In this sequel to Gold: the Once and Future Money, Nathan Lewis describes the theoretical basis of gold‐​standard monetary systems. Lewis argues that the pre‐​1913 world gold standard system was perhaps the most successful monetary system the world has ever seen, enabling high levels of economic growth. Descriptions of both Britain’s economic rise under the gold standard and the United States’ rise to economic prominence under gold are also discussed. Lewis offers the technical details necessary to implement and maintain a gold‐​standard system. Join us for a lively discussion of monetary history and a glance into one possible monetary future.
