Here's another book that's good either for browsing or for reading all the way through. English author Harford has in this volume written a chapter of five or six pages about 50 inventions that shaped the modern economy. I was not surprised to find that all this takes place in exactly 50 chapters. Included are many obvious inventions, like the elevator, air conditioning, clocks, paper, batteries, etc. But there are also many that I never would have thought to be inventions, although I have to acknowledge that they were, like management consulting, intellectual property, tax havens, and insurance. The fact that this book is written in a breezy, entertaining way makes it appealing to a wide range of audiences.
