Do Transitive Preferences Always Result in Indifferent Divisions?

چکیده
The transitivity of preferences is one of the basic assumptions used in the theory of games and decisions. It is often equated with the rationality of choice and is considered useful in building rankings. Intransitive preferences are considered paradoxical and undesirable. This problem is discussed by many social and natural scientists. A simple model of a sequential game in which two players choose one of the two elements in each iteration is discussed in this paper. The players make their decisions in different contexts defined by the rules of the game. It appears that the optimal strategy of one of the players can only be intransitive (the so-called relevant intransitive strategy)! On the other hand, the optimal strategy for the second player can be either transitive or intransitive. A quantum model of the game using pure one-qubit strategies is considered. In this model, an increase in the importance of intransitive strategies is observed: there is a certain course of the game where intransitive strategies are the only optimal strategies for both players. The study of decision-making models using quantum information theory tools may shed some new light on the understanding of mechanisms that drive the formation of types of preferences.

Approximate Utility Under Perceptual Restrictions
If agents have perceptual limits, and cannot distinguish objects that are sufficiently similar, then immediate problems arise with this notion of rationality. For example, Mas-Colell, Whinston, and Green (1995) provide an example of an agent with limited visual perception, who cannot distinguish a white object from a gray one. Because preferences are assumed to be complete, and because the two ...

If an agent makes sequences of trades of options labeled indiffe...
متن کاملRevealed preference and indifferent selection
It is shown that preferences can be constructed from observed choice behavior in a way that is robust to indifferent selection (i.e., the agent is indifferent between two alternatives but, nevertheless, is only observed selecting one of them). More precisely, a suggestion by Savage (1954) to reveal indifferent selection by considering small monetary perturbations of alternatives is formalized a...
متن کاملTransitivity in Context: A Rational Analysis of Intransitive Choice and Context-Sensitive Preference
Several apparent violations of transitivity have been reported in the literature on decision making. However, these effects have been shown to be compatible with random preference models, in which preferences are transitive at each point in time but vary at random over time. Such models imply that choice proportions will conform to a set of conditions called the triangle inequalities, and no cl...

We consider situations in which agents are not able to completely distinguish between all alternatives. Preferences respect individual objective indifferences if any two alternatives are indifferent whenever an agent cannot distinguish between them. We present necessary and sufficient conditions of such a domain of preferences under which majority rule is quasi-transitive and thus Condorcet win...
