Reflections on Heckman and Pinto’s “Causal Analysis After Haavelmo”
A recent article by Heckman and Pinto (HP) (link: http://www.nber.org/papers/w19453.pdf) discusses the do-calculus as a formal operationalization of Haavelmo’s approach to policy intervention. HP replace the do-operator with an equivalent operator, called “fix,” which simulates a Fisherian experiment with randomized “do”. They advocate the use of “fix,” discover limitations in “do,” and inform readers that those limitations disappear in “the Haavelmo approach.”
I examine the logic of HP’s paper, its factual basis, and its impact on econometric research and education (link: http://ftp.cs.ucla.edu/pub/stat_ser/r420.pdf).
