1. Essays in Strategy-proof Social Choice Theory
Sammanfattning : This thesis consists of two separate papers in strategy-proof social choice theory. The first paper, “Generalizing the Gibbard-Satterthwaite theorem: Partial preferences, the degree of manipulation, and multi-valuedness”, generalizes the Gibbard-Satterthwaite theorem in three ways: firstly, it is proved that the theorem is still valid when individual preferences belong to a convenient class of partial preferences; secondly, it is shown that every non-dictatorial surjective social choice function is not only manipulable, but it can be manipulated in such a way that some individual obtains either his best or second best alternative; thirdly, we prove a variant of the theorem where the outcomes of the social choice function are subsets of the set of alternatives of an a priori fixed size.

2. Essays on Strategy-proof Social Choice
Sammanfattning : This thesis makes a contribution to strategy-proof social choice theory, in which one investigates the conditions under which it is possible to construct social choice functions (i.e. LÄS MER
