My research investigates how insurance status, reimbursement policies, and regulatory changes shape healthcare provision, the financial resilience of healthcare providers, and patient outcomes. My current work centers on:

Healthcare Utilization and Financial Incentives: I examine the dynamics of emergency medical services, particularly how policy shifts like Medicaid expansion and private equity investments in ambulance services influence financial outcomes and patient health. My research has uncovered how Medicare's reimbursement structures lead to moral hazard among both consumers and providers, intensifying ambulance usage and upcoding practices, with significant spillover effects on emergency departments.

Hospital Financial Strategy and Risk Management: I explore how hospitals adjust their investment decisions in response to changes in tail risk, assessing the implications for patient health. This includes how Medicaid expansion interacts with state-level charity care mandates, impacting hospital finances.

Insurance Market Dynamics and Policy Implications: My research on moral hazard extends to insurance markets, where I analyze how charity care policies influence insurance take-up (or “charity hazard”), and how moral hazard, compounded by subsidies and community rating, can mimic adverse selection, posing challenges to insurance market stability.
