GDECOMP: Stata module to compute decomposition of outcome differentials after nonlinear models

Tamás Bartus

Statistical Software Components from Boston College Department of Economics

Abstract: gdecomp implements a generalized Blinder-Oaxaca decomposition which applies to categorical and count outcomes (and parallel to this, to nonlinear regression models). First, the estimation_command is estimated in the two groups of a groupvar. Then the observed difference in the dependent variable of estimation_command between the groups defined by groupvar is decomposed into three parts: (1) a part due to differences in endowments (labeled by E), (2) a part due to differences in marginal effects and finally (3) a part due to difference in baseline predictions or constants (labeled by U). The margeff package (also available from SSC) is required.
