Legislative Bargaining under Weighted Voting
用非合作博弈模型分析加权投票下的资源分配,发现投票者预期收益与权重成正比,但高权重者过多时低权重者可能因提案权获益,且联盟组建者会获得超额收益,并用1946-2001年联合政府数据验证了组建者效应。
Organizations often distribute resources through weighted voting. We analyze this setting using a noncooperative bargaining game based on the Baron-Ferejohn (1989) model. Unlike analyses derived from cooperative game theory, we find that each voter's expected payoff is proportional to her voting weight. An exception occurs when many high-weight voters exist, as low-weight voters may expect disproportionately high payoffs due to proposal power. The model also predicts that, ex post, the coalition formateur (the party chosen to form a coalition) will receive a disproportionately high payoff. Using data from coalition governments from 1946 to 2001, we find strong evidence of such formateur effects.
