Abstract
Let be a two-sided recurrent Markov chain with fixed initial state and let be a probability measure on its state space. We give a necessary and sufficient criterion for the existence of a non-randomized time such that has the law of the same Markov chain with initial distribution . In the case when our criterion is satisfied we give an explicit solution, which is also a stopping time, and study its moment properties. We show that this solution minimizes the expectation of in the class of all non-negative solutions, simultaneously for all non-negative concave functions .
