Presentation title: Is Generative AI Disrupting the Digital Economy? Early Evidence from Card Spending Data Suggests Not

Abstract: Generative artificial intelligence raises concerns about human jobs, but what about other products and services? If customers “hire” products to “do jobs,” is generative AI threatening the services that perform those jobs? We investigate a large card spending panel to understand how early ChatGPT-4 adopters changed their spending on other digital services. We use later cohorts of ChatGPT-4 adopters to predict early adopters’ counterfactual spending and apply a triple-difference identification strategy with Coarsened Exact Matching. We find that ChatGPT-4 adoption increased consumer spending on other AI products. Our estimates rule out market share changes of 1% for the large majority of brands, with a few exceptions. We will present more results during the talk.
