Sheech, what a poor counterpoint to an extensive body of intellectual work created by fellow resident colleague. I wonder if they ever talk! Just based on personal recall, the main gist of Gordon's research is that 1) growth of productivity is the main driver of economic growth, GDP; and 2) that except for the period 1995-2000, strong productivity both in and out of the the computer et al. sector, compared to mid 20th century, is simply not to be found. Some have argued that productivity may be mis-measured. Mr. Mokyr seems to simply ignore the main issue entirely; i.e. where is the growth? It's possible that we're moving into an era where traditional measures of growth (GDP) fail to measure significant forms of economic improvement. In healthcare, for example, successful treatment does not seem to be a component of efficiency, yet it's the raison d'être of the entire enterprise! Obviously economic growth, GDP, is not the golden grail, longevity and quality of life are things that matter; more than improvements in digital gossip even. Mokyr, in my view, has simply failed to address the issues in anything other than a facile fashion.
