I am an Associate Professor at the Instituto Tecnológico Autónomo de México (ITAM) and a researcher at its Centro de Investigación Económica (CIE). I work in macroeconomics and labor economics, on the aggregate and distributional effects of changes to taxes and transfers in developed and middle-income countries. More recently, I have been studying how tariffs propagate through global production networks, and what Roman coinage reveals about money and inflation.
This is where I post my research, teaching materials and, sometimes, pictures of my dogs Aristotle, Ragnar and Hermes.
