Dear colleagues, We invite your submissions to an Open Panel dedicated to “Markets as Data” at the Society for Social Studies of Science (4S) annual meeting which will be held in Toronto (and online), 6-9 October 2021. STS scholars have long been interested in the diverse devices that equip markets, from market infrastructures to mundane marketing tools such as shopping carts, knowledge devices, and measuring instruments. As markets are digitized, consumer records, scoring and targeting instruments, trading machines, and so on are key to how markets operate. Data act as a versatile, yet vital, apparatus for markets, playing crucial roles in the form of devices, valuation tools, infrastructures, and assets. This panel will explore these various facets of data, and how they help to bring markets into being. We welcome empirical and theoretical investigations of markets as data. First, with big data technologies, marketing knowledge is increasingly produced from the analysis of large databases that combine heterogeneous arrays of information on consumers, products, firms, and market operations. These data are then stabilized through metrics, dashboards and standards. How do these new “data objects” and knowledge devices reconfigure practices? Second, data streams are fueling automation or decision-making systems: matching algorithms, trade desks, recommendation engines, smart contracts, market screening mechanisms, dashboards. How does automation reconfigure firms’ practices in markets? Third, data are increasingly marketized themselves, harvested from public-facing services such as social media. How do markets for data impact “conventional” markets? Finally, data practices are increasingly subject to specific governance that is often the object of fierce contestation: from regulation such as GDPR in Europe, industry-level self-regulation and labelling processes, to local framing within firms. How does the governance of data, and its contestation shape markets and marketization practices?
