Causation and the measurement of power

Abstract This note examines the application of the concept of causation to the con-struction of power indices. It is argued that if the modelling of power relations should capture the causal factors of an outcome then a power index should be based only on the set of minimal winning coalitions. JEL Classification C71, D71 Keywords causation, inus conditions, power indices Power and Cause are the same thing. Correspondent to cause and effect, are POWER and ACT; nay, those and these are the same thing
