Potential Outcomes and Graphical Models: Comments to Imbens (2020)
Date:
Invited comments, EIPE Seminar, Erasmus University Rotterdam, Netherlands
Comments delivered at a seminar with Nobel laureate Guido Imbens that I organised at EIPE. In response to Imbens (2020), I argue that the potential-outcomes and DAG frameworks are complementary: PO is best suited for developing particular causal methods, while graphical models are best suited for formulating and verifying causal assumptions.
