Using ex post data to estimate the hurdle rate of abatement investments - an application to sulfur emissions from the Swedish pulp and paper industry and energy sector

We propose a method for estimating hurdle rates for firms' investments in pollution abatement technology, using ex post data. The method is based on a structural option value model where the future price of polluting fuel is the major source of uncertainty facing the firm. The econometric procedure is illustrated using a panel of firms from the Swedish pulp and paper industry, and the energy and heating sector from 2000 to 2003. The results indicate a hurdle rate of investment of 2.9 in the pulp and paper industry and 3.4 in the energy and heating sector.
