The productivity puzzle – the debate continues Can intangible investment explain the UK productivity puzzle? A response and comment

This note responds to the recent critique by Goodridge, Haskel and Wallis (GHW) of our 2012 study of Britain's productivity puzzle. We show that a correct reworking of the latest official data on changes in labour composition overturns GHW's main criticism. We also question the strength of the empirical evidence offered by GHW in support of their alternative explanations of the productivity puzzle.
