This paper considers more major structural reforms which could address such problems in a systematic manner, and allow the implementation of a designed set of effective tax rates (ETRs) for social security clients and taxpayers.

This paper investigates the distributional and efficiency implications of a tax-mix change involving a reduction in personal income taxation financed by a board based consumption tax.
