Problem:
An apparent discrepancy between the investment in IT and macro-measures of productivity was observed late in 20th Century in what became known as the Productivity Paradox (Pinsonneault & Rivard, 1998). Indeed, the computing capacity of the U.S. increased a hundredfold in the 1970s and 1980s, yet the macro-level productivity growth slowed down from over 3% in the 1960s to roughly 1% in the 1990s.
How do you think about that?
