The coefficient on the indicator variable Physician measures the effect of being a physician on a subject‘s place in the composite distribution of CCEI (columns 1–3), α (columns 4–6), and ρ (columns 7–9). The ρ parameter of purely selfless (α = 0) and purely selfish (α = 1) subjects, who always give nothing or everything, cannot be identified. In the regressions reported in columns 7–9, we thus omit purely selfless and purely selfish using a one-sided test at the 10% level. SEs are in parentheses, bootstrapped using 500 repetitions. ***P < 0.01 and ****P < 0.001.
