2015) and global integration and local distinctions (Smets et al., 2015). This mounting phenomenon motivates an expanding body of research seeking to understand the nature, responses and implications of competing demands in organization. As one lens to explore these competing demands, institutional theory highlights divergent pressures from field level actors and investigates organizational and individual approaches to avoid, resolve or negotiate these tensions (Greenwood et al., 2011). Paradox theory offers another lens. Paradoxes are "persistent contradictions between interdependent elements" (Schad et al., 2016). This lens depicts tensions as inherent within organizational systems and seeks approaches to embrace their persistent nature. Deriving from distinct origins with different underlying assumptions, these lenses developed mainly independent of one another with few papers drawing from both (for exceptions see Jay, 2013; Battilana et al., 2014). Yet, together, the insight from these lenses can complement one another, generating richer and more diverse theorizing about competing demands and environmental complexity. In this essay, we seek to advance research on competing demands, tensions and complexity by comparing and contrasting institutional theory and paradox theory. We identify divergent assumptions, surface complementary understandings, and generate gaps for future research. We hope these reflections can inspire scholars to integrate ideas across theoretical traditions to result in more rich and diverse
