political forces. It further indicates that, while there are now positive opportunities for coastal shipping, the capacity for developing inland shipping appears to be very limited. Future growth consequently depends on local participation, training and skills development and the broader social, economic, and transport infrastructure.
