Wheelan, a Chicago-based correspondent for the Economist, has decided to shake the dust off economics, making the case that it is not just an arcane academic science but a practical set of tools. Though he admits that many of us are "economically illiterate," his book is "not economics for dummies, it is economics for smart people who have never studied economics (or have only a vague recollection of doing so)." Eschewing jargon, charts, and equations, Wheelan gives us the essentials.
