There is substantial evidence that American voters blame or credit the president for the state of the economy when making electoral decisions. However, a variety of findings on economic voting, cognitive biases in information processing, and party polarization indicate that both objective and subjective economic information should become less important to voters as partisan polarization increases. We evaluate whether partisan polarization attenuates the link between economic performance and citizens’ votes.

美国全国大选的两极分化与经济投票的衰落

有大量证据表明，美国选民在做出选举决定时会为经济状况指责或称赞总统。但是，有关经济投票，信息处理中的认知偏见和政党两极化的各种发现表明，随着党派两极化的增加，客观和主观的经济信息对选民的重要性应降低。我们评估党派分化是否减弱了经济绩效与公民投票之间的联系。
