We fill the gap by examining care-coordination under integration. We exploit the fact that integration varies across MSAs and focus on PPO patients with employment-based moves between MSAs. We develop a mover-stayer model with heterogenous effects to examine whether vertically integrated practices treat patients differently, or whether they just treat different patients. Moving to a more integrated market causes an increase in care coordination indices. Specifically, moving to an area with more specialty care integration causes an increase in team referrals between primary and specialty care, less lab and imaging use, less out-of-network care, and reductions in spending. That is, systems are able to narrow the scope of specialty services overall, hence creating greater social efficiencies. Moving to a market with more integrated primary care causes an increase in preventive care, decreased inpatient use by women, but an increase in spending.

The causal analysis for volunteers, who represent over 70% of veterans, is novel in this literature that typically focuses on the compliers. Since the effect for volunteers is not point-identified, we employ sharp nonparametric bounds that rely on a mild mean weak monotonicity assumption. We examine a large array of health outcomes and behaviors, including mortality, up to 38 years after the end of the Vietnam War. We do not find consistent statistical evidence of detrimental health effects on compliers, in line with prior literature. For volunteers, however, we document that their estimated bounds show statistically significant detrimental health effects that appear around 10 years after the end of the conflict. As a group, veterans experience similar statistically significant detrimental health effects from military service.

We show how the increase in the frailty index can be derived from the feature of self-productivity of health deficits. We explore the robustness of the Gompertz decomposition across countries, sex, and over time and show how information about mortality rates can be used to infer the state of health of an age-structured population.
