Provides an overview of the economics and political economy of transport security, considering its policy from an economic perspective. The author's analysis applies micro-economic theory to transport issues, supporting and enhancing the larger framework of our knowledge about personal, industrial, and national security. Button's focus on the economic aspects of transportation security strives to move beyond established technical and legal approaches, working within both the narrower microeconomics of individual and corporate efficiency and the larger trends in economic policy-making. By fitting current security trends into economic analysis, he discusses not only contemporary developments, but also their economic implications and approaches for assessing alternative strategies. This examination of applied economics is a must-read for those looking to gain a broader view of transport security issues. It is a critical resource for those in the security industries as well as those involved in education about transport, security matters, and applied microeconomics.
