The widely used Oaxaca decomposition applies to linear models. Extending it to commonly used nonlinear models such as … duration models is not straightforward. This paper shows that the original decomposition that uses a linear model can also be … obtained by an application of the mean value theorem. By extension, this basis provides a means of obtaining a decomposition …
