Abstract
This paper presents a new modal logic for ceteris paribus prefer-
ences understood in the sense of "all other things being equal". This
reading goes back to the seminal work of Von Wright in the early 60's,
and it returned in computer science in the 90's and in 'dependency
logics' today. We show how it differs from ceteris paribus as "all
other things being normal", which is used in contexts with preference
defeaters. We provide a semantic analysis and several completeness
theorems. We show how our system links up with Von Wright's work, but
also with the mathematics of dynamic logic. Finally, we discuss
applications to game-theoretic equilibria, and to agenda setting and
preference change.
