Monitoring for Waste: Evidence from Medicare Audits
Abstract
This paper examines the tradeoffs of monitoring for wasteful public spending. By penalizing unnecessary spending, monitoring improves the quality of public expenditure and incentivizes firms to invest in compliance technology. I study a large Medicare program that monitored for unnecessary healthcare spending and consider its effect on government savings, provider behavior, and patient health. Every dollar Medicare spent on monitoring generated $24-29 in government savings. The majority of savings stem from the deterrence of future care, rather than reclaimed payments from prior care. I do not find evidence that the health of the marginal patient is harmed, indicating that monitoring primarily deters low-value care. Monitoring does increase provider administrative costs, but these costs are mostly incurred upfront and include investments in technology to assess the medical necessity of care.
