   Sammanfattning : This thesis gives a contribution to strategy-proof social choice theory, in which one investigates to what extent there exist voting procedures that never can be manipulated in the sense that some voter by misrepresentation of his preferences can change the outcome of the voting and obtain an alternative he prefers to that honest voting would give. When exactly one element should be elected from a set of at least three alternatives, then the fundamental result in strategy-proof social choice theory, the Gibbard-Satterthwaite theorem, shows that there in general exists no satisfactory non-manipulable voting procedure.
