Notes: This table reports the average share of antibiotic prescribing differences between clinics that is attributable to provider practice style differences, the coefficient of
. The term Δi denotes the difference in mean antibiotic prescribing between patient i’s assigned sets of physicians, and is estimated by
, the leave-one-out estimator of antibiotic prescribing based on untreated patients. The term Dit represents the post-treatment indicator. Standard errors are calculated using a bootstrap with 50 repetitions at the patient level. ***p < 0.01.
