The Productivity J-Curve
Brynjolfsson's framework for transformative technologies — the initial productivity dip during organizational adjustment, followed by a sharp rise as complementary investments mature into measurable aggregate gains.
The Productivity J-Curve is the dominant contemporary resolution of the Solow productivity paradox: transformative technologies produce a characteristic temporal pattern in which aggregate productivity initially declines or stagnates while organizations make the complementary investments required to realize the technology's potential, then rises sharply as the investments mature. The pattern has been documented for electricity, information technology, and is the predicted pattern for AI. Its relevance to Schor's framework is that the dividend's arrival is temporally delayed: even if AI delivers the productivity surge its advocates predict, the surge will arrive on a multi-year lag behind capability deployment, making the institutional window for capture even narrower than raw productivity projections suggest.

Brynjolfsson articulated the J-curve framework most fully in collaboration with Daniel Rock and Chad Syverson, drawing on historical analogies (particularly the electrification of American industry) and contemporary data on information-technology investments. The framework explains why the productivity statistics showed the 1987 paradox during early computerization and then the late-1990s acceleration:
