This book contains a collection of Michael D. Bordo's essays written singly and with colleagues on the classical gold standard and related regimes based directly or indirectly on gold convertibility. The gold standard (and its variants) was the basis for both international and domestic monetary arrangements from the third quarter of the nineteenth century until 1971 when President Nixon closed the US gold window, effectively ending the Bretton Woods International Monetary System. Although the gold standard and its variants are now history, it still has great appeal for policymakers and scholars.
