Resumo(s)
Arrow proposed a set of conditions for a function
to aggregate ordinal preferences of the
members of a group, proving that it was not possibl
e to satisfy all these assumptions simultaneously.
Later, Keeney adapted these conditions and proposed
a cardinal utility axiomatization for the problem
of aggregating the utility functions. This work dis
cusses the condition of nondictatorship. It propose
s
a stronger formulation for this condition and prese
nts the corresponding characterization of group
cardinal utility functions.
