Maria Noel Pi Alperin of the Luxembourgian SHARE team at the Luxembourg Institute of Socio-Economic Research (LISER) is currently working with the Central Bank of Luxembourg and the Luxembourg Institute of Health on a joint project. The aim of the cooperation is to compute the country’s long-term projections of the healthcare and long-term care expenditures. In particular, health expenditure are calculated by linking individual conditions to the use of medical resources (e.g. specific drug treatments, probability of surgical interventions, hospitalization). With the help of SHARE data, the researchers developed a new microsimulation model, which allows accounting for the effect of policy changes and different assumptions about the ageing process. Some of the project’s results have helped the Central Bank of Luxembourg to give advice on the Law project about the Public expenditures for the financial year 2019 and the multiannual programs for the period 2018-2022 and the Law project about the Public expenditures for the financial year 2020 and the multiannual programs for the period 2019-2023. Another paper will focus on the costs of dementia.
