This research project focused on the the profound but poorly understood changes in the international security environment that had taken place since the end of the Cold War This project aimed to undertake a set of tightly linked theoretical and empirical studies of the determinants of military expenditure ( which has fallen rapidly since the peak of the mid 1980s) and its effect on economic growth  of procurement and the regulation of the arms trade (both of which had become increasingly competitive)  and of arms production (where the industry was being massively restructured)
