Institutional instability imposes a hidden tax on all activity that depends on the institution. Its costs are real, diffuse, and systematically underestimated.
What Instability Costs
Institutional instability — the condition in which the rules, relationships, and operating environment of an institutional system change unpredictably enough that actors cannot plan effectively around them — imposes costs on all activity that depends on the institution. These costs are not fully visible in any single actor's accounts, because they are spread across the entire population of actors who adjust their behaviour in response to the instability. They are not visible in the institutional accounts either, because the institution that generates instability does not bear the costs it imposes on the actors who depend on it. But they are real, they are large in aggregate, and they fall most heavily on the actors who are least able to absorb uncertainty.
The costs take several forms. Investment shortfall is the most economically consequential: actors who would have made investments conditional on the institutional environment remaining stable forgo those investments when they cannot predict whether the institutional environment will support them. The factory not built, the business not started, the career not pursued — each represents value that the instability consumed without any visible transaction. Transaction cost increases accompany every period of institutional uncertainty, as actors build more verification, hedging, and contingency planning into every arrangement that the uncertain environment affects.
Who Bears the Costs
The costs of institutional instability are not borne evenly. Actors with resources — financial reserves, multiple institutional alternatives, and the capacity to absorb uncertainty — can manage instability through diversification and optionality. Actors without resources cannot. They are forced to forgo investments that the stable institutional environment would have made viable, to accept higher transaction costs that they cannot hedge, and to bear the full downside of institutional changes they cannot have predicted. Institutional instability is therefore regressive in its distributional effects: it extracts proportionately more from those who are least able to bear it.
Institutional stability is a public good that is chronically undervalued because its value is invisible when it is present and only legible when it is absent. The institution that is stable is not doing something impressive — it is doing the most basic thing that makes all the activity it governs possible.
