Since 1996, and with generous funding from the European Commission’s DG-EMPL, EUROMOD has been developed as a tax-benefit microsimulation model for the European Union, growing in size as the bloc itself has grown, with coverage extending to all member states. Such has been the tool’s success in attracting both academic and policy users that responsibility for the maintenance and update of the EU model will, at the end of 2020, be taken over by the European Commission via a collaboration between the Joint Research Centre (JRC-Seville) and Eurostat, thus securing the model’s longevity. But EUROMOD is no longer just a platform for modelling the impacts of fiscal policy in the EU and its member states. EUROMOD’s flexibility, both of approach and software, means that it can be adapted to shortcut the process of building tax-benefit models with potentially comparable outputs for any country or region. In recent years, then, the EUROMOD platform has provided the technical infrastructure behind a brand new set of tax-benefit microsimulation models, expanding beyond Europe into the Global South. As part of the ongoing SOUTHMOD project funded by UNU-WIDER, EUROMOD provides the “engine” that powers microsimulation models for seven countries: Ghana, Ethiopia, Zambia, Tanzania, Mozambique, Ecuador and Vietnam. The same project has also seen updates to existing EUROMOD-powered models for South Africa (SAMOD) and Namibia (NAMOD), managed by our long-term collaborators, Southern African Social Policy Research Insights (SASPRI).
