Non-Technical Summary: Past research has documented that mental health has a causal impact on physical health. This represents a local average treatment effect, but policymakers are primarily interested in mental health changes for the entire population, not just those exposed to an arbitrary exogenous shock. The need for reliable quantitative evidence presents a notable empirical challenge.
To fill this research void, we use a method developed by Altonji et al. (2005, 2011) and extended by Oster (2013, 2019) to estimate an unbiased treatment effect in the presence of unobservable selection. The method exploits information on selection along observable characteristics to reveal information on unobservable selection. After correcting for unobservable selection, we find that the mental health effect remains positive and significant. We also compare this bias-adjusted treatment effect with the IV estimate that uses deaths in the family to instrument mental health.
Our findings support the soundness of the instrumental-variable estimates in the present context. We conclude that researchers can have a good degree of confidence in using such estimates for policy formulation.
