In a recent contribution, H. Naito (1999) has shown that production efficiency may be violated in the optimum with non-linear income taxation. Using a slightly simpler framework, this paper complements Naito's analysis in showing that production efficiency does not hold in the optimum with (i)...

It is often argued that the optimal level of public good provision is below the first-best level as long as the government's expenditures have to be financed by distortionary taxes. I examine this hypothesis and show that it is correct in a representative consumer economy if (i) the public good...

Recently, it became customary to argue that environmental quality - like ordinary public consumption - is crowded out by distortionary taxation. We show that this hypothesis does not hold provided that the marginal revenue of the environmental tax is positive. In this case, under-provision of...

Due to the use of distortionary taxation, real-world economies should attain a lower level of public expenditures than one might suspect from the analysis of artificial models where lump-sum taxes are assumed to be available. The paper examines this popular hypothesis by means of the two-type...

In an analysis of a two-type income tax model with endogenous wages, this paper shows that production efficiency is violated in the optimum with (i) non-linear and (ii) linear income taxation if and only if a distortionary tax schedule is implemented. These findings complement earlier results of...

In this paper, a two-type, two-period model of optimum income taxation is investigated. I assume full commitment and that current income determines the agents' tax burden in each period. It is shown that such a tax system does not allow one to implement the optimal long-term tax contract and...

Due to the use of distortionary taxation, many believe that real-world economies should attain a lower level of public expenditures than one might suspect from the analysis of artificial models where lump-sum taxes are assumed to be available. The paper examines this popular hypothesis by means...

This paper deals with second-best pollution taxation by investigating allocations instead of the corresponding tax rates. Assuming certain restrictions on utility and that the marginal revenue from environmental taxation is positive, it is shown that environmental quality is higher in second...
