• waiting time;
  • socioeconomic status;
  • administrative data


We investigate whether socioeconomic status, measured by income and education, affects waiting time when controls for severity and hospital-specific conditions are included. We also examine which aspects of the hospital supply (attachment to local hospital, traveling time, or choice of hospital) matter most for unequal treatment of different socioeconomic groups. The study uses administrative data from all elective inpatient and outpatient stays in somatic hospitals in Norway. The main results are that we find very little indication of discrimination with regard to income and education when both severity and aspects of hospital supply are controlled for. This result holds for both men and women. Copyright © 2013 John Wiley & Sons, Ltd.
