Abstract

For committee or multiwinner elections, the Chamberlin-Courant rule (CCR), which combines the Borda rule and the proportional representation, aims to pick the most representative committee (Chamberlin and Courant, 1983). Chamberlin and Courant (1983) have shown that if the size of the committee to be elected is k = 1 among m ≥ 3 candidates, the CCR is equivalent to the Borda rule; Kamwa and Merlin (2014) claimed that if k = m − 1, the CCR is equivalent to the k-Plurality rule. In this paper, we explore what happens for 1
