Great buzz in the blogosphere over Chris Giles’s attack on Thomas Piketty’s Capital in the 21st Century. Giles finds a few clear errors, although they don’t seem to matter much; more important, he questions some of the assumptions and imputations Piketty uses to deal with gaps in the data and the way he switches sources. Neil Irwin and Justin Wolfers have good discussions of the complaints; Piketty will have to answer these questions in detail, and we’ll see how well he does it.

There is no obvious upward trend. The conclusions of Capital in the 21st century do not appear to be backed by the book’s own sources.(More here.)
