Nonlinearity in Dynamic Causal Effects: Making the Bad into the Good, and the Good into the Great?
arXiv:2504.01140
Abstract
This paper was prepared as a comment on "Dynamic Causal Effects in a Nonlinear World: the Good, the Bad, and the Ugly" by Michal Kolesár and Mikkel Plagborg-Møller. We make three comments, including a novel contribution to the literature, showing how a reasonable economic interpretation can potentially be restored for average-effect estimators with negative weights.
