Bias among health care providers can lead to poor-quality care and poor health outcomes, and it can exacerbate disparities. We use a randomized controlled trial to evaluate an intervention to reduce family planning provider bias towards young women in 227 clinics in Tanzania, Burkina Faso, and...

In the context of a binary outcome, treatment, and instrument, Balke and Pearl (1993, 1997) establish that the monotonicity condition of Imbens and Angrist (1994) has no identifying power beyond instrument exogeneity for average potential outcomes and average treatment effects in the sense that...

The United States spends twice as much per person on pharmaceuticals as European countries, in large part because prices are much higher in the US. This fact has led policymakers to consider legislation for price controls. This paper assesses the effects of a US international reference pricing...

We examine whether loss of emergency department services is associated with county-level mortality rates in rural areas over the period 2005-2018. We use a propensity-weighted difference-in-difference approach, comparing counties that lost emergency department services to counties that retained...

We study the effect of price caps on the provision of costly effort by pharmaceutical firms using variation in drug discounts generated by a price regulation program that allows eligible hospitals to purchase outpatient drugs at steep discounts. These discounts directly affect drug...

This study examines "tunneling" practices through which health care providers covertly extract profit by making inflated payments for goods and services to commonly-owned related parties. While incentives to tunnel exist across sectors, health care providers may find it uniquely advantageous to...

Since the inception of Medicare Part D in 2006, mergers and acquisitions (M&A) and regulatory changes have led to increased concentration and reduced plan variety in the standalone prescription drug plan (PDP) portion of the market. We examine how this industry consolidation affects Medicare...

We study the effect of mandates requiring COVID-19 vaccination among healthcare industry workers adopted in 2021 in the United States. There are long-standing worker shortages in the U.S. healthcare industry, pre-dating the COVID-19 pandemic. The impact of COVID-19 vaccine mandates on shortages...

Technological innovation in medical services can improve health, but its ability to reach patients often depends on price signals for downstream providers, which can also be discordant across production inputs. We examine such a context when Medicare sharply revises facility fees--while holding...

I demonstrate that to achieve dynamic efficiency, the optimal share of total surplus that a social payer should transfer to an innovating industry for a current asset depends on the marginal product of investment and the share of profits invested by the industry on the current asset and not on...
