Consider an agent with fuzzy preferences, who has to make exact choices when faced with different feasible sets of alternatives. Confining our analysis to the case of feasible sets with not more than two alternatives, we axiomatically characterize two broad classes of decision rules ('ratio...

Consider an agent with fuzzy preferences. This agent, however, has to make exact choices when faced with different feasible sets of alternatives. What rule does he follow in making such choices? This paper provides an axiomatic characterization of a class of binary choice rules called the...
