Abstract
ABSTRACT This study analyses whether higher efficiency performance of Ecuadorian hospitals attracts larger inflows of interregional patients to a given hospital and assesses the existence of spatial dependence in the patient migration network. We develop an innovative two-stage approach. In the first stage, we use conditional order-m estimations to obtain robust hospital efficiency. In the second stage, we apply a spatial Durbin interaction model to estimate the effect of hospital efficiency on patient migration flows and disentangle the spillover effects. We identify the positive effect of specialized hospitals’ efficiency in attracting patients from other regions alongside spillover effects in the migration dyad.
