Wang\n\nTandon Family Professor of Business Admini stration at Harvard Business Schoo\n\nWhen LLMs Go Abroad: Foreign Bias in AI Financial Predictions\n\nDate: Friday\, December 19\, 2025\n Time: 10:3 0 AM – 12:00 PM\n Location: Bronfman building\, Room 245\n\n\nAbstract\n\nW e document foreign biases in AI-generated financial predictions: ChatGPT ( US-based) is systematically more optimistic about Chinese firms than DeepS eek (China-based)\, predicting higher end-of-year stock prices and generat ing more buy recommendations. This AI-specific phenomenon contradicts the traditional home bias in which investors favor domestic assets. We trace t his bias to differential information access: ChatGPT's optimism increases when US media coverage of Chinese firms' negative news is scarce relative to Chinese media. Supporting this mechanism\, placebo tests with synthetic Chinese firms without such asymmetries show no prediction gap between mod els. Crucially\, providing ChatGPT with Chinese news through prompts-which cannot alter model weights-completely eliminates the prediction gap\, dem onstrating that the bias stems from missing training data. Our findings im ply that the parallel development of LLMs in different countries can creat e divergent financial forecasts\, potentially amplifying rather than reduc ing cross-border information asymmetries as these tools shape investment d ecisions globally.\n DTSTART:20251219T153000Z DTEND:20251219T170000Z LOCATION:Room 245\, Bronfman Building\, CA\, QC\, Montreal\, H3A 1G5\, 1001 rue Sherbrooke Ouest SUMMARY:Accounting Academic Area Workshop Series: Prof. Charles C.Y.
