Types are classified based on the coefficients estimated in individual-level, auxiliary regressions in which we model the amount given as a function of the differences in respondents’ initial gift card values. See SI Appendix, Materials and Methods for estimation details. We use the following coding rules: −0.25≤sensitivity < 0.25, nonequalizer; 0.25≤sensitivity <0.75, equalizer; all other values, other. N = 4, 966.
