Taking place: Bolivians in Buenos Aires itinerant street markets. This article inquires into the growing importance of Bolivians in Buenos Aires itinerant street markets, since the beginning of the 1990s. It shows how street markets are spaces where sellers as well as work inspectors play a game between formal and informal, which is very funcional for both activities, better profits on one hand, clientelist control on the other hand. We explain how conjoncture's effects (in the 90s and after the 2001's crisis), as well as the relevance of the social networks and the habit of familial work, have reinforced the constitution of an ethnic market in Bolivian commercial street activities. This economy is heterogeneous, contains social hierarchies within the Bolivian group, but is also a place for ascendant careers. The Bolivian presence in these street market circulating over the City of Buenos Aires reveals how they took place in the public space of the city, next to the Argentinian merchants, and how their increasing role moderates the classic geography of their exclusion towards the margins of the capital.
