In this paper, we construct a model of market structure in the global arms industry linking concentration, military procurement, international trade and regional conflict. We show how concentration depends on the willingness of producers to import for their military needs and on the relative...

We examine strategic procurement behaviour by governments and its effect on market structure in sectors, such as defence, where the government is the dominant consumer. In a world economy with trade between producers, and between producers and non-producers, we use a modified Dixit-Stiglitz...

We analyse the role played by Export Credit Guarantees (ECGs) to encourage exports to developing countries. The existence of moral hazard on the side of the firm is introduced. We show that the inability of the exporter's government to verify the actual quality of the product will limit its...

We consider conflicts between an incumbent, e.g. government or dominant firm, and potential challengers, e.g. guerilla movement or entrants. It is not uncommon for challengers to win such conflicts despite their lack of resources. They can do this by exploiting a second mover advantage: choosing...

Administered Incentive Pricing (AIP) of radio spectrum as advocated by Smith/NERA (1996) and recently assessed by Indepen (2003) envisages an incremental path towards e±cient pricing, with revealed and stated prefer- ence methods being used to reveal opportunity costs. We build on the latter to...

We investigate the potential economic effects of spectrum trading amongst firms who require spectrum licences as part of their activities. Trading takes place within the technical interference constraints enforced by a regulator. The model accommodates a variety of markets and firms, as well as...

Treating spectrum of different bandwidths as essentially distinct inputs needed for possibly different types of services has formed the core of spectrum analysis in academic research so far. New technological advances, such as cognitive radio, now allow us to move away from this inflexibility...
