The authors empirically assess whether firms face economies and/or diseconomies of scale with respect to air pollution control by evaluating the effects of production on firmlevel air emission levels using a panel of Czech firms during the country's transitional period of 1993 to 1998. By estimating a separate set of production-related coefficients for each individual sector, the analysis permits economies/diseconomies of scale to differ across sectors. More important, the analysis allows these scale effects to vary over time, which seems critical in the context of a transition economy, as the Czech government was tightening air protection polices by imposing more stringent emission limits and escalating emission charge rates.
