Published	08/12/2024	topic: causal inferencewe often want to estimate the "effect" of a treatment. in the causal inf/econ framework, the quantity of interest is usually th…

Published	08/19/2024	Topic: Causal InferenceSuppose we have a backdoor path - a graph where C causes both A and B, but either A nor B cause anything. We condition on the c…

Published	08/19/2024	Topic: Causal InferenceWhat happens if we add controls that are good predictors only for the treatment? Should we add them?
