The effect of competition for mobile capital on local (jurisdictional) policy making is critical to the fiscal-environmental federalism literature. This existing body of literature, however, is deficient in examinations of how influential local policy levers, environmental standards and taxation, compare with fundamental capital location determinants like agglomeration forces. The purpose of this investigation is to broaden the agglomeration augmented interjurisdictional competition model to effectively compare local policy and agglomeration influences on capital flow. When jurisdictions do not have access to forms of taxation that allow for the efficiency of public goods provision, agglomeration forces notably impact fiscal policy weight. Herein, the magnitude of agglomeration directly effects the determination of the capital tax rate which in turn influences the provision of public goods. Subsequent inefficient public goods provision will distort the local choice of environmental standards. The capital tax must be complimented by 'benefit' taxation to finance efficient public expenditure. Interestingly, when public goods are provided efficiently, the capital tax doubles as a Pigovian remedy and a subsidy instrument depending, largely, on the strength of agglomeration forces.
