Sean Ennis, Henri Piffaut Insular Economies : An overview of the national case law


Insular economies have a specific set of competition challenges that may differ from those in larger, better-connected economies. The purpose of this foreword is to outline, at a high level, the nature of the trends and challenges faced in such places. It is not the purpose of this foreword to summarise the many cases that have been produced by the relevant authorities, an analysis that would have a very different character. We note first that, while the exact definition of an insular economy is flexible at the boundaries, the primary criteria for being classified as insular constitute distance from traditional centres of economic activities and, very often, relatively modest size that imply that, economically, economies of scale and scope that are present in large economies cannot be achieved in these geographies. In this note, for reasons of geographic coherence, we will take a particular focus on Australia, Fiji, French Polynesia, New Caledonia, New Zealand and Papua New Guinea.
