This page collects files and computer code for the paper Perfect Simulation for Models of Industry Dynamics by Takashi Kamihigashi and John Stachurski.

In this paper we introduce a technique for perfect simulation from the stationary distribution of a standard model of industry dynamics. The method can be adapted to other, possibly non-monotone, regenerative processes found in industrial organization and other fields of economics. The algorithm we propose is a version of coupling from the past. It is straightforward to implement and exploits the regenerative property of the process in order to achieve rapid coupling.

An implementation is provided in C. The only issue with portability is that the C code uses the GSL library to generate the shocks. However, any other random number generator can be substituted.
