Popular economics hit the bestseller list in 2005 with Steven D Levitt's Freakonomics, which sold by the bucketload and established a template that, for the time being at least, no aspiring economic populariser would dare to tamper with. Certainly, Tim Harford's The Logic of Life and Robert H Frank's The Economic Naturalist stick closely to Levitt's formula - right down to their subtitles, which promise, as Freakonomics did, that economics will explain "everything" or, in Frank's case, "almost everything".
My review of The Economic Naturalist by Robert H Frank, The Logic of Life by Tim Harford and The Dismal Science by Stephen A Marglin appears today in the Guardian.
