This statistical method decomposes the difference in the means of outcome variables across two groups into a part that is due to cross-group differences in explanatory variables and a part that is due to differences in group-specific coefficients.For illustrative purposes, consider the example given on p. 473 of Jann (2008).However, instead of the difference and coefficients noted, let's assume the difference and coefficients were the following:This paper introduces the Blinder-Oaxaca decomposition method to be applied in explaining inequality in health outcome across any two groups. In order to understand every aspect of the inequality, multiple regression model can be used in a way to decompose the inequality into contributing factors.The Blinder-Oaxaca decomposition technique is typically applied to gender or racial earnings gaps with the goal of determining the percent of the gap that can be attributed to differences in attributes between groups and to labor market discrimination. We apply this technique to the racial gap in achievement tests with the goal of measuring the relative racial bias of these tests. The Armed ...Ben Jann, 2008.

This method was originally developed for labour economics, to decompose average wage differences among genders or races into endowment effects , which denote distributions of individual attributes, and residual effects which ...Since then, the Oaxaca-Blinder decomposition has been one of the most widely used models for understanding what may be attributed to observable and non-observable characteristics between two groups. A simplified version of their model decomposes intergroup differences in two parts. The decomposition aims to understand what part of the ...We propose to estimate the Blinder-Oaxaca decomposition by a single-equation model augmented with interactions between the group membership and other predictors. The relative importance of predictors on the discriminatory wage gap is examined by the interaction coefficients, which may lead to very different conclusions than the usual percentage ...Linden Consulting Group, LLC. Let me update my previous response and add some detail: Stata Journal 8 (4):480--492 introduces the Blinder-Oaxaca decomposition for nonlinear regression models ...The Blinder-Oaxaca decomposition (BOD) is a popular method for studying the contributions of explanatory factors to social inequality. The results have often been given causal interpretations. While recent work and this article both show that some types of BOD are equivalent to a counterfactual-based treatment effect/selection bias ...The decomposition results indicate only that there are different components which increase and decrease the outcome gap at the same time. Furthermore, the weighting of these components matters for the interpretation, as indicated by the difference between Omega=1 and Omega=0. So you might want to run the decomposition with the option "omega ...ABSTRACT. Does regional decentralization threaten the commitment to regional equality in government outcomes and outputs? We attempt to shed a light on this question by drawing on unique evidence from the largest European unitary states to have engaged in countrywide health system decentralization: Italy and Spain.The Blinder-Oaxaca decomposition technique is widely used to identify and quantify the separate contributions of group differences in measurable characteristics, such as education, experience, marital status, and geographical differences to racial and gender gaps in outcomes.

Since the seminal works by Oaxaca (1973) and Blinder (1973), the Oaxaca-Blinder (hereafter, OB) decomposition has been widely used in empirical economic analyses to investigate differences in mean outcomes between groups (see, For tin, Lemieux and Firpo, 2011, for an overview). The OB decompositions are typically obtained as ...Panel data methods were combined with an Oaxaca decomposition to investigate the gender differences in resource endowment and return to endowment driving this gap. Although men have greater access to inputs, input use is so low and inverse returns to plot size so strong in Uganda that smaller female-managed plots have a net endowment …Furthermore, we used the Blinder-Oaxaca decomposition analysis to identify municipal-level exposure and vulnerability factors that contributed to ethnic disparities and how the contributions of these factors changed across the three initial waves of infection. Two clear results emerged. First, in NJ, the COVID-19 infection risk ...The Blinder-Oaxaca decomposition has been a valuable tool for the analysis of wage gaps since its con-ception in the early 1970s (Blinder, 1973 and Oaxaca, 1973).

Finally, the third command, oaxaca_rif, is a wrapper around oaxaca (Jann 2008) that can be used to implement standard and reweighted OB decompositions (see Fortin, Lemieux, and Firpo [2011] and Firpo, Fortin, and Lemieux [2018]). The rest of this paper is structured as follows.For the reweighted standard decomposition, oaxaca_rif first fits the probability model, then estimates the reweighting factor ω(X), and then obtains the RIFs for the three scenarios.

The original Blinder—Oaxaca decomposition used b w0 instead of the average coefficient, (b w0 + b m0)/2, assuming b w0 is a true market price and b m0 is a result of discrimination, thus group m will receive b w0 in the absence of discrimination. This assumption overlooks that b w0 itself is an endogenous product of market discrimination.
