One of the impossibility theorems introduced by Yu ( 2013) can help prove both the Gibbard–Satterthwaite theorem (Gibbard 1973; Satterthwaite 1975) and Arrow’s impossibility theorem (Arrow 1963) succinctly. In this paper, we offer a direct proof of this theorem, which resembles Yu ( 2012) and employs the “pivotal voter ... WebGibbs measure.
