Dynamic electoral competition with voter loss-aversion and imperfect recall
研究了选民损失厌恶和不完美记忆如何影响两党在多次选举中的政策立场动态，发现初始意识形态变化会引发逐步的极化或去极化过程，与美国国会长期极化趋势一致。
This paper explores the implications of voter loss-aversion and imperfect recall for the dynamics of electoral competition in a simple Downsian model of repeated elections. The interplay between the median voter’s reference point and political parties’ choice of platforms generates a dynamic process of (de)polarization, following an initial shift in party ideology. This is consistent with the gradual nature of long-term trends in polarization in the US Congress.
