Average Causal Effect Estimation Via Instrumental Variables: the No Simultaneous Heterogeneity Assumption
Average Causal Effect Estimation Via Instrumental Variables: the No Simultaneous Heterogeneity Assumption
Background: Instrumental variables (IVs) can be used to provide evidence as to whether a treatment has a causal effect on an outcome . Even if the instrument satisfies the three core IV assumptions of relevance, independence, and exclusion restriction, further assumptions are required to identify the average causal effect (ACE) …
