Abstract

The aim of this paper is to find normative foundations of approval voting when individuals have dichotomous preferences. We show that a social choice function is anonymous, neutral, strategy-proof and strictly monotone if and only if it is approval voting and interpret this result as an extension of may’s theorem (econometrica 20:680–684, 1952). Then, we show that approval voting is the only strictly symmetric, neutral and efficient social choice function. This result is related to a characterization of baigent and xu (math soc sci 21:21–29, 1991).
