Artificial intelligence and economic growth in G20 economies: investigating nonlinear effects through a GMM method
This study investigates the non-linear impact of artificial intelligence (AI) on economic growth in 19 G20 countries, using data from 2005 to 2023 and employing the Generalized Method of Moments (GMM) with both linear and quadratic models. The linear model indicates that AI-related innovation has a positive and significant effect on economic growth, while the negative quadratic term confirms a concave relationship between AI and growth. Regarding the effects of AI interactions with various mechanisms on economic…
