The second question requires that we build an understanding of how the policy instrument effects production and productive efficiency. Our approach is similar to recent stochastic frontier analyses with panel data (Cornwell et al. (1990), Kumbhakar (1990)), which allow intercepts and some coefficients of the production function to vary between firms and over time. Unlike standard production frontier models that assume efficiency measures are stationary, our approach allows us to specify how the pollution levies have affected productive efficiency over time as well as across firms. Intertemporal changes in efficiency are critical for our case since China’s reforms have. | ESPOO 2005 VTT SYMPOSIUM 238 COST ACTION E36 Modelling and simulation in pulp and paper industry Proceedings of Model Validation Workshop VTT SYMPOSIUM 238 Keywords COST Action E36 parameter identification maintenance of models dynamic model validation sensitivity analysis uncertainty analysis pulp and paper industry wet-end chemistry runnability emissions reduction COST ACTION E36 Modelling and simulation in pulp and paper industry Proceedings of Model Validation Workshop Espoo Finland 6 October 2005 Edited by Johannes Kappen PTS Germany Jussi Manninen VTT Finland Risto Ritala Tampere University of Technology Finland Organised by VTT Tampere University of Technology Finland .
