NBER Paper: GenAI Faces Oligopoly, Open Ecosystems Need a 'Rogue' Giant

A recent NBER working paper delves into the competitive landscape and economics of open versus closed generative AI models.

The study argues that because incumbent firms can tightly control complementary assets like compute, the market structure is likely to become highly concentrated. This restricts newcomers to subordinate roles and stifles broad sectoral innovation.

The authors suggest that the best hope for a vibrant open-source AI ecosystem might be a "rogue" technology giant that uses openness as a strategic weapon against other incumbents.
