Since the early 90's, the Federal Planning Bureau assesses the sustainability of pensions in Belgium. Since a couple of years, it uses a dynamic microsimulation model, MIDAS_BE, to assess the development of the adequacy of pensions. This working paper illustrates the possibilities generated by...

This paper develops a dynamic microsimulation model with static ageing to assess the consequences of the assumptions and hypothesis of the Federal Planning Bureau on the prospective adequacy of pensions. A less technical and shorter version of this text was published as Gijs Dekkers, 2000,...

Possible future trends in the development of pension adequacy are usually simulated using dynamic microsimulation models. These models are very complex and include many different processes. This, and the many individual interactions, makes it difficult to see which procedures and relations...

This presentation discusses how such integrated approach using shared demographic and macroeconomic assumptions has been developed in Belgium. It describes the dynamic microsimulation model MIDAS, highlighting how it aligns to the simulation results of the semi-aggregate model MALTESE. The...

A dynamic model with cross-sectional dynamic ageing builds up complete synthetic life histories for each individual, starting from a survey dataset or an administrative dataset. Many of these datasets include weights. This is a problem for dynamic microsimulation models, since the most obvious...
