Arguably, Judea Pearl is the most influential "Causality Specialist" of our time. (My term, not his!)
If you don't subscribe to his blog (Causal Analysis in Theory and Practice) and newsletter already, I'd suggest that you do so.
Judea also has several very informative video interviews that should be of interest to economists and econometricians. For example:
- Introduction to Causality - Part I
- Teaching Causality - Part I; Part II
