More precisely, we consider agents that have not only a preference ordering over a set of objects, but also a reliability ordering over the agents themselves; then we study the effects of the public and simultaneous announcement of these individual preferences by defining an operation, the lexicographic upgrade, which receives a collection of preference relations plus a &#8216;priority&#8217; ordering among them, and returns a preference relation. We will review alternative definitions of this lexicographic upgrade, depending on the properties of the priority ordering, and present a sound and complete axiom system for a language describing this operation&#8217;s effects. Time permitting, we will also discuss the effects of the iterative application of this upgrade, focusing in particular on the cases in which preference unanimity can be reached.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Speaker: Fernando R.
