Marginal tax reform, externalities and income distribution.

The paper examines welfare improving and revenue neutral directions marginal policy reforms for an economy with nonidentical individuals and an externality that has a feedback effect on the consumption of taxed goods. It considers three types of policy instruments: the indirect taxes, the uniform poll transfer and public abatement. This extends the framework set up by Ahmad and Stern (1984), Bovenberg and de Mooij (1994) and Schöb (1996). The theoretical model is illustrated for a specific externality, namely congestion caused by peak car transport.

Capital-Intensive Projects Induce More Effort Than Labor-Intensive Projects

Central governments often subsidize capital spending by local governments, instead of subsidizing operating expenses or labor-intensive projects. This paper offers one explanation, focusing on the incentive effects for local officials--a local official can more easily shift the cost of optimizing a project to his successor on a labor-intensive project than on a capital-intensive project.Federalism; Capital subsidies; Transit subsidies

The political economy of fixed regional investment shares with an illustration for Belgian railway investments.

Many local public goods are allocated by federal governments using fixed regional shares: every region is entitled a fixed share of the total budget for a particular type of public good. This paper compares this fixed regional sharing rule with two alternative allocation rules: first best and common pool allocation. We find that the fixed regional sharing rule performs relatively well if the regional shares are reasonable. Legislative bargaining theory is used to study the determination of the fixed regional shares.

Urban Transport Pricing Reform With Two Levels Of Government

This paper analyses two challenges in the reform of urban transport pricing. The first challenge is the construction of an optimal package of urban transport pricing instruments assuming one benevolent government level that maximizes overall welfare. We examine the welfare gains from implementing in succession better parking prices, improved public transport prices and time varying tolling. It is found that parking and tolling are the most important elements of the optimal package and that the alternative policy instruments are sub-additive in their benefits. The second problem studied is the use of these pricing instruments by different government levels. We examine a case where an urban government controls parking fees and the regional government controls the tolling. Although both government levels have different objective functions, we find that the overall efficiency losses in the Nash and Stackelberg equilibria are limited.

Inefficiencies in regional commuting policy.

This paper discusses investments in transport infrastructure and incentives for commuting taxes in a multiregional setting. We study the horizontal and vertical interactions between governments. We identify incentives for strategic and tax exporting behavior that might lead to underinvestment in transport infrastructure. Furthermore, we show that the intensity of the strategic behavior is affected by geographic firm ownership structure, the number of labor-supplying regions and the revenue-sharing mechanism in the federation. A numerical example applies the insights on commuting in Belgium.

Regulating urban parking space : the choice between meter fees and time restrictions.

On-street urban parking spaces are typically regulated by either a meter fee or a time restriction. This paper shows that, when the off-street parking market is perfectly competitive, meter fees are more efficient than time restrictions. When on-street parking is free, albeit subject to a time restriction, too many drivers choose to engage in socially wasteful searching for on-street spaces. In contrast, with a meter fee, the relative benefit of parking on-street is reduced, and total search can be minimised. A linear meter fee structure is shown to be optimal. A simple policy prescription is also proposed. Set on-street meter fees equal to off-street parking fees. Finally, a simple numerical model calibrated to central London suggests that the use of optimal meter fees increases parking welfare vy around 5% over an optimal time restriction.

Environmental Tax Reform with Vertical Tax Externalities in a Federal State

The paper studies a regional environmental tax reform in a federal state. In a model with immobile labour, mobile capital and mobile polluting input in the production function, one region increases its pollution taxes and recycles the excess tax revenues by lowering either pre-existing distorting labour or capital taxes. This choice determines whether the non-environmental efficiency of the regional tax system improves or gets worse. Moreover, the regional tax reform changes the level of the federal budget through the vertical tax externality effect. We illustrate the magnitude of the different effects with simulations for a country with only 2 regions (Belgium) and a country with 50 regions (US).Tax Reform, Tax externality, Federalism, Tax Burden, Capital Mobility

Should Diesel Cars in Europe be discouraged ?

This paper examines the rationale for the different tax treatment of gasoline and diesel cars currently observed in Europe. First, we analyse possible justifications for a different tax treatment: pure tax revenue considerations, externality considerations and constraints on the tax instruments used for cars and trucks. Next, an applied general equilibrium model is used to assess the welfare effects of revenue neutral changes in the vehicle and fuel taxes on diesel and gasoline cars. The model integrates the effects on tax revenue, environmental externalities, road congestion, accidents and income distribution.

Automobile fuel efficiency policies with international innovation spillovers.

In this paper, we explore automobile fuel efficiency policies in the presence of two externalities i) a global environmental problem and ii) international innovation spillovers. Using a simple model with two regions, we show that both a fuel tax and a tax on vehicles based on their fuel economy rating are needed to decentralize the first best. We also show that if policies are not coordinated between regions, the resulting gas taxes will be set too low and each region will use the tax on fuel rating, to reduce the damage caused by foreign drivers. If standards are used instead of taxes, we find that spillovers may alleviate free-riding. Under some conditions, a strict standard in one region may favour the adoption of a strict standard in the other one.Environmental policy; Automobile; Fuel efficiency standard; Gasoline tax; Innovation spillovers;
