Using data from Colombia, we examine whether the informal sector achieves benefits from agglomeration economies as well as whether there are differences between the formal and informal sectors in terms of agglomeration returns. We find that agglomeration economies have a significantly positive effect on productivity in the informal sector: informal workers in denser areas will earn approximately 11% more than those in less dense areas.enghttps://v2.sherpa.ac.uk/id/publication/issn/0180-7307articleagglomeration economiesinformal sector2021-04-12Garcia, Gustavo A.10.25100/sye.v0i35.5647
