Abstract

The Winter 2021 issue of the International Journal of Microsimulation contains five articles. The first one, by Luke Archer, Nik Lomax and Bryan Tysinger, describes the English Future Elderly Model, an adaptation of the well-established Future Elderly Model (FEM) developed in the US to the English Longitudinal Study of Ageing (FEM plays a big part in the special issue of Health Economics on ageing, referenced below). The second article, by Santtu Tikka, Jussi Hakanen, Mirka Saarela and Juha Karvanen, is also a health microsimulation paper, where the authors describe a newly developed open source microsimulation structure in R. We then have another contribution by Finnish authors, introducing a new indicator for life course partitioning —a follow up on Salonen et al. (2020), also published in this journal. The fourth article, by Alice Richardson and co-authors, is another contribution to health microsimulation, where the authors estimate the impact of a proposed tax on sugar sweetened beverage in Australia across small areas. Finally, the paper by Cristina Cirillo, Lucia Imperioli and Marco Manzo introduces a new microsimulation model for indirect taxes in Italy.
