We give conditions under which a scalar random variable T can be coupled to a random scaling factor $ξ$ such that T and $ξ$T are rendered stochastically independent. A similar result is obtained for random measures. One consequence is a generalization of a result by Pitman and Yor on the Poisson-Dirichlet distribution to its negative parameter range. Another application are diffusion excursions straddling an exponential random time.
