We borrow the notion of field from institutional theory to think through how markets and their ‘outsides’–or at least one particular manifestation of an ‘outside’–stand in a dynamic and interactive relationship. We distinguish the field and the market in terms of issues versus exchange and identity versus position. We argue that the lack of clarity as to how fields and markets differ, relate, overlap, and are bounded, jeopardizes our ability to address important societal debates concerning the roles of markets within and across other areas of social life. It also hinders a consolidation of insights across different approaches to studying markets, even though researchers from different disciplines often address similar concerns. Key questions for which both conceptual and analytical clarity are essential include how markets and their ‘outsides’ (here: Fields) intersect; whether and how diverse sets of actors interact, work, and migrate between fields and markets; and what dynamics may be observable between field and market. We provide four illustrative examples of field/market relationships and a theoretical, methodological, and empirical research agenda for future research into markets and their ‘outsides’.
