Economist Robert Solow famously said in 1987 that the computer age was everywhere except for productivity statistics. Wikipedia has a pretty good article about this Productivity Paradox.
One hypothesis I've heard that isn't on the Wikipedia page is that productivity from IT also requires new kinds of organizational structures. If you had many layers of middle management, and replaced paper memos with email, it wouldn't necessarily improve productivity because that wouldn't harness the full potential of computing.
