We compare healthcare spending in public and private Medicare using newly available claims data from Medicare Advantage (MA) insurers. MA insurer revenues are 30 percent higher than their healthcare spending. Healthcare spending is 25 percent lower for MA enrollees than for enrollees in...

We study a unique all-payer data set spanning 38 states to examine the differences in inpatient reimbursement rates paid by traditional Medicare (TM), Medicare Advantage (MA), Medicaid, and private (under-65) insurers, and the differences in negotiated rates across the 60 largest private...

Reforms introduced by the Affordable Care and Patient Protection Act (ACA) build new sources of coverage around employment-based health insurance. But what if firms find it cheaper to have their employees obtain insurance from these sources, even after accounting for penalties (for non-provision...
