We analyze four methods to measure unexplained gaps in mean outcomes, three based on the decomposition methods of Oaxaca, 1973, Blinder, 1973 and one based on a pooled regression with a group indicator variable. Our analysis yields two principal findings. We show that, in the case of a single observable characteristic, the coefficient on the ...We conducted the twofold Blinder-Oaxaca decomposition in Stata 15 (Jann, 2008). The twofold decomposition method focuses on the characteristic effect and association effect while neglecting the simultaneous effect of differences in endowments and coefficients (Jann, 2008).
