Does anyone actually understand inflation?

A pugnacious paper sets off a debate about the role of expectations in shaping prices

FOR ECONOMICS writing—a genre that stylistically is often closer to computer manuals than to literature—a discussion paper recently posted on the Federal Reserve’s website is a blessed relief. Jeremy Rudd, a Fed researcher, includes quotations from William Butler Yeats and Dashiell Hammett. He uses such phrases as “ill-tempered pettifogging” and “arrant nonsense”. And, as if channelling David Foster Wallace, he has fun in his footnotes, notably one in which he casually observes that mainstream economics may serve as “an apologetics for a criminally oppressive, unsustainable and unjust social order”. Little wonder his paper has become, by central-bank standards, a social-media sensation.
