This table presents the results from Eq. (1) and estimates provider price responses to the CalPERS reference pricing program. The odd-numbered columns restrict the sample to ASC providers and the even-numbered columns restrict the sample to HOPD providers. The dependent variable in all columns is ln(price_ijtk) and each regression is estimated using OLS. Controls for month, patient age, gender, Charlson comorbidity score, indicators for 17 chronic conditions, and patient HRR fixed effects are included but not reported. Robust standard errors clustered at the Hospital Service Area level are in parentheses.
