Semantics for Reciprocal Preferences

Semantics for Modelling Reason-Based Preferences

In [13] the authors developed a logical system based on the definition of a new non-classical connective ⊗ originally capturing the notion of reparative obligation. The operator⊗ and the system were proved to be appropriate for rather handling well-known contrary-to-duty paradoxes. Later on, a suitable modeltheoretic possible-world semantics has been developed [4, 5]. In this paper we show how ...

The Evolution of Reciprocal Preferences ∗ Samuel Bowles

A number of outstanding puzzles in economics may be resolved by recognizing that where members of a group benefit from mutual adherence to a social norm, agents may obey the norm and punish its violators, even when this behavior cannot be motivated by self-regarding, outcome-oriented preferences. This behavior, which we call strong reciprocity, is a form of altruism in that it benefits others a...

Generalizing stable semantics by preferences

Different proposals have been made in the literature for refining Dung’s argumentation framework by preferences between arguments. The idea is to ignore an attack if the attacked argument is stronger than its attacker. Acceptability semantics are then applied on the remaining attacks. Unfortunately, these proposals may return some unintended results, in particular, when the attack relation is a...

Conditional Preferences: A New Semantics for Database Queries

Preference queries aim to retrieve from large databases those objects that better match user’s requirements. Approaches proposed so far in the DB field for specifying preferences are limited when one needs to consider conditional, rather than absolute, preferences (e.g., I prefer driving by car in winter, and by motorbike in summer), which are common in context-aware applications. CP-nets are a...
