The Effects of Environmental Regulation on Technology Diffusion:
The Case of Chlorine Manufacturing

Lori Snyder, Nolan Miller, and Robert Stavins

Abstract:  We use a hazard model to estimate the effect of enfironmental regulation on the diffusion of membrane cell production technology in the chlorine manufacturing industry.  We estimate the effect of regulation on both the adoption of the membrane technology at existing plants and on the exist of existing plants using older technologies.  We find that environmental regulation did affect the diffusion of the cleaner technology.  However, it did so not by encouraging adoption, but by reducing the demand for chlorine and hence encouraging the shutdown of facilities using the environmentally inferior options.
