Medium-term projection for Belgium
of the at-risk-of-poverty and social
exclusion indicators based on EU-SILC
This project is
co-funded by
the
European Union
Presentation at the
OECD ELS Seminar Series

• Co-financed by the European Commission (VS/2015/0179)
and the Federal Public Service Social Security of Belgium
• nowcasting and medium-term forecasts (currently up to
2020) of indicators of poverty and social exclusion.
• Using aligned dynamic microsimulation, starting from the EU-
SILC 2014 cross-sectional dataset
• Take into account all more recent demographic and socio-
economic developments and projections
• The model is built using experience and technical modules
from the existing model MIDAS.
• Developed in LIAM2 (de Menten et al., 2014).

• The purpose of any microsimulation model is to impute
missing data
- Alternative realities
- Prospective scenarios
• Based on actual or synthetic micro-level datasets

• Microsimulation models are used to evaluate the effects of
policy changes at the level of the decision making units
rather than focusing on the aggregate information.
• Focus is on the distribution of the target values, rather
than on the means or the aggregates.
• Also, microsimulation can be used to discern “winners”
and “losers” of developments and/or policy measures.
• Estimates of aggregate outcomes can however still be
derived by summing up individual predictions.

• Indicators of poverty and inequality are important in the
European semester
“flash estimates” of these indicators published in 2017 and
2018 (income years 2016 and 2017)
Main method is microsimulation modelling, where the static
model EUROMOD is enhanced to adjustments in the micro-data
Population structure, employment and growth of the main income
components
16 countries (including BE) through static ageing at the household
level, using LFS
8 countries dynamic ageing of gross changes between non-, un-
and employment.
Updating all non-simulated incomes to the target year
Current Nowcasting models: Euromod

• Module for labour market state to month, allowing for
simultaneous occurrence of earnings and benefits.
• Correction for “residual taxes”
Mechanical simulations result in net incomes being too low, due
too
1) witholding tax being unequal to the final tax, and
2) the impact of tax evasion or ad-hoc reductions.
• Statistical versus mechanistic simulation of pension benefits
• Endogenous statistical modeling of SMD
• Endogenous SMD, LWI and AROP => AROPE
• Immigration and emigration

• Benefits: from unemployment, disability, unemployment
with company supplement, social assistance, family
allowances
• Pensions: retirement, survival, guaranteed income for the
elderly (GIE)
‐ Simulated only for new pensioners: retirement and survival
pensions are based on estimations using longitudinal EU-SILC (6
estimated equations); GIE obtained by means-test
All observed benefits and pensions are uprated and possibly
adjusted based on the assumptions and application of
regulations

• Dynamic ageing
• Alignment with macro-economic indicators produced by FPB
• Reproduces SILC structure for nowcasted datasets
• Easily updated to new waves of SILC
• Delivers predicted indicators of poverty and social inclusion
for the whole population but also (possibly) for particular
subgroups
• Additional analyses are possible thanks to accessibility to the
nowcasted data

• Some of the results are vulnerable to assumptions, modeling
approaches and the sensitivity of the indicators.
• The nature of the SILC data
• The work in some way is not finished, and will require
additional work

• The aim of Nowcasting model is to update the observed SILC
data to the present time and the near future and predict a
range of social indicators based on those simulated datasets
• Current version of the model is based on 2014 wave of SILC
and produces synthetic datasets up to 2020
• It works as consistent as possible with observations and
short-term projections through the semi-aggregate model
MALTESE
• It reproduces SILC structure (non-monetary variables from t,
while incomes and earnings from t-1)
