To promote transparency and provide information, the Federal Planning Bureau regularly publishes the methods and results of its works. The publications are organised in different series, such as Outlooks, Working Papers and Planning Papers. Some reports can be consulted here, along with the Short Term Update newsletters that were published until 2015. You can search our publications by theme, publication type, author and year.
In Belgium, the Law on Fiscal and Social Greening of Mobility of 25 November 2021 eliminates corporate tax deductibility for all company cars except those with zero CO2 emissions. The main effect of the tax reform is an accelerated electrification of the company car fleet and an accelerated decline in CO2 emissions. Compared to the no-reform scenario, the reform leads to an increase in net tax revenues of about 1 billion euro on an annual basis.

A policy mix of “stick” measures (generalised distance based road charge) and “carrot” measures (supporting carpooling) could induce an increase in the occupation rate of cars in Belgium from 1.44 to 1.50. This relatively modest increase can be explained by the relatively small share of trips for which an increase in the occupation rate is a realistic option, and by the inconveniences linked to the organisation of carpooling. Nevertheless, this policy mix can induce a notable improvement in the traffic situation during the peak periods in the regions that currently suffer the most from congestion.

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.

Two Working Papers on the macroeconomic impact of network industry reform have been published. The first is a detailed report in Dutch, the second a summary paper in English. The analysis builds on a simulation by FPB’s macroeconometric model HERMES, and a simulation by IMF’s general equilibrium model GEM. Although both simulations were based on the same exogenous input, they gave significantly different outcomes. This sheds light on the applicability of different modelling approaches to an issue at hand.

In network industries the market reform that is being pursued by national and supranational authorities should lead to an improvement of efficiency, which spills over into a beneficial macroeconomic impact. This paper presents two alternative simulations of the potential impact in Belgium. These simulations give very different outcomes, but are still complementary. A macroeconometric approach seems to be more realistic in the short and mid term because it has been built up from observed behavioural relationships. A general-equilibrium approach gives rise to drawing some lessons about the conditions that make the impact more pronounced in the long term.

The aim of this working paper is to carry out a descriptive analysis of the geographical concentration of the manufacturing sector in Belgium, from which geographical agglomeration of sectors of activity is analyzed at a fine industrial level, i.e. NACEBEL 4-digit industries.
