This report quantifies the marginal external cost of transport (congestion costs and environmental costs) using the Federal Planning Bureau’s PLANET model and compares this to the transport taxes levied. These indicators were not covered in the ‘Projections of transport demand in Belgium by 2040’, published in 2019 by the Federal Planning Bureau and the FPS Mobility and Transport. In that sense this report supplements this publication.
This paper seeks to quantify the cost of the most important inefficiencies in Belgian transport taxation. To this end we calculate the welfare gain of an ideal, optimal tax/subsidy system across the transport market as a whole (i.e. considering private road traffic in conjunction with public transport). We found the total welfare gain to be 2.3 billion euros, of which 1.3 billion are due to time gains of remaining road users. Our measure lies significantly above those found in the literature, since we consider the distortion cause by a wide range of subsidies.
This paper seeks to quantify the size and traffic effects of commuting subsidies in Belgium. To this end we implement the most recently available data on both the personal income tax treatment of commuting reimbursement and subsidies to rail commuters in the PLANET model. We find that subsidy rates by tend to differ strongly by mode and by type of reimbursement. Commuting by own car is generally subsidized at low levels, if it enjoys any subsidy at all. Commuting by company car, bike and public transport enjoy relatively high levels of subsidization. Policy simulations show the importance of commuting subsidies in steering the modal split. Both the exemptions for commuting reimbursements as well as subsidies for rail commuters moderately steer traffic away from private transport, while also lengthening the average commute.
This paper seeks to understand how the current tax subsidy for the ownership and use of employer-provided cars influence behaviour by its recipients. We first seek to clarify how it affects the choice about cars, i.e. the number of cars a household owns, their engine size and their value. Second, we study the impact of the subsidy on the propensity to use a car for commuting and the number of kilometres driven for commuting and for other, private purposes. The analysis has been made on the basis of the BELDAM survey, a rich dataset on mobility behaviour in Belgium.
This paper seeks to extend the PLANET model to allow for an endogenous influence of transport sector outcomes on the economy. To this end, we embed the PLANET data on freight and household transport for 2003 into a static CGE model of the Belgian economy. Households use transport for commuting and leisure transport, while production sectors use freight as an input. We allow for important feedback effects on generalized transport costs through congestion. To illustrate the model, we contrast the effects of a kilometre charge on freight only and a charge that targets household transport as well.
