This paper studies various ways of changing probability measures with applications to Finance and Insurance. Changes of numéraire and Esscher transforms are considered, just as pricing kernels which are, in a complementary direction, a mean of keeping a privileged probability measure. These approaches are compared and new insights on them are given. This article gives a unifying point of view and makes a synthesis on the subject.
