Institutional change is not mysterious. It follows specific mechanisms that are identifiable, analysable, and in some cases designable.
The Change Mechanisms
Institutions change through four primary mechanisms, each of which operates through a different pathway and produces different types of change. Displacement: a new institution replaces the old one, not by reforming it but by substituting for it in the domain where the old institution operated. Layering: a new institutional element is added on top of the existing institution, gradually shifting the institutional balance without formally replacing the old institution. Drift: the institution's formal rules remain unchanged while the context in which those rules operate changes, producing new institutional effects without formal institutional change. And conversion: the existing institution is redirected to new purposes by actors who gain control of it and repurpose its authority and resources toward objectives that differ from the ones the institution was originally designed to serve.
Understanding which mechanism is producing institutional change in a specific context is the analytical prerequisite for assessing whether the change is producing the institutional improvement that the mechanism claims to produce. The layering that appears to add accountability without removing the institutional features that produce the failure is not producing accountability — it is producing the appearance of accountability while the underlying failure mechanisms continue to operate. The conversion that repurposes an institution's authority toward the interests of the actors who have gained control of it is not institutional reform — it is institutional capture dressed in reform language. Distinguishing genuine institutional change from its imitations requires understanding the specific mechanism through which the change is operating.
Institutions change through specific mechanisms that leave specific traces. Understanding the mechanism — not just the formal description of the change — is the analytical prerequisite for assessing whether the change is producing the institutional improvement it claims to produce or whether it is producing the formal record of institutional change while the underlying institutional conditions that produce failure remain intact.
