By his own admission Matthew Hennessey is an unlikely author of an economics book. He has no experience in business, accounting, or finance. Until fairly recently, he was quite intimidated by the dismal science. Yet he’s managed to become the Wall Street Journal’s deputy op-ed editor, so he likely knows a thing or two about markets. Over the course of 200 entertaining pages, he proves it. Visible Hand is the elementary economics book we’ve been waiting for. I don’t mean it’s an Econ 101 text of the kind college freshmen wearily slog through. It’s something much more important: an everyman’s introduction to how property rights, prices, and profits and losses make the world go ‘round. I hope we can get copies of this book in the hands of every high school senior in the country.
