This book explores the thought of the three 'founding' members of the Austrian School of economics: Carl Menger, Friedrich von Wieser, and Eugen Boehm-Bawerk, considering the overlapping and specialization of their work on money, value, and capital. Offering an incisive overview of the work of three important, but often-neglected figures, the author sheds fresh light on the transition from Adam Smith's economics and the thought of the German School, to modern economic theory, considering also the influence of the Austrian School on the work of Max Weber. As such, it will appeal to scholars with interests in the history of ideas, economic theory, political economy, and social theory.
