The State and Tax Competition

Governments increasingly use their fiscal policy to attract mobile capital from abroad. This tax competition puts a strain on the international fiscal system by undermining the capacity of states to make autonomous fiscal choices and by exacerbating inequalities. The existing regulatory framework is not able to address these challenges. Yet, what considerations should guide our efforts for reform? This chapter argues that a first necessary step consists in understanding the principles that justify the state as the principal locus of fiscal control in the first place. Building on an account of the legitimacy of the state and its fiscal powers, the chapter shows how tax competition is in tension with the principal objectives this account assigns to the state. It then outlines a normative response to tax competition that relies on both reforming jurisdictional rules and redistribution between states.
