Replication Data for: Contestability, Overcrowding and Electoral competition in Majoritarian Systems

This database includes the data used in the ARDL model describing the equilibrium time path of candidate and party ENP in Canada from 1870 through 2015. The paper is currently in circulation but an early working paper is listed below. The paper is innovative in treating the dynamic structure of party ENP as asymmetric and in doing so uncovers evidence of a long run decline in ENP following WW2 and a rise in the fringe of smaller political parties.

本数据库收录了1870年至2015年加拿大候选人和政党有效政党数（Effective Number of Parties，ENP）均衡时间路径的自回归分布滞后模型（Autoregressive Distributed Lag Model，ARDL）所需数据。该论文目前处于传阅阶段，其早期工作论文已列于下文。本研究的创新之处在于将政党有效政党数的动态结构设定为非对称形式，并借此发现了第二次世界大战（World War II，WW2）后有效政党数长期下滑、小型政党边缘势力有所抬头的实证证据。
