Notes: Each column presents regression results from a generalized translog production function (year effects included but not reported), clustered at the hospital level. The dependent variable is one-year risk-adjusted survival. Column 1 presents coefficients without hospital-level fixed effects; Column 2 includes hospital-level fixed effects. Note that many of the Factor A and Factor B coefficients drop out of Column 2 because of hospital fixed effects. For sample description and variable definitions see the notes to table 6.
