Décomposition de l'inégalité de revenu par source : méthode des rangs et application au cas de Taiwan <BR> version anglaise : "Inequality Decomposition by factor Component: a "rank correlation" approach illustrated on the Taiwanese Case"

This paper systematises the method initiated by Burtless (1999) and provides a general framework for decomposing inequality by factor components, which has the double advantage over usual decomposition procedures to allow for a decomposition of income distribution changes and to distinguish between marginal distribution changes of income sources and changes in correlation between sources. An illustration is provided for Taiwan, which emphasises the great role played by changes in correlation between spouses' incomes.
