Economic turmoil has spread throughout the western world, but terrorists and other threats to national security have not been put out of business by the Great Recession. Economic Instruments of Security Policy explores the critical question: does the United States and its allies still maintain effective economic tools to influence the behavior of those who seek to cause us harm? Governments have at their disposal many economic instruments to promote national security, such as sanctions, foreign aid, international trade, international finance, and laws blocking funds for international terrorism. This book examines the use of theses economic policies and addresses how best to measure their effectiveness.
