Federalism faces difficult challenges in the era of globalisation, since the latter has generated pressures for reform in economic and political organisations and thereby in inter-governmental relations of all developing countries as well. There are forces in inter-governmental relations pulling in opposite directions, some tending to centralise functions of second tier governments, such as of the states in India, and others moving to decentralise to tiers further down, citing "subsidiarity". Although, globalisation at one level has given some functional autonomy for efficiency gain and competition and to attract private capital, it has restricted the scope for independent sub-state level fiscal policy. The biggest challenge for federalism in the coming years would be to respect the plurality of identity of human beings.
