Ideology as Opinion: A Spatial Model of Common-Value Elections
构建了一个共同价值选举的空间模型，将选民的政治分歧归因于对公共利益的信念差异而非利益冲突，并解释了标准视角下令人困惑的民意、意识形态、选举差额和参与模式。
Spatial election literature attributes voters’ political differences to irreconcilable conflicts of interest. Alternatively, voters may merely hold differing beliefs regarding which policies best promote the public interest, as in the classic common-value model of Condorcet (1785). This paper shows how a spatial version of the common-value model explains empirical patterns of public opinion, ideology, electoral margins, and participation that are puzzling from the standard perspective, suggesting that voters may implicitly view politics as a contest between truth and error. If so, this has important consequences for political analysis.
