The impact on productivity growth of discrete innovations, such as the light bulb, fades when the market saturates. General-purpose technologies (GPTs), such as the electric dynamo, affect growth over longer horizons through knock-on innovations that enable additional applications. Inventions in the method of invention (IMIs) fuel growth through new ideas that translate into productivity gains. Emerging evidence indicates that genAI is both a GPT and an IMI and, thus, can be expected to have a sustained positive impact on productivity. ## About this publication **Ranked journal.** A peer-reviewed journal in the RePEc ranking of economics journals, below the leading ones.
