The paper revisits regression-based inequality decomposition, derives further theoretical results on the factor shares and applies them in an empirical setting. Noting that the approach based on Shorrocks and Fields is not directly applicable to an important welfare-based inequality index,...

The paper revisits the regression-based inequality decomposition based on Shorrocks and Fields, derives further theoretical results on the factor shares and applies them in an empirical setting. First we derive the asymptotic distribution of inequality factor share estimators for obtaining their...
