We propose a simple criterion to compare generalized median voter schemes according to their manipulability. We identify three nec- essary and su¢ cient conditions for the comparability of two generalized median voter schemes in terms of their vulnerability to manipulation. The three conditions are stated using the two associated families of monotonic …xed ballots and depend very much on the power each agent has to unilat- erally change the outcomes of the two generalized median voter schemes. We perform a speci…c analysis of all median voter schemes, the anonymous subfamily of generalized median voter schemes.
