Do Markets Dream of Artificial Intelligence? (DNB Working Paper) (www.dnb.nl)

A recent working paper titled "Do Markets Dream of Artificial Intelligence?" explores the macroeconomic impacts and international spillovers from AI news shocks, revealing significant insights into how these shocks affect financial markets in the U.S. and euro area. By employing a daily equity factor based on firms’ AI exposures and a Bayesian VAR model, the study identifies shifts in AI's expected economic value. Findings show that positive AI news leads to a notable increase in capital-goods orders in the U.S. while broader economic activity responds more slowly, characterized by rising producer prices ahead of consumer prices. The implications for the AI/ML community are profound, as the research illustrates that financial markets react swiftly to AI advancements, translating initial investments into economic growth—albeit with some uncertainty. In the euro area, positive AI news yields rising equity prices and contributes to inflationary pressures, underscoring the interconnectedness of global markets. The paper emphasizes a critical monetary policy challenge: financial spillovers occur prior to realized productivity gains from AI adoption, suggesting that policymakers must navigate complex dynamics where inflation expectations can escalate even before meaningful economic benefits materialize.
