This research investigates two features of the Affordable Care Act that especially affect young adults, the young adult-dependent coverage (YAD) mandate and the requirement to cover contraception (CM). Both mandates were first enacted at the state level but have been studied only in isolation. We estimate a wide range of models allowing these mandates to have joint effects on insurance coverage, health-care access, health outcomes and fertility. We provide new evidence that helps settle the mixed findings from past state-level YAD and CM research and suggests the two mandates may combine to improve the well-being of young adults.
