I do think AI will help, but ironically, it's by stretching an already creaking system to its breaking point and forcing it to reinvent itself. https://t.co/2klUukAIfu

Economist @joshgans uses o1-pro to generate a (minor, fun) paper in an hour based on an idea of his, and it gets published in an appropriate peer reviewed journal, with adequate disclosure. He ends with the same sentiment I am increasingly seeing from fellow academics: what now? https://t.co/tppV2H37UR

Despite digitalisation in the 21st century, productivity growth rates in advanced economies seemed to stagnate in the 2010s. One hypothesis to explain this phenomenon is the ‘productivity J-curve’, which suggests that the high costs associated with digitalisation during an investment boom induce an underestimation of productivity growth. This column tests the hypothesis using data from five advanced economies. It finds evidence that conventional total factor productivity growth rates in advanced economies were negatively biased in the 2010s, particularly in the US. These results have important implications regarding government investment support policies.
