In an age of climate emergency and social divide, we investigate how the use of design methods in Market Studies can drive positive, real-world change through the development of moral markets. As universities catalyse technological innovation using responsible research and innovation approaches that bring in multiple stakeholders, new opportunities to simultaneously make moral markets have opened-up. Viewing moral markets as dynamic sociomaterial assemblages that seek to deliver value for people and the planet, but are always in the making, implies that Market Studies researchers can engaged in their transformation. Through a focus on design methods, we see how market-studies researcher actively engage in market interventions and transformation activities, and how this activism is shaping our understanding of the future. We draw on a pragmatist perspective on design inquiry, outlining different elements and devices of co-design methodology, and provide an example of its use in Market Studies. We conclude that, in a research environment that demands real-world impact, design methods may come to challenge and complement traditional research practices due to their ability to transform and create new worlds.
