We present a model of transnational terrorism where two countries, home and foreign, face a terrorist threat based in the foreign country. The home country chooses how much to invest in defending itself or in reducing terrorist resources either indirectly by subsidising the foreign country or by...

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 consider conflicts between an incumbent, e.g. government or dominant firm, and potential challengers, e.g. guerilla movement or entrants.

Given that there are a relatively small number of suppliers of major weapons systems, control fo arms exports is possible, and there are a variety of regulatory regimes striving to achieve this. Controls can stabilize regional arms races and reduce tensions. However, when buyers can develop the...

Multinational arms export control has been the subject of discussion in a variety of fora, from the United Nations through to the Wassenaar group of arms producers. It is widely recognised that free trade in arms can have negative externalities on national security and there are benefits from...
