The Great Stagnation
Cowen's 2011 thesis that developed economies exhausted low-hanging technological fruit after 1970—median wages flattened, productivity growth slowed—until AI, mRNA vaccines, and GLP-1 drugs ended the stagnation around 2020.
Tyler Cowen's
The Great Stagnation (2011) argued that apparent innovation since the 1970s masked a deeper reality: the transformative, broadly-shared productivity gains of prior eras—electricity, automobiles, antibiotics, mass education—had been picked. What remained was incremental improvement delivering marginal benefits to narrow populations. Median household income stagnated. Productivity growth decelerated. The internet changed how people consumed entertainment and communicated but did not change the median wage. Cowen later identified the stagnation's end around 2020 with the arrival of mRNA vaccines,
large language models, and GLP-1 obesity drugs—a cluster of genuinely transformative innovations breaking the forty-year pattern. The question for the 2020s is whether societies can capture the growth these innovations make possible, or whether institutional bottlenecks will convert technological breakthrough into another round of disappointing aggregate statistics.

The stagnation thesis was controversial because it challenged Silicon Valley's self-conception. The technology industry believed it was transforming civilization. Cowen's data showed it was mostly transforming leisure—faster phones, better streaming, more addictive social
