On 21 January 2020, we have hosted a workshop on "Modelling migration and decisions". The aim of the workshop was to discuss, in an informal setting, some promising avenues of modelling migration and migrant decisions, with focus on four areas: migration data, decisions, model construction and analysis. For each area, we briefly shared our preliminary findings from the project, which were followed by an unfettered exchange of ideas and exploring areas for potential collaboration. The information note with the agenda for the workshop, as well as a more detailed report summarising the discussions, are available at the links below.
