On the determinants of political polarization
用贝叶斯模型平均法克服模型不确定性，发现国家内部信任水平和收入不平等是政治两极分化最稳健的决定因素。
In this article, we aim to identify the main determinants of political polarization using Bayesian Model Averaging to overcome the problem of model uncertainty. We find that the level of trust within a country and the degree of income inequality are the most robust determinants of political polarization.
