Johannes Haushofer is a development economist and Professor of Economics at the National University of Singapore and Stockholm University. One of his main research interests is the reduction of poverty in the Global South. At the same time, he is also active as a practitioner in this field: in 2021, he founded the organisation Malengo, which enables school graduates from low-income countries to study in Europe. The impact of their support is being scientifically analysed by an independent research team. In this interview, Johannes Haushofer explains how he came to investigate the effects of educational migration, how exactly the Malengo project works and which research questions are at the centre of the investigation into its impact.
