R Function: Calculate unanimity or QMV core sizePosted: January 20, 2013
I have written a little R function for calculating the one-dimensional unanimity / QMV core size given actors’ preferences and vote-weights. The `core’ is a game-theoretic concept which describes the set of all policies or alternatives that cannot be changed given a specific voting rule. The core is often used to describe how difficult a bargaining situation is for actors. The larger the core, the more diverse the interests, and hence the more difficult the bargaining.
The function, a simple example and data on EU Council voting weights can be found in one of my github repository.
