Adopting a Lakatosian perspective, this paper asks whether management accounting (MA) research using institutional theory can be described as a degenerative or progressive research program. Motivated by similar critical debates about the larger institutional research program in organization studies, I map the evolution of institutional research on MA with an eye to its theoretical contributions to the accounting literature as well as this larger research program. I conclude that this body of research has offered important, progressive extensions to the accounting literature and, to a lesser extent, the larger institutional research program. However, there is also evidence of many MA scholars using institutional theory in ways that produce degenerative tendencies. These degenerative tendencies are, in large part, due to the persistent proclivity of researchers to place overly one‐sided emphasis on the role of either human agency or preexisting institutions in explaining the process of (de‐)institutionalization and may, at worst, cause functionalist assumptions to be smuggled back into institutional analyses in ways that threaten the hard core of the institutional research program. I discuss how these tendencies can be rectified in future research and how institutional research on MA can be further developed.
