SPECIALIZED LEARNING AND POLITICAL POLARIZATION
研究了公民因对不同政策议题关注度不同而进行专业化学习，如何导致选民对政党纲领反应减弱，进而加剧政治极化，尤其在社会分歧较大时。
Abstract When citizens are differentiated by how much they care about different issues informing policy, specialization allows them to concentrate their learning on the issues that are most important to them. However, as different citizens focus on different issues, the electorate becomes less responsive to party platforms. In particular, equilibrium policies polarize more in fractionalized societies in which there is greater disagreement about which issues matter the most. When the learning technology allows for more specialization, it effectively transforms the society into a more fractionalized one without changing the underlying preferences of the electorate, thereby increasing polarization.
