Does the winner take it all? Federal policies and political extremism
研究了公民因地区差异而战略性地选举更极端的联邦代表的现象，发现这种战略委托的强度与预期收益呈U形关系，有助于理解国家与欧盟选举中的投票差异。
Whether citizens like or dislike federal policies often depends on regional differences. Because of geography, (economic) history or other path-dependent factors, certain regions are perceived to get more out of the union than others. We show that citizens, therefore, have a strategic incentive to elect Federal delegates that are more extreme than the representative voter. The intensity of such strategic delegation is U-shaped in expected benefits. The predictions of our model hence rationalise the voting differences we observe in the data between national and EU elections.
