This paper estimates the causal effects of breastfeeding on early child development using exogenous variation in breastfeeding support policies across UK maternity hospitals. Based on data from the Millennium Cohort Study, we find that mothers giving birth in hospitals where such policies are...

Ambulance response time to emergency calls is a key indicator of a health system's efficiency although its impact on health is not precisely known. This causal relation is identified by exploiting rainfall at the time of the ambulance run as a shock to responsiveness. The elasticity of the...

Non-random sorting can bias observational measures of institutional quality and distort quality-based polices. I develop alternative quasi-experimental approaches to quality estimation that accommodate nonlinear causal effects, institutional specialization, and unobserved selection-on-gains. I...

Hospitals in Japan have complete autonomy in deciding whether to admit COVID-19 patients, similar to that of the US. Taking this into account, we estimated the effect of admitting COVID-19 patients on hospital profits, using instrumental variable (IV) regression. Using IVs related to government...

In 2010-2012 new outpatient service locations were established in poor Hungarian microregions. We exploit this quasi-experiment to estimate the extent of substitution between outpatient and inpatient care. Fixed-effects Poisson models on individual-level panel data for years 2008-2015 show that...

Aging-in-place policies substitute home care for nursing home admissions (NHA). They appear to be a win-win by keeping public spending in check and being in line with personal preferences, but have hitherto not been evaluated. We study the impact of NHA eligibility using Dutch administrative...

We assess the lifesaving effect of hospital proximity using data on fatality rates of road-traffic accidents. While most of the literature on this topic is based on changes in distance to the nearest hospital triggered by hospital closures and use OLS estimates, our identification comes from the...

We provide a new assessment of the effect of hospital proximity in an emergency situation exploiting the exogenous variation in the proximity to cities that are legally allowed to have a hospital based on their population size. Based on Italian municipal data, our instrumental variable results...

We exploit the 2016 Brexit referendum as a migration shock to evaluate the impact of reduced labour supply on the provision of hospital care. After the referendum, a sharp drop in the number of early-career new joiners from Europe resulted in a considerable decrease in the share of EU nurses in...
