We examine how substance use disorder (SUD) treatment providers respond to private health insurance expansions induced by state equal coverage ('parity') laws for SUD treatment. We use data on the near universe of specialty SUD treatment providers in the United States between 1997 and 2010 in an...

We study the incentives for hospitals to provide quality and expend cost-reducing effort when their budgets are soft, i.e., the payer may cover deficits or confiscate surpluses. The basic set up is a Hotelling model with two hospitals that differ in location and face demand uncertainty, where...

Using a spatial competition framework with three ex ante identical hospitals, we study the effects of a hospital merger on quality, price and welfare. The merging hospitals always reduce quality, but the non-merging hospital responds by reducing quality if prices are fixed and increasing quality...

Using a randomized field experiment, we show that health care specialists cream-skim patients by their expected profitability. In the German two-tier system, outpatient reimbursement rates for both public and private insurance are centrally determined but are more than twice as high for the...

We study theoretically and empirically how consumers in an individual private longterm health insurance market with front-loaded contracts respond to newly mandated portability requirements of their old-age provisions. To foster competition, effective 2009, the German legislature made the...

We ran a randomized field experiment to ascertain whether a costless manipulation of the informational content (restricted or enhanced information) and the framing (gain or loss framing) of the invitation letter to the breast cancer screening program in Messina, Italy, affects the take-up rate....

We measure one aspect of how access to emergency care through ambulance services changes for patients when a hospital closes. We empirically estimate the time needed to transport a patient to an emergency department in an ambulance in the period immediately after the hospital closes. We find...

We study whether and how physicians respond to financial incentives, making use of detailed register data on the health-care services provided to patients by general practitioners (GPs) in Norway over a six-year period (2006-11). To identify GPs' treatment responses, we exploit that...

This paper aims at shedding light on the social gradient by studying the relationship between socioeconomic status (SES) and provision of health care. Using administrative data on services provided by General Practitioners (GPs) in Norway over a five year period (2008-12), we analyse the...

We investigate the spillover effects of early-life medical treatments on the siblings of treated children. We use a regression discontinuity design that exploits changes in medical treatments across the very low birth weight (VLBW) cutoff. Using administrative data from Denmark, we first confirm...
