Several studies show cases where the Samuelson rule holds, or where the marginal cost of public funds (MCF) equals one within optimized tax systems. The conditions for the original Samuelson rule to hold in these studies are quite restrictive, and MCF measures employed are not consistent with...

This paper studies tax policy interaction among local governments for both mobile and immobile tax bases. We exploit exogenous changes in the local tax setting of German municipalities due to participation in state debt reduction programs to learn about the size, scope and nature of strategic...

There still seems to be some confusion about the consequences of normalisations in the optimal taxation literature. We claim that:1) Normalisations do not matter for the real solution of optimal taxation problem.2) Normalisations do matter for good characterisations of the solutions to optimal...

This paper extends the Mirrlees (1971) model of optimal income redistribution with optimal corrective taxes to internalize consumption externalities. It is demonstrated that the optimal second-best tax on an externality-generating good should not be corrected for the marginal cost of public...

Belgium has seen major changes in its tax-benefit system over the past twenty years. These changes have, to a large extent, co-determined the evolution of disposable incomes of Belgian households on one hand, and their incentives to work on the other. In this paper we assess equity and...

Recent estimates of the marginal cost of public funds differ substantially. Some studies argue that the efficiency cost of taxation counter the welfare gain connected to redistribution of income. Hence, the efficiency cost of taxation should not be included as a cost of public goods provision....

The marginal cost of public funds is the equilibrium price at the intersection of the appropriately-defined demand curve for and the supply curve of public expenditure. In a world with identical people and with no excess burden of taxation, that price would have to be 1. Otherwise the median...

Disputes over the marginal cost of public funds may be about its magnitude in any given time and place or about its role in cost-benefit analysis. This paper is about the latter. The Samuelson rule was devised for an omnipotent, omniscient and benevolent government. This paper is about how the...
