Are consumption taxes really regressive?
Nope. Once the informal sector is taken into account, consumption taxes can actually be progressive!
See this important study by
@pierrebachas
@LucieGadenne
& Anders Jensen for details on the methods & data 👇🏻
``Can indirect taxes help reduce inequality in developing countries?
Accounting for the informal sector makes consumption taxes progressive, but widespread tax exemptions on necessity goods (food) regressive.''
