Notes: robust standard errors corrected for within-catchment-area correlation in the error term are reported in parentheses (based on original catchment area designations). All regressions include year, primary diagnosis code, hospital and zip-code fixed effects and controls for patient age (dummies), sex, Charlson comorbidity and paygrade (dummies). MTF and Active-Duty-Patient X MTF are instrumented by a series of dummy variables capturing different distance bins between a patient’s residence and the closest MTF along with the interaction between such dummies and the active-duty-patient dummy. The coefficient of the MTF indicator is dropped due to the inclusion of provider fixed effects.
