This Note looks at the issues in the port sector, discussing the regulatory treatment of vertical and horizontal mergers. It focuses on Argentina, one of the first countries to concession its ports. In the early 1990s Argentina restructured and privatized its port system. As part of this process the government transferred ports to the provinces, which could choose to operate, concession, or close them. The Port of Buenos Aires was divided into two ports: Dock Sud, which was transferred to the province of Buenos Aires, and Puerto Nuevo, which remained under national jurisdiction.

The USA West Coast ports act as transshipment hubs either in an intermodal approach for the railway network linking them to the East Coast, or for the maritime routes connecting both sides of the United States via the Panama Canal. Several shipping lines operate both the Trans-Pacific and Trans-Canal routes with different types of ships (one ship type per route). The operating costs of the lines is minimized using a MIP model, determining the optimal number and type of ships in each line. In a second step, the transit time (including sailing and port operations time) is included. Using an estimation of the opportunity cost of time from other studies, we minimize the total cost, including both, operational and time costs. Delays are simulated both in the US West Coast ports and in the Panama Canal, analyzing the resulting economic and operational impacts. An optimal decision is reached as a tradeoff between operational and time costs, considering the associated effects of delays in the maritime and railway networks. Overall, our formulation allows the assessment of disruptive situations like port strikes, operational problems in the Panama Canal and others to the total shipment volume from a supply chain perspective

Time is a determinant factor in the logistics of the globalized production. Any delay in one of the supply chain intermediate steps can lead to bottlenecks affecting the production and/or distribution of goods and consequently, the time needed to reach markets. Therefore, the consideration of the time perspective is essential to any attempt of maritime logistics modelling. In this paper, a liner ship fleet deployment (LSFD) model is applied to a set of transoceanic routes connecting the port of Shanghai, as the only departure point in China, with several ports of the East and West coasts of North America, simulating the weekly containerized traffic between China and USA. The US West Coast ports act as transshipment hubs via the intermodal US rail system and/or the maritime routes to the East coast traversing the Panama Canal. Several shipping lines operate both the Trans-Pacific and Trans-Canal routes with different ships. The rail system is included with specific adaptations to the railways cost structure. We calculate the trade-off between shipping costs and transit time. Using the opportunity cost of time estimated in other studies, we identify the optimal combination of cost and transit time in terms of generalized costs for the importer. Our model assesses the impact of delays from various problems in the ports of the US coast in the China-US trade using a bicriterion formulation

A semi-structured questionnaire was administered to a sample of 1180 cruise tourists at one major port of call in the Mediterranean region. This allowed us to group cruise tourists into clusters, according to their characteristics, and analyse all the elements of two alternate types of behaviour. One group answered the questionnaire just after living the experience in the destination city; a second group, that already lived the experience in the same city, answered the same survey online. We also identified the aspects that most influence the global level of satisfaction, using ordered logit models. The findings, although drawn from only one destination, may be useful for practitioners and policy makers by allowing them to pinpoint and understand specific determinants of the socio-economic effects of cruise tourism on a destination, by taking into account the role of sustainable services. This study explores aspects overlooked by other studies by adopting a research model that goes beyond the traditional approach that has tended to focus on cruise tourists' satisfaction based on traditional services and facilities.
