Tax Competition Reconsidered

Abstract

In a classic model of tax competition, this paper shows that the level of public good provision and taxation in a decentralized equilibrium can be efficient or inefficient with either too much or too little public good provision. The key is whether there exists a unilateral incentive to deviate from the efficient state and, if so, whether this entails raising or lowering taxes. A priori, there is no reason to suppose the incentive is in either one direction or the other.
