Fiscal competition and public debt

This paper explores the implications of high indebtedness for strategic tax setting when capital markets are integrated. When public borrowing is constrained due to sovereign default or by a binding fiscal rule, a rise in a country's initial debt level lowers investment in public infrastructure and makes tax setting more aggressive in that jurisdiction, while the opposite occurs elsewhere. On net a jurisdiction with higher initial debt becomes a less attractive location. Our analysis is inspired by fiscal responses in severely hit countries after the economic and financial crisis which are consistent with the theoretical predictions. We find a similar pattern on the sub-national level using administrative data from the universe of German municipalities.
