During the 1980s, economists noticed that investments in information and communications technology (ICT) did not correspond with increased productivity. What is this phenomenon called?

Explanation

In the 1980s, despite significant ICT investments, productivity growth did not increase as expected, a phenomenon referred to as the 'productivity paradox.' This contrasts with terms like 'Solow residual,' which measures unexplained productivity growth, and 'technological lag,' which implies delayed adoption rather than lack of productivity gains.
