The 1st SDMRG International Workshop is a joint initiative with the Graduate program in Political Economy of the University of Brasília, and
represents a unique opportunity to discuss the latest research on various aspects of this complex project. The event is naturally intended to foster diversity in the approach and in the methodology used to analyse processes of catching-up and falling-behind. Safety restrictions due to the COVID-19 have not allowed the development of a conference in a more standard format. The organising committee thanks all participants and interested colleagues for their support in making this Online initiative to be possible.
