Mario Diez Martínez

I am an economist interested in AI economics, macroeconomics, monetary policy, labour economics, and financial markets. I have worked in quantitative trading and market risk, so I still follow markets every day. When a question stays with me, I usually end up turning it into a paper, a dataset, or a piece of code.

I studied Economics at Universidad Complutense de Madrid and am now completing a Master's in Chinese Economy at Zhejiang University. I have spent the past year living and studying in China, which has given me a closer view of its economy, firms, policy institutions, and the distance that sometimes exists between a clean model and how things work.

I also spend a lot of time trying to make AI workflows genuinely useful for research. That means organising notes, working through data, keeping long projects moving, and checking the parts that should not be trusted. This site contains the academic work, personal projects, and technical experiments that are ready to show.
