In 1919 Mises published Nation, State and Economy, where he utilized the tools of economic analysis to address questions related to foreign policy. He would discuss foreign affairs again in works such as Liberalism (1927) and Omnipotent Government (1944), and there are paragraphs found throughout Human Action (1949). Other colleagues of Mises utilizing the tools of economic reasoning to assess the military and foreign policy include Lionel Robbins and Oskar Morgenstern. In more recent years, Robert Higgs stands out for his work in this area.
Though over the last decade, Chris Coyne and his colleagues such as Peter Leeson, Rachel Mathers Coyne, Thomas Duncan, Adam Pellillo and Abigail Hall Blanco, have in journal articles and in books carved out the contemporary research program in this area. Last year (2016), the Institute for Humane Studies released through their Learn Liberty series a set of videos discussing these issues featuring Abigail Hall Blanco and Chris Coyne. And, their forthcoming book, Perfecting Tyranny: Foreign Intervention and the Loss of Liberty at Home (Stanford University Press) will be required reading for all concerned citizens.
