Conditional logit models of choice of practice. Choice sets are all practices within stated distance of LSOA centroid and, if there are more than 30 such, the 30 nearest to the LSOA centroid. Choice set for the models stratified by LSOA population growth is all practice within 10 km, and if there are more than 30 such, the 30 nearest to the LSOA centroid. All models have the same covariates and cubic distance specification as Table 2. The distance coefficient is ${\hat{β}}_{d} + 2 {\hat{β}}_{d^{2}} \bar{d} + 3 {\hat{β}}_{d^{3}} \bar{d^{2}}$ where $\bar{d}$ and $\bar{d^{2}}$ are computed as the mean of the LSOA centroid to practice distance and squared distance for the sample defined by the stated radius. MRS is the quality coefficient divided by the distance coefficient. Conditional logit models of choice of practice. All models have the same covariates as in Table 2. The distance coefficient is the derivative of the utility function evaluated using the estimated coefficients and the mean of the powers of LSOA to practice distance for the whole sample. Standard errors clustered at LSOA level are in parentheses. *p < 0.05, **p < 0.01, ***p < 0.001.
