In the economics literature, various views on the likely (efficiency) effects of information exchange, communication between firms and market transparency present themselves. Often these views on information flows are highly conflicting. On the one hand, it is argued that increased information...

The Greenland infrastructure for the airborne traffic uses Kangerlussuaq, Søndre Strømfjord, as hub. New scenarios may change that, and one possibility is the construction of a large airport at Nuuk with a 3000 m runway. The trunk line will then be between Copenhagen and Nuuk. In that case the...

Samuelson (1958) analyses a three-period model, whereas Diamod (1965) considers a two-period model. This difference poses the question whether the insights derived by analysing the simple two-period model carry over in the more complicated three-period case. They do. The Samuelson model (no...

While hackers and viruses fuel the IS security concerns for organisations, the problems posed by employee computer crime should not be underestimated. Indeed, a growing number of IS security researchers have turned their attention to the ‘insider’ threat. However, to date, there has been a...

The focus is effects of investments in airports and runways on the market for air travel and more in general for the production possibilities of the economy. In the case of Greenland two types of impacts can be sorted out. One is more efficient production of air transport due to increased...

The paper defines a base model of the airborne passenger traffic to and in Greenland showing the number of passengers on every non-stop connection. The type of airplane is defined for each route, and that determines the flying time. The number of connections and capacity utilization are fixed...
