摘要：This paper investigates heterogeneity in pollution abatement costs using a computable generalequilibrium framework. Previous literature using aggregated data has found that "grandfathered"tradable permits are dominated by other instruments including emission taxes, performance standards,and technology mandates because of interactions with pre-existing taxes. However, when theunderlying costs of abatement are heterogeneous, a disaggregate representation of costs yieldsqualitatively different findings. In a disaggregate model of NOXabatement in the United States, therelative performance of tradable permits improves significantly and out-performs command andcontrol approaches over a wide range of emission reductions.
