Shipping's fourth wave: ship management and Vernon's trade cycles

This paper considers the question whether the present recovery of shipping means a return to pre-crisis conditions with hegemony of OECD shipping or whether shipping has irrevocably changed. Shipping is losing its national character as ship management firms contribute towards the fragmenting of traditional ship-owning firms into separately managed activities, making shipping more footloose as an industry and facilitating relocation in least cost factor markets. Trade cycles may be at work in shipping like those observed in many industrial markets, beyond the scope of any single government's ability to control. The dispersion of shipping and shipping firms away from the historical concentration in a few traditional maritime powers towards low-cost countries must be seen as a manifestation of a secular trend, giving rise to a profound reorganization not only of shipping markets but of shipping itself.     

The Nigerian shipping industry and indigenous shipping companies

The shipping industry in Nigeria since the early 1990s has been experiencing a continuous disastrous downturn. Nigerian shipping companies' participation in international shipping has continued to be very limited. Their presence and impact is hardly felt in the world's shipping industry. Both the national carriers (that is shipping companies with national carrier status) and other indigenous private shipping companies have vessel as well as management problems. These problems have led to the poor performance of the Nigerian shipping industry for over a decade now. The carriers in the industry are not attaining for the country the gains that are supposed to emanate from shipping. This paper points out the importance of shipping to a nation, identifies the problems the country's shipping companies are facing and proffers solutions that include merging of the companies to have strong financial standing and a competitive edge.

Risk perception affecting the performance of shipping companies: the moderating effect of China and Korea

Risks in the shipping industry have been highlighted and have attracted significant attention, especially following the bankruptcy of Hanjin in 2017. Due to the decrease in container volume, the business environment for large shipping companies in China has deteriorated. Therefore, major large shipping companies have implemented mixed ownership reform, which provides more opportunities for large Korean shipping companies to enter the Chinese shipping industry. This study first identifies risk perception, specifically focusing on the moderating effect of Chinese and Korean shipping companies, and then demonstrates the impact of these risks on shipping company performance. The results show that market, operational, and technical risks have a negative influence on Chinese shipping companies, whereas market, policy, financial, operations, and technical risks have a negative influence on Korean shipping companies. This study contributes to the fundamental understanding of the effect of risk perception on performance among shipping companies in both countries and calls for further research on risk management plans based on the risk factors identified herein. On a practical level, this study provides an important reference for operators and investors who seek to enter strategic alliances or joint venture in Chinese shipping industry.     

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.
