Bottleneck Control and Network Leverage: How Control of a Point Through Which Routes Pass Becomes Power Over Those Who Need Them

This conceptual paper introduces Bottleneck Control and Network Leverage, the mechanism by which routes to information, goods, or action concentrate in a node and costly alternatives turn control of passage into leverage over dependent users. It examines how network position creates power and exposes people to the consequences of disputes in which they have no part. The account distinguishes structural dependence from the empirical strength of the leverage it creates. The extent of leverage depends on users’ needs, the cost and speed of alternatives, and the willingness of those controlling passage to exercise that control. Explanations of disruption or negotiation are assessed by whether they identify these dependencies and alternatives alongside the conduct of the parties. The paper relates the mechanism to Ronald Burt’s research on structural holes, specifying the stronger condition in which users depend on a bridge and cannot cheaply bypass it. A documented discussion of the January 2009 interruption of Russian gas transit through Ukraine examines concentrated routes, limited alternatives, and downstream exposure. The paper takes no position on responsibility for the dispute. Part of the Relational Conditions and Dynamics series within On Human Modeling, the paper offers questions for tracing routes, assessing alternatives, and identifying who controls access and who bears the costs of disruption.
