Why Some Economies Can't Just "Snap Out of It"
Every declining community eventually hears some version of the same advice: diversify, retrain, and attract new industry. Duh!! This is really simplistic advice and it sounds like it’s so easy – that all a community has to do is flip a switch and something different is about to happen. It never happens fast, and in a lot of places it never fully happens at all. I've watched this up close - something holds the economy in place.
Economists have a name for that something: path dependence, and its more stubborn cousin, lock-in.
How an economy gets "stuck"
The idea entered mainstream economics through, of all things, a keyboard. In 1985, Paul David published an account of how the QWERTY layout became standard, arguing that early, largely accidental design choices became locked in through the compounding weight of trained typists, established equipment, and manufacturer habit — not because QWERTY was the best arrangement, but because switching away from it eventually cost more than staying put. (The story I heard was that the first line of keyboard letters spell ‘typewriter’, which it does with a few extra letters.) His core claim was that a path-dependent sequence is one where distant, sometimes accidental, past events can shape outcomes far into the future, independent of whether that path is still the most efficient one available.
Economist Brian Arthur formalized why this happens. In his 1989 paper on competing technologies, he showed that when a technology or industry benefits from increasing returns — large upfront investment, learning-by-doing efficiencies, network effects, and expectations that reinforce themselves — an early, even random advantage can snowball into permanent dominance, regardless of whether a better alternative exists. Once enough capital, skill, and expectation accumulate around one path, the system locks in.
Why this hits regional economies especially hard
This is where it gets personal for those of us in economic development. Gernot Grabher's 1993 study of Germany's Ruhr Valley — coal and steel country — showed that regional lock-in isn't just about physical capital. He identified three reinforcing layers: functional lock-in, where firms grow so tightly interdependent that none can move without the others; cognitive lock-in, where an entire region's shared assumptions about "how business is done here" blind it to emerging alternatives; and political lock-in, where institutions and policy exist to preserve the dominant industry rather than support anything new. His central and somewhat counterintuitive finding was that the region's real strength — dense, trusted, long-standing business relationships — was also precisely what made it so hard to adapt when coal and steel declined. The very networks that built the regional economy became the networks that couldn't let it go.
That's a hard truth for a lot of legacy industrial and resource-dependent communities to sit with. Strong relationships aren't the problem to fix, they're often the mechanism of the lock-in itself.
The nuance economic developers need
Ron Martin and Peter Sunley pushed back usefully on how loosely these ideas get applied. In their 2006 review, they argued that geographers had been borrowing "path dependence" and "lock-in" without fully grappling with the underlying theory, and that regional lock-in is fundamentally place-specific — it has to be explained locally, not assumed. Their more important point for practitioners: we still don't have a good general theory of why some locked-in regions eventually break free and successfully create new paths, while others stay stuck for decades. Escaping lock-in isn't automatic, and it isn't just a matter of time or willpower.
Why this matters for how we do the work
If you're doing economic development in a transitioning community, this literature says something uncomfortable but useful: incentives and marketing campaigns alone don't unlock a locked-in economy. The functional, cognitive, and political layers Grabher identified all have to be addressed, deliberately, at the same time. That's a different kind of practice than traditional site-selection recruitment. It's closer to organizational change, political development or community development.
I'll be writing more on this — including what "path creation" actually looks like in practice for communities trying to build a genuinely new trajectory rather than a slightly modified version of the old one. If you're working through a transition like this yourself, I'd like to hear what's held your community in place.
