I have two new working papers on how market participants react to text-based information. Both fine-tune Llama 3.1 8B (an open LLM trained on data up to 2023) to predict financial variables, and we evaluate the model on data from 2024–2025 to ensure that the analysis is out-of-sample. (1/3)

I recently realised that using proprietary LLMs like OpenAIs GPT models to analyse text data is a disaster for replication. OpenAI discontinues its models after 2-3 years, after which replication will be impossible. This is less than what it takes to publish a paper. (1/2) #EconSky
