About this paper
Daiki Kawane, Hokuto Nagano, Yoichi Izunaga
The authors develop an inverse method measuring regional priority adjustments needed for an observed allocation to fit a chosen divisor rule. It finds a unique mean-one weight vector by solving for one parameter. In Japan, Adams requires less adjustment than Jefferson across seven elections; its 2024 score is zero because that allocation used Adams. The score is method-relative, not a general measure of fairness.
