This paper explores the introduction of a variable critical-level in a
variable population context. We focus the attention on the Critical-
Level Leximin criterion, a social evaluation procedure which compares
two social states as follows: (i) It reproduces the Leximin criterion
when applied to vectors of identical dimension and (ii) otherwise, it
completes the smaller one with so many times a variable critical-level
as to make the two vectors equal in size and applies the Leximin criterion again. We prove that the use of a strict monotonic critical-level leads to the intransitivity of the social evaluation criterion. This problem disappears when a weaker monotonicity condition is required. |
