The overhead required to coordinate large-scale institutional activity is not friction — it is the price the system pays for collective action.
Coordination as Cost
Every collective action involves coordination costs — the resources consumed in aligning the behaviour of multiple independent actors around a shared objective. These costs are real, they do not approach zero regardless of how well the coordination mechanism is designed, and they scale with the number and heterogeneity of the actors being coordinated. The institution that coordinates a hundred actors with divergent interests spends a meaningful fraction of its total resource budget on the coordination itself, not on the productive activities the coordination is designed to enable.
This coordination cost is the price of scale — the overhead that makes large-scale collective action more expensive per unit of output than small-scale collective action, even when the large-scale activity benefits from efficiencies that the small-scale activity cannot achieve. Understanding this cost structure is essential for institutional design: the question is not how to eliminate coordination costs, which is impossible, but how to design coordination mechanisms that minimise the cost per unit of coordination achieved — and how to ensure that the benefits of large-scale coordination exceed its costs, which they do not always do.
Where Coordination Costs Are Highest
Coordination costs are highest where the actors being coordinated have the most divergent interests, the most information asymmetry between them, and the least established trust and shared framework for resolving disagreements. International institutional coordination faces all three of these conditions simultaneously — sovereign actors with genuinely divergent interests, significant information asymmetry between parties, and limited shared normative frameworks — which is why international institutional action is persistently more expensive and less reliable than domestic institutional action, even when the international objective is as urgent as the domestic one.
Coordination Cost Reduction
Reducing coordination costs without reducing the scale of coordination requires investment in the infrastructure that reduces them: the shared frameworks that reduce the need for bilateral agreement on basic norms, the trust-building relationships that reduce the verification costs of every transaction, the information sharing arrangements that reduce the information asymmetry that makes coordination uncertain and expensive. Each of these investments has a cost in the current period. Each reduces coordination costs in every subsequent period during which the infrastructure is maintained.
Coordination overhead is not waste — it is the minimum cost of collective action. The institution that tries to eliminate it rather than optimise it produces either coordination failure or the illusion of coordination, which is worse.
