Abstract: This paper suggests a method of decomposing differences in inter-group
probabilities from a logit model and shows how it can be related to similar
decompositions derived from a Oaxaca-Blinder framework. In so doing, it offers a
solution to a problem, embedded within the Oaxaca-Blinder decomposition,
relating to the appropriate choice of common coefficient vectors with which to
evaluate the different attribute vectors. The decomposition method also shows
how pair-wise comparisons of groups might be conducted in the presence of more
than two groups, without discarding the information on groups excluded from the
comparison. The proposed method is applied to inter-group differences in
schooling participation in India and the results are compared with the
Oaxaca-Blinder method. The decomposition is applied specifically to inter-group
differences in the enrolment of boys at school in India.
