This paper provides an overview of dynamic microsimulation modeling as well as its recent developments. It then discusses in detail a recent trend in microsimulation research, which uses alignment methodologies to simulate microsimulation models in conjunction with macro-economic models. The goal of this “top down-integrated approach” is to jointly assess the budgetary costs of demographic ageing and pension reform, as well as their consequences on the adequacy of pensions. This paper then discusses, also in detail, how such an 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. Finally, this paper suggests that the joint assessment using the joint application of two similar models might be useful to assess pension reform in the Japanese context.
