Measures political preferences and value alignment in generative AI systems.
Victor Rangel
Economist working on causal inference, public policy, political economy, and large language models.
I have a Bachelor's degree in Economics and I'm pursuing a Master's in Public Policy at Insper. I have professional and academic experience in data analysis, focusing on applied econometrics and machine learning.
I spend most of my days running acceptably biased OLS models and, additionally, I work as a science communicator and teach econometrics on my Instagram profile @econometriafacil (200,000+ followers). I also write the Econometria Fácil column at Folha de São Paulo.
