Notes: Conditional logit model of choice of hospital for elective hip replacement patients treated between April 2010 and March 2013. Waiting time and quality metrics are lagged by one year. Willingness to travel (WTT) is the ratio of the coefficient on the quality variable to the marginal utility of distance evaluated at the average distance to the chosen hospital. Standard errors are clustered at GP practice level. Full results available on request.
