Globalisation squeezes the public sector—is it so obvious?

Abstract

It is widely perceived that globalization squeezes public sector activities by making taxation more costly. This is attributed to increased factor mobility and to a more elastic labour demand due to improved scope for relocation of production, and thus employment across countries. We argue that this consensus view overlooks that gains from trade unambiguously work to lower the marginal costs of public funds. Moreover, we argue that a more elastic labour demand may actually reduce the marginal costs of labour income taxation and that globalization may actually reduce the labour demand elasticity.
