In this thesis, we investigate several issues concerning social choice rules whichsatisfy different degrees of Maskin type monotonicities. Firstly, we introduceg-monotonicity and monotonicity region notions which enable one to comparemonotonicity properties of non-Maskin-monotonic social choice rules. Wecompare self-monotonicities of standard scoring rules and study monotonicityof Majoritarian compromise. Secondly we determine domains of impossibilityand possibility when the individual preferences are clustered around twoopposing norms and the degree of clustering is measured via the Manhattanmetric. In the last chapter we investigate the relation between monotonicityand dictatoriality when agents are allowed to have thick indifference classes.
