Professor Isabel Horta Correia of CATÓLICA-LISBON was quoted in an article by Kenneth Rogoff, who was chief economist of the IMF and is currently Professor of Economics and Public Policy at Harvard University in the main generalist newspapers in several countries.
Rogoff, who was chief economist of the IMF and is currently Professor of Economics and Public Policy at Harvard University, writes about The Benefits of a Progressive Consumption Tax, and cites an article published by Isabel Horta Correia on American Economic Review in 2010 that points out the effects of a transition from the current tax systems still heavily dependent on income taxation to an ideal system where the only tax would be on consumption or value added. In that paper Isabel Horta Correia proves how this structural change in the tax system, together with a fixed transfer to each household (which has recently appeared under various names, for example universal basic income) leads to a very significant gain in the economy being this gain relatively larger for poorer families. That is, the proposed transition increases efficiency and equality in the economy.
This quote is all the more important as it shows that this piece of research, more than 10 years old, is still extremely current and helping to launch the debate on US tax policy.
