9 kwietnia, 2024

The Institute of Finance at PUEB is pleased to announce the 14th Online Seminar in Finance.

Speaker: Sebastian Müller, Technical University of Munich

Title: Global Business Networks

Abstract: We leverage the capabilities of GPT-3 to generate historical business descriptions for over 71,000 global firms. Utilizing these descriptions and advanced embedding models from OpenAI, we construct time-varying business networks that represent business links across the globe. We showcase the performance of these networks by studying the lead-lag effect for global stocks and predicting target firms in M&A deals. We demonstrate how masking firm-specific details can mitigate look-ahead bias concerns that may arise from the use of embedding models with a recent knowledge cutoff, and how to differentiate between competitor, supplier, and customer links by fine-tuning an open-source language model.

Date: April 19th, 2024, 15:00 (Warsaw time)
