The link should be here, if Google was working: solow hft retail site:krugman.blogs.nytimes.com At the moment Google is acting as if Krugman never mentioned HFT or retail.

Am I allowed to make the joke that Solow’s Productivity Paradox is mostly explained by rampant link rot? But I’m only half kidding, because the rapid way technology breaks down is an obvious hindrance to productivity.
