Median voters in settings where the policy space is single dimensional and everyone has single peaked preferences are Arrow Dictators.

Question

Quizplus · Accepted Answer

In settings where the policy space is single-dimensional and everyone has single-peaked preferences, the median voter theorem applies, suggesting that the policy preferred by the median voter will win in a majority rule election. This is different from an Arrow dictator, who in Arrow's impossibility theorem, is a single individual whose strict preferences always determine the group's preference under certain conditions. The median voter is not dictating outcomes in the same sense; rather, their preference represents the most preferred outcome when preferences are aggregated under majority rule.
