Types of Economic Lock-In
Two articles ago, I introduced Gernot Grabher's study of Germany's Ruhr Valley and his finding that the same relationships that built a region's strength also became the mechanism of its decline. I want to slow down this time and go through his three types of lock-in one at a time, because in my experience the third one — political lock-in — is the piece most communities skip past on the way to "let's go recruit something new." And it's usually the piece that has to move first.
Functional lock-in: when suppliers stop being separate businesses
Grabher's first category describes what happens inside the supply chain itself. In tightly bound regional economies, small and mid-sized suppliers become so hierarchically dependent on one or two large customers that they never develop their own research, marketing, or business-development capacity — they become extensions of the core business. That dependency is efficient right up until the anchor customer contracts or leaves, at which point the suppliers discover they have no muscle for finding anyone else.
Cognitive lock-in: when the whole community starts thinking the same way
The second layer is subtler and, I'd argue, more dangerous. Cognitive lock-in describes a shared worldview among the region's business and civic leadership — built from decades of working alongside the same people, solving the same kinds of problems — that quietly narrows what anyone in the room is even able to imagine as a future. It isn't stubbornness exactly. It's that the region's most successful, most trusted people all learned success the same way, and that shared mental model becomes the invisible ceiling on what gets proposed, funded, or taken seriously.
Political lock-in: the layer that actually controls the other two
The third layer is where Grabher's framework becomes directly relevant to how local government and civic institutions operate. Political lock-in describes a tightly knit political-administrative system — local government, chambers, development authorities, utility boards — that has organized itself, often for good historical reasons, around sustaining the dominant industry rather than developing something new. Researchers who've extended Grabher's work describe political lock-ins as thick institutional tissue built specifically to preserve the existing industrial structure, which ends up slowing restructuring and quietly suppressing the community's own latent capacity for something different.
This is the layer that decides whether the other two can ever change. Functional and cognitive lock-in are conditions. Political lock-in is what keeps them funded, staffed, and unquestioned.
Why this is a culture problem, not just a policy problem
Douglass North's work on institutions gives us the mechanism for why this persists so long. North argued that a community's informal constraints — its customs, shared narratives, and inherited mental models — get passed down between generations the same way formal rules do, and that this cultural inheritance is a core reason economies can stay locked onto an inefficient path long after the original logic for that path has disappeared. In practice, that's the retired plant manager still chairing the industrial development board. It's the taxing entity structured entirely around one employer's assessed value. It's the civic calendar still built around a company that hasn't been the town's largest employer in fifteen years.
What has to happen before recruitment starts
None of this means dismantle everything — plenty of that institutional memory is genuinely valuable. It means being honest about which parts of the local political culture exist to serve the community's future and which parts exist to protect a past that's already gone. In my experience, that's usually a leadership composition question before it's a strategy question: who sits on the boards, who gets consulted first, whose approval a new idea needs before it's allowed to be a real idea. A community can write the most sophisticated target industry strategy in the country and still not move, if the people empowered to greenlight it were selected by, and for, the industry that's leaving.
Next time, I want to get into what path creation actually looks like once that groundwork is done — not the theory, but what the first eighteen months tend to require.
