Factor decomposition of cross-country income inequality with interaction effects


  • Bruno Bracalente
  • Cristiano Perugini


In this paper we propose a decomposition of the Theil measures of per capita income inequality which accounts for interaction effects between its multiplicative factors. Our theoretical findings, supported by an empirical application referring to EU-25 countries, suggest that neglecting these effects may strongly bias the relative importance of some factors, with consequent misleading policy implications.
