Economization & Ecologization / The Hidden Barter Economy

Part 1 Economization, Ecologization, and Care (4-5pm)

The first talk discusses ecologization as a care-centered reorientation of economic activity. Reflecting on a long collaboration with Michel Callon and Donald Mackenzie, I argue that rather than treating the economy as a fixed domain organized around production and exchange, we can focus on shifting strategic orientations that foreground the maintenance and sustainability of heterogeneous collectives of humans and non-humans.

Part 2 No Money, No Problem: The Hidden Barter Economy of Digital Platforms (5-6pm)
Economic theory declared barter a relic. Platform capitalism proved it wrong. This talk argues that beneath every search query, every scroll, and every click lies a sophisticated system of non-monetary exchange that both mainstream and critical accounts of economies have largely left untheorized. Drawing on empirical research into Google Search and digital video platforms,this talk examines how platforms coordinate the acquisition of attention, relevance signals, and behavioral traces from users without recourse to price or payment. These are not incidental or residual transactions. They are structured, repeatable, and infrastructurally stabilized forms of barter, operating at a scale that classical theory deemed impossible for non-monetary exchange. To theorize this coordination, the talk develops the concept of the dyad: a coupled pair of heterogeneous valuables held by two positions whose exchange is organized through interfaces, metrics, algorithmic feedback loops, and database architectures rather than through price signals. The dyad allows us to see what transactional and extractivist frameworks alike tend to obscure, that platform participation is not free use, but draws on an ongoing, asymmetric, and infrastructurally governed barter relation. Far from vanishing with the rise of markets, barter has been quietly rebuilt at the core of digital capitalism.
