Military power and conflict have fuelled economic growth throughout history. Money matters to the military; it is needed to finance war and the desire to acquire it is often the motive for fighting. This book examines the interaction of economics and conflict, it explains the economic concepts used, and illustrates them with a range of military examples, both contemporary and historical. Among the many links explored lies the undeniable fact that fighting and finance are often both driven by the same basic human motives, fear and greed. 'Military Economics' draws on technical literature to provide an accessible introduction to: security, military expenditures, the arms industry, military operations and the economic consequences of defence spending. It raises current debates about the optimal size of the defence budget and examines how it is used to acquire forces, troops and weapons. The book examines how these forces are used to provide maximum military capability, and the potential to prevail in combat. Economic issues are central to the preparation for war, which involves balancing resources and commitments. By exploring the interaction between the military and economy, power and money, Ron Smith provides an insightful contribution to military planning, which becomes essential to the modern world. This book will be indispensable reading for all interested in defence economics, war studies and peace studies.
