Container shipping on the Northern Sea Route

Since the beginning of the 20th century, the principal commercial maritime routes have changed very little. With global warming, the Northern Sea Route (NSR) has opened up as a possible avenue of trade in containerized products between Asia and Europe. This paper verifies the technical and economic feasibility of regular container transport along the NSR. By adopting a model schedule between Shanghai and Hamburg, we are able to analyze the relative costs of various axes in the Asia–Europe transport network, including the NSR. While shipping through the Suez Canal is still by far the least expensive option, the NSR and Trans-Siberian Railway appear to be roughly equivalent second-tier alternatives.     

Network Effects and Infrastructure Productivity in Developing Countries*

This study proposes to investigate the threshold effects in the productivity of infrastructure investment in developing countries. It concludes to their presence in the relationship between output and private and public inputs as well as network effects in the productivity of infrastructure. When the available stock of infrastructure is low, investment has the same productivity as non‐infrastructure investment. On the contrary, when a minimum network is available, the marginal productivity of infrastructure investment is greater than the productivity of other investments. Finally, when the main network is achieved, its marginal productivity becomes similar to the productivity of other investment.     

Libéralisation des Services publics de réseau et jeux croisés de la régulation: le cas de l'électricité

This article analyses the liberalization of public services with a special focus on the (re)regulation process that is induced. Firstly, a conceptual framework is developed in order to identify the constitutive elements of the public regulation related to market competition, public service obligations, operators and public property, as well as the tension between them. Secondly, a comparative study describes the liberalization and the regulatory design of the electricity sector in England, France, Germany, Norway and Switzerland. As a conclusion, we note the necessity to further analyse the introduction of market mechanisms into formerly monopolistic network industries and its effects.     

Grocery retail loyalty program effects: self-selection or purchase behavior change?

In the retail sector, consumers typically patronize multiple outlets for a variety of products, which raises the important issue of how outlets can gain a greater share of consumer expenditures. One such way is to increase repeat purchases through loyalty programs. This article examines the impact of loyalty programs, which target existing customers, on repurchase behavior in grocery stores. It finds that heavier, more frequent customers of a store enroll in the loyalty program earlier; that buying behavior changes only slightly after buyers join the program; and that small changes in loyalty appear to erode 6–9 months after buyers join.     

The Valuation of MNC International Operations During the 1990s

We investigate how international operations affected firm value during the early 1990s. We also investigate whether the disclosures of foreign operations in specific geographic regions under SFAS No. 14 provide investors with useful information beyond disclosure of aggregate foreign operations. We find that in the early 1990s, investors do not value international operations as highly as domestic operations, and that geographic region disclosures are not useful for conveying information about the specific location and magnitude of the firm's operations. This latter finding supports the recent FASB decision that eliminated the requirement that firms break out foreign operating statistics by geographic region.
