The article discusses the concept of 'Productivity J-Curve', which explains how intangible investments complement general purpose technologies (GPTs) and can lead to underestimation or overestimation of productivity growth in early and later stages of GPT adoption. The authors propose a model that accounts for these dynamics, using market value regressions to estimate the magnitude of unmeasured intangible capital investments related to R&D, software, and computer hardware. They find substantial effects on total factor productivity (TFP) growth, particularly from software-related intangibles, which have led to understatement of TFP levels since the 1990s.
