|November 2019||How Do Low-Income Enrollees in the Affordable Care Act Marketplaces Respond to Cost-Sharing?|
with , : w26430
The ACA requires insurers to provide cost-sharing reductions (CSRs) to low-income consumers on the marketplaces. We link 2013-2015 All-Payer Claims Data to 2004-2013 administrative hospital discharge data from Utah and exploit policy-driven differences in the value of CSRs that are solely determined by income. We find that enrollees with lower cost sharing have higher levels of health care spending, controlling for past health care use. We estimate the demand elasticity of total health care spending to be -0.10, but find larger elasticities for emergency room care, lifestyle drugs, and low-value care. We also find positive cross-price elasticities between outpatient and inpatient care.

with : w22338
The design of Medicare Part D causes most Medicare beneficiaries to receive fragmented health insurance, whereby prescription drugs and other medical care are covered by separate insurance plans. Fragmentation of insurance plans is potentially inefficient since separate insurers maximize profits over only one component of healthcare spending, despite many complementarities and substitutabilities between types of healthcare. Fragmentation of some plans but not others can also lead to market distortions due to differential adverse selection, as integrated plans may use drug formulary designs to induce enrollment by patients who are profitable under Parts A & B, while stand-alone drug plans have no such incentive. We study whether the design of insurance plans in Medicare Part D reflects thes...
