The PLANET Model : Methodological Report PLANET 4.0

PLANET is a model developed by the Belgian Federal PLANning Bureau that models the relationship between Economy and Transport. Its aim is to produce: (i) medium- and long-term projections of transport demand in Belgium, both for passenger and freight transport; (ii) simulations of the effects of transport policy measures; (iii) cost-benefit analyses of transport policy measures. This methodological report describes the main features of the PLANET model, and more specifically, the version 4.0 used for the transport outlook published in January 2019.

Perspectives de la demande de transport en Belgique à l’horizon 2040
Vooruitzichten van de transportvraag in België tegen 2040

Within the framework of a cooperation agreement between the Federal Planning Bureau and the Federal Public Service Mobility and Transport, the Federal Planning Bureau produces, every three years, long-term projections of transport demand in Belgium. This exercise is the fourth of its kind so far. It aims to make a projection of no change in policy, indicating general long-term trends and allowing elements on which transport policy should be based to be identified and the impact of transport policy measures to be studied.

Tax Expenditure and the Cost of Labour Taxation - An application to company car taxation

The goal of this paper is to estimate the efficiency cost of one additional euro of revenue through the personal income tax system, considering its simultaneous effects on the labour market and the transport market. More precisely, we seek to derive estimates of the Marginal Excess Burden of marginal personal income tax rates in Belgium considering the subsidization of company cars. We find that taking into account of welfare losses in the transport market adds 5-7 cents to the welfare cost of an additional euro of tax revenue, compared to models that consider only the effects on the labour market. The cost of raising the top marginal tax rate rises by 28% to 58% depending on the model assumptions. As an aside, we estimate tax expenditure on the transport sector via the personal income tax system to be 1.9 billion euro. We conclude that there is scope for welfare improving by base broadening and rate cutting. The framework is applied to analyse the merits of cash-for-car proposals.

Commuting subsidies in Belgium - Implementation in the PLANET model

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.

Drivers of wholesale electricity prices in a small, open economy - Some evidence from the nuclear restart in Belgium

In this paper, the impact of a nuclear downtime and subsequent restart on wholesale electricity prices on the Belgian power exchange is investigated by means of a dual methodology. First, publicly available market data is used to construct a stable statistical model that is deployed to examine the effect of nuclear power generation variations on market price outcomes. Quantifying this phenomenon, also called the merit-order effect, with the aid of econometric methods translates into an esti-mated price decrease of around 10 €/MWh for a nuclear capacity hike of 2.5 GW. The importance and impact of the openness of the Belgian market, that is, its strong reliance on cross-border energy exchanges is highlighted. Next to this empirical evidence, the optimisation tool Crystal Super Grid is used to assess the impact of the resumed availability of the nuclear reactors on several indicators characterising the Belgian and European power landscape. A positive effect on overall welfare, consumer surplus and CO₂ emissions can be noticed. As regards prices, this analysis confirms the negative merit-order effect which is calculated to equal, on average over a year, 3.8 €/MWh. Nevertheless, temporary hourly excesses of 30 €/MWh can occur. The paper then describes the possible causes of divergence between the two approaches.

Our findings have important policy implications as they demonstrate the need to take the downward influence of prolonged nuclear power generation on wholesale prices into consideration when revising the (timetable in the) nuclear phase-out law since it may have a delaying effect on the compulsory energy transition towards a low-carbon economy.

The fiscal treatment of company cars in Belgium: effects on car demand, travel behaviour and external costs

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.
