This paper examines the irreversible adoption of a technology whose returns are uncertain, when there is an advantage to being the first adopter, but a network advantage to adopting when others also do so. Two patterns of adoption emerge: sequential, in which the leader aggressively preempts its...

This paper develops a generalised model of network competition when consumers vary in their preferences for network size and location, and networks are vertically and horizontally differentiated. The effect of compatibility on the degree of competition between the networks is analysed. Two...

The increasing scarcity of water resources (in terms of quantity and quality) is one of the most pervasive natural resource allocation issues facing development planners throughout the world.This problem is especially prevalent in less developed countries where the management of this valuable...

The scarcity of water resources in both arid and temperate countries alike is one of the most pervasive natural resource allocation problems facing water users and policy-makers. In arid countries this problem is faced each day in the myriad of conflicts that surround its use.Water scarcity is a...

This paper describes global biodiversity conservation as a co-operative bargaining problem. We model an interdependent ‘technology rich’ North and a ‘gene rich’ South who must co-operate in the biotechnology sector in order to combine their unique and essential resources and maximise...
