This research investigates sharing as a consumption practice in Brazilian low-middle class urban families. Given this purpose, the study adopts the Consumption Culture Theory (CCT) interpretative perspective, using the extended family residing in the same household as the unit of analysis. Sharing is an everyday practice in the individuals lives in both public and private spheres. Within the households, artifacts such as the refrigerator and its contents are shared, as well as furniture, utensils, and physical spaces. Individuals share meals, entertainment, and domestic chores. Outside the home, public spaces, commercial spaces such as restaurants and cinemas, transportation, landscapes, and other aspects of the physical world are all shared. Sharing within families is a social phenomenon that, although it has always been a daily consumption practice, it has practically been absent from studies on Consumer Behavior and related areas. The theoretical framework is based on the Consumer Culture Theory, specifically on the process of extracting meaning from consumption. The study used an interpretative approach, based on in-depth interviews with different members of the extended families. It followed the abductive method of systematic combining, which is characterized by continuous comings and goings between the theory and the field. This study contributes to increase the knowledge on consumption practices in three main ways: i) by expanding the understanding of the phenomenon of sharing, better outlining its conceptual and thematic borders; ii) by studying the phenomenon in the context of the Brazilian extended family, as opposed to the American nuclear family; and iii) by identifying specificities of how the phenomenon manifests among low middle class urban families. New categories emerged from the study to describe sharing, as well as comparative elements between sharing and lending as consumption practices. The study proposes a conceptual framework for the different types of sharing.
