Pollution control and technological advance: A dynamic model of the firm

The paper extends the static comparison of effluent taxes and effluent standards to a dynamic world in which firms invest resources in improving their abatement technology as well as their production technology. The analysis shows that the two pollution control policies lead to a distinctly different allocation of research and development (R & D) funds between improvement in abatement technology and improvement in production technology. The model also shows that a temporally constant effluent tax leads to an increasing effluent discharge rate for “typical” firms. Other results concern the pattern of output growth and the rate of technological advance.
