The principle of limited liability is one of the defining characteristics of modern corporate capitalism. It is also, we argue in this article, a powerful structural source of moral hazard. Engaging in a double conceptual genealogy, we investigate how the concepts of moral hazard and limited liability have evolved and diffused over time. We highlight two parallel but unconnected paths of construction, diffusion, moral contestation, and eventual institutionalization. We bring to the fore clear elective affinities between both concepts and their (...) respective evolution. Going one step further, we suggest that both concepts have come to be connected through time. In the context of contemporary capitalism, limited liability has to be understood, we argue, as a powerful structural source of moral hazard. In conclusion, we propose that this structural link between limited liability and moral hazard is an important explanatory factor of the systemic instability of contemporary capitalism and, as a consequence, of a pattern of recurrent crises that are regularly disrupting our economies and societies.
