Andres Mena

I am a PhD economist with expertise in causal inference and econometrics. I develop statistical solutions to inform large-scale decision-making.

As a member of Amazon’s Prime Economics team, I develop causal inference tools and economic models to shape business decisions impacting over 200 million customers worldwide. Previously, I worked on pricing at Microsoft and supply-chain experimentation, customer analytics, and infrastructure investment at Amazon.

I also co-founded LAPDE, a public policy laboratory at the Universidad Nacional de Tucumán connecting applied research with equitable economic development.
