This collected volume analyses labelling as a political and economic operation. It gathers contributions that focus on various domains, including the agri-food sector, the construction sector, eco-labelling, retail, health public policies and the energy sector, considering the use of labels for various objectives, such as providing legal and technical data on consumption products, certifying their quality, and indicating the approval of professional or political authorities. These practices are tied to both public and private interventions that make civic concerns visible and aim to govern them. The book considers labelling the economy as an operation that introduces political questions into the economic realm, while also importing economic modes of reasoning into governance interventions. In doing so, the book considers the sociotechnical apparatus on which any label relies as a nexus where economic and political considerations are brought together.
