Propensity score matching provides an estimate of the effect of a 'treatment' variable on an outcome variable that is … largely free of bias arising from an association between treatment status and observable variables. However, matching methods … undermine the conclusions about causal effects from a matching analysis. Instrumental variables (IV) estimation provides an …
