In an economic environment defined by precarious and gig-based labour contracts, academic research has been reimagined as a source of income for research participants. In addition, with the rise of online labour platforms, researchers have turned to online labour platforms as a solution to the increasing difficulty in recruitment of participants in research. This present context makes explicit the hidden labour that research participants have always done in the production of research outputs within academia. This paper develops a Marxist lens through which we can understand the material conditions of the circulation of capital through academia and the role of research participants in this mode of production. By developing this broad analytical framework for the academic mode of production, this paper further argues that our present economic epoch of the gig economy and specifically the use of digital labour platforms for academic research, has accelerated the subsumption of research participation as a source of income through the fragmentation of work and the gigification of everyday life.
