Exact Sampling for Industry Dynamics and Other Regenerative Processes

In this paper we introduce a technique for perfect sampling from the stationary distribution of possibly non-monotone regenerative processes, such as those that describe industry dynamics (where regeneration corresponds to the process of exit of firms and entry of new ones). The algorithm we propose is a version of coupling from the past that is straightforward to implement, and that exploits the regenerative property of the process in order to achieve rapid coupling.
