Codes of governance have mushroomed in contexts operating under a single, dominant institutional logic, such as publicly listed corporations. These codes act as institutional prescriptions that help spread best practices throughout industries. More recently, in some countries, specific codes have been developed for hybrid organizations that integrate multiple, conflicting institutional logics simultaneously, such as cooperative enterprises. Drawing on an extensive set of qualitative data, we ask how such institutional prescriptions may (fail to) address governance challenges in organizations with multiple, conflicting (...) institutional demands. In doing so, we extend current literature on governance of hybrid organizations, which has so far focused on individual and organizational levels, to include institutional-level strategies. While governance codes are often inspired by deontological ethics to solve issues in a single institutional logic, we find that governance codes for hybrid organizations should not prioritize a single institutional logic, nor follow a deontological approach to improving governance, but should, on a more pragmatist take, remain open to continuous learning.
