One Man, One Vote
从经济和政治两种视角，为美国选区必须人口相等的“一人一票”原则提供福利依据，并分析党派划分选区者与仁慈划分者对该原则的不同影响。
In the United States, electoral districts must be equipopulous. This requirement is known as the one man, one vote doctrine. We propose welfare-based justifications for this requirement under the economic view, according to which voters care about the policy, and under the political view, according to which voters care about representation. Both justifications assume that the districter is partisan. If the districter is benevolent, one man, one vote is harmless under the economic view but may reduce voter welfare under the political view by as much as the reduction from K to √K districts would.
