I always like Jared Bernstein's accessible summaries of complex but profound topics like innovation and productivity. Both of these have large economic consequences, but also have significant, less-understood non-economic dimensions. Intangibles (e.g. software) and many services have "values" not fully, or perhaps even adequately, expressed in their price. What's the true value of a health worker's time that saves your life -- considered in either economic or subjective terms? What's the value of Marc Andressen's Mosaic (later Netscape/Mozilla) Internet Browser -- in a "market environment" where code could be copied for free?
Interesting to ponder Bernstein's own preference (despite affirming that "no one knows") for a possible market failure in the slowness of old industries to fully integrate new technologies. He also tends to give a push to demand-side explanations: e.g. there's less innovation and productivity enhancing products and services because people can't afford to increase their consumption at old rates.
