Pedro Sant'anna

Pedro H.C. Sant'Anna is an associate professor of economics at Emory University. His areas of research primarily concern difference in differences and other quasi-experimental methods used for causal inference.

Education and career In 2009, Sant'Anna received his bachelor's degree in economics from Ibmec, a university in Brazil.

Research Sant'Anna's research spans multiple areas of econometrics. Along with Brantly Callaway, Sant'Anna developed a variation of difference in differences intended to work with multiple time periods, conditioning on observed covariates, and treatment being implemented in different time periods. This paper also includes a discussion of how the Callaway-Sant'Anna estimator finds different results than a two-way fixed effects model of minimum wage policies on teen employment.

Coding Sant'Anna has developed packages for R, including the did package, which implements the Callaway-Sant'Anna estimator for difference-in-difference models. Another of his packages is DRDID, which implements a doubly-robust difference-in-differences estimator that he developed together with Jun Zhao.
