The Blinder-Oaxaca decomposition technique is widely used to identify and quantify the separate contributions of differences in measurable characteristics to group differences in an outcome of interest. The use of a linear probability model and the standard BlinderOaxaca decomposition, however, can provide misleading estimates when the dependent variable is binary, especially when group differe...

There is substantial evidence that on average, urban children have better health outcomes than rural children. This paper investigates the underlying factors that account for the regional disparities in child malnutrition in three Arab countries, namely; Egypt, Jordan, and Yemen. We use data on a nationally representative sample from the most recent rounds of the Demographic and Health Survey. ...

Unexplained Gaps and Oaxaca-Blinder Decompositions We analyze four methods to measure unexplained gaps in mean outcomes: three decompositions based on the seminal work of Oaxaca (1973) and Blinder (1973) and an approach involving a seemingly naïve regression that includes a group indicator variable. Our analysis yields two principal findings. We show that the coefficient on a group indicator va...

Cameroon’s informal labour market largely harbours female workers, engaged mainly in low-productivity and low-paying jobs. We investigate the sticky floor glass ceiling phenomena as a whole across its segments. use 2010 Cameroon survey, employing recentred influence function blending Oaxaca-Ransom Neuman-Oaxaca decomposition methods. The resulting framework enables us to account for selectivity...

We analyze wage growth and changes in wage inequality in eleven European countries between 1994 and 2001. The data base used throughout is the User Data Base (UDB) of the European Community Household Panel (ECHP). The decomposition analysis is carried out independently for both genders. Following Juhn, Murphy and Pierce (1991 and 1993) we split the current wage into components to isolate the fo...

OBJECTIVE This study examines the extent that older persons experience patterns of health service use that vary by race. METHODS Using the 1989 NLTCS database, researchers estimate ten binomial logistic regressions of community medical service use by disabled White and Black older persons. Chow tests and Oaxaca decomposition analysis inform why racial differences continue to exist, although m...

Using firm level data from eight Sub-Saharan Africa countries we examine credit constraint differentials between male and female manufacturing entrepreneurs. Enterprises owned by female entrepreneurs are less likely to be credit constrained compared to their male counterparts. The magnitude of this credit constraint gap varies with constraint and ownership definitions but the direction of the g...

This is a preliminary study of the diversity of the Flea Beetles (Alticinae) of the Mexican state of Oaxaca based on fieldwork by the author in 1991, 1997, and 2010, the literature, and specimens in several institutional collections. The number of genera and species for Mexico as well as for Oaxaca increased significantly from previous studies. There are now 625 species in 90 genera recorded fr...
