This paper analyses the impact of both the nature of regional public spending and the federal government’s fiscal tools on the softness of the regional budget constraint and the regional provision of public good. We show that i) whatever the nature of regional public spending, the regional budget constraint is harder when the federal government can no longer manipulate its lump sum tax and ii) under the assumption that the federal government can no longer manipulate its lump sum tax, the federal bailout is lower when the region provides a public input rather than a public good but the regional budget constraint can be either softer or harder.
