“Throughout the book, Officer is a happy warrior whose enthusiasm for history and economics is infectious. … it should be read by anybody interested in PPP or in U.S and British monetary history. Most certainly, it should be read by those who use the long-run data series he creates. Outside of these areas it can be read with pleasure by those of us who enjoy seeing a master craftsman at work.” (John Devereux, EH Net, eh.net, July, 2023)
